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.

'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.

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.

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.

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.

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.

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.

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.
