+## [Unreleased]
+
+## [1.0.37] - 2026-06-11
+
+This release realigns the npm channel and hardens PAT batch grants. Background on the npm realignment: 1.0.36 was re-cut on GitHub on 2026-06-11 to fold in the canonical-tree poisoned-cache guard (#454), but the npm registry permanently forbids republishing a version number, so the npm package stayed on the original, unguarded cut. 1.0.37 is therefore the first version where **every** distribution channel — GitHub releases, `dws upgrade`, the install scripts, and npm — ships the same guarded build. If you installed 1.0.36 from npm, upgrade to this version.
+
+### Fixed
+
+- **PAT batch grants carry the agent identity and require explicit confirmation** (#455; `internal/pat/chmod.go`, `internal/auth/channel.go`, `internal/app/runner.go`) — an explicit `--agentCode` flag or the `DINGTALK_DWS_AGENTCODE` env var is now carried into PAT batch plan/grant arguments instead of being dropped, and a missing agentCode is forwarded as absent so the PAT core can apply the server-side default rather than failing. Batch grants now refuse to execute without an explicit `--yes` (dry-run and single-scope grants keep their existing behavior), closing the gap where a multi-scope grant could fire without a deliberate confirmation. Only the canonical env name `DINGTALK_DWS_AGENTCODE` is recognized; draft/reversed spellings from earlier iterations are ignored. Verified against prepub: dry-run, single grant, flag-priority grant, and batch grant all resolve the target agentCode, with the granted rows confirmed server-side. Tests: `internal/pat/chmod_test.go`, `internal/pat/browser_policy_test.go`, `test/unit/pat_host_owned_signal_test.go`.
+
+## [1.0.36] - 2026-06-10
+
+This release closes out the poisoned-discovery-cache lock-out for good, with four layers of defense landing together. The lock-out class (seen again on 2026-06-09 as `chat_permission_grant flag redefined: params`): the dynamic command tree is built from cached discovery data **before** Cobra dispatches any command, so a pflag panic fed by a poisoned cache aborted *every* invocation — including `dws cache refresh` and `dws upgrade`, the very commands that could repair it. Now: (1) any panic during the build is recovered instead of crashing (#447), (2) the four known envelope shapes that made pflag panic are skipped at registration so they never fire (#449), (3) when an unknown panic class does fire, the CLI quarantines the poisoned cache and rebuilds itself from a fresh fetch — and `dws upgrade` clears the discovery caches after every binary swap, so simply getting this version onto a machine is enough to escape, no manual cache surgery (#452), and (4) the same guards now also cover the canonical `dws mcp` tree, which is built even earlier and sat outside all three defenses as originally cut (#454 — this release was re-cut on 2026-06-11 to include it; verified against the preserved real poisoned cache from the 2026-05-25 incident). Also in this release: `dws devdoc` gains RAG-backed Open Platform doc search and a new error-diagnosis command (#434), and `dws doc create` stops producing documents with two identical titles (#448).
+
+**Escaping a locked-out older binary**: a binary ≤1.0.35 bricked by a poisoned cache cannot run `dws upgrade`. Either bypass the cache for one invocation with `DWS_CACHE_DIR=$(mktemp -d) dws upgrade`, or delete `~/.dws/cache/<partition>/tools/` by hand, or reinstall via the install script. Once 1.0.36 is on the machine this never needs doing again.
+
+### Added
+
+- **`dws devdoc` — RAG-backed Open Platform doc search and error diagnosis** (#434; `internal/helpers/devdoc.go`, `internal/transport/client.go`) — `dws devdoc article search` now routes to the upstream `search_open_platform_docs_rag` tool, returning structured RAG/reference payloads (the CLI stays a thin invoker; no extra AI analysis layer). New `dws devdoc error diagnose` (alias `troubleshoot`) routes to `search_open_error_code_rag` for diagnosing DingTalk Open Platform API errors, with `--request-id` (hidden `--trace-id` kept for compatibility), `--error-code`, `--error-message`, `--api`, `--context`, `--query`, `--page`, `--size`. Transport-side: query parameters required by DingTalk MCP gateway URLs are preserved on the wire but their values are redacted from debug logs. Default MCP / skill hosts stay on production `https://mcp.dingtalk.com` (prepub remains runtime-configurable). Skill docs (mono + multi `dingtalk-devdoc`) and `docs/command-index.md` updated alongside.
+
+### Fixed
+
+- **CLI no longer bricks when the dynamic command build panics — degrades to built-in commands** (#447; `internal/app/legacy.go`) — `buildEnvelopeCommandsSafe` wraps the envelope-driven build in a local `recover()`. On panic the CLI logs it, prints a stderr hint, and falls back to the hardcoded helper commands, so `auth` / `cache` / `doctor` / `version` / `upgrade` and the helpers stay alive and `dws cache refresh` can rebuild the poisoned cache. Before this, the only recovery from the pre-1.0.32 lock-out class was manually deleting cache files; the duplicate-flag class itself had been fixed at the builder level, but any *future* panic class in the cache-driven build would have bricked the CLI again. Tests: `TestNewLegacyPublicCommandsPanicFallsBackToHelpers`, `TestNewLegacyPublicCommandsNoPanicKeepsDynamicPath`.
+- **Envelope-driven flag registration no longer panics on the four known malformed-envelope shapes** (#449; `internal/compat/registry.go`) — while reproducing the lock-out byte-for-byte, four envelope shapes were found still forwarded to pflag calls that panic, each bricking every invocation: a flag named `params` / `json` colliding with the reserved payload flags (the original `flag redefined: params` — earlier dedup fixes covered the alias list and Detail-schema path but not the primary name); two bindings resolving to the same long flag name across bindings; two flags claiming the same shorthand; and a multi-character shorthand. Two small guards applied at every registration site (`ApplyBindings`, `registerPositionalAliasFlags`): `canRegisterFlag` skips duplicate/reserved long names (the value stays reachable via `--params`), and `safeShorthand` drops an invalid or already-taken shorthand while keeping the long flag. The trailing `--json` / `--params` registration is now idempotent. Defense in depth with #447: the escape hatch should never trigger for these known vectors. Test: `TestBuildDynamicCommandsSurvivesMalformedFlagEnvelope` (5 table-driven vectors).
+- **Poisoned discovery cache now self-heals: quarantine + rebuild on panic, and `dws upgrade` clears discovery caches** (#452; `internal/app/legacy.go`, `internal/app/upgrade.go`, `internal/cache/store.go`) — #447's recovery is upgraded from "degrade and ask the user to run `dws cache refresh`" to a two-stage self-heal: on the first build panic the partition's discovery cache is moved aside to `<partition>.quarantined` (kept on disk for inspection; a previous quarantine is replaced so nothing accumulates — new `Store.QuarantinePartition`) and the build retried once against a fresh fetch. If the retry succeeds the user gets the full dynamic command tree with zero manual steps; only a second panic (remote envelope itself still poisoned, or offline) degrades to helper commands with the `cache refresh` hint. Additionally `dws upgrade` purges discovery-derived caches (`market` / `tools` / `detail` across all partitions — new `Store.PurgeDiscoveryData`) after a successful binary swap, leaving the co-located `downloads/` cache untouched, so an upgraded binary always rebuilds its command tree from fresh data instead of inheriting snapshots written by the old version. Tests: `internal/cache/store_quarantine_test.go`, rewritten `internal/app/legacy_panic_fallback_test.go` (self-heal success, double-panic degradation, no-cache no-op, happy path).
+- **Canonical `dws mcp` tree no longer escapes the poisoned-cache guards** (#454; `internal/cli/canonical.go`, `internal/app/root.go`) — the canonical tree is assembled from cached catalog data *before* the legacy command build, so a pflag panic there — a tool schema property named after the reserved `--params` flag, exactly what the 2026-05-25 incident cache contained — bypassed #447/#449/#452 entirely and still bricked every invocation, including on this release as originally cut. Two layers, mirroring the existing guards: `applyFlagSpecs` skips reserved (`--json`/`--params`), duplicate, and alias-colliding flag names and sanitizes shorthands (`canRegisterToolFlag` / `safeToolShorthand`; a skipped property stays reachable through the reserved JSON payload flags), and `newMCPCommand` wraps the build in the #452 recover → quarantine → retry-once → degrade-to-stub sequence. Verified against the preserved real poisoned cache: the original cut locks out on `--version` / `cache refresh` / `doctor`; this build self-heals on first run and `cache refresh` clears the poison. Tests: `internal/cli/canonical_flag_guard_test.go` (4 cases), `internal/app/canonical_panic_fallback_test.go` (4 cases mirroring the legacy fallback suite).
+- **`dws doc create` no longer produces a document with two identical headings** (#448; `internal/helpers/doc.go`) — the platform renders the document name as the page title, and LLM agents habitually repeat `# <title>` as the markdown body's first line despite the skill docs saying not to, so duplicate-heading documents kept appearing. The `doc create` helper (which wins the envelope merge via `preferLegacyLeaf`) now strips a leading ATX H1 whose text exactly equals `--name` (trimmed, case-insensitive) before forwarding to `create_document`, printing a stderr note so agents learn the convention. Deliberately conservative: only an exact match is removed (`# 背景` stays), ATX closing hashes are handled without over-trimming names ending in `#` (e.g. `C#`), H2+/setext headings are never touched, and a body that is nothing but the duplicate H1 omits the `markdown` param instead of sending an empty string. JSONML bodies are out of scope. Tests: `TestStripLeadingDuplicateTitleHeading` (9 cases) plus three end-to-end cobra tests asserting the exact `markdown` param sent.
+
+## [1.0.35] - 2026-06-08
+
+### Fixed
+
+- **`chat message send` @-mentions not rendered in group / direct chat** (#433, `internal/helpers/chat.go`) — when sending a group message or an openDingTalkId direct message (`send_personal_message`) as the current user, the `content` body was packed with `json.Marshal`, whose default HTML escaping turns the `<` `>` in `<@openDingTalkId>` / `<@all>` into `<` `>`. The DingTalk client renders @-mentions by matching the **literal** `<@...>` token, so after escaping the match fails and the mention shows as plain text — while the API still returns `success`, masking the bug. Fix: add `marshalMessageContent`, which serializes `{title,text}` with `json.Encoder` + `SetEscapeHTML(false)`; both the group and openDingTalkId-direct `send_personal_message` paths now use it, preserving the literal `<@...>`. Added regression test `TestChatMessageSendContentNotHTMLEscaped` asserting the content keeps the literal token and is never HTML-escaped. Verified on a real device: `@someone` and `@all` both render as clickable blue mentions.
+- **`chat` skill docs & scripts aligned to direct-chat `list-direct`** (#424) — `chat message list` now supports group chats only (`--user` / `--open-dingtalk-id` removed); reading a direct chat moves to the dedicated `list-direct` command, but the skill docs and scripts still taught `chat message list --user`, which now errors with `unknown flag: --user`, also breaking `chat_history_with_user.py` (listed as the "preferred" way to query direct chats). This update: `skills/{mono,multi/dingtalk-chat}/references/products/chat.md` switches `message list` to group-only and documents the new `list-direct` command, syncing the intent routing / key-distinction / context-passing tables / caveats; `skills/mono/references/best_practices/01-messaging.md` changes query-private-chat from `list --user` to `list-direct` (the multi version was already updated); `chat_history_with_user.py` (mono + multi) now calls `list-direct` and fixes response parsing (unwraps `result.messages`, aligns `createTime/content/sender` fields — it previously crashed on `'str' object has no attribute 'get'`). Direct-chat sending still uses `chat message send --user` (since v1.0.34 the direct-send rpc is folded into the `send` command; there is no separate `send-direct`). Docs/scripts only; no change to CLI binary behavior.
+- **`pat chmod` batch authorization did not pass through `agentCode`** (#414, `internal/pat/chmod.go`) — the batch plan / grant paths (`buildBatchPlanArgs` / `batchArgs`) previously carried `agentCode` only in the single-grant `toolArgs`; batch calls omitted it, so a batch authorization with an explicit `agentCode` was processed under the default agent. Fix: the batch plan / grant args now also carry `agentCode`, matching the single-grant path.
+- **`pat` JSON output escaped the authorization URL into an unreadable form** (#401, `internal/pat`) — the authorization URL attached to PAT error messages, after default HTML escaping, turned `&` into `&`, breaking the link when copied / recognized on mobile. Fix: the PAT error-enrichment JSON output now uses `SetEscapeHTML(false)` (scoped to PAT JSON only), preserving the readable `&` separators.
+
+## [1.0.34] - 2026-06-03
+
+### Changed
+
+- **Service discovery path now carries a version-coded segment** (`internal/market/registry.go`) — the server-list endpoint moves from `/cli/discovery/apis` to `/cli/discovery/apis/bamboo`. The path is now a single `discoveryAPIPath` constant so future version bumps touch one place. Only the path changes; the MCP base host stays on production `https://mcp.dingtalk.com` and the auth / skill / doctor endpoints are untouched. Discovery via the edition `DiscoveryURL` hook (full-URL `FetchServersFromURL`) is unaffected. Server side must serve the new path.
+
+### Removed
+
+- **`dws aiapp` — AI application product taken offline** — removed the `aiapp` product surface (`create` / `query` / `modify`) from the CLI: deleted `internal/helpers/aiapp.go`, dropped it from the generator coverage targets and `knownRegistryProducts`, removed the `aiapp` skill references (mono `references/products/aiapp.md` + `dingtalk-aiapp` multi skill), and unpublished the `aiapp` server from the service-discovery envelope. Product count drops from 19 to 18.
+
+## [1.0.33] - 2026-06-02
+
+This release merges the multi-contributor `pre-mcp-discovery` feature branch into `main` as a single squash (#391), bringing a large batch of new product surface — full DingTalk **docs** (`doc`), **knowledge base** (`wiki`), **AI app** (`aiapp`), AI-table **forms** + **import/export**, and reworked **mail** / **todo** / **report** command trees — while keeping service discovery pinned to production `https://mcp.dingtalk.com` (the branch's `pre-mcp.dingtalk.com` endpoint change was deliberately excluded; the four host constants in `skill_command.go` / `auth/endpoints.go` / `cli/loader.go` / `market/registry.go` stay on prod). It also folds in the portable auth bundle (`dws auth export` / `import`, #357) and PAT batch authorization (#389).
+
+### Added
+
+- **`dws doc` — full DingTalk document command family** (#387, #362, #388, #390; `internal/helpers/doc.go`, `internal/helpers/doc_jsonml.go`, `internal/helpers/docjsonml/`) — search / list / info / read / create / update / upload / download / copy / move / rename, plus `file`, `folder`, `block`-level editing and `comment` (list / create / reply / create-inline). Authoring supports both DocxXML and a JSONML format with a v2 schema validator (`docjsonml/jsonml-schema-v2.json` + `doc_jsonml_validate_v2.go`). Document export and OA alignment land here.
+- **`dws wiki` — knowledge base management** (`internal/helpers/wiki.go`, `internal/helpers/wiki_proxy.go`) — knowledge space `create` / `get` / `list` / `search` and member `add` / `list` / `update`, routed through a wiki proxy server.
+- **`dws aiapp` — AI application lifecycle** (`internal/helpers/aiapp.go`) — `create` (with prompt / attachments / skills), `query` by task ID, `modify` by thread ID.
+- **`dws aitable` forms + import/export** (`internal/helpers/aitable_form.go`, `internal/helpers/aitable_export_import.go`) — datasheet form management and full record import/export, the latter driven through the async-task helper for large datasets.
+- **Reworked `chat` / `report` / `todo` / `contact` / `mail` command trees aligned to the Wukong baseline** (#355; `internal/compat/mail_hooks.go`, `internal/compat/todo_hooks.go`, `internal/helpers/report_readable.go`) — mail and todo gain dedicated compat hooks; `report` gains a human-readable rendering path alongside the raw JSON, plus deprecation shims for the old report shape.
+- **`dws auth export` / `dws auth import`** (#357) — portable auth bundle for migrating Linux sandbox credentials. Exports the encrypted keychain (`~/.local/share/dws-cli`, including `auth-token.enc` and `dek`) plus required `~/.dws` config so refresh tokens survive import; copying only `app.json` leaves access tokens expiring after ~2 hours. Supports `-o` / `-i` tar.gz paths and `--base64` for copy/paste between sandboxes. `dws auth status` now shows refresh-token validity in table output.
+- **Async-task and paging infrastructure** (`pkg/asynctask/`, `pkg/paging/`) — shared helpers underpinning long-running operations (e.g. aitable import/export, doc export) and cursor/page traversal.
+
+### Changed
+
+- **`envelope` now registers `cli.Aliases` as cobra aliases** (#391) — discovery-generated commands expose their declared aliases natively in the command tree, with accompanying command-structure and JSON-parsing cleanups.
+- **Breaking: `dws pat chmod` prints a compact authorization summary by default, and gains batch authorization flows** (#389; `internal/pat/chmod.go`) — scripts that parse the raw MCP JSON from stdout must now pass `--format json` or `--verbose` to keep the machine-readable payload; the default summary keeps grant status, agentCode, grantType, scope counts, and a next-action hint. New batch grant/plan flows (`pat.batch_grant` / `pat.batch_plan`) authorize multiple products in one session, fall back to the legacy single-grant path when the server reports `PAT_BATCH_AUTH_UNSUPPORTED`, use the server's default `agentCode` when none is given, and surface per-tool authorization metadata for grant planning.
+- **Skill packs synced to the Wukong-aligned content** across attendance / calendar / minutes / oa / sheet and others (#391).
+
+## [1.0.32] - 2026-05-25
+
+Two user-visible regressions resolved plus two AI-agent discoverability fixes. `dws drive upload` was returning `HTTP 403 SignatureDoesNotMatch` for any file whose MIME detects to a non-empty value — basically every real file — because the helper added a client-side `Content-Type` fallback whenever `drive.get_upload_info` returned an empty headers map. DingTalk drive's OSS presigned PUT URLs are signed against an empty `Content-Type` at signing time, so any client-supplied header makes the signature OSS recomputes diverge from the server-signed one, and the PUT is rejected (#347). On Apple Silicon, `dws upgrade` was aborting at the "解压并验证" step with `signal: killed` because GoReleaser cross-compiles `darwin/arm64` binaries on `ubuntu-latest` with no codesign step, and macOS 11+ `amfid` SIGKILLs unsigned arm64 binaries on first exec (#339) — the release pipeline now ad-hoc signs every darwin tarball, and the upgrade client self-heals if it ever encounters an unsigned binary again. On the AI-agent discoverability side, `dws aitable attachment upload-file` (the one-shot prepare + PUT + commit composite) is no longer hidden from `--help` — agents that only browse the command tree were getting stuck at the prepare-only `attachment upload` step, which returns an upload URL + fileToken but doesn't actually upload. And `dws --help` itself now surfaces the missing-command upgrade hint that the custom `renderRootHelp` had been silently dropping from cobra's `root.Long`.
+
+### Added
+
+- **`dws aitable attachment upload-file` is now visible in `dws aitable attachment --help`** (#347, `internal/helpers/aitable.go`) — the hardcoded one-shot composite (prepare + HTTP PUT + commit, returns `fileToken` directly) was previously marked `Hidden:true` and only reachable by agents that read `skills/references/products/aitable.md`. Agents that only discover commands via `--help` were getting stuck at the sibling envelope-generated `attachment upload` (prepare-only): they'd receive `uploadUrl` + `fileToken`, have no idea how to consume the URL, and either write the URL into the attachment field as if it were a token (wrong shape — the field expects `[{"fileToken":"ft_xxx"}]`) or fall back to "please use the UI" messages, which made `dws` look broken even though the capability was fully implemented. Unhiding mirrors the discoverability pattern `lark-cli base +record-upload-attachment` already follows. `Short` is tightened to explicitly mention the 3 steps it bundles; `Long` calls out the prepare-only sibling and recommends `upload-file` as the default for AI agents. The sibling `attachment upload` (prepare-only) keeps its envelope-generated registration but gets a new `Long` that states it is only step 1 of a 3-step flow, lists what an agent must do after (HTTP PUT to `uploadUrl`, then write `[{"fileToken":"ft_xxx"}]` into the attachment field), and points to `upload-file` as the recommended one-shot alternative. `TestAITableUploadFileCommandIsDiscoverable` in `internal/helpers/aitable_upload_file_test.go` guards against re-introducing `Hidden:true`.
+- **`dws --help` root output now surfaces the `dws upgrade` hint when no listed command fits** (#347, `internal/app/root.go` + `internal/app/root_help.go`) — `root.Long` is set to `"提示: 如果遇到能力缺失、命令报错、新功能未注册、或无法完成任务, 请先用 'dws upgrade' 升级到最新版本后再试. 钉钉 OpenAPI 和 dws CLI 持续迭代, 新能力和 bugfix 会先在新版本上线."`. The custom `renderRootHelp` (which replaces cobra's default template to render the services / utilities sections) had been silently dropping `root.Long`; restoring it costs one `Fprintln` after the command list, separated by a blank line. The natural failure mode for both agents and users staring at `dws --help` is to give up or hack around when none of the listed commands fit — but in many cases the right action is simply `dws upgrade`, because new capabilities and bugfixes ship continuously and a missing command is usually a stale-binary issue. `TestRenderRootHelpIncludesLong` in `internal/app/visibility_test.go` uses a sentinel `Long` string and asserts the rendered output contains it verbatim, so any future rewrite of the help renderer that drops `Long` fails this test immediately.
+
+### Fixed
+
+- **`dws drive upload` no longer fails with `HTTP 403 SignatureDoesNotMatch` on any non-empty MIME type** (#347, `internal/helpers/drive.go`) — `httpPutDriveFile` was setting `req.Header["Content-Type"] = fallbackMIME` whenever the prepare_upload response returned an empty headers map. DingTalk drive's OSS presigned URLs sign `StringToSign` against an empty `Content-Type` at signing time, so any client-side header makes the signature OSS recomputes at PUT time differ from the server's presignature, and the upload is rejected with `403 SignatureDoesNotMatch`. This broke every `dws drive upload` for any file whose MIME detects to a non-empty value (`image/png`, `application/pdf`, every common binary) — i.e. essentially every real upload. Fix: drop the `hasContentType` / `fallbackMIME` path entirely, trust the server's headers map as authoritative; empty map means "no client-side headers needed", do not infer. `httpPutDriveFile`'s signature loses the `fallbackMIME` parameter. Manual verification: `curl -X PUT -H "Content-Type:" --data-binary @file <same-presigned-url>` returns `HTTP 200`, proving the only difference was the client-side `Content-Type`. `TestHttpPutDriveFile_NoContentTypeWhenServerHeadersEmpty` guards the empty-map path; `TestHttpPutDriveFile_PassthroughServerHeaders` guards that server-provided `Content-Type` / `x-oss-*` headers are forwarded verbatim. Important: `internal/helpers/aitable.go`'s `upload-file` helper deliberately keeps its `Set("Content-Type", mimeType)` call — its OSS endpoint uses a different signing mode (server includes the client-declared MIME in the signature, verified across 12 file types — all succeed). The two helpers must not be unified without re-validating both endpoints.
+- **`dws upgrade` no longer dies with `signal: killed` on Apple Silicon after fetching the new binary** (#339) — GoReleaser cross-compiles `darwin/arm64` binaries on `ubuntu-latest` with no codesign step, and macOS 11+ on Apple Silicon requires at least an ad-hoc signature on every arm64 binary; `amfid` SIGKILLs unsigned arm64 binaries on first exec, which the upgrade client surfaces as `signal: killed` and aborts at the "解压并验证" step. Two layers of fix:
+  - **Release-side ad-hoc signing** (`scripts/release/post-goreleaser.sh` + `.github/workflows/release.yml`) — after GoReleaser produces the per-platform tarballs, `post-goreleaser.sh` unpacks each `dws-darwin-*.tar.gz`, applies an ad-hoc signature (`codesign --force --sign -` locally, `rcodesign` in CI), deterministically repacks the tarball, and rewrites the matching line in `checksums.txt` so the checksum stays consistent with the resigned tarball. `release.yml` installs `rcodesign 0.27.0` before GoReleaser runs. Every 1.0.32+ tarball ships signed; the install regression is fixed at the source.
+  - **Client-side self-heal in `validateNewBinary`** (`internal/app/upgrade.go`) — when running the freshly-extracted binary returns `signal: killed` on darwin, the validator retries once after running `codesign --force --sign -` on the binary and clearing the `com.apple.quarantine` xattr. This keeps `dws upgrade` working even if a future release ever skips the signing step again, and covers users upgrading from older unsigned binaries. `internal/app/upgrade_test.go` (+80 lines) covers the retry path end-to-end: a stripped binary exits 137 on first exec, `validateNewBinary` recovers via ad-hoc sign + xattr clear, the final binary shows `Signature=adhoc` and runs.
+
+## [1.0.31] - 2026-05-21
+
+Closes the last drive-surface gap with the Wukong edition: `dws drive upload` lands as a single-shot composite (`drive.get_upload_info` → HTTP PUT to OSS → `drive.commit_upload`) so a local file reaches DingTalk drive in one CLI invocation, no manual three-step orchestration. Two more drive commands — `dws drive list-spaces` (list visible drive spaces) and `dws drive delete` (delete a drive file, routed via `serverOverride` to the doc MCP server) — ship via the portal envelope; `dws cache refresh` once to pick them up. Companion skill docs teach the agent to recognise dingpan URLs of the form `alidocs.dingtalk.com/document/edit?dentryKey=…` / `…/document/preview?dentryKey=…` and pass the whole URL through to `--node` instead of trying to extract `dentryKey` by hand (the server interprets `dentryKey` and a bare `nodeId` differently — manual extraction was failing).
+
+### Added
+
+- **`dws drive upload --file <path> [--folder <dentryUuid>] [--space-id <id>] [--file-name <name>] [--mime-type <type>]`** (#335, see `internal/helpers/drive.go`) — composite leaf that runs the full three-step upload internally:
+  1. `drive.get_upload_info` — fetch the OSS-signed `resourceUrl` + `uploadId` + per-URL headers.
+  2. HTTP `PUT` the file binary to OSS (10-minute timeout, attaches every header returned by step 1).
+  3. `drive.commit_upload` — register the new file under the target space / folder.
+
+  `--dry-run` prints the three step invocations as a single JSON payload without making any network calls. `--file -` is rejected on purpose: this is a local-path upload, not stdin streaming. `--folder` only accepts a `dentryUuid`; pure-numeric values are rejected up front (`validateDriveParentID`) so callers don't accidentally pass a chat-link `dentryId` (a different ID namespace) where the drive API expects a `dentryUuid`. Response normalisation handles all the wrapper shapes the upstream returns — `content` / `result` envelopes, `resourceUrls[]` arrays, and the flat `resourceUrl` / `uploadUrl` fallbacks — so the composite produces a stable JSON shape regardless of which path the upstream takes. The helper only registers `upload`; the existing six envelope-generated leaves (`list` / `info` / `download` / `mkdir` / `upload-info` / `commit`) keep flowing through dynamic discovery unchanged. `pickCommands.MergeHardcodedLeaves` guarantees dynamic leaves win on collision, so this helper only fills the upload gap.
+- **`dws drive list-spaces` and `dws drive delete` (envelope rollout)** (#335, ships via portal envelope) — `list_spaces` registers as a plain `cliName` alias on the existing drive MCP server; `delete_document` registers with `serverOverride: doc` so the call routes to the doc MCP server (which owns the delete API), surfacing under the drive command tree for ergonomics. **Existing users must run `dws cache refresh` once** to pick up these two new leaves; no binary upgrade is required for them, but they pair naturally with the v1.0.31 client that ships `upload`.
+- **`skills/references/url-patterns.md`** (#335) — single authority for dispatching `alidocs.dingtalk.com` URLs across doc / sheet / wiki. Five-way split: `/i/p/<token>` short links → expand via `doc info`; `/i/nodes/<id>` node URLs → probe with `doc info` and route by `contentType` / `extension` / `nodeType`; `/spreadsheetv2/...` → `sheet`; `/document/edit|preview?dentryKey=<key>` (dingpan format) → pass the whole URL to `--node`, do not strip `dentryKey` by hand; `/i/share/...` (read-only share) → use the `read_url` fallback. The "URL precheck" Step 0 in `skills/SKILL.md` now redirects every URL-bearing prompt through this dispatcher before the agent picks a product.
+
+### Changed
+
+- **`skills/references/products/doc.md` — `--node` accepts dingpan URLs end-to-end** (#335) — `dws doc info` / `dws doc read` examples gain two extra rows showing `--node "https://alidocs.dingtalk.com/document/edit?dentryKey=<KEY>"` and `…/preview?dentryKey=<KEY>` as first-class `--node` inputs. The "URL recognition & DOC_ID extraction" table adds the `document/edit|preview?dentryKey=<key>` row, and the extraction rules are split into three explicit clauses so the agent stops manually pulling `dentryKey` out of the URL and feeding it as a bare `nodeId` (which the server rejects). The "nodeId dual-format note" upgrades to "nodeId multi-format note" with four equivalent `--node` input shapes side by side.
+
+## [1.0.30] - 2026-05-19
+
+Aligns the open-source CLI with the IM envelope and schema-pipeline plumbing the Wukong edition has been running in pre-prod, plus three user-visible quality-of-life fixes. The most visible one: chat-bot webhook payloads carrying literal Chinese mentions (`@所有人 周报来了` / `@张三 看一下`) no longer fail with `file not found` — `@` is only treated as the `@<filename>` file-injection prefix when followed by an ASCII path-shaped character. The `chat` command tree is refactored to lean on the service-discovery envelope: thin wrappers (`chat search`, `chat group rename`, `chat group members list/add/remove/add-bot`, `chat bot search`) move out of the hardcoded helper and become envelope-generated dynamic commands; the helper keeps only the chat commands with real business logic (intelligent routing, current-user resolution, response normalization, stdin/@file input). A new `dws chat message reply` joins the existing `send` / `send-by-bot` / `recall-by-bot` / `send-by-webhook` family. Underneath: `transform: invert_bool` lets envelopes flip boolean semantics between CLI surface and MCP body (e.g. `--off` ↔ `mute=true`); the pipeline executor fail-fast on upstream `content.errorCode` instead of polling forever; service-discovery dedup keeps two envelope entries that share an MCP endpoint but declare different `cli.id` as separate descriptors (so the `bot-root` / `bot-message` / `bot-group` trio fronting one MCP server stays as three distinct CLI command roots); and `dws chat` no longer nests as `dws chat chat` when two envelope servers both declare the same top-level command name.
+
+### Added
+
+- **`transform: invert_bool` for envelope flag overrides** (#317, see `internal/compat/transform.go`) — flips a boolean at send time. Strings `true`/`1`/`yes`/`on` → `false`; `false`/`0`/`no`/`off`/`""` → `true`. Used when the CLI surface and the MCP body have opposite semantics — e.g. envelope declares `--off` on the CLI but the MCP parameter is `mute=true` for "muted". The framework flips at send time so the envelope keeps the natural CLI verb without forcing every caller to remember the inverted mapping. Coverage in `internal/compat/transform_test.go`.
+- **`dws chat message reply`** (#317, see `internal/helpers/chat.go`) — reply to a chat message. Sits alongside `send` / `send-by-bot` / `recall-by-bot` / `send-by-webhook` under `dws chat message`.
+
+### Changed
+
+- **`chat` command tree refactored to lean on the service-discovery envelope** (#317, commit `6be1247`) — `internal/helpers/chat.go` now only carries the chat commands that need real business logic on top of the raw MCP call: `chat message send` (current-user resolution + symmetric direct/group title validation), `chat message send-by-bot` / `recall-by-bot` / `send-by-webhook` (bot routing + stdin/@file input), and `chat group create` (response normalization). The thin wrappers — `chat search`, `chat group rename`, `chat group members list/add/remove/add-bot`, `chat bot search` — are now produced by the envelope as dynamic commands. Net diff in the helper: `+358 / -71` overall (re-aligning to envelope-owned chat structure), and `chat_test.go` drops 71 lines of test-stubs the dynamic path covers natively. Every previously documented chat command keeps the same flag set and the same MCP tool routing — the surface is just sourced differently.
+- **Pipeline executor fail-fast on `content.errorCode`** (#317, see `internal/compat/pipeline.go`) — when an upstream tool returns a non-empty `content.errorCode`, `executePipelineCall` raises a validation error immediately with the upstream `errorMessage` instead of proceeding into the poll/download phase. Pre-execution cobra validation (`MarkFlagRequired`) only checks that a flag was set, not that its value was non-empty — so a `--required-flag ""` reaches the upstream tool and the upstream rejects with `errorCode`. Without the short-circuit the pipeline kept polling for a task ID that would never exist, either spinning to `PollTimeout` or burning through retries with no actionable error. Exit code 2 (validation), same as any other CLI-layer pre-flight rejection.
+- **Service-discovery dedup keys now include `cli.id`** (#317, see `internal/market/registry.go`) — `NormalizeServers` used to dedup envelope entries by endpoint alone (and by `displayName` in the second pass), which collapsed envelope entries that intentionally split one MCP endpoint into multiple CLI command trees. The `bot-root` / `bot-message` / `bot-group` trio all front the same `.../server/4717...` MCP endpoint and share the displayName `机器人消息`, but each declares a distinct `cli.id` and a distinct CLI command root; the old dedup kept only the last-write and dropped two of them. The dedup key now appends `#<cli.id>` when present, falling back to endpoint / name when absent so historical envelopes without `cli.id` keep their existing behaviour. Coverage in `internal/market/registry_test.go`.
+
+### Fixed
+
+- **`@<text>` injection no longer eats Chinese mentions like `@所有人` / `@张三`** (#317, see `internal/cli/stdin.go`) — `ReadFileArg` and `ResolveInputSource` used to treat *any* value starting with `@` as the `@<filename>` injection syntax. Chat-bot webhook payloads commonly contain literal mentions, so `dws chat message send-by-bot --text "@所有人 周报"` was failing with `file not found: 所有人 周报` before the message reached the API. The new `looksLikeFilePath` heuristic accepts `@` followed by an ASCII path-prefix character (`A-Z` / `a-z` / `0-9` / `.` / `/` / `~` / `_` / `-`), or `@-` for stdin, and passes the value through unchanged otherwise. `@A 但接下来都是中文@测试` *does* still attempt a file lookup because the rune right after `@` is ASCII — this matches the documented `@<path>` prefix shape. The historical "bare `@` is an error" behaviour is preserved. Coverage in `internal/cli/stdin_test.go::TestReadFileArgChineseAtMention`.
+- **`dws chat` no longer nests as `dws chat chat` when two envelope servers contribute the same top-level command** (#317, see `internal/compat/dynamic_commands.go`) — `BuildDynamicCommands` used to overwrite `topLevel[name]` on the second contribution and rely on `attachOrMerge` later, which then attached the *whole* incoming command (named `chat`) under the existing root, producing `dws chat chat <leaf>`. The new `mergeSubcommandsInto` moves the second contribution's *children* under the first root and drops the duplicate wrapper, so e.g. `group-chat` + `im` envelopes that both declare `cli.command: chat` produce a single flat `dws chat` subtree.
+- **Multi-server tool-name authority correction in the runtime runner** (#317, see `internal/app/runner.go` + `internal/app/direct_runtime.go`) — when two envelope servers share the same `cli.command`, the per-product endpoint map `endpoints[cmd]` in `registerDynamicServer` is second-writer-wins, and `catalog.FindProduct` may return the wrong server's endpoint for a tool whose real owner is the *other* server. `runtimeRunner.Run` now cross-checks the canonical tool→endpoint map exposed by the new `directRuntimeToolEndpoint`: when the per-tool endpoint exists and differs from the per-product endpoint the catalog returned, the tool-owner endpoint wins. Pairs with the registry dedup change above so the routing matches the dedup result.
+
+## [1.0.29] - 2026-05-17
+
+Three discovery-envelope products land on the open-source surface — `aiapp` (AI applications), `live` (DingTalk live streaming), and `aisearch` (enterprise people search) — closing the gap with the Wukong edition's product list. The `aisearch` envelope ships rich model-tolerance affordances (short flags, flag aliases, subcommand aliases) so AI agents that hallucinate keyword synonyms (`--query` / `--name` / `--q` / `--text` / `--find`) or alias subcommands (`search` / `find` / `query` / `user` / `people` / ...) still route to the canonical `person` tool instead of erroring out. To support that final fragment of agent tolerance, `internal/compat/registry.go` relaxes the envelope-generated leaf command's `Args` validator from `cobra.NoArgs` to `cobra.ArbitraryArgs` — restoring cobra's own default (`legacyArgs` returns nil for leaves) so trailing positional words are silently ignored. Plus the previously-shipped credential-isolation fix.
+
+### Added
+
+- **`dws aiapp` / `dws live` / `dws aisearch` — three new products discovered via envelope** (no public issue; pre-Diamond rollout) — open-source `dws` now exposes:
+  - **`dws aiapp`** — AI application lifecycle: `create --prompt <p> [--attachments <json>] [--skills <csv>]` / `query --task-id <id>` / `modify --prompt <p> --thread-id <id> [--skills <csv>]`. Backed by upstream `create_ai_app` / `query_ai_app` / `modify_ai_app` MCP tools.
+  - **`dws live stream list`** — list my DingTalk live streams. Backed by upstream `get_my_lives`.
+  - **`dws aisearch person`** — enterprise people search by keyword + multi-dimension filter. Dimensions: `all` (default) / `name` / `department` / `position` / `duty` / `supervisor` / `subordinate` / `phone` / `jobNumber` — multiple comma-separated (`--dimension name,department`). Backed by upstream `enterprise_person_search`.
+  - The `aisearch` envelope additionally registers `-w` / `-d` short flags (keyword / dimension); hidden flag aliases `--query` / `--name` / `--q` / `--text` / `--find` all routing to `keyword`; and cobra subcommand aliases `search` / `find` / `query` / `user` / `people` / `search-person` / `search-user` / `user-search` / `lookup` / `ask` / `contact` all routing to `person`. This closes the F-class model-tolerance regression cases in `dws-wukong/auto-test/cli_to_mcp/testcases/aisearch/test_90_aisearch_param_regression.py` (50/50 pass for aiapp + live + aisearch on the pre-mcp build).
+  - **Users must run `dws cache refresh` once** to pick up the new envelopes; no binary upgrade is required, but pairs naturally with the v1.0.29 client (see Fixed below for the envelope-leaf-Args change).
+
+### Fixed
+
+- **Envelope-generated leaf commands now tolerate trailing positional args** (#306, no public issue) — `NewDirectCommand` in `internal/compat/registry.go` was hard-coding `cobra.NoArgs` for leaves without positional bindings (`totalMax == 0`). This is stricter than cobra's own `legacyArgs` (cobra `args.go:30-32` returns `nil` for any command without subcommands), and surfaced as `unknown command "<word>" for "<leaf>"` whenever an AI agent passed trailing positional words after a leaf — e.g. `dws aisearch person search --keyword "张"` or `dws aisearch person user search --keyword "张"`. Switching the `totalMax == 0` branch (and the initial value) from `cobra.NoArgs` to `cobra.ArbitraryArgs` restores cobra's natural leaf behavior: trailing positional args are silently ignored. Existing positional-binding paths (`MinimumNArgs` / `RangeArgs` / `MaximumNArgs`) are unchanged. Verified against `dws-wukong/auto-test/cli_to_mcp/testcases` — aiapp (9/9) + live (3/3) + aisearch (38/38) = **50/50** pass, vs 48/50 before this patch.
+
+### Security
+
+- **App credential files are partitioned by edition to prevent cross-edition credential leakage** (#300, no public issue; found during internal review) — different `dws` editions sharing the same config directory previously read and wrote the same `app.json`. A sibling edition that pinned its OAuth client ID could persist that ID through the shared post-login path, and the open-source build could later adopt it from the same file. Open-source/empty edition keeps the legacy `app.json` path for compatibility; sibling editions now use `app-<edition>.json`, matching the existing cache partitioning strategy. This prevents new cross-edition app credential writes and reads from colliding. After a sibling edition saves its new partitioned file, it also best-effort removes a legacy `~/.dws/app.json` only when that file's `clientId` matches the sibling edition being saved; a different, unparsable, or otherwise unowned `app.json` is left untouched to avoid deleting open-source credentials. If you previously ran multiple editions in one shared `~/.dws`, remove any confirmed-stale orphan manually with `rm ~/.dws/app.json` after verifying it is not the open-source credential file you still need.
+
+## [1.0.28] - 2026-05-14
+
+A single symmetric follow-up to 1.0.26's #250: `dws chat message send --group <cid>` now refuses an empty `--title` at the CLI layer instead of letting the call fall through to the API and surface a misleading `发群服务窗会话消息失败` error. No other behaviour changes.
+
+### Fixed
+
+- **`dws chat message send` rejects missing `--title` on group messages** (#294, completes #250) — `send_message_as_user`'s schema marks `title` as required (just like `send_direct_message_as_user`), but `buildChatMessageSendInvocation` only had the pre-validation on the direct-message branches. Group sends without a title were falling through to the API and returning the same misleading `发群服务窗会话消息失败` that #250 already fixed for direct messages. The check now covers both branches: missing `--title` on `--group` returns `--title is required for group messages (--group)` with exit code 2; missing on `--user` / `--open-dingtalk-id` keeps the original `--title is required for direct messages (--user / --open-dingtalk-id)`. The `Long` help, `--title` flag description, the first `Example`, and `skills/references/products/chat.md` (including the drive→chat workflow example) are realigned to "title is required for both direct and group messages" — the docs previously contradicted themselves (the prose said 群聊可选 while the flag listing said 必填). `internal/helpers/chat_test.go` adds a `group-without-title` rejection case; the existing `group` / `positional-text` success cases now pass `--title` to stay aligned with the new validation. No API request shape change — the server has always required `title`; the CLI now matches.
+
+## [1.0.27] - 2026-05-14
+
+Two user-visible fixes plus the schema primitive they're built on. `dws doc update` now reads Markdown from a file or stdin, so long / multi-line / table-heavy content no longer gets mangled by shell escaping; `dws sheet find --query` stops returning `unknown flag` on the open-source build, restoring copy-paste from internal wukong docs. Underneath, schema/discovery envelopes get a generic `file_read` transform and a `CLIFlagOverride.MapsTo` field that lets two sibling CLI flags route into the same MCP parameter slot. Also suppresses a noisy WARN on normal stdio-plugin shutdown.
+
+### Added
+
+- **`file_read` transform + `CLIFlagOverride.MapsTo` field** (#291, closes #277 #278 #282 #288) — discovery envelopes can now declare a path-typed CLI flag that performs the "file path → file contents string" conversion client-side before the value reaches the upstream MCP parameter.
+  - `transform: "file_read"` (`internal/compat/transform.go`) — reads the file at the flag's value with UTF-8 validation; `-` means stdin. Any IO / encoding failure is surfaced as a validation error (exit 2), distinct from the generic transient-failure path (exit 1).
+  - `CLIFlagOverride.MapsTo` (`internal/market/registry.go`) — redirects the flag's final value (post-transform or literal) into a named MCP parameter slot instead of the default `params[propertyName]`. This lets a single MCP parameter (e.g. `markdown`) be fed by two sibling CLI flags — a literal `--content` and a file-reading `--content-file` — paired with the existing tool-level `MutuallyExclusive` / `RequireOneOf` to express "exclusive, at least one".
+  - Wired into the `internal/compat/dynamic_commands.go` normalizer via a separate `mapsToRoutes` collection + routing pass; empty `MapsTo` preserves the legacy `params[propertyName] = value` semantics, so every pre-existing dynamic_commands test passes unchanged. Pre-prod end-to-end verified across 6 cases (see PR #291's Validation table).
+- **`dws doc update --content-file <path>` (envelope rollout)** — fixes "long Markdown can't reach the doc". The old command only accepted `--content "..."`, so long / multi-line / table-heavy Markdown got mangled by shell escaping and AI agents writing >2KB of content were stuck. The envelope now maps both `--content` (literal) and `--content-file` (`file_read` transform) to the `markdown` parameter, makes them mutually exclusive via cobra's `MarkFlagsMutuallyExclusive`, and requires at least one via `RequireOneOf`. `--content-file -` reads from stdin, so `cat long.md | dws doc update --content-file -` works directly. **Existing users must run `dws cache refresh` once** to pick up the new envelope.
+- **`dws sheet find --query` hidden alias (envelope rollout)** — fixes "unknown flag when copy-pasting commands across editions". Users copying `dws sheet find --query "..."` from internal wukong docs onto open-source `dws` got `unknown flag: --query`, because the open-source primary flag is named `--find`. The envelope now registers `--query` as a hidden alias of `--find` via `CLIFlagOverride.Aliases` (the field shipped in 1.0.26) — it doesn't show up in `--help`, but accepts values and writes to the same MCP parameter. `--find` behaviour is unchanged. Also requires `dws cache refresh` once.
+
+### Fixed
+
+- **Noisy `failed to stop stdio client: exit status 1` WARN on normal stdio-plugin shutdown** (#285) — when `Stop()` explicitly `Kill`s the subprocess, the non-zero exit code returned by `cmd.Wait()` is expected behaviour, but it was being propagated as an error and logged to stderr on every CLI exit, polluting agent log parsing. `Stop()` now returns `nil` after Kill + Wait; the error path is reserved for "process exited on its own with non-zero" (e.g. stdin close without an explicit Kill). `internal/transport/stdio.go` + `stdio_integration_test.go` assert "Stop() returns nil after kill".
+
+## [1.0.26] - 2026-05-12
+
+Platform-stability round: Windows PAT-auth browser opener no longer truncates URLs at `&userCode=`, macOS sandbox hosts get an opt-in keychain fallback, and `dws doc download` rejects `axls` nodes before requesting `drive:download` consent. Two new global output formats `-f ndjson` and `-f csv` (matching `larksuite/cli`) land as first-class citizens with real-traffic-verified list detection. The `dws doc comment *` regression tracked in #240 is also resolved — fix is in the market metadata, users just need `dws cache refresh` once.
+
+### Added
+
+- **`-f ndjson` and `-f csv` global output formats** (#259, closes #252) — `ndjson` emits one compact JSON record per line (works straight with `jq -c` / `while read` / log pipelines); `csv` goes through `encoding/csv` (RFC-4180 — quoting, embedded newlines, CJK all handled by stdlib) and reuses the existing `-f table` column resolver (`normalizePayload` / `unwrapPrimaryObject` / `extractRowsFromMap` / `rowsFromSlice` / `formatValue`) so table and csv stay visually aligned. After a 7-product real-traffic sweep (contact / chat / doc / mail / todo / minutes / schema), the `preferredListKeys` whitelist was extended to cover the actual DingTalk envelope shapes — `contact user search` (`result`), `chat search` (`result.value`), `doc search` (`documents`), `mail mailbox list` (`emailAccounts`), `todo task list` (`result.todoCards`) — so these commands now degrade into a proper row stream instead of collapsing to a single-line `key,value` blob. Lives in `internal/output/ndjson.go` + `internal/output/csv.go`; `--format` help in `internal/app/flags.go` now lists `ndjson|csv` alongside `json|table|raw|pretty`.
+
+### Changed
+
+- **Sticky flag splitting is now schema-aware** (#272) — PreParse `StickyHandler` 此前会把任何前缀命中已知 flag 的 `--flagsuffix` 一律切成 `--flag suffix`，于是 `--starttime20260507` 这类拼错被静默改写成 `--start time20260507`，把假值传到下游。新行为按 flag 的 pflag 类型 / JSON Schema `format` / `enum` 校验 suffix 是否像合法 value（共享逻辑见 `pkg/cmdutil/sticky_suffix.go`），不像就保留原 token 让 cobra 报 `unknown flag`。slice/array/object 类型的 flag 永不切分。首 rune 读取使用 `utf8.DecodeRuneInString`，对中文等多字节 value 安全。
+
+### Added
+
+- **`available_flags` field on unknown-flag errors** (#272) — `dws -f json` 的 unknown-flag 错误体里新增 `available_flags`（已排序、过滤掉 hidden 与内部 `json` / `params`），方便 agent 不解析 `--help` 就能恢复。Human-readable 输出会附 `Flags: ...` 行，截断在 200 字节内。
+
+### Fixed
+
+- **`dws chat message send` 单聊缺 `--title` 时前置校验** (#250) — 单聊（`--user` / `--open-dingtalk-id`）的底层工具 `send_direct_message_as_user` 在 API 层强制要求 title，缺失时返回误导性的 `发群服务窗会话消息失败`。CLI 现在在 `buildChatMessageSendInvocation` 里前置校验，直接返回 `--title is required for direct messages (--user / --open-dingtalk-id)`；同时把 `Long` help、`--title` flag 描述、Example 和 `skills/references/products/chat.md` 全部对齐为「单聊必填，群聊可选」。群聊行为不变。
+- **PAT auth URLs were truncated on Windows browser open** (#242, fixes #230) — `cmd /c start <url>` on Windows interprets `&` as a command separator, so PAT URLs containing `&userCode=...` were silently chopped before the userCode segment, and the browser landed on a 0-permission DingTalk page. The retry opener now uses `rundll32 url.dll,FileProtocolHandler`, which passes the URL through verbatim. The PAT response also exposes a copy-safe `data.authorizationUrl` (in addition to the service-provided `data.uri`, which is preserved as-is), and human-readable PAT output prints `PAT_AUTHORIZATION_URL=<full-url>` on its own line so OpenClaw-style host wrappers that swallow or reformat stderr can still capture the full link. Legacy DingTalk hash-route shapes (`https://open-dev.dingtalk.com/fe/old#%2FpersonalAuthorization%3FflowId=...%26userCode=...`) are normalised back into the working `/fe/old?hash=...#/personalAuthorization?...&userCode=...` form. Regression tests cover the issue-shaped URLs (encoded hash, fragment, `&userCode`) plus the OpenClaw malformed-hash variant.
+- **`dws doc download` triggered `drive:download` PAT consent for unsupported axls nodes** (#268, fixes #190) — added a `get_document_info` preflight before `download_file`, so online-sheet (`axls`) nodes are rejected locally with guidance to use sheet range tools instead. The preflight reads `extension` from deterministic response paths (no recursive payload scan) and routes its own PAT errors back through `handlePatAuthCheck`, preserving device-flow / host-owned PAT behaviour. Costs one extra MCP roundtrip per `doc download` — deliberate, so the unsupported path fails before consent. Lives in `internal/app/doc_download_preflight.go`; coverage in `internal/app/runner_test.go`.
+- **macOS sandbox hosts (Codex App etc.) couldn't read/write tokens via Keychain** (#267, fixes #214) — sandboxed macOS environments intercept `security` / Keychain APIs, so every token operation failed. New opt-in `DWS_DISABLE_KEYCHAIN=1` switches macOS to the same file-DEK path Linux uses (DEK at `~/Library/Application Support/dws-cli/dek`, mode `0600`), bypassing the system Keychain. Default behaviour is unchanged — fallback is strictly opt-in because file-DEK is a weaker trust model than Keychain-managed storage (DEK file sits next to ciphertext in the same directory). The Darwin / Linux file-DEK implementation is now shared in `internal/keychain/file_dek.go` (Linux path deduplicated by ~40 lines). Documented in `docs/reference.md` (中英) with the security tradeoff spelt out so users make the choice explicitly.
+- **`dws doc comment {list,create,create-inline,reply}` returned `PARAM_ERROR - 未找到指定工具`** (fixes #240, also #234) — the four comment tools used to live on an independent `doc-comment` MCP server. After the Portal merged comment functionality into the `doc` server descriptor, the runtime `tools/list` on the merged `doc` server didn't include them, so every `dws doc comment *` call returned the "tool not found" PARAM_ERROR. The market metadata for the `doc` server now declares `serverOverride: "doc-comment"` on all four comment `toolOverrides`, so the existing CLI routing path sends `dws doc comment *` to the still-running `doc-comment` MCP server (which has the tools). No CLI code change was required, but **existing users must run `dws cache refresh` once** to pick up the updated descriptor — without that, the stale local market cache keeps pointing the call at the merged `doc` server and the error persists. Verified post-refresh: dry-run resolves to `https://mcp-gw.dingtalk.com/server/doc-comment` with tool `list_comments`, real calls return normal business responses (e.g. legitimate cross-org authz errors) instead of `未找到指定工具`.
+
+## [1.0.25] - 2026-05-11
+
+Two generic envelope-schema enhancements that close gaps the `cli_to_mcp` test suite kept surfacing — both product-agnostic, no hardcoded helper commands. Plus missing skill references for the already-registered `sheet` and `wiki` products are now shipped.
+
+### Added
+
+- **`sheet` (在线电子表格) skill reference + product-overview entry** — the `sheet` product registers **34 envelope tools** covering worksheet CRUD (`create` / `new` / `list` / `info` / `copy_sheet` / `update_sheet`), range read/write (`range read` / `range update` / `append`), dimension ops (`add-dimension` / `insert-dimension` / `delete-dimension` / `move-dimension` / `update-dimension`), merge (`merge-cells` / `unmerge-cells`), find/replace (`find` / `replace`), filter views (`filter-view {create, list, update, delete, update-criteria, delete-criteria}`), sheet-level filters (`create_filter` / `get_filter` / `update_filter` / `delete_filter` / `set_filter_criteria` / `clear_filter_criteria` / `sort_filter`), image write (`write-image`), and async export (`submit_export_job` + `query_export_job`). These were live in the envelope but `skills/references/products/sheet.md` had not shipped and `skills/SKILL.md` 产品总览 didn't list `sheet`, so agents had no reference to consult and were skipping it during intent routing. This release adds the doc, registers `sheet` in 产品总览 + 意图判断决策树, extends `description` to include 在线电子表格, adds a Sheet row to `README.md` / `README_zh.md` "Key Services", and notes the v1.0.25 reality on naming (about a third of `sheet` tools still expose snake_case cli_names pending `CLIAliases` (#246) rollout) and on export (no consolidated `dws sheet export` exists in v1.0.25 — `submit_export_job` + `query_export_job` are the atomic primitives; Pipeline (#247) provides the future plumbing).
+- **`wiki` (知识库) skill reference + product-overview entry** — the wiki product's 7 envelope tools (`wiki.create_wikiSpace`, `wiki.get_wikiSpace`, `wiki.list_wikiSpaces`, `wiki.search_wikiSpaces`, `wiki.add_member`, `wiki.list_member`, `wiki.update_member`, surfaced as `dws wiki space create / get / list / search` and `dws wiki member add / list / update`) have been registered for a while, but no `skills/references/products/wiki.md` shipped with them, so agents had no per-command reference to consult. This release adds the reference doc, registers `wiki` in `skills/SKILL.md`'s 产品总览 table and 意图判断决策树, mentions 知识库 in the skill `description` frontmatter, adds a Wiki row to `README.md` / `README_zh.md` "Key Services", and removes `wiki` from the "Coming soon" callout (which was now stale).
+- **`CLIToolOverride.CLIAliases` envelope field** (#246) — lets a single MCP tool register additional cobra command aliases via envelope JSON (e.g. `range read` also accepts `range get`, `member list` accepts `member ls`). Plumbed through the existing `Route.Aliases → cobra.Command.Aliases` path; sibling conflicts are silently dropped by cobra. Lives in `internal/market/registry.go` + `internal/compat/dynamic_commands.go`.
+- **`json_parse_strict` transform** (#246) — strict-JSON variant of `json_parse` that does **not** fall back to YAML. Use when the upstream tool requires a structured array/object and silently coercing a malformed input to a scalar string would mask a real user error (observed: `filter-view --criteria 'NOT_VALID_JSON'` was being accepted and quietly creating an empty-criteria view). In `internal/compat/transform.go`.
+- **`CLIToolOverride.Pipeline` + pipeline executor** (#247) — a single CLI command can now orchestrate an ordered sequence of MCP tool calls plus optional HTTP-download sinks, declared entirely in envelope JSON. Motivating use case: the "submit-job → poll-status → download-result" pattern (e.g. sheet export) that previously required per-product hardcoded helpers.
+  - `PipelineStep` supports `type:"call"` (with optional `PollUntilField` / `PollUntilValue` / `PollIntervalSec` / `PollTimeoutSec` for polling loops) and `type:"download"` (resolves `DownloadURLField`, HTTP GETs the body, writes to the path from `OutputFlag`, infers filename for directory paths).
+  - Template language: `$flag.<name>` resolves a user CLI flag by alias; `$step.<idx>.<dotPath>` walks a prior step's response (works through wrapped MCP envelopes); literals pass through.
+  - `CLIFlagOverride.PipelineLocal` marks a flag as CLI-side only so `CollectBindings` skips it (value never reaches MCP params); the pipeline executor still reads it via `extractFlagValuesByAlias`.
+  - Download step emits machine-parseable plain-text lines (`jobId: <id>\n`, `downloadUrl: <url>\n`) alongside the standard JSON envelope, so shell pipelines and regex-based tests can extract key values without JSON parsing.
+
+## [1.0.24] - 2026-05-09
+
+Three small but user-visible safety/usability changes: the embedded distribution now refuses to self-upgrade, the `dws auth login` help text finally matches the actual default flow (loopback, not device), and the release workflow gains a manual fallback trigger.
+
+### Changed
+
+- **`dws upgrade` is blocked in embedded distributions** (#248) — when the CLI is shipped as an embedded asset (e.g. inside another product), `dws upgrade` would happily overwrite the host-managed binary. The upgrade entry point now detects the embedded build flag and exits early with a clear message; covered by `internal/app/upgrade_embedded_guard_test.go`.
+
+### Docs
+
+- **`dws auth login` help text reflects the real default** (#238, fixes #226) — the long help previously claimed "OAuth 设备流 (默认)", but the actual default starts a 127.0.0.1 loopback listener and only switches to device flow when `--device` is passed. SSH-into-headless-Linux users following the old text hit a dead end (remote-side 127.0.0.1 is unreachable from the local browser). Help and two `flagErrorWithSuggestions` messages in `root.go` are realigned: each method is named after its real flag (`OAuth Loopback 流 (默认)` / `OAuth 设备流 (--device)` / `直接提供 Token (--token)`), with an explicit `--device` example for SSH/headless. No behaviour change.
+
+### CI
+
+- **`workflow_dispatch` trigger added to release workflow as a fallback** (#261) — GitHub occasionally drops tag-push events; the release job can now be re-run manually against any tag ref without having to delete and re-push the tag.
+
+## [1.0.23] - 2026-05-08
+
+A single fix for HTTP proxy support across the CLI's custom HTTP transports. No behaviour changes elsewhere.
+
+### Fixed
+
+- **`HTTP_PROXY` / `HTTPS_PROXY` environment variables silently ignored by all custom transports** (#237, fixes #236) — the three custom `http.Transport` instances built by the CLI (`internal/transport/client.go` MCP transport, `internal/apiclient/client.go` DingTalk OpenAPI client, `internal/app/legacy.go` IPv4-forcing registry client) all set `DialContext` / `TLSClientConfig` / timeouts but omitted the `Proxy` field. Per Go's `net/http` contract, a non-nil Transport without an explicit `Proxy` means "no proxy" — env vars are silently ignored, breaking sandboxed or air-gapped deployments that route outbound through `HTTP_PROXY` / `HTTPS_PROXY`. All three transports now set `Proxy: http.ProxyFromEnvironment`.
+
+### Tests
+
+- Per-package regression test that pointer-compares the Transport's `Proxy` func against `http.ProxyFromEnvironment`, avoiding flakiness from Go's `envProxyOnce` memoisation when running alongside tests that read proxy env early. (#237)
+
+## [1.0.22] - 2026-05-07
+
+Two release-blocking bug fixes: `dws attendance summary` now exposes the server-required `--stats-type` flag (without it, every call returned C0002), and the install scripts finally populate `~/.hermes/skills/dws/` for users who already have Hermes.
+
+### Fixed
+
+- **`dws attendance summary` returned C0002 (统计类型错误) on every call** (#228, fixes #227) — the DingTalk MCP tool `get_attendance_summary` requires `statsType` at the business layer even though the schema marks it optional. The CLI did not expose any way to set it, so the command was 100% unusable. A new `--stats-type` flag (`week` / `month`) is now plumbed through to `QueryUserAttendVO.statsType`; the flag is documented as required in the long help, flag description, and `skills/references/products/attendance.md`.
+- **Install scripts skipped `.hermes/skills/` when populating skill directories** (#221, fixes #188) — the `AGENT_DIRS` lists across `build/npm/install.js`, `scripts/install.sh`, `scripts/install.ps1`, `scripts/install-skills.sh` and the four upgrade-path mirrors (8 sources total once review feedback was addressed) did not include `.hermes/skills`, so users with Hermes installed were not getting `~/.hermes/skills/dws/` populated automatically. The existing parent-directory gate keeps this zero-side-effect for users without Hermes.
+
+### Tests
+
+- New `--stats-type` regression coverage in `test/cli_compat/attendance_test.go` — verifies `statsType` is written to `QueryUserAttendVO` when set to `month` or `week`, and is omitted when not provided. (#228)
+
+## [1.0.21] - 2026-05-05
+
+A single critical routing fix for `dws drive` commands. No new commands or behaviour changes elsewhere.
+
+### Fixed
+
+- **`dws drive mkdir` / `dws drive download` silently routed to the doc MCP server** (#220, fixes #219) — when two MCP servers register tools with the same name (e.g. both `drive` and `doc` expose `create_folder`), the tool-level endpoint map used last-writer-wins, so drive-side calls landed on the doc endpoint and returned mock-shaped responses (`success: true` with a fake `folderId`) without actually creating anything. `directRuntimeEndpoint` now resolves product-level first when the caller already knows the productID, and only falls back to the tool-level lookup when productID is empty. The wrong-server collision and the resulting "succeeded but didn't" behaviour are gone.
+
+## [1.0.20] - 2026-05-04
+
+Documentation polish and a login regression fix. No behaviour changes outside the login MCP refresh path.
+
+### Fixed
+
+- **Login no longer reuses stale `clientId` from an old MCP cache** (#213) — `dws login` now unconditionally re-fetches the MCP descriptor, so a previously cached client id can't keep producing auth errors after the server rotates it.
+
+### Docs
+
+- **`dws chat message list` pagination** (#218, fixes #195) — clarifies that `nextCursor` is opaque and must be passed back as `--cursor` exactly; warns against parsing or reusing it as an offset.
+- **`dws contact search` examples** (#209) — switched from the removed `--keyword` flag to the current `--query`.
+- **`dws todo` help text** (#205) — expanded field semantics so MCP wrappers generate accurate schemas.
+- **`dws chat message send-by-bot` and `dws report create` help** (#217, #106, #107) — `--robot-code` / `--title` / `--text` now carry the `(必填)` marker; `report create --contents` documents the `key=field_name` requirement and rewrites examples as a `template detail → create` two-step pipeline.
+- **CHANGELOG backfill for 1.0.19** (#204).
+
+## [1.0.19] - 2026-04-30
+
+Discovery hardening for edition overlays: `edition.SupplementServers` / `FallbackServers` hooks now consistently surface through the **runtime catalog loader**, not just the static command tree, so overlay products that live outside the Portal envelope (e.g. Wukong gray-release `conference`) resolve an endpoint on both the cold-cache and tool-not-in-catalog paths. Ships with per-edition cache partitioning to stop cross-edition disk-cache leakage, plus a small todo fix.
+
+### Added
+
+- **`pkg/config.EditionPartition(name)`** (#197) — returns the cache partition key for a given edition. Open-source core (`""` / `"open"`) keeps using `DefaultPartition` (`default/default`); every other edition gets its own namespace (`<edition>/default`), preventing cross-edition data leakage in the shared `~/.dws` disk cache. Lives in `pkg/config` as a leaf helper so `internal/cli`, `internal/app`, and `internal/cache` can all call it without risking import cycles.
+- **`internal/editionmerge` shared package** (#197) — single source of truth for converting `edition.ServerInfo` into `market.ServerDescriptor` (`ToDescriptor`) and for merging `SupplementServers` / `FallbackServers` into a descriptor list. Both `internal/cli` (command tree) and `internal/app` (runtime catalog) now apply the edition hooks against the same discovery pipeline.
+
+### Changed
+
+- **`EnvironmentLoader.loadFromCache` honors `SupplementServers` even on empty registry** (#197) — when the Portal registry cache is missing or empty, the catalog loader still materialises the edition's `SupplementServers` as endpoint-only `discovery.RuntimeServer` entries (source: `edition_supplement`), so hardcoded overlay commands for supplement-only products can still resolve an endpoint via the catalog path. Previously `loadFromCache` short-circuited to an empty catalog whenever the registry snapshot was empty, silently dropping gray-release products.
+- **Cache loader switches from `DefaultPartition` to `EditionPartition(edition.Get().Name)`** (#197) — the runtime catalog, registry snapshot, and tools snapshot are now partitioned per edition instead of all editions sharing `default/default`.
+- **`loadFromCache` appends supplement servers alongside fresh-cache servers** (#197) — supplement entries whose `CLI.ID` / `Key` are already present in the cached registry are skipped, so the hook never shadows Portal-published servers; only new products are added.
+- **`runtimeRunner.Run` falls through to `directRuntimeEndpoint` for supplement products** (#197) — when the catalog contains the product (e.g. supplied by `SupplementServers`) but the specific tool is not declared, the runner now trusts `directRuntimeEndpoint` to resolve a working endpoint for the tool before returning the explicit catalog-miss error. Supplement entries intentionally carry no tool list, so this is the path that makes overlay-only tools executable.
+- **Legacy `mergeSupplementServers` / `fallbackToDescriptors` moved out of `internal/app/legacy.go`** (#197) — relocated into `internal/editionmerge` and reused by the catalog loader, eliminating the duplicate `edition.ServerInfo → market.ServerDescriptor` logic that previously only ran on the static command-tree path.
+
+### Fixed
+
+- **`dws todo task get` returns empty** (#202) — the helper was calling `query_todo_detail`, which is not a valid MCP tool and returns empty. Switched to `get_todo_detail` as declared in `discovery.json`, restoring correct task-detail behaviour.
+- **Conference and other Wukong gray-release products miss endpoint on cold cache** (#197) — products registered only via `edition.SupplementServers` (not yet in the Portal envelope) now resolve an endpoint through the catalog path in both cold-start and tool-not-declared scenarios.
+
+### Tests
+
+- `internal/editionmerge/merge_test.go` — descriptor conversion + supplement/fallback merge semantics.
+- `internal/cli/loader_partition_test.go` + `loader_supplement_test.go` — edition-partitioned cache reads and supplement hook surfacing from `loadFromCache` (including empty-registry cold path and existing-ID deduplication).
+- `internal/app/legacy_wukong_partition_e2e_test.go` — end-to-end cache partition isolation for the Wukong edition.
+- `internal/app/runner_supplement_fallback_test.go` — runner falls through to `directRuntimeEndpoint` when the tool isn't declared by a supplement-sourced catalog entry.
+- `pkg/config/constants_test.go` — `EditionPartition` name handling (`""`, `"open"`, custom edition).
+
+### Docs
+
+- **CHANGELOG v1.0.18 rewrite** (#193) — previous release notes expanded to call out the PAT host-owned A-core flow, exit-code contract change (auth `4`, Discovery/cache/protocol `6`), `dws pat chmod` / `pat browser-policy` entry points, stderr-JSON classifier updates, and host-control metadata injection.
+
+## [1.0.18] - 2026-04-28
+
+Raw DingTalk OpenAPI access lands as a new `dws api` surface for both `api.dingtalk.com` and `oapi.dingtalk.com`, backed by app-level token caching and guarded host allowlists. PAT enters the host-owned **A-core** loop: agent hosts can own authorization UI through `DINGTALK_DWS_AGENTCODE`, parse single-line stderr JSON, call `dws pat chmod`, and replay the original command. Chat helper regressions are fixed, skill references are brought back in line with shipped commands, and the v1.0.17 Mail release notes are backfilled into README / CHANGELOG.
+
+### Breaking
+
+- **PAT exit-code contract** (#142) — PAT authorization interceptions now use exit code `4`; Discovery, cache, and protocol negotiation failures now use exit code `6`. Downstream scripts that previously treated `4` as Discovery must update their handling.
+
+### Added
+
+- **`dws api` raw DingTalk OpenAPI command** (#184) — direct DingTalk OpenAPI calls without writing an MCP wrapper first. Supports `GET` / `POST` / `PUT` / `PATCH` / `DELETE`, JSON `--params` / `--data`, stdin input, dry-run previews, `--jq`, field selection, `--page-all`, `--page-limit`, `--page-delay`, and `--base-url`.
+- **Dual-form OpenAPI routing** (#184) — `api.dingtalk.com` requests use the `x-acs-dingtalk-access-token` header; `oapi.dingtalk.com` requests use the legacy `access_token` query parameter. The raw API client validates the target host before attaching credentials.
+- **App-level token cache for raw API** (#184) — custom-app credentials now fetch app access tokens from the unified OAuth endpoint, cache them while valid, and refresh them before expiry. The same token provider works for new-style and legacy OpenAPI calls.
+- **Host-owned PAT A-core flow** (#142) — when `DINGTALK_DWS_AGENTCODE` is set, PAT hits return `exit=4` plus single-line stderr JSON; the host renders authorization UI, calls `dws pat chmod <scope>...`, and replays the original command.
+- **`dws pat chmod` authorization entry point** (#142) — grants scopes with `--agentCode`, `--grant-type`, and session fallback support; `DINGTALK_DWS_AGENTCODE` can supply the agent code when the flag is omitted.
+- **PAT browser-open policy** (#142) — `dws pat browser-policy --enabled <true|false> [--agentCode <id>]` controls whether the CLI may open a browser, independently from `--format` output mode.
+
+### Changed
+
+- **README raw API guide** (#184) — English and Chinese READMEs now document custom-app prerequisites, api/oapi examples, auto-pagination, dry-run, jq filtering, security properties, and the new Raw API service-table row.
+- **Raw API token retrieval path** (#184) — token lookup now goes through a single app-token interface; stale auth-refresh retry helpers were removed from the raw API path.
+- **PAT stderr JSON classifier** (#142) — recognizes `code`, `errorCode`, and `error_code`, including `PAT_NO_PERMISSION`, risk-tier PAT errors, `PAT_SCOPE_AUTH_REQUIRED`, and `AGENT_CODE_NOT_EXISTS`.
+- **Host-control metadata injection** (#142) — classifier and active-retry paths now share one mutation point for `data.hostControl` and `data.openBrowser`, keeping host-facing JSON shapes aligned.
+- **Open-edition routing signals** (#142) — open edition pins `claw-type: openClaw`; `DINGTALK_AGENT`, `DWS_CHANNEL`, and host-owned PAT detection are kept as independent signals.
+- **Behavior authorization endpoint fallback** (#142) — the PAT runtime can resolve the built-in behavior-authorization MCP endpoint before discovery data is available.
+- **v1.0.17 documentation backfill** (#181) — the previous release notes and README service table now explicitly include the shipped Mail product, update the total to **163 commands across 14 products**, and remove Mail from "Coming soon".
+
+### Fixed
+
+- **CLI auth-denial attribution** — local CLI authorization denials are attributed to the channel before falling back to user-scope classification, avoiding user-scope misclassification for channel-level auth failures.
+- **Opaque authorization URLs** (#182, #142) — PAT authorization links are preserved verbatim, including query/hash/fragment content required by the server.
+- **Polling compatibility** (#182, #142) — device-flow result envelopes and no-`flowId` device-code fallback remain supported, with guarded debug output and envelope priority.
+- **Group chat @-mentions restored** (#180) — `dws chat message send --group ...` again accepts and forwards `--at-users`, `--at-all`, and `--at-mobiles`; those flags are rejected outside group-chat mode so single-chat sends cannot silently drop @-mention intent.
+- **Explicit members-list command restored** (#180) — `dws chat group members list --id <openConversationId>` is reachable after the helper/dynamic merge path changed. `cmdutil.MergeHardcodedLeaves` now honors higher-priority helper groups when a dynamic envelope contributes a leaf at the same path.
+- **Skill reference command names** (#186) — `simple.md` now uses shipped OA command names (`list-pending`, `list-initiated`), removes a non-existent devdoc `search-error` command, and marks `workbench.md` as Draft because workbench commands are not available in the runtime.
+- **Empty grant result handling** (#142) — `dws pat chmod` now returns an explicit error instead of treating `{"Content": null}` as success.
+- **Session-id log safety** (#142) — raw `DWS_SESSION_ID` / `REWIND_SESSION_ID` values are no longer logged when the two env vars disagree.
+
+### Tests
+
+- Added raw API coverage for request validation, api/oapi routing, token management, pagination, response handling, dry-run output, JSON parsing, stdin handling, and command wiring. (#184)
+- Added chat/cmdutil regression tests for group @-mention forwarding, single-chat rejection, `members list`, helper-vs-envelope shape mismatch, and merge-priority behavior. (#180)
+- Added PAT contract coverage for host-owned signal selection, single-line stderr JSON, chmod env fallback and legacy alias fallback, browser policy, direct-runtime PAT endpoint fallback, and retry/poll behavior. (#142)
+- Coverage badge refreshed after the post-v1.0.17 CI runs.
+
+## [1.0.17] - 2026-04-27
+
+New **Mail** product surface (mailbox list, KQL message search, message get, send) brings runtime command count to **163 across 14 products**. Plugin command-tree visibility hardening: stdio plugins shipping CLI overlays no longer wait on subprocess discovery to surface their commands, and overlay-registered plugin products are no longer hidden by edition `VisibleProducts` whitelists. Chat docs clarify that `--title` is required on `dws chat message send`.
+
+### Added
+
+- **`mail` product** (#167) — new top-level service for DingTalk Mail. Four leaf commands across two subgroups:
+  - `dws mail mailbox list` — list mailbox addresses available to the current user (`list_user_mailboxes`)
+  - `dws mail message search` — KQL search across folders / sender / date / attachments / read-state (`search_emails`); supports `--cursor` pagination
+  - `dws mail message get` — fetch full message body + headers + attachments by message ID (`get_email_by_message_id`)
+  - `dws mail message send` — send email to one or more recipients (`send_email`)
+  - Skill reference at `skills/references/products/mail.md` registered in `skills/SKILL.md` master index and intent decision tree
+- **Stdio plugin overlay-first command registration** (#179) — when a stdio plugin's `overlay.json` declares `toolOverrides`, command trees are built from manifest metadata synchronously at startup, no subprocess `Initialize` / `tools/list` handshake required. Previously, slow or failing subprocesses left plugin commands invisible in `dws --help`. Background discovery still runs to refresh the warm cache for richer flag types on subsequent startups.
+
+### Changed
+
+- **`hideNonDirectRuntimeCommands` / `visibleMCPRootCommands` / `visibleUtilityRootCommands`** (#179) — refactored to share a single `resolveVisibleProducts()` helper that **unions** the edition's `VisibleProducts` hook with `DirectRuntimeProductIDs()`, so plugins registered via `AppendDynamicServer` stay visible in `dws --help` even when an edition installs a static product whitelist. Previously the hook fully replaced the dynamic registry, silently hiding plugin commands.
+- **`dws chat message send` documentation clarifies `--title` is required** (#174) — the helper command short text and the chat skill reference now state explicitly that `--title` is mandatory for both group and single-chat sends, matching the runtime validation.
+- **`buildStdioCommands` refactored to share helpers with the overlay-first path** (#179) — overlay parsing (`resolveStdioOverlay`) and tools→DetailTool conversion (`toolsToDetails`) extracted as package-level helpers; the legacy discovery-first stdio path now delegates to them, eliminating duplicated overlay JSON / cache-snapshot logic.
+
+### Fixed
+
+- **Negative-cache poisoning guard for stdio plugin discovery** (#179) — `refreshStdioToolsCache` now skips `SaveTools` entirely when discovery returns an empty tool list (transient failure, subprocess not ready, RPC timeout), so a single bad refresh cannot overwrite a previously-good cache and degrade flag enrichment on the next startup.
+
+### Tests
+
+- 6 new test cases in `internal/app/plugin_stdio_overlay_test.go` and `internal/app/visibility_test.go` cover overlay-first registration without discovery, warm-cache flag enrichment from `InputSchema`, fallback when overlays lack `toolOverrides`, the cache-poisoning guard, and integration cases for plugin visibility under restrictive `VisibleProducts` whitelists.
+- Coverage 49.8% → 52.8%.
+
+## [1.0.16] - 2026-04-24
+
+Discovery service abstraction with schema v3 extensions, open-edition helper-subtree restoration, and a defensive device-flow login reset.
+
+### Added
+
+- **`internal/discovery` service abstraction** (#156) — encapsulates market registry fetch, MCP runtime negotiation (`initialize → tools/list → detail` merge), and multi-level cache fallback. `EnvironmentLoader` now does cache-first startup, with degraded-mode reasons (`unauthenticated` / `market_unreachable` / `runtime_all_failed`) and `UpdatedAt`-based selective re-discovery.
+- **Schema v3 extensions** (#156) — positional parameters with typed coercion, `Example` on `--help`, flag `Default` / `RuntimeDefault` (with `$currentUserId` / `$now` etc.), `BodyWrapper`, `MutuallyExclusive` / `RequireOneOf` flag groups, `OmitWhen`, explicit `Type` override, and detail-schema `default` propagation.
+- **`dws chat message send` destination-flag routing** (#170) — open edition gains a hardcoded helper that dispatches by `--group` (→ `send_message_as_user`) vs `--user` / `--open-dingtalk-id` (→ `send_direct_message_as_user`), mirroring the closed-source overlay so single-chat sends finally work end-to-end.
+
+### Changed
+
+- **`pickCommands` → `cmdutil.MergeHardcodedLeaves`** (#169) — when a top-level product name collides between the dynamic overlay and a helper subtree, helper-only siblings are grafted into the dynamic tree instead of dropped. Restores `dws chat message send-by-bot` / `recall-by-bot` / `send-by-webhook` and `dws chat group members add-bot`, which had silently vanished from the open edition.
+- **`OverridePriority` / `MergeHardcodedLeaves` promoted into `pkg/cmdutil`** (#170) — single source of truth for the merge layer; hardcoded leaves can opt into overriding the dynamic envelope via a strictly higher priority.
+
+### Fixed
+
+- **Device flow defensively resets credentials before login** (#157) — `--device` login now clears stale credential state and re-fetches `clientID` from the MCP server, regardless of what previous login methods (OAuth scan, PAT) left in `app.json`. Fixes the case where a prior OAuth login made `--device` fall back to direct mode and demand `clientSecret`.
+
+## [1.0.15] - 2026-04-23
+
+Compat layer gains **subcommand merging** under shared parents so multiple server entries can contribute into the same `dws <parent> <branch>` subtree without producing duplicate `--help` rows. Ships with a fresh auto-generated command index doc, a README sync to **159 commands across 13 products**, and a wide-ranging flag-naming cleanup that standardises CLI flags across chat, calendar, drive, minutes, contact, and devdoc commands.
+
+### Added
+
+- **`internal/compat` subcommand merging via `attachOrMerge`** — when two or more server entries attach to the same parent (e.g. `parent: "chat"`) and their `cli.command` collides with an existing subcommand in the parent's tree, the new subcommand's children are merged recursively into the existing one instead of creating a duplicate sibling. Leaf-name collisions resolve first-wins. Fixes the "double `group` / `message` rows in `dws chat --help`" symptom when bot capabilities are distributed across `chat.group.members` and `chat.message`.
+- **`docs/command-index.md`** — a single, English, auto-generated listing of every runtime command the `dws` CLI exposes under the pre environment (159 total). Each entry carries a description and a "when to use" column aimed at AI agents. Replaces the earlier `command-index.pre.*` / `command-index.full.*` ad-hoc snapshots.
+
+### Changed
+
+- **README Key Services table** (`README.md` + `README_zh.md`) fully synced to the shipped command surface:
+  - `Chat`: 20 → **23** (bot capabilities merged in; new `list-all` / `list-focused` / `list-unread-conversations` / `conversation-info` exposed)
+  - `Calendar`: 13 → **14**
+  - `AI Tables`: 37 → **41** (chart / dashboard public-share config rows)
+  - `Doc`: 16 → **21** (comment subtree + `file create`)
+  - `Minutes`: 22 → **19** (single-tool `record`, `list query`, `list-by-keyword-range` pruned)
+  - New `Drive` row (6 commands) — promoted out of "Coming soon"
+  - `Workbench` row and standalone `Bot` row removed
+  - Total revised to **159 commands across 13 products**
+- **Quick Start** expanded to 7 examples covering `doc`, `minutes`, `drive` in addition to `contact`, `calendar`, `todo`
+- **Coming soon** trimmed to 5: `mail`, `conference`, `aiapp`, `live`, `wiki`
+- **Reference & Docs** section now leads with a pointer to the new `docs/command-index.md`
+- **Flag naming cleanup** — CLI flags across chat, calendar, drive, minutes, contact, and devdoc have been standardised so the names users type match the product-skill documentation. Notable flags:
+  - `dws contact user search` / `dws contact dept search` / `dws devdoc article search` now take `--query` (previously `--keyword`)
+  - `dws chat message list` / `dws chat message search` / `dws chat message list-mentions` / `dws chat conversation-info` / `dws chat message send` now take `--group` for the target conversation (previously `--id`) and `--open-dingtalk-id` (previously `--open-id`)
+  - `dws chat message list-by-sender` now takes `--sender-user-id` / `--sender-open-dingtalk-id` (previously `--user` / `--open-id`)
+  - `dws chat message list-topic-replies` now takes `--group` / `--topic-id` / `--limit` / `--time` (previously `--id` / `--topic` / `--size` / `--start`)
+  - `dws chat search-common` now takes `--match-mode` (previously `--mode`)
+  - `dws drive list` now takes `--max` / `--thumbnail` (previously `--max-results` / `--with-thumbnail`)
+  - `dws calendar event suggest` now takes `--users` / `--duration` / `--timezone` (previously `--attendee-user-ids` / `--duration-minutes` / `--time-zone`)
+  - `dws minutes list mine` / `dws minutes list shared` now take `--max` (previously `--max-results`) and gain `--query` / `--start` / `--end`
+  - `dws minutes list all` no longer exposes the legacy `--__scope__` internal alias
+- **Flag coverage additions** — `dws calendar event create` / `update` gain `--attendees`, `--open-dingtalk-ids`, `--timezone`; `dws chat message send` gains file-message flags (`--dentry-id`, `--file-name`, `--file-size`, `--file-type`, `--media-id`, `--msg-type`, `--space-id`) plus `--open-dingtalk-id` / `--user`; `dws chat message list` gains `--open-dingtalk-id` / `--user`; `dws aitable table delete` gains `--reason`; `dws calendar participant add` gains `--optional`; `dws todo task create` gains `--recurrence`.
+
+### Tests
+
+- 3 new unit tests in `internal/compat/dynamic_commands_test.go`:
+  - `TestBuildDynamicCommands_ParentMergeSameName` — two servers with identical `command` + `parent` collapse into a single merged subcommand
+  - `TestBuildDynamicCommands_ParentMergeRecursive` — recursive merge through nested groups (e.g. `chat.group.members`)
+  - `TestBuildDynamicCommands_ParentMergeLeafCollision` — identical leaf paths resolve first-wins without producing duplicates
+
+## [1.0.14] - 2026-04-22
+
+Docs-only re-tag of v1.0.13. The single commit (#153) backfills the v1.0.13 release notes after the binary was already published; no functional or CLI surface change.
+
+## [1.0.13] - 2026-04-22
+
+IM / Messaging capability expansion: the `chat` (aka `im`) product surface grows from "group + bot messaging" into a full conversational layer — user-identity messaging, message reading & search, personal messages, topic replies, mentions, focused contacts, unread/top/common conversations, org-wide group creation, and first-class bot lifecycle.
+
+### Added
+
+- **`dws im` alias** — `dws im` is now registered as an alias of `dws chat` for intent clarity
+- **User-identity messaging** (`chat message send`) — send group or 1-on-1 messages as the current user
+  - Recipient selection is mutually exclusive: `--group <openConversationId>` / `--user <userId>` / `--open-dingtalk-id <openDingTalkId>`
+  - Markdown text via `--text` (or positional arg), optional `--title`
+  - Group-only: `--at-all` to @everyone, `--at-users` for per-member @mentions
+  - Image messages via `--media-id` (obtained from `dt_media_upload`)
+- **Personal messages** (`chat message send-personal`) — sensitive personal-channel send (⚠️ destructive/dangerous op, requires confirmation)
+- **Conversation read paths**:
+  - `chat message list` — pull group / 1-on-1 conversation messages
+  - `chat message list-all` — pull all conversations for the current user in a time range
+  - `chat message list-topic-replies` — pull group topic reply threads
+  - `chat message list-by-sender` — messages by a specific sender
+  - `chat message list-mentions` — messages where the current user was @-mentioned
+  - `chat message list-focused` — messages from focused / starred contacts
+  - `chat message list-unread-conversations` — unread conversation list
+  - `chat message search` — keyword search across conversations
+  - `chat message info` — conversation metadata
+  - `chat list-top-conversations` — pinned conversation list
+- **Group creation & discovery**:
+  - `chat group create-org` — create an organization-wide group
+  - `chat search-common` — search groups shared with a nickname list (`--nicks`, `--match-mode AND|OR`, cursor-based pagination)
+- **Bot lifecycle**:
+  - `chat bot create` — create an enterprise bot
+  - `chat bot search-groups` — search the groups a bot is present in
+
+### Changed
+
+- **`chat` skill reference** (`skills/references/products/chat.md`, #148) restructured into three sub-groups — `group` (9) / `message` (15) / `bot` (3) — with refreshed intent-routing table, workflow examples, and context-passing rules aligned with `dws-service-endpoints.json` (16 new group-chat tool overrides + 2 new bot tool overrides)
+- **README Key Services** sync:
+  - `Chat` row: 10 → 20 commands; subcommand tags expanded to `message` `group` `search` `list-top-conversations`
+  - `Bot` row: 6 → 7 commands; subcommand tags expanded with `create` `search-groups`
+  - Total raised to **152 commands across 14 products**
+
+## [1.0.12] - 2026-04-21
+
+Product-surface expansion: first-class `doc` (DingTalk Docs) and `minutes` (AI Minutes) skill references, refreshed `aitable` guide aligned with the shipped binary (including dashboard / chart / export), and a README sync that brings the full command catalog to **141 commands across 14 products**.
+
+### Added
+
+- **`doc` skill reference** (`skills/references/products/doc.md`) — 16-command coverage of DingTalk Docs:
+  - Discovery: `search`, `list`, `info`, `read`
+  - Authoring: `create`, `update`, `folder create`
+  - Files: `upload`, `download`
+  - Block-level editing: block `query`, `insert`, `update`, `delete`
+  - Comments: `comment list`, `create`, `reply`
+  - URL → `doc_id` extraction rules and nodeId dual-format notes
+- **`minutes` skill reference** (`skills/references/products/minutes.md`) — coverage of AI Minutes:
+  - Lists: personal / shared-with-me / all-accessible
+  - Content: basic info, AI summary, keywords, transcription, extracted todos, batch detail
+  - Editing: title update
+  - Recording control: start, pause, resume, stop
+- **SKILL.md routing**:
+  - Product overview table rows for `doc` and `minutes`
+  - Intent decision tree routes — `钉钉文档/云文档/知识库/块级编辑/文档评论` → `doc`; `听记/AI听记/会议纪要/转写/摘要/思维导图/发言人/热词` → `minutes`
+  - Danger-op table entries: `doc delete`, `doc block delete`
+  - `aitable` description completed with the `附件` (attachment) group
+- **`aitable` skill enhancements**:
+  - `field create` single-field mode (`--name` / `--type` / `--config`) with examples
+  - `base get` URL → `baseId` quick-tip
+  - Dedicated "URL → baseId 提取" chapter
+  - "`--filters` 筛选语法排错与使用规范" chapter
+  - "相关产品" cross-link section pointing to `doc`
+  - **"复杂操作" chapter** (#141) — dashboard / chart workflow (with two-call sequencing and `chart share get` vs `dashboard share get` error semantics) and two-stage `export data` polling (`scope=all/table/view` parameter constraints)
+- **README Key Services sync** (#140):
+  - New rows: `doc` (16 commands), `minutes` (22 commands — adds `hot-word`, `mind-graph`, `replace-text`, `speaker`, `upload` subgroups)
+  - `aitable` expanded from 20 → 37 commands; surfaces `chart`, `dashboard`, `export`, `import`, `view` subgroups
+  - Total command count updated from **86 → 141 across 14 products**
+  - "Coming soon" list drops `doc` and `minutes`
+
+### Changed
+
+- `aitable record query` docs rename `--keyword` → `--query` to match the shipped binary
+- `aitable record query` docs clarify `--sort` direction semantics (avoids misuse of `order`)
+- `aitable base list` guidance strengthened — "only for recent browsing; use `base search` for lookups"; intent decision prioritizes `base search` for base discovery
+
+## [1.0.11] - 2026-04-20
+
+Plugin subsystem hardening: faster cold startup, cleaner lifecycle, stricter isolation, and polished UX for PAT / i18n / error routing.
+
+### Added
+
+- `feat: supports claw-like products` — overlay path for Claw-style embedded editions
+- `feat(plugin): inject user identity (UserID, CorpID) into stdio plugin subprocesses`
+- `feat(auth): improve login UX for terminal auth denial cases` — clearer messaging + retry affordance
+- `feat: PAT scope error visualization and auto-retry with authorization polling` (#113)
+  - Human-readable error output (lark-cli style) with type/message/hint/authorization command
+  - JSON payload also available via `--format json`
+  - Auto-retry once the user completes scope authorization
+
+### Changed
+
+- `perf(plugin): serve plugin MCP tool list from disk cache on startup` — hot path skips Initialize+ListTools when snapshot exists
+- `perf(plugin): parallelize all plugin discovery and tighten cold timeouts` — HTTP cold budget 4s → 700ms (auth) / 500ms (plain); stdio and HTTP fan out concurrently
+- `perf(plugin): share cache.Store across discovery` — single `*cache.Store` above the fan-out instead of per-goroutine instances
+- `refactor(plugin): remove default/managed plugin privileged mechanism` (#124) — third-party plugins install on an equal footing via `dws plugin install`
+- `refactor(plugin): purge removed plugin settings instead of merely disabling` — `RemovePlugin` now deletes `EnabledPlugins` and `PluginConfigs` entries
+
+### Fixed
+
+- `fix(transport): cap plugin MCP startup at ~4s when endpoints are unreachable` (#119) — eliminates the 10s `dws --help` stall caused by compounding transport timeouts
+- `fix(plugin): stop stdio child processes on exit and before removal` — no more orphaned plugin subprocesses
+- `fix(pat): avoid shared PAT command state in root registration` (#129)
+- `fix: -f json 模式下错误 JSON 从 stdout 改为输出到 stderr` (#133) — restores CI stderr-based failure assertions
+- `fix(cli): localize plugin/help command strings via i18n` (#118, #134) — zh locale now shows consistent Chinese `--help`; wraps plugin module, help command, and OAuth client-id/secret flag descriptions
+- `chore: remove workspace and bundled artifacts` (#127) — clean local-only repository leftovers
+
+## [1.0.9] - 2026-04-16
+
+Plugin system launch + execution-pipeline overhaul. This is the largest release since 1.0.0: third-party MCP servers become first-class commands, the command pipeline grows to five stages, and the edition overlay gains the hooks needed for embedded hosts.
+
+### Added
+
+#### Plugin system (new)
+
+- `plugin` command family: `install`, `list`, `info`, `enable`, `disable`, `remove`, `create`, `dev`, `config set/get/list/unset`
+- Plugin manifest parsing/validation, managed/user directory-based identity
+- MCP server conversion and injection into the dynamic routing registry
+- Pipeline hook adapter for shell-based hooks
+- Stdio transport: subprocess lifecycle, `DWS_PLUGIN_ROOT` / `DWS_PLUGIN_DATA` variable expansion
+- Stdio server tools automatically registered as CLI subcommands (e.g. `dws hello greet --name Peter`)
+- Streamable-HTTP MCP tool discovery via `registerHTTPServer`
+- Updater: managed plugin update check on CLI startup (10 s timeout, best-effort)
+- `dws plugin create` scaffold (plugin.json, SKILL.md, hooks.json); `dws plugin dev` source-dir registration without copy
+- `SyncSkills` — copies plugin skills to agent directories on startup
+- **Auth Token Registry**: per-server HTTP headers declared in `plugin.json` for third-party MCP servers (e.g. Alibaba Cloud Bailian) independent from DingTalk OAuth
+- **Persistent plugin config** (`dws plugin config ...`): values persisted to `~/.dws/settings.json`, auto-injected as env vars; `${KEY}` in `plugin.json` resolves without manual `export`
+- **Build lifecycle**: `build` field compiles stdio servers to native binaries at install time
+- **Command-name conflict protection**: reserved built-in names (`auth`, `plugin`, `cache`, …) and plugin-vs-plugin duplicate detection
+- Parallel service discovery (`sync.WaitGroup`) — startup reduced from sequential `N*10s` to parallel `max(10s)`
+
+#### Core commands & diagnostics
+
+- `dws doctor` — one-stop environment/auth/network diagnostics
+- `dws config list` — centralized view of scattered configuration
+- Structured perf tracing (upgraded from debug tool to diagnostics output)
+- `feat(skill): restore find/get for legacy skill market API` — `skill find`, `skill get`; `skill add` still uses aihub download
+
+#### Edition / overlay hooks
+
+- `edition.Hooks.SaveToken` / `LoadToken` / `DeleteToken` — delegate token persistence with keychain fallback
+- `edition.Hooks.AuthClientID` / `AuthClientFromMCP` — overlay can override the OAuth client ID and route auth through MCP endpoints
+- `edition.Hooks.AfterPersistentPreRun` — wire non-MCP clients (e.g. A2A gateway) after root setup
+- `edition.Hooks.ClassifyToolResult` — custom MCP result classification before the default business-error detection
+- Token marker file (`token.json`) for embedded hosts to detect auth state without keychain access
+- `pkg/runtimetoken.ResolveAccessToken` mirroring MCP auth resolution; MCP identity headers exported via `pkg/cli` for auxiliary HTTP transports
+- `ExitCoder` interface — edition-specific errors carry custom exit codes
+- `RawStderrError` interface — errors that bypass CLI formatting and emit raw stderr (for desktop runtimes)
+
+### Changed
+
+- **Command execution pipeline: 3 → 5 stages** (`Register → PreParse → PostParse → PreRequest → PostResponse`)
+- `feat(schema): return structured degraded errors instead of silent empty catalog` — new `CatalogDegraded` error with reasons `unauthenticated` / `market_unreachable` / `runtime_all_failed`; auth pre-check short-circuits doomed MCP connections
+- `refactor(auth): unify auxiliary token resolution with MCP cached path` — shared `resolveAccessTokenFromDir`; overlays reuse the process-level token cache
+- `feat(plugin): improve CLI overlay resolution and plugin install robustness`
+  - `plugin.json` `cli` field now accepts a file path (e.g. `"cli": "overlay.json"`) in addition to inline JSON
+  - `description` field on `CLIToolOverride` for static fallback when MCP `tools/list` is unavailable
+  - Windows install uses `cmd /C` instead of `sh -c` for build commands
+
+### Fixed
+
+- `fix(plugin): harden plugin system security boundaries`
+  - Reject `file://` / local paths in git URLs; allow only `https` / `ssh`
+  - Reject symlink entries during ZIP extraction (path-traversal defense)
+  - `build.output` must be a relative path within the plugin directory
+  - Reject absolute paths in stdio command declarations
+  - Block dangerous env var names (`PATH`, `LD_PRELOAD`, …) from plugin config injection
+- `fix(plugin): schema flag params, HTTP tool discovery, and integration tests`
+- `fix(plugin): skip min version check in dev mode`
+
+## [1.0.8] - 2026-04-07
+
+AITable command surface expansion, installer alignment with npm conventions, and execution-timeout hardening.
+
+### Added
+
+- **AITable static helper commands** (20 commands in total) replacing dynamic routing:
+  - `base`: `list`, `search`, `get`, `create`, `update`
+  - `table`: `get`, `create`, `update`
+  - `field`: `get`, `create`, `update`
+  - `record`: `query`, `create`, `update`
+  - `template`: `search`
+  - `attachment`: `upload`
+- `feat(install): align skill dirs with npm and add OpenClaw` — skill install paths follow npm conventions; OpenClaw added to supported agents
+- Label rendering optimization for AITable records (`to #73551688`)
+- README: npm install method documented
+- README: note that `dws upgrade` requires v1.0.7+
+
+### Changed
+
+- `perf: optimize command timeout handling, instrumentation, and diagnostics`
+
+## [1.0.7] - 2026-04-02
+
+Self-upgrade, edition overlay foundation, and fail-closed auth enforcement.
+
+### Added
+
+- **`dws upgrade`** — self-upgrade via GitHub Releases; atomic replace; cross-platform (macOS/Linux/Windows)
+- `feat: edition layer for Wukong overlay` — build-time edition hook lets downstream overlays customize auth UX, config dir, static server list, visible products, and extra root commands
+  - `pkg/edition` defaults + `pkg/editiontest` contract tests
+  - `Makefile` target `edition-test`; CI job `edition-tests`
+  - Static server injection skips market discovery when configured
+  - Deduplicates top-level commands so overlay wins
+  - `hideNonDirectRuntimeCommands` respects edition `VisibleProducts`
+  - Gated `auth login` subcommand + hints for embedded editions
+  - Optional token auto-purge; edition `ConfigDir` override
+- `dws version` — human-readable multi-line output plus JSON with edition, architecture, build, commit
+- Tag reporting for case suites (`to #73551688`)
+- `feat(auth): unify MCP retry constant and add retry to remaining endpoints`
+
+### Changed
+
+- `style(auth): redesign OAuth authorization pages UI`
+
+### Fixed
+
+- `fix(auth): switch CLI auth check from fail-open to fail-closed`
+  - When `/cli/cliAuthEnabled` is unreachable (network error/timeout/5xx), OAuth callback now routes to the permission request page instead of silently marking "enabled"
+  - Device Flow blocks login and asks the user to verify network connectivity
+  - `CheckCLIAuthEnabled` retries with backoff (3 attempts, 0s/1s/2s) to tolerate transient issues
+
+## [1.0.6] - 2026-04-01
+
+Error diagnostics overhaul, destructive-command confirmation, and credential auto-persistence.
+
+### Added
+
+- **Interactive confirmation for destructive dynamic commands** — prompts before delete/remove operations unless `--yes` is set
+- **Enhanced error diagnostics**
+  - `ServerDiagnostics` struct extracts `trace_id`, `server_error_code`, `technical_detail`, `server_retryable` from MCP responses
+  - Pulls diagnostics from JSON-RPC `error.data`, tool call result content, and HTTP headers (`X-Trace-Id`, `X-Request-Id`, `x-dingtalk-trace-id`)
+  - Three verbosity levels for `PrintHuman`: Normal (trace ID + server code), Verbose (+ technical detail), Debug (+ RPC code / operation / reason)
+  - Local logging now includes sanitized request body, response body on error, retry attempts, and classification events
+  - `TruncateBody` / `SanitizeArguments` / `RedactHeaders` helpers with sensitive-key substring detection
+- **Auth credential persistence**
+  - `feat(auth): enhance device flow with CLI auth check and admin guidance`
+  - `feat(auth): persist OAuth credentials for reliable token refresh`
+  - `feat(auth): persist client credentials and optimize keychain access` — auto-persist `--client-id` / `--client-secret`; keychain credential cache to avoid repeated reads; enhanced logout cleans `app.json` + keychain secrets + `token.json`
+- `add report helper with flexible date parsing and defaults`
+- `feat: to #73551688 支持消息通知`
+- README: Official App mode (recommended, direct login without creating an app) + Custom App mode; admin guide for enabling CLI access
+
+### Changed
+
+- Getting Started simplified with inline login commands; whitelist references removed from the IMPORTANT banner
+- Version bump documentation updated to v1.0.5 internal; co-creation group QR code refreshed
+
+### Fixed
+
+- `fix: resolve verbosity flag lookup, FileLogger lazy binding, and business error logging`
+  - `resolveVerbosity` uses `cmd.Flags()` instead of `PersistentFlags()` so subcommands inherit `--verbose` / `--debug`
+  - `FileLogger` lazy-binds in `executeInvocation` (after `configureLogLevel` init)
+  - Business errors (HTTP 200 + `success=false`) now written to the file logger for offline diagnosis
+- OAuth callback race condition (write response before sending code)
+- `import path for errors package in skill_command.go`
+
+## [1.0.4] - 2026-03-30
+
+Token-refresh reliability and onboarding clarity.
+
+### Added
+
+- `feat(auth): persist client credentials for token refresh` — `--client-id` / `--client-secret` are stored for automatic refresh after expiration; client secret lives in the system Keychain with a file reference
+- README onboarding flow rewrite with step-by-step first-time setup and more realistic examples
+- Agent skill reference polish: clearer examples, updated intent routing patterns, expanded `simple.md` onboarding, cross-skill reference fixes
+
+## [1.0.3] - 2026-03-29
+
+Filtering power, schema rendering, and a native `todo` command family.
+
+### Added
+
+- **Nested / array-indexed output filtering**
+  - `--fields` now accepts dot-notation (e.g. `--fields response.content`) and array index access (e.g. `response.items[0]`)
+  - New field-path parser with recursive extraction logic
+- **`schema` command enhancements**
+  - Table format output for human consumption
+  - Product-level endpoint loading in the CLI loader
+  - Schema-text rendering wired into the runner output pipeline
+- **`todo` task helper family** — static `create` / `update` / `done` / `get` / `delete` with `preferLegacyLeaf` replacing dynamic commands
+  - MCP tool alignment: `create_personal_todo`, `update_todo_task`, `update_todo_done_status`, `query_todo_detail`, `delete_todo`
+  - ISO-8601 due-time parsing
+  - Hidden title aliases and delete confirmation
+  - Priority field on `todo` helper
+  - Expanded zh / en i18n coverage (fixes `en.json` spacing/wording issues)
+- README restructured with collapsible feature sections
+
 ## [1.0.2] - 2026-03-29
 
 Deep workspace tooling upgrade: pipeline-based input correction, output filtering, enhanced stdin handling, and multi-endpoint routing.

+| **mono** (stable, default) | One `dws` skill covering all products | Cross-product workflows; single entry point |
+| **multi** 🧪 **EXPERIMENTAL** | 18 per-product skills (`dingtalk-aitable`, `dingtalk-calendar`, `dingtalk-chat`, ...) | Single-product tasks; smaller context per call |
+
+> 🧪 **`multi` is currently EXPERIMENTAL / preview.** 18 product-scoped skills all pass the dispatch verifier, but interface, naming and cross-skill references may change in future releases. For production / shared environments, prefer `mono`. File issues if you hit problems.
+
+How to pick:
+
+- **Quick install** (one-liner above): non-interactive, installs `mono`.
+- **TTY install** (download then run): `curl -O .../install.sh && bash install.sh` — prompts `1) mono  2) multi` (default 1).
+- **Override via env**: `DWS_SKILL_MODE=multi curl -fsSL ... | sh`.
+- **Switch later**: `dws skill setup --mode multi` (or `--mode mono`) — re-run any time.

+<summary><strong>Raw API Access</strong> — call any DingTalk OpenAPI directly</summary>
+
+`dws api` lets you call any DingTalk OpenAPI without an SDK. Tokens are automatically acquired and refreshed.
+
+> **Prerequisite**: Must login with your own app credentials (see [Custom App mode](#getting-started)). Encrypted tokens from MCP default-credential login are not supported for raw API calls.

+| Automatic token management | App-level accessToken is fetched on first call, cached while valid, auto-refreshed on expiry |
+| Domain allowlist | Only `api.dingtalk.com` and `oapi.dingtalk.com` permitted — prevents token leakage |
+| Auto-pagination | `--page-all` iterates all pages. `--page-limit` caps the maximum (default 10, set to 0 for unlimited, hard cap at 500 to prevent infinite loops) |

 ### Agent Skills
 
-仓库内置完整的 Agent Skill 体系（`skills/`），安装后 Claude Code / Cursor 等 AI 工具可通过自然语言直接操作钉钉：
+仓库内置完整的 Agent Skill 体系（`skills/` 目录），目前重组为两套布局：
+
+- `skills/mono/` — 单 skill 布局（一个 `SKILL.md` + `references/products/`），默认推荐。
+- `skills/multi/` — 每个产品一个独立 skill（`dingtalk-aitable/` / `dingtalk-calendar/` / `dingtalk-chat/` ... 共 18 个），每个 skill 自带 `SKILL.md`。🧪 **试验版 / Preview — 各 multi `SKILL.md` 头部有详细注意事项。**
+
+安装之后，Claude Code / Cursor 等 AI 工具就能通过自然语言直接操作钉钉：
 
 ```bash
-# 安装 skills 到当前项目
+# 安装 skills 到当前项目（默认 mono）
 curl -fsSL https://raw.githubusercontent.com/DingTalk-Real-AI/dingtalk-workspace-cli/main/scripts/install-skills.sh | sh
 ```
 
 > `install.sh` 安装到 `$HOME/.agents/skills/dws`（全局）；`install-skills.sh` 安装到 `./.agents/skills/dws`（当前项目）。
 
-**包含内容：**
+**用 `dws skill setup` 切换或重装：**
+
+```bash
+# 交互式：提示选模式 + 目标 Agent
+dws skill setup
+
+# 把 mono skill 铺到所有检测到的 Agent home（claude / cursor / codex / opencode / qoder）
+dws skill setup --mode mono --target all --yes
+
+# 只装到某一个 Agent home
+dws skill setup --mode multi --target cursor --yes
+
+# 指定本地源目录（比如 fork 或正在改的版本）
+DWS_SKILL_SOURCE=/path/to/skills dws skill setup --mode multi
+```

 ## 功能特性
 
+<details>
+<summary><strong>Raw API 调用</strong> — 直接调用钉钉 OpenAPI</summary>
+
+`dws api` 让你直接调用任意钉钉 OpenAPI，无需 SDK，Token 自动获取和刷新。
+
+> **前置条件**：必须使用自有应用凭证登录（见[自建应用模式](#开始使用)）。通过 MCP 默认凭证登录 不支持 raw API 调用。
+
+```bash
+# 登录（仅首次）
+dws auth login --client-id <APP_KEY> --client-secret <APP_SECRET>
+
+# === api.dingtalk.com ===
+
+# 获取企业所有应用列表
+dws api GET /v1.0/microApp/allApps
+
+# 搜索用户 (POST + JSON body)
+dws api POST /v1.0/contact/users/search \
+  --data '{"queryWord":"张三","offset":0,"size":10}'
+
+# === oapi.dingtalk.com ===
+
+# 获取用户详情（使用 --base-url 指定域名）
+dws api POST /topapi/v2/user/get \
+  --base-url https://oapi.dingtalk.com \
+  --data '{"userid":"<USER_ID>"}'
+
+# 也可以直接使用完整 URL
+dws api POST https://oapi.dingtalk.com/topapi/v2/user/get \
+  --data '{"userid":"<USER_ID>"}'
+
+# === 通用功能 ===
+dws api GET /v1.0/microApp/allApps --page-all   # 自动翻页
+dws api GET /v1.0/microApp/allApps --dry-run     # 预览请求
+dws api GET /v1.0/microApp/allApps --jq '.agentId'  # jq 过滤
+```
+
+| 特性 | 说明 |
+|------|------|
+| 双形态自动识别 | 根据 URL 自动选择 api.dingtalk.com（Header 认证）或 oapi.dingtalk.com（Query 参数认证） |
+| Token 自动管理 | 首次调用自动获取应用级 accessToken，有效期内缓存，过期自动刷新 |
+| 域名白名单 | 仅允许 `api.dingtalk.com` 和 `oapi.dingtalk.com`，防止 Token 泄露 |
+| 自动分页 | `--page-all` 自动遍历所有分页。`--page-limit` 控制翻页上限（默认 10，设为 0 不限制，硬上限 500 防止死循环） |

+**41 commands**
+
+| Command | Description | When to use |
+|---|---|---|
+| `dws aitable attachment upload` | Request an upload ticket for attaching a file to an AI table attachment-type field. Returns an upload URL and token the caller uses to stream the file. | When the agent needs to attach binary assets (images, PDFs, etc.) to records before creating or updating an attachment field value. |
+| `dws aitable base create` | Create a new AI table (Base) under the current user's workspace. Returns the newly-created Base ID. | When an agent needs to provision a fresh Base before populating datasheets, fields, and records. |
+| `dws aitable base delete` | Permanently delete an existing AI table (Base) by ID, removing all its datasheets, views, and records. | When the agent is cleaning up a Base that is no longer needed or was created for a one-off task. |
+| `dws aitable base get` | Retrieve metadata for a single AI table (Base), including name, owner, and structural summary. | When the agent needs to inspect a specific Base before performing further operations on it. |
+| `dws aitable base list` | List AI tables (Bases) accessible to the current user, paginated. | When the agent needs to enumerate the user's Bases to pick one by name or index. |
+| `dws aitable base search` | Search AI tables (Bases) the current user can access by keyword against the Base name. | When the agent knows a partial Base name and needs to resolve it to a Base ID. |
+| `dws aitable base update` | Update mutable properties of an AI table (Base), such as its name or icon. | When the agent needs to rename or rebrand an existing Base without touching its data. |
+| `dws aitable chart create` | Create a new chart inside a Base, bound to a datasheet and view with a given configuration. | When the agent is building analytics on top of a datasheet and needs to materialize a chart visualization. |
+| `dws aitable chart delete` | Delete a chart from a Base by chart ID. | When the agent needs to remove an obsolete or mistakenly-created chart. |
+| `dws aitable chart get` | Retrieve a chart's full configuration and metadata. | When the agent needs to inspect an existing chart to clone it or adjust its configuration. |
+| `dws aitable chart share get` | Retrieve the current public-sharing configuration of a chart, including share link and permissions. | When the agent needs to check whether a chart is already shared externally before issuing a link. |
+| `dws aitable chart share update` | Enable, disable, or update the public-sharing configuration of a chart. | When the agent needs to generate or revoke an external share link for a chart. |
+| `dws aitable chart update` | Update an existing chart's configuration (type, dimensions, metrics, style). | When the agent iterates on a chart's visualization after reviewing the initial result. |
+| `dws aitable chart widgets-example` | Return a reference JSON example of chart widget configuration accepted by chart create/update. | When the agent needs a schema template before composing chart configuration payloads. |
+| `dws aitable dashboard config-example` | Return a reference JSON example of dashboard configuration accepted by dashboard create/update. | When the agent needs a schema template before composing dashboard layout payloads. |
+| `dws aitable dashboard create` | Create a new dashboard inside a Base with a layout of chart widgets. | When the agent wants to group multiple charts into a single dashboard view for a report or overview page. |
+| `dws aitable dashboard delete` | Delete a dashboard from a Base by dashboard ID. | When the agent is removing an outdated dashboard. |
+| `dws aitable dashboard get` | Retrieve a dashboard's layout, widget list, and metadata. | When the agent needs to inspect a dashboard before updating it or cloning it. |
+| `dws aitable dashboard share get` | Retrieve the current public-sharing configuration of a dashboard. | When the agent needs to verify whether a dashboard has an active external share link. |
+| `dws aitable dashboard share update` | Enable, disable, or update the public-sharing configuration of a dashboard. | When the agent needs to generate or revoke an external share link for a dashboard. |
+| `dws aitable dashboard update` | Update an existing dashboard's layout, widgets, or metadata. | When the agent adds, removes, or rearranges charts on an existing dashboard. |
+| `dws aitable export data` | Export data from a datasheet (optionally scoped to a view) to a downloadable file such as Excel or CSV. | When the agent needs to hand off Base data to an external system or deliver it as an attachment. |
+| `dws aitable field create` | Create one or more fields in a datasheet with specified types and options. | When the agent is extending a datasheet's schema to capture new attributes. |
+| `dws aitable field delete` | Delete a field from a datasheet by field ID; all values in that column are removed. | When the agent is cleaning up unused or deprecated columns in a datasheet. |
+| `dws aitable field get` | Retrieve field definitions for a datasheet, including type, options, and order. | When the agent needs the field schema before constructing record payloads or queries. |
+| `dws aitable field update` | Update a field's name, type, or options in a datasheet. | When the agent needs to rename a column or change its type/options without recreating it. |

+|------|------|
+| `name` / `cli_name` / `canonical_path` | MCP RPC 名 / CLI 叶子名 / `product.rpc_name` |
+| `group` | CLI 父级 group 路径（dot-separated） |
+| `title` / `description` | 工具名/说明（overlay 优先） |
+| `parameters` / `required` | MCP 输入 JSON Schema 的 properties / required |
+| `output_schema` | MCP 输出 Schema（上游下发时才有） |
+| `sensitive` | 敏感写操作，需 `--yes` 确认 |
+| `auth` | DingTalk 授权元数据，包括 `requiredScopes` / `requiredPermissions` / `recommendedScopes` / `grantProductCodes` / `riskAction` / `confirmationRequired` |
+| `annotations.destructive_hint` | 对齐 MCP 2025+ annotations，目前从 `sensitive` 映射 |
+| `flag_overlay[param]` | CLI 层对 MCP 参数的改写：`alias` / `transform` / `transform_args` / `env_default` / `default` / `hidden` |
+
+**调试 `--flag` 行为的第一站**是 `flag_overlay` —— 比如 `--users 0232...` 能不能直接用，看 `receiverUserIdList.transform == "csv_to_array"` 即可判断。

+dws schema calendar.create_event --jq '.tool.auth'                # 只看授权元数据
+dws schema --jq '.products[] | {id, count: (.tools|length)}'      # 各产品工具数
+dws schema aitable.delete_base --jq '.tool.annotations'           # 敏感操作提示

+// mail_hooks.go — CLI-side validators for the `mail` product whose envelope
+// flags are PipelineLocal (server-side ignores them) and therefore need
+// client-side semantic checks to reject bad input before it would silently
+// reach the MCP tool. Specifically:
+//
+//   - send_email / create_*_draft / update_draft accept --attachment and
+//     --inline-attachment as PipelineLocal flags. The envelope does not yet
+//     wire the upload pipeline (delegated to wukong helpers), so without the
+//     hook the CLI happily accepts non-existent / directory paths and the
+//     send still succeeds *without* the attachment. The auto-tests
+//     (mail/test_02_mail_attachment.py) flag this as a regression.
+//
+//   - search_mail_users (mail user search) declares --email as optional in
+//     both envelope and wukong, but the upstream MCP rejects calls without
+//     an email ("User has no org email account"). The auto-test
+//     (mail/test_05_mail_user_search.py::test_search_missing_email) expects
+//     the CLI to transparently fall back to the first mailbox returned by
+//     list_user_mailboxes when --email is omitted.
+//
+// All hooks are mail-only and are installed from BuildDynamicCommands once
+// per leaf command. The wrap preserves any existing PreRunE (e.g.
+// validateRequireTogether) by chaining.
