+In this compose setup, PicoClaw reads the workspace from `docker/data/workspace` on the host, so local skills must live under `docker/data/workspace/skills`. The repo checkout's `workspace/skills` directory is not mounted into the container.
+
 > [!TIP]
 > **Docker Users**: By default, the Gateway listens on `127.0.0.1` which is not accessible from the host. If you need to access the health endpoints or expose ports, set `PICOCLAW_GATEWAY_HOST=0.0.0.0` in your environment or update `config.json`.
