    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.

refactor — Refactoring Skill

Prime directive: Never change observable behavior. If a change would alter behavior, flag it and ask.

Execution Steps

  1. Read target and understand the current implementation.
  2. Check context — run git diff HEAD to understand recent changes.
  3. If --goal provided — focus all refactoring toward that specific goal.
  4. Identify opportunities:
    • Duplicated logic that could be extracted into shared functions
    • Functions longer than 40 lines doing more than one thing
    • Unclear names (variables, functions, classes)
    • Missing abstractions for repeated patterns
    • Dead code, commented-out blocks
  5. Show diff first (unless --auto) — present proposed changes as a unified diff.
  6. Wait for approval unless --auto is set.
  7. Apply changes and verify the test suite if one exists.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
