Use this skill after making changes and before wrapping up.

Workflow

• Inspect the relevant diff or latest modified files.
• Review for existing utilities that should be reused.
• Review for code smell: parameter sprawl, copy-paste, leaky abstractions, or unnecessary comments.
• Review for efficiency problems: repeated work, unnecessary reads, event churn, and hot-path bloat.
• Fix confirmed issues and summarize what changed.

Guardrails

• Prefer concrete fixes over broad stylistic churn.
• Keep attention on changed code, not the whole codebase.
• If no issue exists, say so explicitly.

Example Requests

• Review my diff for duplicate logic and unnecessary complexity.
• Clean up this changed code before I ship it.

Inputs

• Relevant diff or changed files
• Optional focus area

Outputs

• Concrete cleanup changes
• Short summary of improvements

Success Criteria

• Duplication or awkward abstractions were reduced.
• Performance regressions were checked.
• No unnecessary churn was introduced.

Non-Goals

• Massive style-only rewrites
• Review of untouched code with no link to the change
