Design and build reactive, type-safe, production-grade backends on Convex. Covers schema, queries/mutations/actions, indexes, auth, file storage, scheduling, real-time multiplayer, mobile backends, and LLM/agent workflows on Convex's one-platform stack.

Wire a domain the user ALREADY OWNS (GoDaddy/Namecheap/Cloudflare/…) to their Convex app: exact DNS records, custom-domain attachment, auth-origin rebind. TRIGGER when the user owns a domain and wants it pointing at their app ('point my domain at this', 'use my own domain', 'set up example.com'). Never asks for registrar credentials.

Set + wire deployment env vars / secrets (API keys) for a Convex app — stored in Convex env, read in actions, never hardcoded. TRIGGER when the user needs an API key/secret/env var ('add my OpenAI key', 'set an env var').

LABS — scaffold a running Next.js + shadcn Convex app with passkey sign-in and a live Chef feedback panel, then build and verify it locally. TRIGGER for the full/labs quickstart, passkeys, or the feedback panel in a new app. For a plain scaffold use quickstart. Legacy convex.app publishing is retired; use a separate hosting workflow if requested. SKIP when a Convex project already exists in the cwd.

Safely migrate the schema + backfill data on a deployed Convex app with @convex-dev/migrations. TRIGGER when changing the schema on a live app, backfilling data, or after a schema-validation error from a change. SKIP a fresh local app.

Scaffold a brand-new Convex app from a one-sentence idea and build it live — a running Next.js + shadcn app with `convex dev` + `next dev` and error watchers already armed, going from idea to running app in under a minute (locally).

Seed the Convex database with starter/fixture data or import an existing dataset (CSV/JSON). TRIGGER when the user wants sample/seed data or to import a dataset into Convex. Idempotent, schema-matching.

Proactively suggest the right Convex component when the user hand-rolls what already exists: setInterval polling → crons, counter increments → sharded-counter, .collect() counts → aggregate, email → resend, DB-counter rate limiting → rate-limiter, uploads → storage, search, presence, multi-step actions → workflow, vector DB → rag, collaborative editing → prosemirror-sync. TRIGGER on noticing the pattern in a Convex app, AFTER completing the user's request. NEVER for non-Convex code.

Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.

Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.

Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to "review since X".

Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent.

Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.

Wire dependency-cruiser into a TypeScript repo so each package is a deep module, with implementation hidden in subfolders and reachable only through its entry-point files. User-invoked.

Conduct a retrospective on a coding session.

Use when completing tasks, implementing major features, or before merging to verify work meets requirements
