What convex-docs does

The skill prevents agent hallucinations when Convex renames an API or updates a CLI flag. It starts by pinning the exact installed version of convex and any @convex-dev/* components through package.json or by reading the package manifest via Node.js.

To find accurate syntax, it follows a strict freshness hierarchy. The agent first queries the search_convex_docs MCP tool when available. If that tool is missing, it fetches the raw markdown page from docs.convex.dev/<path> or the component README at the pinned version. General web search is strictly a fallback with unverified versioning.

When an export is doubtful, the skill checks local .d.ts typings and package exports inside node_modules/@convex-dev/<x>/ as the ground truth. It extracts the raw signature, cites the source, and lets convex-expert handle idiomatic code. A missing export during a build is treated as a version mismatch rather than an invitation to guess names.

What it helps with

  • verify Convex API signatures against the installed version
  • fetch CLI flags directly as markdown documentation
  • check component exports inside node_modules using .d.ts files
  • resolve build errors caused by package version mismatches

Example prompts for the agent

  • Check the docs for our pinned convex version to see how to declare a mutation with argument validation
  • Inspect node_modules/@convex-dev/auth to verify exports for our installed version
  • Fetch docs.convex.dev to check the current CLI flags for convex dev

Questions about convex-docs

How to install convex-docs in Claude Code?

Run npx skills add convex/agent-skills --skill convex-docs -a claude-code.

What does convex-docs do?

It forces the coding agent to pin the project's installed Convex version and pull current markdown documentation or inspect local types instead of relying on stale memory.

How does convex-docs verify component exports?

The skill inspects local .d.ts declaration files and the exports field inside node_modules/@convex-dev/<x>/. These installed typings take precedence over web documentation as the absolute ground truth.

# Pull version-current Convex docs

convex-expert carries baked, plugin-versioned knowledge — excellent for stable idioms, but it goes stale exactly where it hurts: a component that gained a new export, a CLI flag that changed, an API renamed between versions. This capability is the freshness discipline layered on top: pin to the project's real version, fetch the live page cheaply as markdown, and never write an unfamiliar API from memory when the current source is one fetch away.

## Workflow

1. PIN the version: read the installed `convex` version (`node -p "require('./node_modules/convex/package.json').version"` or `package.json`), and the versions of any `@convex-dev/*` components in play. The docs you trust must match THESE versions — version skew is the single largest source of wrong Convex code.
2. FRESHNESS HIERARCHY (cheapest-correct first, the Supabase-taught order):
   (a) if a served docs tool / MCP `search_convex_docs` is available, use it (it returns version-scoped, reranked answers sized to the context window);
   (b) else fetch the specific docs page as MARKDOWN — request `docs.convex.dev/<path>` and prefer a `.md`/markdown form when the site serves one (far fewer tokens than HTML), or the component's README at the pinned version;
   (c) only then fall back to a general web search, and treat its version as unverified.
   Do NOT skip to writing the API from memory when currentness is in doubt.
3. VERIFY against the installed package when it matters: for a component export you're unsure exists, check `node_modules/@convex-dev/<x>/` (its `package.json` `exports`, its `.d.ts`) — the installed types are the ground truth for THIS version, more authoritative than any doc.
4. USE the fetched fact narrowly: apply the current signature/flag, cite where it came from (page + version), and hand the actual code back to convex-expert to write idiomatically. convex-docs supplies the fresh fact; convex-expert supplies the idiom.
5. On a version-mismatch build error (an export/flag that 'should' exist but doesn't): treat it as a currentness question — pin the version, fetch the current API, and correct — rather than guessing a different spelling.

## Rules

- Never write an unfamiliar or possibly-renamed Convex/component API from model memory when currentness is in doubt — pin the version and fetch the current source first.
- The installed package's own `exports`/`.d.ts` in node_modules is the ground truth for this version — more authoritative than any doc page.
- Follow the freshness hierarchy: served docs tool → page-as-markdown / pinned README → general web (unverified) — cheapest-correct first, fewest tokens.
- Prefer markdown over HTML doc pages — far fewer tokens for the same content.
- Supply the fresh FACT; hand idiomatic code back to convex-expert. This is a freshness layer, not a replacement for the baked knowledge.
- A version-mismatch build error is a currentness question, not a spelling guess — re-pin and re-fetch.
