## What it does

The skill handles EventCatalog documentation directly inside your coding agent. It checks whether a catalog already exists by scanning for `eventcatalog.config.js` or standard folders. If you start from scratch, it scaffolds an empty project via `npx @eventcatalog/create-eventcatalog@latest <name> --empty`. It also detects whether your repository relies on flat folders or nested domain trees.

You can point the agent at an application codebase to discover services, queues, and message schemas. It supports JSON Schema and Avro alongside Mermaid diagrams. When the EventCatalog MCP server is connected, the skill queries `getResources`, `getResource`, `findResourcesByOwner`, and `getSchemaForResource`. Because of this, newly generated files follow your existing naming conventions and team ownership.

Generated Markdown files are written straight into your catalog directory instead of staying in the chat output. Every resource file includes valid YAML frontmatter with required `id`, `name`, and version properties.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add event-catalog/skills --skill catalog-documentation-creator -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add event-catalog/skills --skill catalog-documentation-creator -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add event-catalog/skills --skill catalog-documentation-creator -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install event-catalog/skills catalog-documentation-creator
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add event-catalog/skills --skill catalog-documentation-creator -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/event-catalog/skills --path skills/catalog-documentation-creator
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add event-catalog/skills --skill catalog-documentation-creator -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/event-catalog/skills/tree/HEAD/skills/catalog-documentation-creator/SKILL.md

## When to use it
- document microservices, events, and queries for EventCatalog
- scaffold an empty EventCatalog workspace from the CLI
- record architecture decision records (ADRs) linked to components
- describe message channels like Kafka or RabbitMQ with payload schemas
- extract system domains and aggregate entities from application code

## Example prompts
- Document our payment microservice and its emitted events in the catalog
- Create an ADR for switching our primary broker to RabbitMQ
- Scaffold a new EventCatalog project in ./docs/catalog and add our core domain entities

# EventCatalog Documentation Creator

Generate properly formatted EventCatalog documentation files following project conventions and best practices.

## Instructions

### Step 1: Locate or Create the User's Catalog

Before generating any files, ask the user: **"Do you already have an EventCatalog project, or would you like to create a new one?"**

**If they already have a catalog:**
- Ask: **"Where is your EventCatalog project?"** — It could be:
  - A repo they've cloned locally (e.g., `~/projects/my-catalog/`)
  - A folder on their machine
  - A monorepo with the catalog in a subdirectory
- Verify it looks like an EventCatalog project by checking for an `eventcatalog.config.js` file or known directories (`systems/`, `services/`, `agents/`, `events/`, `domains/`, `adrs/`, `data-products/`, `entities/`, etc.)
- Read the existing structure to understand whether they use **nested** (domains/services/agents/events) or **flat** (top-level services/, agents/, events/) organization

**If they don't have a catalog yet:**
- Ask where they'd like to create it (default: current directory)
- Run the following command to scaffold a new empty catalog:
  ```bash
  npx @eventcatalog/create-eventcatalog@latest my-catalog --empty
  ```
  (Replace `my-catalog` with the user's preferred name)
- This creates a ready-to-use EventCatalog project with the correct structure
- All generated documentation files go inside this new catalog directory

CRITICAL: All generated files must be written to the user's catalog directory, not just displayed. Always ask where they want resources documented — never assume.
