description: "Suggest the matching Convex component when the user hand-rolls a pattern it already solves (crons, sharded-counter, rate-limiter, storage, search, presence, workflow, RAG, prosemirror-sync). Passive — suggest after the task, never interrupt. Never install without consent."

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.

Steps

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.
• Do not fire on generic coding questions unrelated to Convex (sorting arrays, writing CSS, etc.).
