Identify the active scope.
- Start with files changed in the current session, the current diff, or the code the user explicitly points to.
- Expand only when a small adjacent cleanup is necessary to keep the result coherent.
Read project instructions before editing.
- Check for CLAUDE.md, AGENTS.md, lint config, and framework conventions.
- Treat repo-specific rules as higher priority than generic preferences in this skill.
Simplify for readability.
- Reduce unnecessary nesting and indirection.
- Remove redundant helpers, repeated logic, dead branches, and temporary variables when the replacement is clearer.
- Prefer straightforward names and explicit control flow.
- Avoid nested ternaries. Use if/else chains or switch when multiple conditions are involved.
- Prefer function declarations over arrow functions when that matches local standards.
- Add explicit top-level return types in TypeScript when required by project conventions or when they materially improve clarity.
- Keep React components explicit with readable props types and extracted helpers only when they clarify the component.
Preserve exact behavior.
- Do not change outputs, side effects, public APIs, error semantics, async sequencing, or data flow.
- Keep useful abstractions that encode domain meaning or genuinely reduce duplication.
- Remove comments that only restate the code. Keep comments that explain non-obvious intent.
- Avoid adding try/catch unless the behavior requires it. Do not remove necessary error handling.
Verify the result.
- Run the narrowest relevant tests, lint, or typecheck for touched code when practical.
- If verification cannot run, say so explicitly.

Decision Rules

Prefer clarity over fewer lines.
Do not collapse separate concerns into one helper just to reduce repetition.
Stop simplifying when the next change would make debugging, extension, or review harder.
Keep the refactor local unless the user asks for a broader pass.
