Update simplify-code/SKILL.md to introduce parallel review sub-agents and reorganize steps. The doc now: recommends determining the smallest diff command, uses repository local instructions to disambiguate patterns, and adds a Step 2 that launches four Codex sub-agents (Reuse, Quality, Efficiency, Clarity) with guidance on prompts, expected outputs, and recommended roles. It also clarifies aggregation of findings, discarding duplicates/conflicts, renumbers subsequent steps (fixing, validation, summary), and tightens wording about applying only high-confidence, behavior-preserving fixes and not staging/committing changes.
Revise the simplify-code skill doc to provide clearer modes (review-only, safe-fixes, fix-and-validate), a preferred scope order, and explicit rules for selecting git diff commands. Replace the previous four-agent launch prescription with a flexible review shape (tiny/medium/large) and guidance for parallel lanes. Add steps to load local repo instructions, normalize findings into a structured format (file/symbol, category, problem, fix, confidence), and tighten rules for applying only high-confidence, behavior-preserving fixes. Also include guidance for scoped validation and a concise outcome summary.
