Trigger.dev used to install per-tool rule files (.cursor/rules/trigger.*.mdc, regions in CLAUDE.md, and so on) fetched from GitHub. That has been replaced by agent skills: SKILL.md directories in the open Agent Skills standard that install with the CLI, draw their API guidance from a version-pinned reference in @trigger.dev/sdk, and load on demand instead of always sitting in your context.
The install command is the same, and now installs skills:
npx trigger.dev@latest skills
npx trigger.dev@latest install-rules still works as an alias for skills, and trigger dev offers to install the skills on first run.
The old task and realtime guidance now lives in the trigger-authoring-tasks and trigger-realtime-and-frontend skills, alongside two new skills for building chat.agent AI agents. See Skills for the full list and supported assistants.
