A proper performance optimization loop that actually profiles before touching code. It cycles through profiling, researching hypotheses, validating plans, and executing changes until you hit your target or reach a plateau. The runtime contract is heavy but precise: it checkpoints phases, coordinates four worker skills (profiler, researcher, validator, executor), and keeps deterministic state under `.hex-skills/optimization/`. The wrong tool gate is smart, it'll tell you to stop if the problem is infrastructure or already good enough. Works in both execute and plan-only modes. If you've ever optimized something three times only to realize the bottleneck was somewhere else, this enforces the discipline you should have had the first time.
