Quality

Content

32%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 an auto-generated documentation summary: it is padded with filler (a truncated 60-line dummy code block and duplicated statistics) and offers no actionable test workflow, though it does organize reference files well with clear one-level-deep navigation. It works as a lookup index but not as operative guidance.

Suggestions

Remove the dummy `long_example` code block and the duplicated Documentation Statistics/Table Summary sections, or move any genuinely useful extracted examples into references/handbook.md.

Add a concrete testing workflow with sequenced steps and a validation checkpoint (e.g., run the build, diff against the golden EPUB, report mismatches, fail on difference) so the skill is actionable for its stated purpose.

Tighten the 'When to Use This Skill' bullets into specific, executable guidance instead of generic verbs like 'Review tutorials' and 'Explore the complete documentation structure'.

DimensionReasoningScore

Conciseness

The body is noticeably padded: a 60-line meaningless `long_example` (x0=0 ... x37=37, truncated mid-line), a Documentation Statistics section that duplicates the Section Overview, and a Table Summary restating inlined content — several unnecessary padded sections rather than the severe concept-explaining verbosity of score 1.

2 / 5

Actionability

Guidance is minimal: the 'When to Use This Skill' bullets are high-level hints ('Look up API references', 'Review tutorials') and the code blocks are decorative extracted samples (`pip install thing`, `print('hello')`) rather than steps Claude should execute, so the specific steps to act are missing.

2 / 5

Workflow Clarity

Despite the skill purporting to support 'testing the epub golden build', no test procedure or sequenced steps appear — only a rough navigational structure (overview → reference files) with no validation checkpoints, fitting the 'rough structure present but steps poorly defined' anchor rather than the steps-missing anchor below only because a Navigation path exists.

2 / 5

Progressive Disclosure

References are real and one-level-deep (references/handbook.md and references/index.md, both present and clearly signaled in a Navigation section; index.md links only to handbook.md), and the bulk detail lives in handbook.md — good structure with minor gaps from inlined filler (long code example, stats) that duplicates the reference file, keeping it below the clean split of score 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 a bare trigger clause tied to internal jargon: it states when to invoke the skill but not concretely what it does. It is distinguishable only by the niche "golden build" term while remaining thin on natural keywords and capability detail.

Suggestions

Add a concrete 'what' clause listing the specific actions the skill performs (e.g., 'Validates an EPUB against the golden build, diffs outputs, and reports mismatches') before the 'Use when' trigger.

Replace or gloss the internal term "golden build" with natural user-facing language (e.g., 'reference EPUB build', 'expected EPUB output') so users would actually say it.

Include common synonyms/extensions (e.g., '.epub', 'EPUB validation', 'golden master') to broaden natural trigger coverage.

DimensionReasoningScore

Specificity

The description names the domain ("epub golden build") but offers only the generic verb "testing" with no concrete actions, matching the 'names the domain but actions are minimal or generic' anchor rather than the entirely-vague anchor below or the 1-2-concrete-actions anchor above.

2 / 5

Completeness

It has an explicit "Use when" trigger ("Use when testing the epub golden build") but no distinct, concrete "what" — the capability collapses into the vague verb "testing", matching the 'only when is present without a real what' anchor.

2 / 5

Trigger Term Quality

"epub" is a natural keyword, but "golden build" is internal jargon a user would not naturally say and "testing" is generic, leaving only one or two generic keywords and missing common natural phrases.

2 / 5

Distinctiveness Conflict Risk

"epub golden build" carves out a fairly specific niche, but the broad "testing epub" framing could still overlap with other epub- or testing-related skills, so it sits at 'somewhat specific but could still overlap' rather than the mostly-distinct anchor above.
