Quality

Content

86%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A tight, well-structured review skill that assumes Claude's competence and provides concrete inspection targets, guardrail checks, and validation commands; the only gap is the lack of violation examples and an explicit error-recovery loop.

Suggestions

Add a brief example or two of what a guardrail violation looks like (e.g., a silent fallback pattern or a parallel invocation path) to make the review checks more concrete.

Add an explicit feedback step after validation, e.g. 'If validation fails, report the failing guardrail and the offending path before proceeding.'

DimensionReasoningScore

Conciseness

The body is lean and directive throughout — file paths, guardrail bullets, and validation commands with no padding and no explanation of concepts Claude already knows; every token earns its place.

5 / 5

Actionability

Concrete, mostly executable guidance is present (specific files to inspect, rule-based guardrails with conditions like 'only when routing.stateful requires it', and copy-paste validation commands), but no examples of what a guardrail violation looks like to look for.

4 / 5

Workflow Clarity

Sections are clearly sequenced (scope, files, guardrails, validation) with an explicit Validation section; the skill is review-only so the destructive-cap does not apply, but there is no explicit validate-then-fix feedback loop.

4 / 5

Progressive Disclosure

The skill is under 50 lines, needs no external skill references, and is organized into clear well-signaled sections (Review scope, Files to inspect, Guardrails, Validation), satisfying the simple-skill exception for progressive disclosure.

Description

73%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A specific, well-triggered description that clearly distinguishes its niche; its main weakness is that the 'when' clause echoes the 'what' rather than offering multiple concrete trigger phrasings.

Suggestions

Add distinct user-facing trigger conditions to the 'when' clause (e.g., 'Use when the user asks to verify routing changes, refactors shared handlers, or touches daemon/CLI invocation paths') rather than restating the review scope.

Consider adding 1-2 more concrete action verbs (e.g., 'verify', 'audit', 'check') so specificity reflects multiple actions rather than a single 'reviewing'.

DimensionReasoningScore

Specificity

The description names the domain (XcodeBuildMCP runtime boundary changes) and applies one concrete action ('reviewing') across four specific boundary paths (MCP, CLI, daemon, IDE bridge), but lists only a single action verb rather than multiple distinct actions.

3 / 5

Completeness

An explicit 'Use when...' clause is present (so the 3-cap does not apply) and both what and when are answered, but the 'when' largely restates the 'what' rather than enumerating distinct user-expressed trigger conditions.

4 / 5

Trigger Term Quality

Natural terms a developer would say are present ('reviewing', 'runtime boundary', 'MCP', 'CLI invocation', 'daemon', 'Xcode IDE bridge'), but there are no synonyms or file-extension variants to reach comprehensive coverage.

4 / 5

Distinctiveness Conflict Risk

The description targets a clear, narrow niche (runtime boundary routing in a specific codebase) with distinct triggers and minimal realistic overlap with other skills.
