# audit-verify-explain-grade-5

This skill makes the agent audit a change, back every claim with evidence, and then explain the result in plain language. Handy when you review someone else's fix or a test report.

## What it does

The skill splits every answer into three jobs: audit what changed, verify it with direct evidence, and explain it to a reader who is smart but new to the topic. The agent starts by finding the real source of truth — the diff, touched files, call sites, existing tests. Then it checks before and after behavior and separates measured results from guesses.

Verification follows a fixed order: automated tests, builds, linters and validators first, then running the actual app, then logs, screenshots and generated artifacts. Static code reading comes last, only when execution is impractical. When a check fails, the agent reports the blocker and what it means. When only part of the system was checked, it says so.

The skill forbids saying "everything works" unless the full workflow was tested. For performance work it keeps three claims apart: removing repeated work, should improve, and measured faster — the last one only with before and after numbers. The answer follows a short shape: what changed, why it matters, how it was verified, what is still not proven. Small answers get a paragraph instead of headings.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill audit-verify-explain-grade-5 -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/audit-verify-explain-grade-5/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/audit-verify-explain-grade-5/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill audit-verify-explain-grade-5 -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/audit-verify-explain-grade-5/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill audit-verify-explain-grade-5 -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/audit-verify-explain-grade-5/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MengTo/Skills audit-verify-explain-grade-5
```

2. **Manually: put the files in place**
- File: `.github/skills/audit-verify-explain-grade-5/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill audit-verify-explain-grade-5 -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MengTo/Skills --path agent-skills/codex/audit-verify-explain-grade-5
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/audit-verify-explain-grade-5/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill audit-verify-explain-grade-5 -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/MengTo/Skills/tree/HEAD/agent-skills/codex/audit-verify-explain-grade-5/SKILL.md

## When to use it
- audit a teammate's fix instead of trusting the summary
- separate measured speedups from hopeful claims
- explain a change to a non-technical stakeholder
- spot a regression at call sites of a changed function
- state clearly which parts were never verified

## Example prompts
- audit this fix and explain in plain words what changed
- run the tests and tell me what is actually proven and what is not
- compare before and after behavior and write a report for a non-technical reader

description: Audit work, verify claims with concrete evidence, and explain the result in simple grade-5 language.

# Audit, Verify, Explain

## Core Rule

Treat every answer as three jobs:

1. Audit what changed or what is being claimed.
2. Verify it with direct evidence.
3. Explain it like the reader is smart but new to the topic.

Do not skip verification when local files, commands, logs, tests, screenshots, or source data are available. Do not pretend something was verified if it was only inferred.

## Workflow

### 1. Audit

Start by finding the real source of truth:

- For code changes, inspect the diff, touched files, related call sites, and existing tests.
- For bug fixes, identify the before/after behavior and the user-facing path.
- For performance claims, separate measured evidence from likely improvement.
- For release or app behavior, check the packaged/running artifact when possible.
- For documents or content, compare the user request against the actual produced artifact.

Look for:

- obvious bugs or regressions
- missing edge cases
- stale assumptions
- unverified claims
- mismatches between implementation and user intent
- risks that a grade-5 explanation might accidentally hide

### 2. Verify

Prefer evidence in this order:

1. Automated tests, builds, linters, typechecks, or validators.
2. Running the actual app or workflow.
3. Logs, process checks, screenshots, generated artifacts, or live output.
4. Static code inspection when execution is impractical.
5. Clearly labeled inference when nothing stronger is available.

When verification fails, report the blocker and what it means. When verification is partial, say exactly what was and was not checked.

For performance work, avoid overclaiming. Say "this removes repeated work" only when the code clearly does so. Say "should improve" only when no timing trace was captured. Say "measured faster" only when before/after measurements exist.

### 3. Explain Simply

Use grade-5 language without talking down to the user:

- Use short sentences.
- Define technical terms in plain words.
- Use one simple analogy only if it genuinely helps.
