Profiles, researches, validates, and executes optimization hypotheses until target reached, plateau detected, or budget exhausted. ## Inputs | Input | Required | Description | |-------|----------|-------------| | `target` | Yes | endpoint, function, or pipeline to optimize | | `observed_metric` | Yes | current performance problem | | `target_metric` | No | user or research-derived target | | `max_cycles` | No | default `3` | ## Purpose & Scope - Detect whether optimization is the right tool - Run iterative cycles: `profile -> gate -> research -> target -> context -> validate -> execute` - Preserve optimization artifacts under `.hex-skills/optimization/{slug}/` and runtime state under `.hex-skills/optimization/runtime/runs/{run_id}/` - Resume deterministically from the last checkpointed phase - Keep cycle summaries machine-readable ## Runtime Contract **MANDATORY READ:** Load `shared/references/ci_tool_detection.md` **MANDATORY READ:** Load `shared/references/coordinator_runtime_contract.md`, `shared/refere...
