## What it does

The skill walks your route definitions, pulls out methods, paths, params and request bodies, then builds a collection for Bruno, the open-source API client that keeps requests as plain text and plays well with Git. You get a `bruno.json` manifest, folders grouped by resource with a `folder.bru` inside each, and a separate `.bru` file per request.

The workflow is spelled out step by step: scan routes, extract metadata, initialize the collection, generate files, group by resource, add environments. Development, Staging and Production come out of the box, each with its own `baseUrl`. Auth covers bearer, basic and apikey, with the token passed as `{{authToken}}`. There is also a TypeScript generator at `scripts/generate-bruno.ts` if you would rather run the whole thing programmatically.

That script expects Node.js, since it writes files through `fs` and `path`. Routes declared in an unusual way may not parse cleanly, so expect to fix a few files by hand.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill bruno-collection-generator -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill bruno-collection-generator -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill bruno-collection-generator -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install patricio0312rev/skills bruno-collection-generator
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill bruno-collection-generator -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/patricio0312rev/skills --path testing/bruno-collection-generator
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add patricio0312rev/skills --skill bruno-collection-generator -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/patricio0312rev/skills/tree/HEAD/testing/bruno-collection-generator/SKILL.md

## When to use it
- turn existing API routes into a Bruno collection
- group requests into resource folders instead of one flat list
- set up Development, Staging and Production environments with separate baseUrl values
- apply bearer auth across every protected request
- generate .bru files from a TypeScript script

## Example prompts
- generate a bruno collection from this project's routes
- create .bru files for all users and auth endpoints
- add Development, Staging and Production environments to the Bruno collection

description: Generates Bruno collection files (.bru) from Express, Next.js, Fastify, or other API routes. Creates organized collections with environments, authentication, and folder structure for the open-source Bruno API client. Use when users request "generate bruno collection", "bruno api testing", "create bru files", or "bruno import".

# Bruno Collection Generator

Generate Bruno collection files for the open-source, Git-friendly API client.

## Core Workflow

1. **Scan routes**: Find all API route definitions
2. **Extract metadata**: Methods, paths, params, bodies
3. **Create collection**: Initialize bruno.json manifest
4. **Generate .bru files**: One file per request
5. **Organize folders**: Group by resource
6. **Add environments**: Dev, staging, production

## Bruno Collection Structure

```
collection/
├── bruno.json              # Collection manifest
├── environments/
│   ├── Development.bru
│   ├── Staging.bru
│   └── Production.bru
├── users/
│   ├── folder.bru
│   ├── get-users.bru
│   ├── get-user.bru
│   ├── create-user.bru
│   ├── update-user.bru
│   └── delete-user.bru
├── auth/
│   ├── folder.bru
│   ├── login.bru
│   ├── register.bru
│   └── logout.bru
└── products/
    ├── folder.bru
    └── ...
```

## bruno.json Manifest

```json
{
  "version": "1",
  "name": "My API",
  "type": "collection",
  "ignore": ["node_modules", ".git"]
}
```

## .bru File Syntax

```bru
meta {
  name: Get Users
  type: http
  seq: 1
}

get {
  url: {{baseUrl}}/users
  body: none
  auth: bearer
}

auth:bearer {
  token: {{authToken}}
}

query {
  page: 1
  limit: 10
}

headers {
  Accept: application/json
}

docs {
  Retrieve a paginated list of users.
}
```

## Generator Script

```typescript
// scripts/generate-bruno.ts
import * as fs from "fs";
import * as path from "path";

interface RouteInfo {
  method: string;
  path: string;
  name: string;
  description?: string;
  body?: object;
  queryParams?: { name: string; value: string }[];
  auth?: boolean;
}

interface BrunoOptions {
  collectionName: string;
  outputDir: string;
  baseUrl: string;
  authType?: "bearer" | "basic" | "apikey";
}

function generateBrunoCollection(
  routes: RouteInfo[],
  options: BrunoOptions
): void {
  const { outputDir, collectionName } = options;

  // Create output directory
  if (!fs.existsSync(outputDir)) {
