Agent Command Center (ACC)

A minimal macOS menu bar app that watches active pi, claude, and codex CLI sessions.

What it does

• lives in the macOS status bar
• scans running processes for interactive Pi / Claude / Codex sessions
• shows whether each session is still running
• derives a human title from local agent history when possible
  • Pi: ~/.pi/agent/sessions
  • Claude: ~/.claude/history.jsonl
  • Codex: ~/.codex/history.jsonl
  • fallback: shell history / working directory
• lets you open the owning terminal app
• lets you cancel a session with SIGTERM

Build and run

cd agent-command-center
swift test
swift run ACC

To validate process discovery from the terminal without opening the menu bar UI:

swift run ACCDebug

You can also open Package.swift directly in Xcode and run the ACC target as a normal macOS app.

Notes

• Exact tab focusing is implemented for Terminal.app and iTerm.
• The first time you use Open, macOS may ask for Automation permission.
• For other terminal apps, ACC falls back to activating the owning app.
• Background Codex helper app-server processes are intentionally ignored so the menu stays focused on interactive sessions.
