/copilot — delegate to GitHub Copilot CLI

Spawns Copilot CLI in a detached tmux session so Claude can offload work to it. The user stays in the loop: they ask Claude when to check progress, what guidance to send, and when to stop.

Primitive

All operations go through a single dispatcher:

~/.claude/skills/copilot/bin/copilot-agent [--session <name>] <verb> [args]

Verbs:

• start [task...] — create session (default cc-copilot), launch copilot --allow-all, type the task and press Enter. Returns immediately (non-blocking).
• send <message> — type message + Enter. For follow-up guidance. Does not interrupt current generation; Copilot queues the input.
• keys <name> — send a raw tmux key (Escape, C-c, Enter, etc.). Used for interrupts.
• capture [lines] — print last N ANSI-stripped rendered lines (default 500). Read-only, non-destructive.
• wait [stable] [timeout] — block until copilot goes idle, then exit. Run via a backgrounded Bash so the harness notifies Claude on completion (see "Auto-notify" below). stable = secs the working indicator must stay gone before declaring idle (default 6); timeout = overall cap in secs (default 1800).
• stop — kill-session. Destroys the tmux session.
• list — list active cc-copilot* sessions.

How to respond to the user

Rules:

• Never auto-poll by burning Claude turns on a ScheduleWakeup/timer. For new tasks, arm the wait watcher by default (see Auto-notify), which polls inside a cheap background shell instead. Only capture when the user asks.
• Never send Escape unless the user explicitly asks to interrupt.
• capture is the default observation verb. Prefer it over intervention.

Conventions

• Default session name: cc-copilot. For concurrent tasks, pass --session <name> before the verb.
• Tasks and messages are single-line: newlines are interpreted as submit by the TUI. For long prompts, write the prompt to a file and tell Copilot to read it.

Safety

--allow-all is shorthand for --allow-all-tools --allow-all-paths --allow-all-urls — full autonomy: any tool, any path (including outside the cwd), any URL, no approval prompts. For untrusted tasks, launch inside a git worktree or downgrade to --allow-all-tools alone (paths outside cwd will then prompt interactively).

Auto-notify (get pinged when copilot finishes, no timer)

After start — and after any send that should produce another completion ping — arm a backgrounded watcher. This is the default for /copilot <task>; the user does not need to say "tell me when it's done". The trick is entirely Claude-side: copilot sends no signal. A background shell scrapes the pane and exits when copilot goes idle, and the harness re-invokes Claude on that exit. The polling moves into a cheap shell loop; Claude is woken exactly once.

To arm it, call the wait verb through a backgrounded Bash:

Bash(
  command: "~/.claude/skills/copilot/bin/copilot-agent wait",
  run_in_background: true,
  description: "wait for copilot to go idle"
)

On exit the harness notifies Claude. Read the final stdout line for the state, then capture and report to the user:

Notes:

• Arm wait immediately after start/send — don't capture first. A fast model can finish during the gap, and the watcher will then report no-activity (it never saw the spinner) instead of catching the idle transition. Capture only after the watcher wakes you.
• This is the only sanctioned auto-detection path. Don't substitute a ScheduleWakeup timer (that's autopilot's job, with its own skill).
• The watcher debounces: the working indicator briefly drops between steps, so wait requires it gone for stable secs (default 6) before declaring idle. Bump it for tasks with long gaps between steps.
• Re-arm after each send if you want a ping for that follow-up too — one wait covers one idle transition.
