Quality

Content

67%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 well-structured router body with concrete commands, a clear decision tree, and clean progressive disclosure. It loses points mainly on repeated CLI tool listings and time-sensitive version detail that should sit in a deprecated section, plus unverifiable sub-skill references.

Suggestions

Consolidate the devicectl/simctl/Axiom CLI tool list so it appears once; reference it from the other locations instead of repeating it three times.

Move version-specific statements (Xcode 26.3, Xcode 27) into a clearly labeled version/deprecated section so time-sensitive detail does not clutter the main guidance.

Verify the referenced skills/xcode-mcp-setup.md, xcode-mcp-tools.md, xcode-mcp-ref.md, and axe-ref.md files exist in the bundle, or note that they are sibling-suite skills rather than local bundle files.

Dimension	Reasoning	Score
Conciseness	The body is information-dense and avoids explaining basics, but it repeats the devicectl/simctl/Axiom CLI tool list three times and carries time-sensitive version statements (Xcode 26.3, Xcode 27) outside any deprecated/old-patterns section, which could be tightened.	3 / 5
Actionability	Provides concrete executable commands (sudo xcrun mcp-server enable, xcrun mcpbridge run-agent, xcrun agent skills export) and clear Read-routing directives, with only minor gaps since detailed tool usage is delegated to sub-skills.	4 / 5
Workflow Clarity	A clear routing workflow is laid out via When-to-Use, Routing Logic, and a graphviz decision tree, but there are no error-recovery feedback loops, which keeps it just short of the top anchor.	4 / 5
Progressive Disclosure	Structure is good: an overview with well-signaled, one-level-deep Read references to sub-skills, but the referenced skills/*.md paths are not present in the bundle, leaving a minor organization gap.	4 / 5
	Total	15 / 20 Passed

Description

92%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 tightly written router description that names concrete tools and an explicit use-when trigger, with a clear niche and low conflict risk. Only slight weakness is trigger-term breadth (missing synonyms and extensions).

Dimension	Reasoning	Score
Specificity	Names the Xcode MCP domain plus multiple concrete tools (XcodeRead, BuildProject, RunSomeTests, RenderPreview) and operation categories (setup, tool reference, workflows, troubleshooting), giving comprehensive coverage rather than a single action.	5 / 5
Completeness	Explicitly states what the skill covers and opens with a concrete 'Use when connecting... or working with ANY Xcode MCP tool' trigger clause answering both what and when.	5 / 5
Trigger Term Quality	Strong natural keywords users would say (xcrun mcpbridge, BuildProject, RenderPreview, setup, troubleshooting), but missing common synonyms and file extensions, so not fully comprehensive.	4 / 5
Distinctiveness Conflict Risk	The Xcode MCP niche is narrow and the triggers (mcpbridge, mcp-server, specific MCP tool names) are distinct, giving minimal overlap risk with other skills.	5 / 5
	Total	19 / 20 Passed
