Skill Metadata

Name
convex
Description
Routes Convex work to the right builder skill and covers the handful of rules that apply everywhere: validators on every function, withIndex over filter, idempotent mutations, internal functions for scheduling. Use when a task mentions Convex and no more specific skill matches, or as the first stop before picking one.

Convex

Start here, pick the matching skill below, and load it. If nothing matches, the rules at the bottom still apply.

Pick a skill

| Skill | Load when | | --- | --- | | convex-best-practices | general patterns, project structure, "is this the Convex way" | | convex-functions | queries, mutations, actions, internal functions, error handling | | convex-schema-validator | tables, indexes, validators, v.* types, schema changes | | convex-realtime | useQuery, optimistic updates, pagination, presence, rerender churn | | convex-http-actions | webhooks, REST endpoints, convex/http.ts, Stripe or Clerk callbacks | | convex-file-storage | uploads, upload URLs, serving files, storage cleanup | | convex-cron-jobs | crons.ts, runAfter, runAt, batching, a cron that is not firing | | convex-migrations | backfills, renaming fields, schema evolution with live data | | convex-agents | AI agents, threads, tools, streaming, RAG with @convex-dev/agent | | convex-component-authoring | building a reusable component package, defineComponent | | convex-security-check | fast pre ship audit: auth on public functions, exposed data | | convex-security-audit | deep review: authorization model, injection, rate limits, secrets | | avoid-feature-creep | scope pushback, MVP cuts, "just one more feature" | | project-workflow | multi step tasks, PRDs in prds/, task.md, plans for review | | project-docs | syncing task.md, changelog.md, files.md with shipped code | | git-safety | revert, undo, reset, checkout, clean, stash, force push |

Two skills often apply at once. Load the domain skill for the code and the process skill for the workflow, for example convex-functions plus project-workflow.

Rules that hold everywhere

  • Every function declares args and returns validators, including internal ones.
  • Read through withIndex. .filter() on a table scan is a bug waiting for data.
  • Mutations are idempotent. Check current state, return early when there is nothing to do.
  • Schedule and cron only internal.* functions. Never api.*.
  • Never call Date.now() inside a query. Pass time in as an argument.
  • Use npx convex dev for development. Do not run npx convex deploy unless asked.
  • Fetch https://docs.convex.dev/llms.txt before trusting memory about an API.

Do not

  • Edit anything under convex/_generated/.
  • Use crons.daily, crons.hourly, or crons.weekly. Use crons.interval or crons.cron.
  • Put "use node" in a file that also exports queries or mutations.
  • Run git commands that discard work without loading git-safety first.
