Petamind

Agentic coding loop with multi-candidate patch generation, deterministic quality gates, and vision-based UI evaluation using Playwright screenshots.

Petamind is an agentic coding loop MCP server that generates, tests, and visually evaluates code modifications. It provides multi-candidate patch generation with deterministic gates, integrating quality checks including accessibility testing via axe-core and performance benchmarks via Lighthouse. The system uses Playwright for screenshot capture and supports various LLM providers (Vertex AI, OpenRouter) for patch generation and vision-based assessment of UI changes.
