Discovery

85%

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 strong skill description that clearly defines its scope around draw.io diagrams with specific capabilities and explicit usage triggers. The main weakness is the trigger term coverage, which focuses on technical terms but may miss users who ask about 'flowcharts', 'diagrams', or 'architecture diagrams' without mentioning draw.io specifically.

Suggestions

Add common user-facing terms like 'flowchart', 'architecture diagram', 'visual diagram', or 'diagramming' to improve trigger term coverage for users who may not know the tool name.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'diagram creation, editing, and review', '.drawio XML editing, PNG conversion, layout adjustment, and AWS icon usage' - these are clear, actionable capabilities.

3 / 3

Completeness

Clearly answers both what ('diagram creation, editing, and review') and when ('Use for .drawio XML editing, PNG conversion, layout adjustment, and AWS icon usage') with explicit trigger guidance.

3 / 3

Trigger Term Quality

Includes good technical terms like 'draw.io', '.drawio', 'XML', 'PNG', 'AWS icon', but misses common user variations like 'flowchart', 'diagram', 'architecture diagram', or 'visual diagram'.

2 / 3

Distinctiveness Conflict Risk

Very specific niche with distinct triggers - 'draw.io', '.drawio XML', and 'AWS icon usage' are highly specific and unlikely to conflict with other diagramming or document skills.

Implementation

100%

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

This is an excellent skill document that demonstrates strong technical writing. It efficiently covers draw.io diagram creation with concrete XML examples, clear workflows, and comprehensive best practices. The checklist provides effective validation, and the progressive disclosure through external references keeps the main document focused.

DimensionReasoningScore

Conciseness

The content is lean and efficient, presenting information in tables, code blocks, and bullet points without explaining concepts Claude already knows. Every section provides specific, actionable information without padding.

3 / 3

Actionability

Provides fully executable commands, complete XML examples, and specific coordinate calculations. Code snippets are copy-paste ready with clear option explanations in tables.

3 / 3

Workflow Clarity

Section 4.1 provides clear sequential steps for coordinate adjustment with explicit verification step. The checklist in Section 8 serves as a comprehensive validation checkpoint, and multiple sections emphasize 'verify in PNG' as feedback loops.

3 / 3

Progressive Disclosure

Well-organized with clear section hierarchy. References to external files (layout guidelines, AWS icons, scripts) are one level deep and clearly signaled in Section 7. Content is appropriately split between overview and detailed references.
