Quality

Content

92%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 appropriately concise and clearly structured for a trivial single-purpose skill; it would benefit only from a concrete example greeting to make the action fully copy-paste ready.

Dimension	Reasoning	Score
Conciseness	The body is lean (under 15 lines) with no padding or explanations of concepts Claude already knows; every line earns its place.	5 / 5
Actionability	It gives a concrete instruction ("respond with a friendly greeting and confirm that the extension system is working") and an invocation path, but lacks a copy-paste-ready example greeting, leaving a minor gap.	4 / 5
Workflow Clarity	This is a simple single-action skill with an unambiguous instruction; per the simple-skill exception the single action is fully clear with no validation needed.	5 / 5
Progressive Disclosure	The content is well-organized with a clear overview and a Usage section, and being under 50 lines with no need for external references it satisfies the simple-skill exception.	5 / 5

Description

28%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 concise and accurate but functions as an internal demo label rather than a user-facing trigger; it lacks concrete actions and any explicit "when to use" guidance.

Suggestions

Add a concrete "Use when..." clause describing when this skill should be invoked (e.g., testing that the extension system is working).

Replace the internal phrase "extension-provided skills" with natural user-facing trigger terms.

State the concrete action the skill performs ("Responds with a friendly greeting") instead of the abstract "Demonstrates".

Dimension	Reasoning	Score
Specificity	The description names the domain ("hello world skill", "extension-provided skills") but the only action stated is "Demonstrates", which is minimal and generic rather than a concrete capability.	2 / 5
Completeness	It states a vague "what" (demonstrates extension-provided skills) but provides no "Use when..." clause or any trigger guidance, and the what is itself weak, so it falls at the low end between anchors 1 and 3.	2 / 5
Trigger Term Quality	Phrases like "aif-ext-hello extension" and "extension-provided skills" are technical/internal labels; a user would not naturally say these when needing this skill, and natural trigger phrases are absent.	2 / 5
Distinctiveness Conflict Risk	The hello-world/demo niche is somewhat specific, but the generic phrasing ("Demonstrates extension-provided skills") could overlap with other extension test skills, so it sits at the midpoint anchor.	3 / 5
