Change Risk Radar is a local-only dev tool that analyzes code diffs when you make a git commit to calculate the "blast radius" and potential risks of your changes before you push. Key features include: Automated Workflow: Uses a git pre-commit hook to send diffs to a local orchestrator, automatically opening a dashboard with the results. Multi-Agent Analysis: Runs 4 parallel specialized agents (Code Impact, Dependency, Test Intelligence, and History) alongside a 5th agent (Risk Card Composer) to synthesize findings. Grounded & Verified Claims: Uses AST-based static call graphs, git history, and filesystem checks to verify claims and prevent LLM hallucinations. Python Focus: Primary ground-truth call graph features are built for Python codebases.
