# strengthen

Scans vigiles specs and swaps guidance() rules for enforce(), matching each one to a linter rule that already exists. Useful when written conventions should fail CI on their own.

## What it does

The skill walks every `.spec.ts` file in the project and looks for `guidance()` rules. It runs `npx vigiles generate types`, reads `.vigiles/generated.d.ts`, and checks the rule text against the rules already enabled for ESLint, Ruff, Clippy, Pylint, RuboCop or Stylelint. A hit on the rule name, the meaning or the description is a direct swap — no config edit involved.

When nothing matches on the fast path, the skill reads the linter reference docs and looks for workarounds: a rule from an installed but disabled plugin, a plugin that is not installed yet, or a `no-restricted-*` pattern. Blocking imports from internal modules maps to `no-restricted-imports`; banning `console.log` maps to `no-restricted-syntax`. Those edits touch linter config, so the skill shows the exact file and section and waits for your call.

Before it starts, the skill asks which mode you want. Auto applies the safe swaps and commits them, leaving anything risky in a summary; interactive presents each suggestion one at a time. Interactive is the default. The split is about cost, not strictness: a free and reversible swap happens on its own, while a plugin install or a config change is yours to approve. Rules with no linter equivalent stay as guidance.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install zernie/vigiles strengthen
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/zernie/vigiles --path skills/strengthen
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add zernie/vigiles --skill strengthen -a opencode
```

### Claude.ai

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

## When to use it
- match linter rules to prose conventions in a spec
- swap guidance() for enforce() without touching linter config
- express a ban on an import or a call through no-restricted-*
- confirm the spec still compiles after each replacement
- separate safe swaps from ones that need a plugin install

## Example prompts
- scan the specs and tell me which guidance() rules I can turn into enforce()
- harden the rules in my CLAUDE.md spec where the linter rule is already on
- show me what I'd need to install to cover the remaining guidance() rules

```text

name: strengthen
allowed-tools: Read, Edit, Write, Glob, Grep, Bash
description: Upgrade a vigiles spec's guidance() rules to enforce() — scan the guidance rules in a CLAUDE.md/AGENTS.md spec and find existing linter rules (ESLint, Ruff, Clippy, Pylint, RuboCop, Stylelint) that back them. Use when asked to strengthen, harden, or make vigiles rules enforceable; NOT for general linting or fixing lint errors.
---

Scan spec files for `guidance()` rules and suggest `enforce()` replacements backed by real linter rules.

## Principle: auto the free wins, nudge for the costs

The dividing line is **cost, not strictness**. A `guidance()` → `enforce()` swap where the linter rule **already exists and is enabled** is a pure win — free, reversible, no false-positive risk — so apply it (Tier 1 below). Anything that **costs** something — editing linter config, installing a plugin, or a change that could fail a clean CI — is the user's call: **present it with the tradeoff spelled out and let them choose** (Tiers 2–4). Never silently edit config, install a dependency, or escalate the repo into strict gating. This is the `init` enforcement model (structural = on by default, workflow/strict = opt-in) applied at edit time.

## Instructions

### Step 0: Choose Mode

Ask the user:

> **Auto or interactive?**
>
> - **Auto** — I'll apply all safe changes (direct replacements where the rule is already enabled), commit, and show you the diff. Risky changes (require config edits or plugin installs) go in a summary for you to review.
> - **Interactive** — I'll present each suggestion and you pick which ones to apply.

Default to interactive if the user doesn't specify.

### Step 1: Discover What's Installed

Run `npx vigiles generate types` to get the full list of enabled linter rules in the project. Read `.vigiles/generated.d.ts` to see every rule available across all detected linters.

Note which linter prefixes appear in the generated types (e.g., `EslintRule`, `RuffRule`). You'll only need reference docs for detected linters.

### Step 2: Find All Guidance Rules

Find all `.spec.ts` files in the project (`**/*.md.spec.ts`). For each file, identify every `guidance()` rule.

### Step 3: Match Against Generated Types (Fast Path)

For each guidance rule, check if an enabled rule in `.vigiles/generated.d.ts` directly matches. This is the fast, deterministic path — no doc reading needed.

Look for:

- **Exact rule name in text** — guidance says "no-console" and `no-console` is in EslintRule
```
