taskchad-os: Skill for Claude Code

Desktop Agent

Native daemon at ~/.claude/live-chat/desktop_agent.py that watches a command queue and executes actions on the real Windows desktop. Runs as pythonw (no console window).

All commands go through desktop_cmd.py which auto-starts the agent if not running.

Commands

DCMD="python ~/.claude/live-chat/desktop_cmd.py"

# Open a live chat terminal
$DCMD open-chat --ctx thehomie
$DCMD open-chat --ctx deployment-a
$DCMD open-chat                          # all contexts

# Open URL in default browser
$DCMD open-url --url https://example.com

# Open file in default app
$DCMD open-file --path "~/some-file.pdf"

# Run any command in a new visible terminal window
$DCMD run --command "npm start" --title "Dev Server"
$DCMD run --command "ssh [email protected]" --title "SSH"

# Windows toast notification
$DCMD notify --title "Build Done" --message "deployment finished"

# Agent management
$DCMD status                             # check if running + PID
$DCMD ensure                             # start if not running

How It Works

1. desktop_cmd.py appends a JSON command to ~/.claude/live-chat/commands.jsonl
2. desktop_agent.py (running natively via pythonw) polls the file every 500ms
3. Agent reads the command and executes it with full Windows desktop access
4. Single-instance: PID lock with ctypes OpenProcess (not broken os.kill)
5. Auto-start: VBScript in Windows Startup folder, also desktop_cmd.py starts it on demand

Anti-Zombie Guarantees

• Single instance enforced via PID file + live process check (ctypes, not os.kill)
• atexit handler cleans PID file on exit
• Stale PID file from dead process gets overwritten (checks STILL_ACTIVE exit code)
• subprocess.Popen with shell=True for start commands — child terminals are independent
• Agent log at ~/.claude/live-chat/state/desktop-agent.log

Auto-Start

VBScript at shell:startup runs pythonw desktop_agent.py on Windows login. No console window. If the agent dies, next desktop_cmd.py call restarts it.
