simplify-code

Ask the agent to simplify your changes. It captures the git diff, runs four parallel reviewers covering reuse, quality, efficiency, and altitude, then applies safe fixes like removing unused imports and commented-out code while running targeted tests to verify nothing breaks.

The skill uses delegate_task batch mode to launch four reviewers concurrently, each receiving the complete diff plus repo access. Each reviewer searches the codebase for evidence in its specialty area, then findings are merged, deduplicated, and applied by risk tier.

Yes, request a dry run by saying simplify but don't change anything. The four reviewers still run and present all findings across the SAFE, CAREFUL, and RISKY tiers, but nothing is applied until you approve.

The skill falls back to an inline single-pass review where all four reviewer angles are worked through sequentially in the current context with the same standards. The final summary clearly states it was an inline review rather than the parallel fan-out.

Avoid it for hunting correctness bugs, which belongs in a dedicated code review pass, and for large-scale refactoring of shared infrastructure. RISKY findings like public API renames or N+1 restructuring are flagged for human decision rather than auto-applied.
