Field notes
The project offers three operating paths: an agent skill, a GitHub App, and a CI Action. Its example frames 400 changed lines across 12 files as a single animated diagram, while the renderer produces SVGs through a bespoke system rather than Mermaid. The homepage says the App uses Gemini by default; the Action can instead use a supplied Gemini, OpenAI, or compatible endpoint key.
