 - **Claude Code**: `~/.claude/settings.json`
 - **Codex**: `~/.codex/config.toml`
 - **Gemini CLI**: `~/.gemini/settings.json`
+- **Oh My Pi (omp)**: `~/.omp/agent/extensions/code-notify.js`
 
 For Codex, Code-Notify configures `notify = ["/absolute/path/to/notifier.sh", "codex"]` and reads the JSON payload Codex appends on completion.
 Codex currently exposes completion events through `notify`; approval and `request_permissions` prompts do not currently arrive through this hook.
 
+For omp, Code-Notify writes a small managed extension module to `~/.omp/agent/extensions/code-notify.js`, because omp loads extension modules instead of reading hook commands from a config file. The extension forwards omp's `agent_end` event to the same `notifier.sh`, so sound, voice, Slack/Discord channels, click-through, the global mute switch, and rate limiting all work unchanged. Like Codex, omp currently exposes completion events; approval and idle prompts are not yet wired.
+
 When enabled, it adds hooks that call the notification script when tasks complete:
