Could you build this?
Partial Integrating with GitHub and generating an LLM summary is easy, but a useful risk map needs real code-impact analysis and a risk model that is accurate enough for approvers to trust.
What it would actually take: The stack would be a GitHub App that pulls PR diffs and history, static analysis or dependency and call-graph analysis for blast radius, and an LLM layer to explain risk. The hard part is calibrating risk signals (churn, ownership, test coverage, sensitive paths) so the output is actionable rather than noisy. That requires repository-scale analysis skill and feedback from real reviewers.
