## What it does

The server gives an AI assistant findings about a codebase, including complex logic, debt markers such as `TODO` and `FIXME`, and unfinished implementations. Stub detection uses tree-sitter AST analysis rather than matching keywords in text, so trigger words inside string literals are not treated as stubs.

Stub checks can run in CI: `omen stubs --gate error` makes the check fail when stubs are found. A severity threshold is configurable. The documented launch uses Docker and the image `ghcr.io/panbanda/omen:3.0.0`. MCP setup commands are provided for Claude Code, Codex, and Gemini CLI; Cursor uses a configuration entry.

## Requirements
- Needs: Docker

## Install

}
```

### Gemini CLI

**Platform CLI**
```bash
gemini mcp add omen docker run -i --rm ghcr.io/panbanda/omen:3.0.0
```

## When to use it
- identify functions with complex logic
- collect comments that flag debt, bugs, or missing requirements
- find unfinished implementations in a codebase
- fail CI when stub code is detected

## Example prompts
- Analyze this repository and show the areas with complex logic.
- Find unfinished implementations and group them by severity.
- Check the code for `TODO`, `FIXME`, and `SECURITY` comments.
