Agent rules are now agent skills. The standalone rule files have been replaced by skills that
work across every major AI assistant from a single install. See Skills.
What changed
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 That has been replaced by agent skills: SKILL.md directories in the open Agent Skills standard that ship inside the CLI, version-matched to the Trigger.dev version you build against, 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 install-rules still works as an alias, and trigger dev offers to install the skills on first run.
The old task and realtime guidance now lives in the authoring-tasks and realtime-and-frontend skills, alongside two new skills for building chat.agent AI agents. See Skills for the full list and supported assistants.
