# Agent rules

> Trigger.dev agent rules are now agent skills, installed with the trigger.dev CLI.

> [!NOTE]
>
> 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 The standalone rule files have been replaced by skills that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](https://trigger.dev/docs/skills.md).

## 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 That has been replaced by [agent skills](https://trigger.dev/docs/skills.md): `SKILL.md` directories in the open [Agent Skills standard](https://agentskills.io) that install with the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:

```bash theme={"theme":"css-variables"}
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](https://trigger.dev/docs/skills.md) for the full list and supported assistants.
