#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 install

Install 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.
