# Architecture
|
|
|
|
`dws` is a Go CLI with a versioned, static command surface for DingTalk MCP capabilities. Cobra help serves humans; the embedded Command Catalog serves AI agents.
|
|
|
|
## High-Level Flow
|
|
|
|
1. `cmd` is the CLI entrypoint, invoking `internal/app` to build the root Cobra command tree.
|
|
2. `internal/app` wires static utility commands (`auth`, `audit`, `schema`, `completion`), product helpers, and versioned plugin descriptors.
|
|
3. `internal/helpers` contains the main command handlers for all product surfaces (`dev`, `chat`, `calendar`, `contact`, `aitable`, etc.).
|
|
4. `internal/executor` and `internal/transport` execute MCP JSON-RPC calls; `internal/output` formats responses.
|
|
5. `internal/auth` manages login state, PAT tokens, and agent-code detection.
|
|
6. Schema generation starts from the reviewed `CommandRegistry`, binds each identity to the exact current Cobra leaf, and then resolves typed constraints, sanitized MCP snapshots, Agent hints, and Skills into one `SchemaRegistry`. Startup and Schema queries do not call MCP `tools/list`.
|
|
7. The embedded Catalog is a downstream release artifact and never backfills identity or participates in regeneration. Stable flag-to-interface property bindings come from the reviewed, content-addressed v3 manifest in `schema_parameter_bindings.json`; its exact active tuples, corrections, removals, and mapping exclusions are validated against the final bound `SchemaRegistry`. CLI `required` and constraints come from the resolved typed contract, while MCP `required` remains interface-only metadata.
|
|
8. Agent selection results are fixed in versioned review inputs. Every public tool has explicit use/avoid/example and interface disposition metadata; Skill references that are not current leaves require an explicit alias/group/stale/out-of-surface review instead of fuzzy runtime matching.
