Lookup Docs

Fetch current documentation for libraries used in channelhub (Bun, grammy, MCP SDK, Playwright, bun:sqlite, etc.). Prefer Context7 when installed; fall back to WebFetch against the canonical doc site. Use when the user asks "how does X API work" or you're about to call an unfamiliar library method.

Look up library documentation

Why this exists

Channelhub leans on libraries that move faster than the model's training cut. Today's debugging hit at least three "is this current?" moments:

bun:sqlite API — added relatively recently, semantics drift
Bun.spawn env / cwd inheritance — caught us out on the CI cwd bug
grammy v1.x command registration — bot.api.setMyCommands shape
MCP SDK request handlers (CallToolRequestSchema, notification handlers)

Pulling current docs catches version drift instantly.

Preferred path: Context7

If the Context7 plugin is available (auto-loaded MCP tools resolve-library-id, get-library-docs), use it:

1. resolve-library-id with the library name → get a Context7 ID
2. get-library-docs with that ID + a topic → get current snippet

Install Context7 once, project-wide:

# As a Claude Code plugin (recommended):
/plugin install context7@anthropic-marketplace

# Or as a user-scope MCP server (works in any client):
claude mcp add context7 -- npx -y @upstash/context7-mcp

After install, restart Claude Code in this repo and the tools surface automatically.

Fallback: WebFetch

If Context7 is not available, hit the canonical doc URL directly:

Library	URL pattern
Bun runtime	`https://bun.sh/docs/<topic>`
`bun:sqlite`	`https://bun.sh/docs/api/sqlite`
`Bun.serve`	`https://bun.sh/docs/api/http`
`Bun.spawn`	`https://bun.sh/docs/api/spawn`
grammy	`https://grammy.dev/guide/<topic>`
MCP SDK	`https://github.com/modelcontextprotocol/typescript-sdk` (README)
Playwright	`https://playwright.dev/docs/<topic>`
tmux	`https://man.openbsd.org/tmux`

Use WebFetch with a focused prompt — the smaller the question, the better the synthesis.

When NOT to look up

Stable, ancient APIs (Node fs, path, crypto) — model knowledge is fine.
Behavior already proven in this repo — read the source first (grep / Read) before fetching docs. Existing usage IS the docs.

Reply to the user

When you used Context7 / WebFetch to settle a question, say so briefly ("Confirmed via Bun docs: …"). Don't paste raw docs unless it's directly relevant. Cite the URL you fetched so the user can verify if they want.

Note on supportability

Skills can call MCP tools when those tools are exposed to the current Claude Code session. Context7 must be installed at the user / plugin level — this skill cannot install it for you. If resolve-library-id errors with "tool not found", drop to the WebFetch fallback in the same response.
