perf-loop

A configuration of [loop-controller]. That skill supplies the loop machinery — primitive selection, the full guardrail stack, state externalization. This skill supplies the two things specific to "make it hit the budget": a measured proof under repeatable conditions (a named benchmark artifact, default-FAIL) and the measurement discipline that keeps a noisy benchmark from lying to the loop. Read loop-controller for the guardrails; they're inherited, not repeated here.

Why disable-model-invocation: this loop edits and commits code on its own and spends real time re-running benchmarks until a metric is under target. You want to type /perf-loop (or have the orchestrator dispatch it) — not have Claude start an autonomous optimize loop because a number looked slow.
