The content is concise, highly actionable, and clear for its single purpose, scoring at the top of conciseness, actionability, and workflow clarity. The only gap is progressive disclosure: a provided reference file is not signaled from the body.

Suggestions

Add a single signaled pointer to the existing reference, e.g. 'For background on why this skill exists, see [background.md](references/background.md).', so the bundled file is discoverable from the body.

Optionally label the purpose paragraph as a short section (e.g. '## Purpose') to make the overview-to-detail split explicit, though the current brevity already reads cleanly.

Dimension	Reasoning	Score
Conciseness	The body is lean: a precise trigger, the exact verbatim response string, and two short purpose sentences, with no padding or explanation of concepts Claude already knows.	3 / 3
Actionability	'respond with exactly:' followed by the copy-paste-ready verbatim string is concrete and unambiguous; for an instruction-only skill this fully meets the top anchor.	3 / 3
Workflow Clarity	This is a simple single-action skill whose single step (reply with the fixed greeting) is stated unambiguously, so per the simple-skills note it earns the top anchor with no validation gaps.	3 / 3
Progressive Disclosure	The body is well-organized into trigger, action, and purpose, but a bundled reference file (references/background.md) exists yet is never signaled or linked from the body, leaving navigation incomplete.	2 / 3

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 clear purpose but reads as internal/technical documentation rather than a user-facing trigger. It lacks natural trigger terms and an explicit 'Use when...' clause, capping completeness and trigger quality.

Suggestions

Add an explicit 'Use when...' clause naming the natural situations that should trigger this skill (e.g., 'Use when testing which demo plugin/skill is active or installed').

Replace the internal jargon ('verify global vs project install behavior across agents') with terms a user would actually say, such as 'say hello', 'which skill is active', or 'test plugin install scope'.

List a couple more concrete actions (e.g., 'respond with a fixed greeting' and 'report which plugin/skill is active') to lift specificity toward the top anchor.

Dimension	Reasoning	Score
Specificity	Names the domain ('global vs project install behavior') and a concrete action ('verify'), but does not list multiple specific concrete actions, so it falls short of the top anchor.	2 / 3
Completeness	It states what the skill does (verify install behavior) but has no 'Use when...' trigger guidance, so the 'when' is missing and completeness is capped at 2.	2 / 3
Trigger Term Quality	It contains only internal/technical phrasing ('verify global vs project install behavior across agents') with no natural keywords a user would actually say when needing this skill.	1 / 3
Distinctiveness Conflict Risk	It occupies a distinct niche (install-scope verification) but lacks clear user-facing triggers, so it could still overlap with similar demo or install-related skills.	2 / 3
