# edit-spec

Edits vigiles .spec.ts files to compile CLAUDE.md and AGENTS.md instructions. Keeps agent rules, sections, and commands updated without modifying build artifacts directly.

## What it does

The skill edits root specification files such as `CLAUDE.md.spec.ts` and `AGENTS.md.spec.ts`. These TypeScript files serve as the single source of truth for repository instructions. The resulting `CLAUDE.md` and `AGENTS.md` files carry vigiles verification hashes. Editing compiled artifacts directly is counterproductive, since any recompile immediately overwrites manual changes.

Incoming rules get sorted into three distinct types. Linter-backed rules for tools like ESLint or Ruff become `enforce()` calls. File presence assertions use `check()`. Process advice without mechanical enforcement falls back to `guidance()`. The tool also manages document sections and registers scripts in the `commands` map, verifying them against `package.json`.

The deprecated `keyFiles` field is strictly avoided. When pointing to a specific file, the skill places context in file header comments, nested instructions, or a verified `${file()}` interpolation. Once changes are saved, it runs `npx vigiles compile` and `npx vigiles lint` to validate the updated instruction set.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install zernie/vigiles edit-spec
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add zernie/vigiles --skill edit-spec -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/skills/edit-spec/SKILL.md

## When to use it
- add an enforce() rule connected to an active project linter
- update architecture and overview prose sections in spec.ts
- register verified scripts from package.json in agent commands
- set up check() filesystem assertions for paired project files
- replace deprecated keyFiles entries with verified file references

## Example prompts
- Add an enforce rule to CLAUDE.md.spec.ts disallowing console.log via ESLint
- Update the architecture section in spec.ts and add a reference to src/services/auth.ts
- Add npm run lint to the commands block in the spec

name: edit-spec
allowed-tools: Read, Edit, Write, Glob, Grep, Bash
description: Edit a vigiles .spec.ts to change a compiled instruction file (CLAUDE.md / AGENTS.md) — add, modify, or remove a rule, section, command, or file pointer (including a request to add a "key file" — the keyFiles field is deprecated). Use whenever you need to change a CLAUDE.md/AGENTS.md that carries a vigiles hash (edit the spec, never the artifact), including adding a new enforce()/check()/guidance() rule.
argument-hint: <what to change — e.g., "add a rule about error handling" or "update the testing section">
---

Edit a `.spec.ts` file to update the project's instruction files. The spec is the source of truth — CLAUDE.md and AGENTS.md are compiled build artifacts that must not be edited directly.

## Arguments

$ARGUMENTS — What the user wants to change. Examples:

- "add a rule about always using the custom logger"
- "update the architecture section"
- "point the auth rule at src/services/auth.ts"
- "add npm run lint to commands"
- "change the testing guidance"

## Instructions

### Step 1: Find the Spec

Look for spec files in the repo root:

- `CLAUDE.md.spec.ts` — source for CLAUDE.md
- `AGENTS.md.spec.ts` — source for AGENTS.md
- Any `*.spec.ts` matching instruction files

If no spec exists: if there's a hand-written `CLAUDE.md`, suggest the
`adopt-spec` skill; otherwise suggest `npx vigiles init` to scaffold one.

### Step 2: Read and Understand the Spec

Read the spec file. It's a TypeScript file that exports a `claude()` call with these fields:

```typescript
import { claude, enforce, guidance, check, every } from "vigiles/spec";

export default claude({
  // Optional: output target (defaults to "CLAUDE.md")
  target: "CLAUDE.md",
  // or multi-target:
  // target: ["CLAUDE.md", "AGENTS.md"],

  // Prose sections — become ## headings in compiled output
  sections: {
    positioning: "What this project does...",
    architecture: "How the codebase is structured...",
  },

  // (No `keyFiles` — deprecated; see "A pointer to a file" in Step 3.)

  // Commands verified against package.json
  commands: {
    "npm run build": "Compile the project",
    "npm test": "Run all tests",
  },

  // Rules — three types
  rules: {
    // enforce() — backed by a linter rule, verified to exist AND be enabled
    "no-any": enforce(
      "@typescript-eslint/no-explicit-any",
      "Use unknown and narrow with type guards.",
    ),

    // check() — filesystem assertion run by vigiles
    "test-pairing": check(
      every("src/**/*.service.ts").has("{name}.test.ts"),
      "Every service must have tests.",
    ),

    // guidance() — prose only, no enforcement
````

The third-party file has ended. Everything between the 66dd563603c1a912 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
