Quality

Content

80%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.

An efficient, well-structured review-guardrail skill that stays lean and assumes Claude's competence; its main gap is workflow sequencing, which is implicit rather than an explicit validated step list.

Suggestions

Add a short numbered review sequence (e.g., 1. inspect changed fixtures, 2. check normalization sentinels, 3. verify cross-output alignment, 4. report grouped findings) with an explicit validation checkpoint to lift workflow_clarity above 3.

Include one concrete example contrasting an intentional fixture change against an ad hoc patch to make the guardrails immediately actionable.

DimensionReasoningScore

Conciseness

Lean and well-sectioned with no padding or explanation of concepts Claude already knows; the 99999 sentinel note is non-obvious domain knowledge that earns its tokens.

5 / 5

Actionability

Concrete file paths, specific guardrail directives, a named sentinel, and explicit do/don't limits give mostly executable guidance, though a worked example of good vs. bad fixture drift would close the gap to a 5.

4 / 5

Workflow Clarity

The scope->files->guardrails->limits structure implies a review order and includes an embedded verify-before-report checkpoint, but there is no explicit numbered sequence or error-recovery feedback loop, leaving checkpoints implicit.

3 / 5

Progressive Disclosure

Under 50 lines, single-purpose, no bundle files (references/scripts/assets are empty), and organized into clearly labeled sections, satisfying the simple-skill exception for a top score.

Description

82%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 concise, well-targeted description with an explicit trigger clause and very low conflict risk; its only weakness is relying on a single action verb rather than enumerating multiple concrete review actions.

Suggestions

Expand 'reviewing' into 1-2 concrete actions (e.g., 'detect fixture drift across MCP, CLI, and JSON outputs and flag ad hoc normalization') to lift specificity toward a 4-5.

Add a natural synonym or file extension (e.g., '.json', 'snapshot') to broaden trigger-term coverage toward a 5.

DimensionReasoningScore

Specificity

Names the domain ('snapshot fixture changes') and the three contract channels (MCP, CLI, JSON) but uses only one action verb ('reviewing'), matching the anchor for 1-2 concrete actions without comprehensive coverage.

3 / 5

Completeness

Explicitly answers both what (reviewing fixture changes for MCP/CLI/JSON contract integrity) and when ('Use when reviewing XcodeBuildMCP snapshot fixture changes...') with a concrete trigger phrase.

5 / 5

Trigger Term Quality

Strong relevant keywords ('snapshot fixture changes', 'MCP', 'CLI', 'JSON', 'contract integrity') with an explicit 'Use when reviewing...' trigger, though synonyms and file extensions are absent.

4 / 5

Distinctiveness Conflict Risk

Highly specific to a named tool's snapshot fixtures across three output channels, giving it a clear niche with minimal conflict risk against other skills.
