MCP Tool Docs Stinger

mcp-tool-docs-stinger

Procedural arsenal for mcp-tool-docs-worker-bee, the Hive's tool/API/CLI documentation specialist. This stinger encodes how to document any tool, API, and CLI surface honestly: schema-selected tools (MCP tools first and foremost - name, purpose, input schema, output shape, side effects, annotations, examples), the TypeScript public API rendered with a generator (TypeDoc, and API Extractor where a reviewable public-API contract is needed), a CLI's command surface, doc-to-code sync discipline, and changelog discipline tied to a released artifact's real version.

Hivemind (@deeplake/hivemind) - the MCP tools exposed by src/mcp/server.ts plus the OpenClaw goal/KPI contracts, its TypeScript public API, the hivemind CLI, and its sync-versions-driven changelog - remains fully covered throughout as a worked example. The guides teach the general practice first and point to the Hivemind case for a real, end-to-end illustration.

When this stinger applies

Load this stinger when mcp-tool-docs-worker-bee is invoked. Typical triggers:

• "Document these MCP tools."
• "Is the description on this tool honest? Does it match the code?"
• "Write the input schema and output shape for this tool."
• "Generate the TypeScript API reference."
• "Document this CLI's command surface."
• "These docs drifted from the code - re-sync them."
• "Write a changelog entry for this release."
• "Audit the tool/API/CLI docs."
• "Document the Hivemind MCP tools / the hivemind CLI / Hivemind's TypeDoc setup." (the worked-example case)

Do NOT load it for:

• MCP protocol, transport, or handshake internals (route to mcp-protocol-worker-bee).
• Prose-quality review or ghostwriting - Diataxis mode, inverted-pyramid structure, voice/tone, "is this well-written" (route to technical-writing-craft-worker-bee). This Bee transcribes facts from source honestly; it does not review prose craft.
• OpenAPI/REST API documentation - Swagger UI / Redoc / Scalar / Mintlify renderer selection, OpenAPI spec example enrichment, REST SDK generation from an OpenAPI spec (route to api-docs-worker-bee).
• Docs-site platform and hosting - Docusaurus / Starlight / Mintlify / GitBook selection, docs-as-code CI for a whole site, search setup (route to docs-site-worker-bee).
• README authoring as a standalone deliverable (route to readme-writing-worker-bee).
• The library/ knowledge convention or general knowledge capture docs (route to library-worker-bee / knowledge-worker-bee).
• Deeplake dataset schema design (route to vector-store-worker-bee).

First action when this stinger is loaded

Read these in order before doing anything else:

1. guides/00-principles.md - doc honesty, the five quality gates, when to route elsewhere, and the core invariants (general, not product-specific).
2. guides/01-mcp-tool-docs.md - how to document any schema-selected tool from its real registration and handler. Read this before documenting any tool.
3. research/distilled-mcp-tool-docs.md - the current synthesis: honest MCP tool docs (including annotations), TypeScript API reference generation beyond TypeDoc, CLI documentation conventions, doc-to-code sync tooling, and changelog automation.

Then walk the remaining guides in task order. Each guide teaches the general practice first, then points to the matching examples/*.md file for a worked Hivemind case. Always read the real source before writing - these docs are honest about the code or they are wrong.

Surfaces to document

Worked example (Hivemind): the MCP tools shipped today are hivemind_search, hivemind_read, and hivemind_index (stdio transport, read-only, auth via ~/.deeplake/credentials.json); OpenClaw additionally contracts hivemind_goal_add and hivemind_kpi_add (write tools). The TS public API is rendered with TypeDoc from src/index.ts. The CLI (hivemind install [--only <platforms>] [--skip-auth] [--token <value>], hivemind <agent> install, hivemind uninstall, hivemind login, hivemind status, hivemind update [--dry-run], plus goal/kpi/context/graph/dashboard/rules/skillify/embeddings <sub>) is documented from src/cli/index.ts routing - never from memory. The changelog tracks @deeplake/hivemind, single-sourced via scripts/sync-versions.mjs. See guides/01-mcp-tool-docs.md through guides/05-changelog.md for the general procedure each of these demonstrates, and examples/*.md for the worked docs themselves.

Cross-links (adjacent Bees - route there instead of duplicating)

This stinger owns the source-derived reference-docs layer for tool, API, and CLI surfaces. Three adjacent stingers own territory this one does not - cross-link rather than re-teaching their material:

• technical-writing-craft-stinger - the craft of writing well: Diataxis mode classification, inverted-pyramid structure, code-example discipline, voice/tone, ghostwriting, docs-as-code prose review. Use it when the question is "is this well-written," not "does this doc match the code."
• api-docs-stinger - OpenAPI/REST API documentation specifically: Swagger UI / Redoc / Scalar / Mintlify / Stoplight / Bump.sh tool selection, OpenAPI spec example enrichment, REST SDK generation (openapi-generator-cli, Fern, Speakeasy). Use it for a REST API's OpenAPI spec and its renderer; use this skill for the TypeScript SDK's exported symbols and any MCP/CLI surface.
• docs-site-stinger - documentation-site platform selection and hosting (Docusaurus, Starlight, Mintlify, GitBook, MkDocs Material, Nextra, Fern), docs-as-code CI for a whole site, search setup. This skill's generated API reference is often published inside one of those sites - picking and running the site itself belongs there.

Critical directives (lifted from the Command Brief)

These are non-negotiables. Full justification in guides/00-principles.md.

• Read the source before writing a single line. A tool doc that does not match src/mcp/server.ts is a bug, not documentation.
• Tool descriptions and schemas must match real behavior. The zod inputSchema, the output content shape, and the side effects are facts, not prose. Honest or wrong, no middle.
• Every MCP tool doc carries six parts: name, purpose, input schema (from zod), output shape, side effects, and at least one example.
• TypeDoc renders from the TS types, not hand-written prose. Fix the doc comment in the source; never fork the truth into a separate file.
• The changelog is tied to the npm version. scripts/sync-versions.mjs single-sources the version; the changelog tracks @deeplake/hivemind releases, not arbitrary dates.
• Do not scope-creep into protocol internals or README authoring. Route to mcp-protocol-worker-bee / readme-writing-worker-bee.
• This is a general documentation practice, not a single-product skill. The Hivemind-specific facts above still hold exactly as written for Hivemind; when documenting any other project's tools, API, or CLI, apply the same shape (six-part tool docs, generated API references, source-derived CLI references, single-sourced changelog versions) to that project's real source instead.
• Set and check MCP tool annotations, not just prose side effects. Where a server defines readOnlyHint / destructiveHint / idempotentHint / openWorldHint, the tool doc records the real values and flags any contradiction with the prose side-effect claim; where none are set, say so and note the pessimistic default a client will assume.
• Do not scope-creep into OpenAPI/REST docs, docs-site platform work, or prose-craft review. Route to api-docs-worker-bee, docs-site-worker-bee, or technical-writing-craft-worker-bee respectively - see Cross-links above.
