Start Issue in cmux

Use this skill as a thin orchestration layer between start-issue and cmux. start-issue remains the source of truth for GitHub issue resolution, branch naming, worktree creation/reuse, init hooks, prompt rendering, and agent launch. cmux provides the terminal workspace and optional monitoring surfaces.

Preconditions

• The user explicitly requested cmux, a separate tab/workspace, or resume/monitoring of a start-issue run.
• The target repository and issue URL/number are known.
• cmux, start-issue, and git are available.
• Use the repository's normal environment loader. If the repository has .envrc, launch start-issue through direnv exec ..

Do not create a worktree manually. Do not invoke an agent directly when the request is to start an issue: delegate that lifecycle to start-issue.
