/simplify

Reviews changed code for cleanup opportunities (reuse, simplification, efficiency) and applies the fixes directly, without hunting for correctness bugs.

Reviews changed code for cleanup opportunities (reuse, simplification, efficiency) and applies the fixes directly, without hunting for correctness bugs. [Skill] Four review agents run in parallel: reuse, simplification, efficiency, abstraction level. From v2.1.154, no bug hunting (use /code-review for that). A path or PR reference can be given as the target.

✅ WHEN TO USE IT?

Clean up after a finished feature

Once a feature already works and is tested, run /simplify on the changed code to improve reuse, simplification, and efficiency.

Clean up one path without bug hunting

Call /simplify src/utils/parser.ts to clean up just that file without also hunting for correctness bugs.

⛔ WHEN NOT TO?

Bugs need to be found too

Per the docs, since v2.1.154 /simplify explicitly no longer hunts for correctness bugs, only cleanup potential.

Better: Use /code-review, which also covers correctness bugs.
