## What it 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.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add convex/agent-skills --skill convex-docs -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/convex-docs/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/convex-docs/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add convex/agent-skills --skill convex-docs -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/convex-docs/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add convex/agent-skills --skill convex-docs -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/convex-docs/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install convex/agent-skills convex-docs
```

2. **Manually: put the files in place**
- File: `.github/skills/convex-docs/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add convex/agent-skills --skill convex-docs -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/convex/agent-skills --path skills/convex-docs
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/convex-docs/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add convex/agent-skills --skill convex-docs -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/convex/agent-skills/tree/HEAD/skills/convex-docs/SKILL.md

## When to use it
- 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
- 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

# 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.
