Use this skill when the user asks to grade, review, score, improve, rewrite, harden, sanity-check, or optimize a Codex `/goal` prompt or any long-running autonomous Codex objective. Trigger for phrases like "grade this /goal", "is this a good goal", "optimize my goal", "score my autonomous task", "goal grader", or when a prompt starts with `/goal` and the user wants feedback before running it. The skill grades execution readiness, identifies blockers, and returns a safer optimized `/goal` rewrite.
