What problem does it solve? Reviews of code changes and documents are often shallow or inconsistent, missing edge cases, untested behavior, and structural problems. This Skill runs a disciplined multi-lens review over any diff, file, spec, or document and reports concrete findings in a canonical shape. ## Core Features & Use Cases - Multi-lens review: Ships adversarial, edge-case-hunter, verification-gap, structure, and prose lenses that run singly or together depending on content type. - Canonical findings output: Every finding carries location, trigger condition, guard snippet, and potential consequence, rendered as JSON, markdown, or both. - Customizable workflow: A customize.toml file lets teams add lenses, set style guides, define standing review guidance, and control output format and report destination. - Use Case: Ask for a critical review of a pull request diff; the edge-case lens enumerates unhandled branches while the verification-gap lens checks whether tests would actually catch a regression. ## Quick Start Ask the assistant to review a file or diff, for example: run a full review of the changes in src/scheduler.ps1 and report the findings.
