## What it does

The skill audits a working diff, branch, or specified commit range. Rather than issuing a merge approval, it compiles evidence-backed findings categorized into blocker, high, medium, and low severity tiers. The review inspects areas like security, correctness, specs, telemetry, deslop, and complexity.

Execution relies on bundled helpers run with `age.pyz` under Python. It invokes `review-lock` to freeze the inspection packet before reading context. Modifying tracked production files while the review runs causes the process to reject the final report.

Responsibilities remain strictly separated. The skill refuses to apply fixes or harden test suites directly. Discovered issues route to `/cure`, while testing tasks belong to `/press`. Passing the `--html` flag outputs an offline HTML report that requires neither JavaScript nor CDNs.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill age -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill age -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill age -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install paulnsorensen/easy-cheese age
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill age -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/paulnsorensen/easy-cheese --path skills/age
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill age -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/paulnsorensen/easy-cheese/tree/HEAD/skills/age/SKILL.md

## When to use it
- review working diffs before merging a pull request
- catch security flaws and correctness bugs early
- sort code issues into structured severity groups
- prepare an actionable report for the `/cure` skill

## Example prompts
- Review this PR using `/age`
- \`/age main..HEAD --effort deep`
- Check for bugs and security issues in this branch with `/age`

  Review a diff, PR, branch, or path across thirteen dimensions. Emit a severity-grouped findings report.
  Use when the user wants a code review. Trigger on "review this", "/age", "is this safe to merge", or "find bugs".
  Also trigger on "spot security issues", "check for slop", "review my PR", or "what's wrong with this code".
  Review every requested dimension. Review all thirteen dimensions by default.
  Do not apply fixes. Route them to /cure.
  Do not harden tests; route that work to /press.

# /age

Review a diff or scoped path before merging or after `/press`. Use this skill whenever the user wants evidence-backed observations rather than an approval verdict.

## Phase entry

Run `python3 skills/age/scripts/age.pyz wheypoint-resolve --ref <slug>`.
`authoritative` uses the record; its `working_context` is the first batched `tilth_read`.
`not-found` proceeds cold; `legacy` shows its source and slug, then proceeds.
`gated`, `ambiguous`, and `error` stop and show the payload.
Show advisory `stale-commit` and `grounded-path-missing` findings.
Keep its `record.revision_id` as `<base>` ([§ Base revision](../cheese/references/handback-contract.md#base-revision)).

## Inputs

```text
/age [<ref-or-range>] [--scope <path>]... [--slug <slug>] [--effort quick|normal|deep] [--overall] [--full] [--safe] [--open-pr] [--auto] [--hard] [--html]
/age <slug> [--effort quick|normal|deep] [--overall] [--full] [--safe] [--open-pr] [--auto] [--hard] [--html]
```

Repeat `--scope <path>` for each reviewed path.
Every report needs a slug.
Take the slug from the `<slug>` form.
Take it from `--slug <slug>` on a scoped or range review.
Derive it with `slugify` only when the caller supplies neither.
A caller in a pipeline always passes the pipeline slug.

`--full` expands the `## Low` section when ten or more low-severity findings exist.
The default report collapses that section to a one-line summary.

`--safe` re-introduces cure selection.
`--open-pr` propagates through `/cure` to terminal `/plate`.
A new PR follows `/plate`'s explicit-choice and review-shape policy.

After phase entry, use `.cheese/press/<slug>.md` (if present) as Press context.

Review the current working diff.
For a `<ref-or-range>`, review that range.
Review the current working diff when the user supplies neither input.
If the base branch is unclear, ask or use the repository's documented default.

`--auto` is the propagated autonomous-mode flag from `/cook --auto`.
See `## Handoff` and `references/handoff-detail.md` § Auto mode for the cap rule and the full chain.

`handoff_context.wiki_hits` is optional routed input from `/cheese`.
Each hit carries `page`, `line`, and `why`.
Reuse each valid hit before you ground the review again.
Render the reused hits in `## Wiki context`.

`--hard` propagates through `/cure` to `/plate`.
Age never fires the gate.
`/plate` gives `/hard-cheese` the final verified artifact state before publication.

`--html` emits a static HTML copy alongside `.cheese/age/<slug>.md`.
Write the markdown first.
