What problem does it solve? Performance optimization work often drifts without a measurable pass/fail contract, making it impossible to know when an objective is actually done. This Skill enforces an evaluator-first loop so every optimization is validated against a declared benchmark before completion. ## Core Features & Use Cases - Evaluator-Gated Workflow: No optimization begins until an evaluator command and pass/fail contract are defined via omx performance-goal create. - Durable State Artifacts: Workflow state persists under .omx/goals/performance/<slug>/, surviving across sessions and threads. - Checkpoint Tracking: Record pass, fail, or blocked evaluator outcomes with evidence for each iteration. - Safe Codex Goal Handoffs: Coordinates with Codex goal mode (create_goal, update_goal, get_goal) without shell commands mutating hidden goal state. - Use Case: A developer wants to reduce CLI startup latency by 20%. They create the goal with a benchmark evaluator, iterate in small reversible patches, checkpoint each run, and complete only after a passing checkpoint and completion audit. ## Quick Start Ask the agent to start a performance goal for reducing startup latency by 20% using your benchmark command as the evaluator contract.
