-- **Install once, sync everywhere** — propagate skills across your agent stack
+- **Install once, use everywhere** — propagate skills across your agent stack with one click
+- **Clean house per-agent** — right-click an agent to copy every skill from another or wipe them all
+- **Project-scoped skills** — pin a skill to a specific repo without polluting your global setup
 - **Edit confidently** — update `SKILL.md` content with immediate local visibility
 - **Discover faster** — browse marketplace sources like [skills.sh](https://skills.sh) and [ClawHub](https://clawhub.ai)
-- **Stay up to date** — refresh and manage skills without manual filesystem work
