+## Upgrading from v3.0.x

+If you installed OCP before v3.1.0, the auto-start service used names that OpenClaw's gateway detected as conflicting (`ai.openclaw.proxy` on macOS, `openclaw-proxy` on Linux). Running `node setup.mjs` or `ocp update` will automatically migrate to the new neutral names.

-## Known Issues
-
-### `/ocp` command returns "Unknown skill: ocp" (OpenClaw only)
-
-The `/ocp` plugin command may intermittently stop working in Telegram/Discord. This is caused by an OpenClaw gateway bug ([openclaw/openclaw#26895](https://github.com/openclaw/openclaw/issues/26895)).
-
-**Workaround:**
-```
-/new
-/ocp restart
-```
-
-**Important:** Do not add `ocp` to agent `skills` lists or place a `SKILL.md` in workspace skills — this creates a routing conflict.
