Code Simplifier

Use this skill after making changes and before wrapping up.

Workflow

1. Inspect the relevant diff or latest modified files.
2. Review for existing utilities that should be reused.
3. Review for code smell: parameter sprawl, copy-paste, leaky abstractions, or unnecessary comments.
4. Review for efficiency problems: repeated work, unnecessary reads, event churn, and hot-path bloat.
5. 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
