SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables safe, incremental refactoring with snapshot tests and git checkpoints.

Core Features & Use Cases

  • Incremental changes: Apply small, auditable edits with per-step validation.
  • Snapshot-based validation: Capture and compare behavior before and after changes.
  • Rollback readiness: Maintain git checkpoints to revert any step.

Quick Start

Start by creating a feature branch and document each step in DECISIONS.md. Then run the Step 1 tests, capture checkpoints, and proceed only after all tests pass.

Frequently Asked Questions about refactor

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I safely refactor code with git checkpoints and rollback?▼

Safe refactoring with git checkpoints involves creating a feature branch, applying incremental edits, capturing snapshot tests, and documenting decisions in DECISIONS.md to ensure every step is reversible.

What is incremental refactoring and how does snapshot validation work?▼

Incremental refactoring applies small, auditable code edits validated by snapshot tests that capture and compare software behavior before and after changes, ensuring no unintended side effects occur.

How do I structure a step-by-step refactoring plan with test-driven validation?▼

Start by branching in git, then execute the refactoring in small steps. Run Step 1 tests, capture checkpoints, document choices in DECISIONS.md, and proceed to the next step only after all tests pass.

Can I revert a specific code change if snapshot tests fail during refactoring?▼

Yes, rollback readiness is maintained through git checkpoints, allowing you to revert any specific incremental refactoring step where snapshot validation fails or unexpected behavior is detected.

Does this incremental refactoring approach require a DECISIONS.md file?▼

Yes, DECISIONS.md documentation is enforced to maintain traceable decisions during refactoring, ensuring every incremental change and its rationale is recorded for disciplined change management.

What's the best way to manage software refactoring for projects needing disciplined change management?▼

The best approach is incremental refactoring with per-step verification, using snapshot tests for behavior validation and git checkpoints for rollback readiness to guarantee safe, traceable code transformations.
