The body is concise, fully actionable, and unambiguous for a simple single-purpose demo skill. It provides an exact response and clear invocation guidance with no wasted tokens.

Dimension	Reasoning	Score
Conciseness	The body is short and lean; it does not explain concepts Claude already knows and the brief purpose paragraph earns its place for a demo skill, matching the 'lean and efficient; every token earns its place' anchor.	3 / 3
Actionability	'respond with exactly: "Hello from demo-plugin-one / demo-skill-one (paorikku-castle workspace)."' is a precise, copy-paste-ready instruction, matching the 'fully executable; copy-paste ready' anchor.	3 / 3
Workflow Clarity	This is a simple single-action skill with an unambiguous response; per the simple_skills scoring note, workflow clarity can score 3 when the single action is clear and there are no destructive or batch operations requiring validation.	3 / 3
Progressive Disclosure	The skill is under 50 lines with a single, self-contained task and clear prose; per the simple_skills guideline, progressive disclosure can score 3 with well-organized content even without external file references.	3 / 3
	Total	12 / 12 Passed

Description

35%

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 states a specific purpose but reads as internal testing jargon with no natural user triggers and no explicit 'when to use' guidance. It is distinguishable mainly by its narrow demo scope rather than by strong trigger phrasing.

Suggestions

Add an explicit 'Use when...' clause stating when Claude should invoke this skill.

Replace jargon ('verify global vs project install behavior across agents') with natural trigger terms a user would actually say.

Broaden the action list beyond a single 'verify' verb to make capabilities more concrete.

Dimension	Reasoning	Score
Specificity	Names a concrete domain ('global vs project install behavior across agents') and the action 'verify', but does not enumerate multiple distinct actions, matching the 'names domain and some actions, but not comprehensive' anchor.	2 / 3
Completeness	It states what the skill does but provides no 'Use when...' trigger guidance, so the 'when' is missing and completeness is capped at 2 per the judging guideline.	2 / 3
Trigger Term Quality	The phrasing 'verify global vs project install behavior across agents' is technical jargon rather than terms a user would naturally say; it lacks common natural keyword variations, fitting the 'technical jargon or overly generic' anchor.	1 / 3
Distinctiveness Conflict Risk	The narrow demo/test purpose is fairly distinct, but the weak, jargon-like triggers mean it could still overlap conceptually with other install/tooling skills, matching the 'somewhat specific but could still overlap' anchor rather than the clearly niche level above.	2 / 3
