copilot

Copilot delegation — router

This is the umbrella skill for delegating work from the host agent (Codex or Claude Code) to GitHub Copilot CLI. Each $copilot:<command> has its own sub-skill at skills/<command>/SKILL.md. This file routes free-form requests to the right one.

Sub-skills

Skill	Slash command	Purpose
setup	$copilot:setup / /copilot:setup	Verify CLI install + auth
review	$copilot:review / /copilot:review	Copilot review on the branch
adversarial-review	$copilot:adversarial-review	Hostile-framed review
rescue	$copilot:rescue <task>	Arbitrary task delegation
status	$copilot:status [job-id]	List/inspect tracked jobs
result	$copilot:result <job-id>	Print final transcript
cancel	$copilot:cancel <job-id>	Terminate a background job

Routing rules

• "review", "check my work", "second opinion", "audit this PR" → review
• "red team this", "harsh review", "challenge my assumptions", "what am I missing" → adversarial-review
• "ask Copilot to ", "have Copilot ", "delegate " → rescue
• "is that job done", "what's running", "poll the Copilot job" → status
• "what did Copilot say", "show me the output of " → result
• "kill the Copilot job", "stop the background run" → cancel
• "is Copilot installed", "set up Copilot", first-time error → setup

If the user wants to use a specific model from Copilot's lineup but the task type isn't named, default to rescue with --model <id>.

Shared invariants

All sub-skills share these properties:

• They go through scripts/copilot-exec.sh, which reads HOST=codex|claude to pick the state dir.
• They never silently retry. Auth, quota, and sandbox errors are surfaced to the user verbatim.
• Each invocation consumes one Copilot premium request.
• -p mode does not load MCP servers (github/copilot-cli#633) — sub-skills that need MCP fall back to suggesting an interactive Copilot session.

Model selection

Copilot's default is Claude Sonnet 4.5. Override with --model <id> on any command. Available identifiers depend on the CLI version and the user's subscription; the CLI itself doesn't enforce an enum, so pass whatever model id the user names. The /model interactive command in Copilot is the source of truth for what their account can use.
