How to build a Google Antigravity Agent That Fixes Failing CI with CopilotKit

Repo Doctor is a tutorial application that combines Google’s Antigravity agent platform, its AG-UI streaming adapter, and CopilotKit to diagnose and repair failing GitHub Actions CI workflows through an interactive web interface. Powered by Gemini, the agent clones a repository into an isolated workspace, examines CI results, installs dependencies, reproduces failures locally, edits code, displays diffs and test-result cards, verifies that the originally failing check passes, and creates a local fix branch without pushing changes to GitHub. Antigravity supplies built-in file, shell, web-search, and custom Python tool capabilities, while AG-UI streams model output, tool activity, shared state, and approval interruptions to a Next.js frontend backed by FastAPI. Users can approve or deny potentially risky operations such as installs, edits, shell commands, and pushes, while CopilotKit renders tool-specific UI, A2UI test-report components, a live side panel, and downloadable run reports. CopilotKit Intelligence can persist conversations across devices and provide usage and reliability analytics, while the complete application can run locally or as a private single-instance Google Cloud Run service with secrets in Secret Manager and per-conversation workspaces preserved in Cloud Storage.
