#oh-my-pi
oh-my-pi is a fork of Pi rewritten as a coding-first agent. Its binary is omp, and cmux integrates with it through the omp hooks extension.
#Setup and usage
bun install -g @oh-my-pi/pi-coding-agent
# or
brew install can1357/tap/omp
cmux hooks setup omp
# or
cmux hooks omp installInstall omp, then install the cmux hooks extension. The extension is written to ~/.omp/agent/extensions/cmux-omp-session.ts, and cmux upgrades it in place when the bundled version changes.
#What you get
The hooks extension lets omp report lifecycle and session information back to cmux:
- Workspace busy and idle status from omp turn boundaries
- Turn-end notifications in cmux
- Session tracking so closed panes can be resumed or forked from the session index with omp --session SESSION_ID, adding --fork for forks
- Workspace auto-naming, with omp available as the summarizer model
- Task Manager process attribution for omp processes
#Directories
cmux reads omp data from the agent directory. PI_CODING_AGENT_DIR or PI_CONFIG_DIR can override that directory.
