Names several input types (diffs, PRs, specs, plans, review-feedback items) and describes the output (severity-ranked engineering findings with exact locations), but the actions themselves are somewhat vague—'review' is broad and the specific concrete operations beyond ranking are not enumerated.

Clearly answers both 'what' (review diffs/PRs/specs/plans and return severity-ranked findings with exact locations) and 'when' (use when technical risks or feedback correctness must be verified before implementation), with an explicit 'Use when' clause.

Includes some relevant terms like 'diffs', 'PRs', 'specs', 'review-feedback', and 'technical risks', but misses common natural variations users might say such as 'code review', 'pull request', 'design review', 'audit', or 'check for bugs'. The phrase 'feedback correctness must be verified' is somewhat unnatural.

The scope is fairly broad—reviewing diffs, PRs, specs, and plans could overlap with general code review skills, PR summary skills, or architecture review skills. The 'severity-ranked findings with exact locations' output format adds some distinctiveness, but the wide input range increases conflict risk.

The skill is reasonably structured but includes some unnecessary verbosity—e.g., the 'Philosophy' section is two lines that restate what the procedure already implies, the 'Examples' section lists natural-language prompts rather than adding technical value, and some sections like 'Anti-Patterns' could be tighter. However, it doesn't over-explain concepts Claude already knows.

The procedure provides a numbered sequence of steps but they are abstract and descriptive rather than concrete—no executable commands, no code snippets, no specific tool invocations, no structured output template. The outputs section mentions a schema but doesn't show it. Findings severity levels (P0-P3) are mentioned but not defined. The guidance tells Claude what to do conceptually but not how to do it concretely.

The procedure has a clear 6-step sequence and the validation section adds checkpoint-like criteria. However, the validation steps are described as assertions rather than actionable checkpoints integrated into the workflow. The 'fail fast' instruction is mentioned but not tied to specific steps. For a review skill involving potentially destructive feedback implementation, the feedback loops are implicit rather than explicit (e.g., 'clarify unclear items, verify, then respond' lacks concrete gates).

The skill is well-organized as an overview with clear sections and well-signaled one-level-deep references to contract.yaml, evals.yaml, task-profile.json, finding.md.tmpl, and routing documents. The 'Read when' annotations at the bottom provide contextual guidance for when to consult references. Route-elsewhere guidance is clear and specific.
