What problem does it solve? Pull request reviews often miss real regressions or drown authors in subjective style comments. This Skill inspects the full diff, surrounding code, and relevant tests to surface only actionable defects with concrete triggers and consequences. ## Core Features & Use Cases - Defect-focused review: Traces callers, data shapes, error paths, and compatibility promises to find bugs with a concrete trigger and user-visible consequence. - ML and data reproducibility checks: Runs static reproducibility scans (e.g., Repro Lens) and bounded replays when the repository documents them, treating RNG, device, and data-order findings as review questions. - Structured findings output: Each finding includes a title, file and line, triggering conditions, consequence, and supporting evidence, with uncertainty labeled and style preferences kept separate. - Use Case: A maintainer asks for a review of a PR changing a training pipeline; the Skill reads the diff, runs the repository's declared replay command, and reports one actionable seed-handling defect with exact reproduction details. ## Quick Start Ask the assistant to review the current pull request for correctness regressions using its diff, surrounding code, and tests.
