## About

# TDD Refactor Phase Skill

## Purpose
- Improve code and test design after green
- Preserve all existing behavior
- Prioritize readability over forced deduplication
- Introduce helpers/builders when they improve future test authoring

## Inputs
- Commit details from commit stage (sha/message)
- Committed baseline
- Readability goals
- Project refactor patterns from `.github/instructions/tdd-patterns.instructions.md`
- Canonical REFACTOR style guide placeholder at `.github/skills/tdd-refactor/assets/project-refactor-patterns.md`

## Outputs
- Refactor diff
- Test pass evidence
- Helper/builder notes

## Steps
1. Load `.github/skills/tdd-refactor/assets/project-refactor-patterns.md` first, then load core asset files for refactor patterns, anti-patterns, and test readability
2. Inspect surrounding code around each in-scope change before refactoring
3. Refactor code and tests as needed
4. Use `tdd-test-run` with a `test_run_request` contract whose expected result is
  a passing validation for the touched slice, then the broader suite required
  by project policy
5. If the observed result does not match the expected REFACTOR outcome, revert
  only the scoped refactor changes and return to the pre-refactor baseline
6. Return contract output

## Completion Checks
- All behavior preserved
- Code and tests are more readable/maintainable
- Helpers/builders introduced only when justified
