Authoring Trigger.dev Tasks

The full, version-pinned reference for authoring tasks ships inside your installed @trigger.dev/sdk. Read it before writing code — it always matches the SDK version in this project, so it never drifts:

• Skill: node_modules/@trigger.dev/sdk/skills/trigger-authoring-tasks/SKILL.md — the complete guide (setup, schemaTask, retries, triggering + the Result shape, idempotency, waits, metadata, scheduled tasks, queues/concurrency, trigger.config.ts).
• Docs: the full, version-pinned docs ship bundled at node_modules/@trigger.dev/sdk/docs/; the skill above lists the exact pages it draws from in its sources: frontmatter. Grep for an API, e.g. grep -rl "schemaTask" node_modules/@trigger.dev/sdk/docs/.

If those paths don't exist, @trigger.dev/sdk isn't installed yet — install it first. In a non-hoisted layout, resolve the package with node -p "require.resolve('@trigger.dev/sdk/package.json')" and read skills/ + docs/ beside it.

Always import from @trigger.dev/sdk — never @trigger.dev/sdk/v3 (deprecated alias) or @trigger.dev/core.

Common mistakes

1. CRITICAL: Treating the wait result as the output. triggerAndWait and wait.forToken return a Result object, not the raw output.
   • Wrong: const out = await childTask.triggerAndWait(p); use(out.foo);
   • Correct: const r = await childTask.triggerAndWait(p); if (r.ok) use(r.output.foo); (or .unwrap()).
