# convex-suggest

The skill notices when you hand-roll something a ready Convex component already solves, and offers one match after your task is done.

## What it does

It watches your code snippets and your ask passively, without blocking the current task. When a pattern shows up that a component already covers, it waits until the task is finished, then names one component, quotes the exact line that triggered it, and explains why the component fits better. Spot `post.likes + 1` inside a mutation many users call at once, and it will point at OCC conflicts under load.

Detector rules map the patterns: `setInterval` or cron to `@convex-dev/crons`, shared counter increments to `@convex-dev/sharded-counter`, `.collect().length` scans to `@convex-dev/aggregate`, long-running multi-step actions to `@convex-dev/workflow`, bounded concurrency to `@convex-dev/workpool`, rate-limit counters in the database to `@convex-dev/rate-limiter`, file uploads to Convex Storage, Elasticsearch or Algolia to built-in full-text search, presence and typing to `@convex-dev/presence`, an external vector database to `@convex-dev/rag`, collaborative editing to `@convex-dev/prosemirror-sync`.

The skill never installs anything on its own. Say yes and it runs `/add <component>` or follows the detector's install hint. Say no or ignore it and the suggestion is dropped for good. On generic coding questions unrelated to Convex, it stays quiet.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add convex/agent-skills --skill convex-suggest -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-suggest/SKILL.md

## When to use it
- replace a hand-rolled like counter with sharded-counter
- move a cron job onto `@convex-dev/crons`
- drop `.collect().length` scans in favour of aggregate
- swap homemade database counters for rate-limiter
- route long multi-step actions through workflow

## Example prompts
- I just finished a mutation that increments likes — check whether a Convex component already does this
- Look at my code for cron jobs and tell me if there's a matching component
- Is there a Convex component for presence and typing if I'm writing it myself?

# Proactively suggest the right Convex component

When you see code or intent that duplicates what a Convex component already does, surface a targeted suggestion: ONE component, WHY (anchored in the user's own code or ask), and a concrete install hint. Never install without explicit consent. Never suggest more than one component at a time unless the user asks.

## Workflow

1. Observe the codeSnippets and userAsk passively — never block the current task to suggest.
2. Match against the detector rules (see generators/suggest-detector.mjs): email/SMTP → resend; push notifications → expo-push; setInterval/cron → @convex-dev/crons; shared counter increments → @convex-dev/sharded-counter; .collect().length scans → @convex-dev/aggregate; multi-step/long-running actions → @convex-dev/workflow; bounded concurrency → @convex-dev/workpool; rate-limit counters in DB → @convex-dev/rate-limiter; fs.write/S3 uploads → Convex Storage; Elasticsearch/Algolia → built-in full-text search; presence/typing → @convex-dev/presence; Pinecone/external vector DB → @convex-dev/rag; collaborative editing → @convex-dev/prosemirror-sync.
3. After finishing the current task, offer ONE suggestion: name the component, quote the specific code or phrase that triggered it, explain why the component fits better.
4. If the user says yes: run `/add <component>` or follow the installHint from the detector.
5. If the user says no or ignores it: drop it. Do not repeat the same suggestion.

## Rules

- Passive — never interrupt the current task; surface the suggestion AFTER completing what the user asked.
- One at a time — pick the highest-priority match; do not dump a list of five components.
- Cite WHY from the user's own code or ask — 'I noticed you wrote `post.likes + 1` in a mutation that many users call concurrently; that causes OCC conflicts at scale.'
- Never install without explicit consent — suggest, explain, wait for a yes.
- Do not suggest a component the user has already installed.
