Quality

Content

93%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.

The body is a tight, actionable review checklist with concrete file targets, guardrails, and executable validation commands, well-structured for a simple instruction-only skill. The only gap is the absence of an explicit fix-and-retry feedback loop in the validation section.

Suggestions

Add a short feedback loop under Validation (e.g. 'If a check fails: read the failure, fix the test or guardrail violation, and re-run the failing command before proceeding') to raise workflow clarity.

Consider noting the expected pass condition for each validation step so it is unambiguous when a checkpoint is satisfied.

DimensionReasoningScore

Conciseness

Lean ~35-line body with no padding or explanation of concepts Claude already knows; every line (file globs, guardrails, validation commands) earns its place.

5 / 5

Actionability

Provides concrete file globs to inspect, prescriptive guardrail directives, and copy-paste-ready validation commands covering the common touched-test scenarios.

5 / 5

Workflow Clarity

Clear sequence (Review scope → Files → Guardrails → Validation) with explicit conditional validation checkpoints, but no error-recovery feedback loop describing what to do when a check fails.

4 / 5

Progressive Disclosure

Under 50 lines with no need for external bundle references (none exist), organized into clearly labeled sections that make navigation trivial.

Description

87%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.

The description is specific, well-triggered, and clearly distinct, explicitly pairing a concrete 'Use when' clause with the review action and five named boundary types. Its only weakness is a single action verb that keeps specificity just short of fully comprehensive.

DimensionReasoningScore

Specificity

Names the domain (XcodeBuildMCP tests) and enumerates five concrete boundary types (unit, snapshot, schema, smoke, external process), but the action is a single verb ('reviewing'), leaving minor coverage gaps versus a fully comprehensive action list.

4 / 5

Completeness

Explicitly answers both 'what' (reviewing tests for boundary correctness) and 'when' via a concrete 'Use when reviewing...' trigger phrase enumerating the relevant boundary categories.

5 / 5

Trigger Term Quality

Includes natural developer phrasing ('reviewing XcodeBuildMCP tests', 'unit', 'snapshot', 'schema', 'smoke') with good coverage; a few common synonyms (e.g. 'integration tests', 'e2e') are missing.

4 / 5

Distinctiveness Conflict Risk

Targets a named project (XcodeBuildMCP) with a narrow test-boundary niche, yielding distinct triggers and minimal overlap risk with other skills.
