Prompt Optimizer

Systematically improve Mycelium instructions through measurement. Adapted from n-trax.

Commands

baseline -- Capture current performance

1. Run /eval-runner run-all
2. Record to .claude/optimization/baseline.json: timestamp, CLAUDE.md hash, overall and per-category metrics (pass_rate, avg_iterations, avg_time)

test <variant> -- Test a variant

1. Read variant from .claude/optimization/variants/<variant>.md
2. Apply the CLAUDE.md changes described
3. Run /eval-runner run-all
4. Store results in .claude/optimization/results/<variant>.json
5. Compare against baseline
6. Do NOT auto-revert -- let user decide

report -- Compare all variants

Generate comparison table: variant, pass rate, delta vs baseline, avg iterations, decision (keep/revert).
