 By default, the CLI installs skills into `./skills` under your current working directory. Clawdbot loads workspace skills from `<workspace>/skills` and will pick them up in the **next** session. If you already use `~/.clawdbot/skills` or bundled skills, workspace skills take precedence.

+## ClawdHub (install + sync)
+
+ClawdHub is the public skills registry for Clawdbot. Use it to discover,
+install, update, and back up skills. Full guide: [ClawdHub](/tools/clawdhub).
+
+Common flows:
+
+- Install a skill into your workspace:
+  - `clawdhub install <skill-slug>`
+- Update all installed skills:
+  - `clawdhub update --all`
+- Sync (scan + publish updates):
+  - `clawdhub sync --all`
+
+By default, `clawdhub` installs into `./skills` under your current working
+directory; Clawdbot picks that up as `<workspace>/skills` on the next session.
