Quality

Content

11%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 placeholder with no actionable guidance, no workflow, and no meaningful structure; it is lean but content-free, so it scores near the bottom across all dimensions.

Suggestions

Replace the placeholder sentence with concrete, executable instructions (commands or code) for the skill's actual task.

Add a clear workflow with sequenced steps and a validation checkpoint if the task is destructive or batch-oriented.

Organize content under purposeful section headers so the SKILL.md serves as an overview pointing to any needed detail files.

DimensionReasoningScore

Conciseness

The body is short and unpadded, but 'This skill has non-standard frontmatter fields.' conveys no task-relevant information, so the tokens do not earn their place; it falls between verbose (not applicable) and efficient.

2 / 5

Actionability

There is no concrete code, command, or executable guidance — only a single descriptive sentence, matching the 'Entirely vague or abstract; no concrete code or commands' anchor.

1 / 5

Workflow Clarity

No steps or sequence exist; the body is a single declarative statement with no workflow to follow, so it cannot benefit from the simple-skill exception (there is no defined task).

1 / 5

Progressive Disclosure

Structure is minimal — one heading and one sentence with no references or organization; while not a wall of text, it lacks the well-organized sections needed for a higher score.

Description

0%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 description is a placeholder describing the skill's own frontmatter rather than any capability, so it fails on every dimension: no actions, no triggers, no what/when, and no distinctiveness.

Suggestions

Rewrite the description to state a concrete capability, e.g. 'Validates SKILL.md frontmatter fields against the known schema.'

Add an explicit 'Use when...' clause naming natural trigger phrases a user would say.

Drop the meta commentary ('A skill with...') in favor of third-person action verbs describing what the skill does.

DimensionReasoningScore

Specificity

The description 'A skill with an unknown frontmatter field.' names no concrete action and uses only abstract meta-language about the skill itself, matching the 'Entirely vague; no concrete actions' anchor.

1 / 5

Completeness

It states neither a real 'what' (no capability described) nor any 'when' trigger guidance, and a missing 'Use when...' clause caps completeness at 3 at most; here both are absent so it sits at the bottom.

1 / 5

Trigger Term Quality

No natural keywords a user would say; 'unknown frontmatter field' is technical jargon with none of the natural phrases users actually utter, matching the lowest anchor.

1 / 5

Distinctiveness Conflict Risk

The description is entirely generic meta-text unrelated to any niche, offering nothing to distinguish it from other skills, matching the 'Entirely generic' anchor.
