refactoring SKILL.md skillA

refactoring from fabiandistler/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add fabiandistler/agents/refactoring@v4.1

Pins v4.1 in mdr.lock. Pin the fingerprint instead.

Finds where refactoring is worth starting in an unfamiliar codebase by ranking files by git churn (hotspots) and explaining the ranking. Use when deciding which code to refactor first or where to start cleaning up a legacy repository.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Refactoring targets

One job: answer "where should we start?" with evidence instead of a guess.

## When to use

- The user asks which files or modules are worth refactoring first, where the
  hotspots are, or where to begin cleaning up a repo nobody in the conversation
  knows well.
- Not for: how to perform a particular refactoring (technique names and
  mechanics need no help), whether one module or dependency is healthy (that is
  `members/coupling-cohesion/SKILL.md`, read via the `architecture` router),
  staging a risky migration, or test-first development.

## Rank by churn, then read

The bundled script ranks files by their git history, the one source of
evidence every repo already has:

```
python3 <skills-dir>/refactoring/scripts/churn.py [path] [--since '12 months ago'] [--json]
```

`[path]` is the repository to rank (default: the current directory). The
same script is installed under your agent skills directory.
Because the script takes the target as an argument, the command works from
any working directory once installed.

Per file it reports commits in the window, distinct authors, current size,
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add fabiandistler/agents/refactoring@sha256:2025efb8bf027e81

The line at the top of this page pins the label v4.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
