What problem does it solve? Code reviews often miss breakage that grep and symbol searches cannot show, such as changes to wire formats, DB columns, feature flags, or downstream consumers. This Skill finds the hidden impact of a change before it ships and replaces convincing-sounding writeups with proof from actually running the code. ## Core Features & Use Cases - Hidden Impact Analysis: Traces risks that static search misses, including API responses, data formats, cross-language consumers, and code several hops downstream. - Evidence-Based Verification: Ranks each safety claim on a five-step confidence ladder, from assertion up to reproduction in the running app, and requires a script or test for the key fact. - Structured Risk Report: Returns what changed, the one fact the change is safe because of, confirmed risks with file:line citations, cleared concerns, and the cheapest pre-merge test. - Use Case: Before merging a small diff you do not trust, ask for its blast radius and receive a proven or explicitly unproven safety claim backed by a runnable script. ## Quick Start Ask the assistant to analyze the blast radius of your current diff and prove the one fact it is safe because of by running real code.
