Quality

Content

78%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 content is compact, well-structured, and actionable via a concrete tool-routing table and sequenced workflow with validation, with only minor gaps (a duplicated purpose line, no usage examples, and no explicit error-recovery feedback loop).

Suggestions

Add an explicit feedback loop after the validate step (e.g., "If validation fails, fix the reported issues and re-run design_validate before proceeding") to push workflow_clarity toward 5.

Remove the redundant "## Purpose" line (it repeats the frontmatter description) or replace it with unique framing to improve conciseness.

Include one or two short worked examples of calling a tool (e.g., design_create_screen for a frame, design_update_shapes for a shape) to move actionability from 4 to 5.

DimensionReasoningScore

Conciseness

The body is lean with no concept over-explanation and a dense tool-routing table; not a 5 because the "## Purpose" line duplicates the frontmatter description verbatim and could be trimmed.

4 / 5

Actionability

The tool-routing table lists concrete executable tool names (design_create_screen, design_update_shapes, etc.) mapped to uses; not a 5 because no worked usage examples are shown for the common cases.

4 / 5

Workflow Clarity

A clear 5-step sequence with an explicit "Validate the resulting design" checkpoint plus a Completion-gates checklist; not a 5 because no validate→fix→retry feedback loop is described for error recovery.

4 / 5

Progressive Disclosure

At ~35 lines the self-contained body is organized into well-signaled sections (Purpose, Tool routing, Workflow, Completion gates, Boundaries, Delivery) with no nested references, meeting the simple-skill exception for a 5.

Description

66%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 specific and names a clear niche with concrete object types, but it omits any explicit "Use when" trigger guidance, which caps completeness and slightly raises conflict risk.

Suggestions

Append a "Use when..." clause naming concrete trigger phrases (e.g., "Use when creating or editing Kun Design screens, shapes, diagrams, or design systems") to lift completeness above 3.

Add natural synonyms or file extensions users might say (e.g., "frames", ".design files") to broaden trigger-term coverage toward 5.

Introduce one or two additional distinct action verbs (arrange, animate, validate) in the description to move specificity from 4 to 5.

DimensionReasoningScore

Specificity

Quotes "Create and edit" applied to six concrete object types ("screens, editable shapes, diagrams, design systems, layouts, and motion") match the anchor listing several specific actions; not a 5 because distinct action verbs are limited to create/edit with no delete/arrange/animate coverage.

4 / 5

Completeness

The description gives a clear "what" ("Create and edit Kun Design screens...") but no "when"/"Use when" clause, which per the judging guidelines caps completeness at 3.

3 / 5

Trigger Term Quality

Natural domain terms ("screens", "editable shapes", "diagrams", "design systems", "layouts", "motion") give good keyword coverage; not a 5 because synonyms, file extensions, and a "Use when" trigger phrase are absent.

4 / 5

Distinctiveness Conflict Risk

The "Kun Design" niche is mostly distinct with limited overlap; not a 5 because without an explicit trigger clause it could still overlap with adjacent canvas/design skills.
