Quality

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is lean, dense, and highly actionable, with concrete function contracts and formulas organized into clear sections ending in a validation checklist. No bundle files exist, and the shallow cross-references are appropriately signaled.

DimensionReasoningScore

Conciseness

The body is information-dense and assumes Claude's competence — no boilerplate explaining boards or opacity — with every line carrying implementation detail (function names, opacity values, scale formulas); only a few brief clarifying phrases appear.

3 / 3

Actionability

Gives highly concrete, actionable guidance: exact function contracts, return values, formulas ('scale follows 0.6 + 0.4 * currentOpacity', 'rate dt * 20'), and file references — actionable for an instruction-only skill, which the rubric does not penalize for lacking code blocks.

3 / 3

Workflow Clarity

Organized into clear sections (Mental model, Reveal rules, Interaction rules, Validation) with an explicit validation checklist of expected behaviors; no destructive/batch loop is required, and the checklist serves as the verification checkpoint.

3 / 3

Progressive Disclosure

A single, well-organized SKILL.md with no bundle files present; inline cross-references ('buildHomeBorder() in the home board border section', source files) are one level deep and clearly signaled, satisfying the well-organized-sections bar for a no-external-reference skill.

Description

72%

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 has strong trigger terms and is clearly distinctive, but it front-loads the 'when' and leaves the 'what' implicit, capping completeness and specificity below their maximum.

Suggestions

Lead with an explicit capability verb before the trigger clause, e.g. 'Adjusts visibility and reveal behavior for the active Tiny World board. Use when...' so the 'what' is stated, not implied.

Replace the soft catch-all 'or any visibility behavior' with one or two more concrete actions to lift specificity toward fully distinct verbs.

DimensionReasoningScore

Specificity

Names the domain and several concrete actions (ghost boards, panning, jigsaw reveal, visibility behavior), but the actions are largely enumerated nouns under a single gerund 'changing' with a soft catch-all 'any visibility behavior', so they are not fully comprehensive distinct verbs.

2 / 3

Completeness

The 'when' is explicit ('Use when changing...'), but the 'what does this skill do' is only implied from the trigger list rather than stated as a concrete capability, so it does not clearly answer both what and when.

2 / 3

Trigger Term Quality

Covers natural domain terms a user would actually say — 'panning', 'ghost boards', 'multiplayer preview boards', 'jigsaw reveal', 'Tiny World board' — with good coverage and no significant missing variations.

3 / 3

Distinctiveness Conflict Risk

Tightly scoped to 'Tiny World board' visibility with distinctive triggers (jigsaw reveal, ghost boards, multiplayer preview boards), making it unlikely to fire for the wrong skill.
