Goal Supervisor

When the claude process orchestrating a /goal dies, its subagents survive but nothing drives the loop anymore. The state, however, lives on in the session transcript — claude -p --resume <session-id> picks it back up with full context. This skill launches supervise.sh (in the same directory as this SKILL.md — resolve the absolute path from it) to exploit that in a one_for_one supervision tree:

launchd/systemd/tmux (optional) ← keeps the supervisor alive
  └── supervise.sh              ← restart policy + backoff + stall detection
        └── claude -p /goal     ← worker, session pinned via --session-id
              └── subagents     ← survive on their own; the worker re-adopts state
