## What it does

The skill identifies the project format from its instruction files. A `CLAUDE.md.spec.ts` or another `*.spec.ts` file marks a v2 setup, where rules use `enforce()`, `check()`, or `guidance()`. Without a spec file, it inspects v1 files such as `CLAUDE.md`, `AGENTS.md`, and `.cursorrules` for required annotations.

For v2, it runs `npx vigiles compile` and `npx vigiles discover`, checks whether enforcement entries match real linter rules, and flags checks that could move into the linter. For v1, it scans `###` headings and reports sections missing an enforcement marker.

The skill asks for approval before editing files. It then suggests either a linter-backed rule or guidance-only treatment, depending on what the project supports. Final validation uses `npx vigiles check`; v2 projects also run `npx vigiles compile`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add zernie/vigiles --skill enforce-rules-format -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add zernie/vigiles --skill enforce-rules-format -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add zernie/vigiles --skill enforce-rules-format -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install zernie/vigiles enforce-rules-format
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add zernie/vigiles --skill enforce-rules-format -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/zernie/vigiles --path .claude/skills/enforce-rules-format
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add zernie/vigiles --skill enforce-rules-format -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/zernie/vigiles/tree/HEAD/.claude/skills/enforce-rules-format/SKILL.md

## When to use it
- audit rule classifications in spec files
- find v1 rules that lack annotations
- match `enforce()` calls to linter rules
- spot checks that a linter could handle
- validate the result with `npx vigiles check`

## Example prompts
- Run the `enforce-rules-format` skill against this project.
- Inspect `CLAUDE.md.spec.ts`, `CLAUDE.md`, and `.cursorrules`, then report classification issues.
- Find rules that map to the linter and ask for my approval before editing files.

name: enforce-rules-format
description: Validate that all rules have proper enforcement classification (enforce/check/guidance)
disable-model-invocation: true
---

Validate that every rule in the project's instruction files has a proper enforcement classification, and fix any that are missing.

## Instructions

### Step 1: Detect Format

Check which format the project uses:

**v2 (spec-based):** Look for `CLAUDE.md.spec.ts` or any `*.spec.ts` files. If found, this is a v2 project — rules must use `enforce()`, `check()`, or `guidance()`.

**v1 (hand-written):** Look for `CLAUDE.md`, `AGENTS.md`, `.cursorrules`. If found without a spec file, this is a v1 project — rules need `**Enforced by:**` or `**Guidance only**` annotations.

### Step 2: Validate

**For v2 specs:**

The TypeScript type system already prevents unannotated rules — you can't create a rule without calling `enforce()`, `check()`, or `guidance()`. So focus on:

1. Do `enforce()` rules reference real linter rules? Run `npx vigiles compile` to check.
2. Are there guidance rules that COULD be `enforce()`? Check linter configs for matching rules.
3. Are there `check()` assertions that could be delegated to a linter? Suggest `enforce()` instead.

```bash
npx vigiles compile
npx vigiles discover
```

**For v1 hand-written files:**

Scan for `###` headings. Each must have one of:

- `**Enforced by:** \`linter/rule-name\``
- `**Guidance only** — reason`
- `<!-- vigiles-disable -->`

Report missing annotations with a summary table.

### Step 3: Fix Issues

For each issue found:

1. Check the project's linter configuration for matching rules
2. Suggest `enforce("linter/rule")` (v2) or `**Enforced by:** \`linter/rule\`` (v1)
3. If no linter rule exists, suggest `guidance()` (v2) or `**Guidance only**` (v1)
4. **Ask the user** before making changes

### Step 4: Suggest Migration

If the project uses v1 format, suggest migrating to v2 specs for type safety:

> Your rules could benefit from type-safe specs. Run the `adopt-spec` skill to convert your CLAUDE.md to a typed .spec.ts file.

### Step 5: Verify

Run the appropriate command:

```bash
# v2
npx vigiles compile && npx vigiles check

# validate
npx vigiles check
```

Report the validation result.
