# Simplify Code Appendix

Extended examples and pattern notes live here to keep `SKILL.md` lean.

## Pattern Details

- Extract Method: split large functions into named units.
- Guard Clauses: replace deep nesting with early returns.
- Decompose Conditional: extract complex conditions and branches.
- Replace Magic Numbers: promote literals to named constants.
- Rename for Clarity: explicit, searchable, domain terms.
- Remove Dead Code: delete commented or unreachable code.
- Parameter Object: group related arguments when signatures are too long.

## Language-Specific Reminders

- JavaScript/TypeScript: prefer `const`, pure helpers, and array transforms.
- Python: prefer clear names, type hints where useful, and small functions.
- Java/C#: prefer focused classes and guard clauses.
- Go: keep functions small, explicit error paths.

## Anti-Patterns

- Large-bang rewrites
- Behavioral changes without explicit requirement
- Premature abstractions
- Clever code at cost of readability

## Suggested Validation Loop

1. Build/test baseline
2. Apply one simplification pass
3. Re-run build/tests
4. Repeat

If a pass introduces failures, stop and document in `simplification-report.md`.
