Refactor
Objective
- •Simplify and clarify code while keeping behavior identical.
- •Reduce technical debt in-scope without altering APIs or outputs.
When to use
- •Behavior is correct but code quality is poor.
- •There is approval to clean up without feature changes.
Inputs
- •User intent and acceptance for refactor scope.
- •AGENTS.md, rules, and relevant code/tests.
- •Existing tests to confirm behavior stability.
Process
- •Identify pain points (duplication, naming, structure).
- •Plan minimal, safe refactors; avoid tangents.
- •Apply changes incrementally, keeping tests passing.
- •Verify behavior parity via tests or reasoning.
- •Note any residual debt deferred.
Outputs
- •Files changed and rationale.
- •Confirmation of unchanged behavior.
- •Tests run (or why not) to prove parity.
Edge cases
- •If behavior must change, switch to implement/optimize.
- •Avoid large extractions without clear gain and approval.
