What problem does it solve? Document review in multi-agent workflows often produces inconsistent, overlapping, or unscoped feedback. This Skill enforces a single-focus review discipline: one reviewer, one persona, one artifact, one structured findings file, so orchestrators like validate-doc can fan out parallel reviews and triage-feedback can parse uniform output. ## Core Features & Use Cases - Focus-driven review: Resolves a focus brief (accuracy, architecture, clarity, comprehensiveness, depth, dx, integration, scope) that defines the persona, signals to flag, verification recipe, and severity calibration. - Persona adoption: Borrows the cognitive profile of a named persona agent (architect, qa, doc-writer, reviewer, researcher, dx) while keeping read-only tools. - Standardized output: Writes an rNN-{focus}.md file with fixed Blockers/Majors/Minors/Nits sections so downstream triage parses one shape. - Use Case: An orchestrator validating a plan chapter dispatches this Skill with focus=accuracy; it verifies every external claim against primary sources at the pinned version and writes r03-accuracy.md next to the chapter. ## Quick Start Dispatch this skill with a focus name, the artifact path, the target rNN filename, and an iteration number to produce a single-focus review file alongside the artifact.
