Quality

Content

88%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 a lean, instruction-only fixture with a concrete, executable reference lookup and an explicit safety guard. Its minimalism suits its synthetic verification purpose, with only slight organization gaps.

DimensionReasoningScore

Conciseness

Three short sentences with zero padding or explanation of concepts Claude already knows; every token earns its place, matching the 'lean and efficient; assumes Claude's competence' anchor.

5 / 5

Actionability

It gives a concrete, executable instruction ('Read `references/probe.txt` when validating supporting-resource access') plus an explicit prohibition, but the single example leaves minor gaps in coverage of edge cases.

4 / 5

Workflow Clarity

Per the simple-skill exception, this single-purpose skill has one unambiguous action with a clear trigger condition and no destructive/batch operations requiring validation checkpoints.

5 / 5

Progressive Disclosure

The reference to `references/probe.txt` is real, clearly signaled, and exactly one level deep; it lacks section headers/organization that would push it to a 5, leaving minor organization gaps.

Description

21%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.

This is a synthetic fixture description that names its niche but provides no concrete capabilities, natural trigger terms, or usage conditions. It reads as a labeling label rather than actionable skill guidance.

Suggestions

Add concrete actions the skill performs (e.g., 'Validates supporting-resource access for OpenSquilla skills').

Include a 'Use when...' clause stating the natural trigger condition for invocation.

Surface natural terms a user might say (e.g., 'verify', 'canary check', 'resource access') instead of only technical jargon.

DimensionReasoningScore

Specificity

The phrase 'instruction-only fixture for the OpenSquilla live Skill Hub canary' names a specific domain but describes what the skill IS rather than any concrete action it performs, matching the 'names the domain but actions are minimal or generic' anchor.

2 / 5

Completeness

It offers only a vague 'what' (a fixture) and entirely omits any 'when to use' guidance; per the guideline a missing 'Use when...' clause and vague what cap it at the 'vague what, no when' anchor.

2 / 5

Trigger Term Quality

Terms like 'fixture', 'canary', and 'Skill Hub' are technical jargon with no natural phrases a user would say when needing this skill, matching the 'no natural keywords; only technical jargon' anchor.

1 / 5

Distinctiveness Conflict Risk

The proper-noun niche 'OpenSquilla live Skill Hub canary' is somewhat specific, but as a generic fixture it could still overlap with other verification skills rather than having distinct functional triggers.
