 ### Install skills into your project
 
-To install skills locally or commit them to your project repository, use the `skills` CLI:
+Fetching on demand (above) needs no setup. To make skills part of a project instead, choose one of two installs:

+**Pin them (any agent).** Version-lock skills into your repo with the `skills` CLI:
 
 ```bash
 npx skills add dfinity/icskills
 ```
 
-This prompts you to choose your agent (Claude Code, Cursor, Windsurf, GitHub Copilot, and others) and installs the selected skills into the correct location for that agent.
+This detects your agent (Claude Code, Cursor, Windsurf, GitHub Copilot, and others), installs the skills into the right location, and writes a `skills-lock.json`. Refresh them later with `npx skills update`.
+
+**Auto-update them (Claude Code).** Install the [`autosync-ic-skills`](https://skills.internetcomputer.org/.well-known/skills/autosync-ic-skills/SKILL.md) skill to add a `SessionStart` hook that keeps `.claude/skills/` mirroring the latest skills automatically, every session.

+> **Scaffolding with icp-cli?** Projects generated by `icp new` ship an `AGENTS.md` that walks your agent through choosing one of these modes (fetch on demand, pin, or auto-update) and then configures itself. See [how that works](https://github.com/dfinity/icp-cli-templates/blob/main/AGENT_SKILLS.md).
