What are characterization tests in this context?

These are tests that 'pin' the current behavior of the code by snapshotting outputs. They must pass both before and after the refactor to prove no regressions occurred.

How does it integrate with my project configuration?

It uses a .rawgentic.json config file to detect your testing frameworks, CI/CD providers, and project boundaries, ensuring the workflow respects your specific stack.

How does the skill handle different types of refactoring?

It classifies tasks into four categories (Rename, Extract, Restructure, Simplify), each with specific risk assessments, critique depths, and complexity budgets.

Does this skill add new features to my code?

No. This skill is strictly for refactoring. If the scope requires a change in behavior, it will prompt you to switch to a feature implementation workflow instead.

What is the behavioral preservation invariant?

It is a strict rule enforced by the skill that ensures external behavior—such as API contracts, database schemas, and CLI interfaces—remains exactly the same after the refactor.

开发者工具

Refactors complex codebases using a rigorous 14-step workflow that guarantees behavioral preservation through characterization testing.

The Rawgentic Refactor skill implements the WF4 workflow, a structured engineering protocol designed for safe, high-integrity code transformations. It moves beyond simple search-and-replace by enforcing a 'behavioral preservation invariant,' requiring characterization tests to snapshot current outputs before any changes occur. The skill automatically classifies refactoring tasks into Rename, Extract, Restructure, or Simplify categories, applying tailored critique levels and loopback budgets to ensure structural improvements never compromise existing functionality or API contracts.
