### Description (declared)

Structured error knowledge database for AI coding agents. 2632 error patterns across 54 domains (android, api, aws, banking, cicd, cloud, cmake, communication, cuda, culture, data, database, disaster, docker, dotnet, elasticsearch, embedded, emergency, flutter, food-safety, git, go, grpc, huggingface, java, kafka, kubernetes, legal, llm, medical, mental-health, mongodb, networking, nextjs, nginx, node, opencv, pet-safety, php, pip, policy, python, pytorch, react, redis, ros2, rust, safety, security, tensorflow, terraform, typescript, unity, visa). Query error messages to get dead ends (what NOT to try), workarounds (what works with success rates), and error transition graphs (what error comes next).
