refactor

Skill4 starsChanged 4 months agoMITView on GitHub

Deterministic refactor workflow with tests as the safety net — analyze → plan → refactor → run-tests → fix-tests → comparison. The workflow will not exit until tests pass, guaranteeing behavior preservation. Use when the user asks to "refactor", "restructure", "reorganize", "clean up", "extract", "rename across files", or "modernize" existing code that has test coverage. Worth the ceremony when — the refactor spans multiple files, behavior must be preserved exactly, test coverage exists to prove nothing broke, or the user explicitly wants a safety-netted transformation. Do NOT use for renaming a single variable or function in one file (just do it — the workflow overhead isn't worth it). Do NOT use for adding new behavior (use feature) or fixing broken behavior (use bugfix). Do NOT use when there are no tests — the safety net is the entire point; without tests, do the refactor manually with careful review. If the user wants refactoring advice or a discussion (not the transformation), answer directly instead of dispatching the workflow.

    ascii-diagram

    Generate perfectly aligned ASCII diagrams — architecture, flow, sequence, box-and-arrow. Uses a programmatic character-grid approach so alignment is guaranteed by math, not token prediction. Includes post-render verification.

The file

We split this skill into the rules it gives an agent

1 rule. 0 are common, 0 are distinctive, and 1 is very specific to this project.

  • 0

    Common

    Most of the 168 edited versions we read keep these.

  • 0

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Use the devkit_start tool with workflow: "refactor" and input: "{input}".

    line 12

“Common” is measured: kept by at least 6 in 10 of the 168 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Refactor

Deterministic refactor workflow. Analyze → plan → refactor → run-tests → fix-tests → comparison. Tests are the safety net — the workflow will not exit until they pass.

Invoke

Use the devkit_start tool with workflow: "refactor" and input: "{input}".

Then follow each step the engine returns. Call devkit_advance after completing each step. The engine controls step order, gates, and loops. Do NOT skip steps.
