Static analysis is good at finding problems and bad at getting them fixed. Code Healer closes that gap.
It is a nine-node LangGraph workflow: it reads SonarQube issues, generates a fix plan with a confidence score for each one, applies the fixes, and opens a GitLab merge request. The merge request is deliberate: a human review stays the checkpoint, so nothing reaches the main branch on the agent’s say-so.
It won the hackathon it was built for, and runs at roughly $0.23 per run on LangGraph and AWS Bedrock.
