This repository is a curated, open-source catalog of AI agent design patterns. It functions primarily as a documentation website (built with Astro, deployed to Vercel) that indexes ~200+ patterns across categories like orchestration, memory, security, and tool use. Patterns follow a strict template with YAML frontmatter, evidence grading, and cross-references. The codebase includes a static site generator, automated research pipelines (arXiv scanning, similarity checking), and CI/CD for pattern validation. While the core deliverable is a web application, the repository also contains significant research infrastructure (scripts for paper discovery, reference verification, and pattern quality fixing), making it a hybrid between an application and a research data project. The source of truth is markdown files in `patterns/`; the build pipeline generates JSON, graph data, and site assets. The project is actively maintained with community contribution guidelines and automated PR review workflows.
