# audit

This skill reviews working code for structural issues and ranks findings by the cost of leaving them in place. Use it when planning a refactor and deciding which problems matter first.

## What it does

The review covers public functions and classes, names, imports, long functions, and tests. It looks for mixed responsibilities, stale names, dependencies that point toward infrastructure, diverged copies, and implicit state. Formatting and import order do not count as findings.

Findings should point to specific lines, appear in order of expected cost, and explain the structural problem before suggesting a small fix. The skill also asks the reviewer to say which areas were checked and left alone, with a reason. It focuses on code structure, not whether business rules are correct; a long function alone is not enough to flag it.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add rainmanjam/poka-yoke --skill audit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/audit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/audit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add rainmanjam/poka-yoke --skill audit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/audit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add rainmanjam/poka-yoke --skill audit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/audit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install rainmanjam/poka-yoke audit
```

2. **Manually: put the files in place**
- File: `.github/skills/audit/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add rainmanjam/poka-yoke --skill audit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/rainmanjam/poka-yoke --path benchmarks/controls/clean-code/skills/audit
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/audit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add rainmanjam/poka-yoke --skill audit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/rainmanjam/poka-yoke/tree/HEAD/benchmarks/controls/clean-code/skills/audit/SKILL.md

## When to use it
- spot functions that combine unrelated responsibilities
- catch names that no longer match their implementation
- find business logic tied to infrastructure
- identify which diverged copy should be treated as correct
- rank structural findings by the cost of leaving them

## Example prompts
- Review this code's structure and report significant issues with line references.
- Find copies of the same logic that have drifted, and say which one is correct.
- Check dependency direction and testability, then suggest the smallest useful changes.

# Audit: Reading Code That Already Works

Everything you are looking at ships and passes its tests. That is the constraint. You are not
hunting for bugs; you are finding the places where the structure will make the *next* change
expensive or risky, and saying which ones are worth paying to fix now.

That framing matters, because a review that lists everything imperfect is indistinguishable
from a review that found nothing important.

## Read in this order

**1. The public surface.** Exported functions, classes and endpoints. This is what other code
depends on, so problems here have the largest blast radius and the highest migration cost.

**2. The names.** Read them without reading the bodies. Any name that turns out to be wrong
once you read the implementation is a finding, because every future reader will make the same
mistake you just did.

**3. The imports.** They show the dependency direction at a glance. Business logic importing a
web framework, an ORM or a mail client is the single most reliable structural smell.

**4. The longest functions.** Not because length is the problem, but because that is where
several responsibilities usually ended up together.

**5. The tests.** Tests are a readout of the design. Heavy mocking means tangled dependencies.
Long setup means complicated construction. Absent tests for the core logic usually means the
core logic is hard to reach.

## What to look for

**Responsibilities that drifted together.** Describe the unit in one sentence. If you need
"and", note where the seam is: which parts change for different reasons, and on whose schedule.

**Names that have gone stale.** A function called `validate_user` that also creates a session.
A `TempFile` class that outlives the request. A `config` parameter that is actually a feature
flag. The code changed, the name did not, and the name is what the next reader trusts.

**Dependency direction.** Which module could not be tested, reused or moved without dragging
something heavy behind it? That is coupling with a cost you can name.

**Duplication that has diverged.** Two copies that started identical and have drifted are worse
than either one alone, because a fix applied to one leaves the other wrong. Note which is
correct.

**Ambient state.** Module-level singletons, globals, and implicit context. Each makes a unit's
behaviour depend on something not visible at its call site.

**Boolean parameters at call sites.** `render(rows, True, False)` cannot be read. Note it where
the call sites are numerous enough for the confusion to be real.

**Comments explaining what the code does.** Usually a sign the code does not say it. The
comment is not the finding; what forced it is.

## Ranking, which is most of the value

An unordered list of twenty observations moves nothing. Rank by expected cost of leaving it,
