excalidraw-diagram
Generate Excalidraw diagrams from text content. Supports three output modes - Obsidian (.md), Standard (.excalidraw), and Animated (.excalidraw with animation order). Triggers on "Excalidraw", "画图", "流程图", "思维导图", "可视化", "diagram", "标准Excalidraw", "standard excalidraw", "Excalidraw动画", "动画图", "animate".

Discovery
100%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 excels across all dimensions. It provides specific capabilities with three distinct output modes, comprehensive trigger terms in multiple languages, explicit trigger guidance, and a clear niche that distinguishes it from other diagramming tools.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists specific concrete actions: 'Generate Excalidraw diagrams from text content' and details three distinct output modes (Obsidian .md, Standard .excalidraw, Animated .excalidraw with animation order). | 3 / 3 |
Completeness | Clearly answers both what (generate Excalidraw diagrams with three output modes) and when (explicit 'Triggers on' clause with comprehensive list of trigger terms). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms including English ('Excalidraw', 'diagram', 'animate') and Chinese equivalents ('画图', '流程图', '思维导图', '可视化'), plus specific variations like 'standard excalidraw' and 'Excalidraw动画'. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear niche around Excalidraw specifically, file format details (.md, .excalidraw), and unique trigger terms that wouldn't overlap with generic diagramming or visualization skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a comprehensive and highly actionable skill with excellent concrete guidance including executable JSON templates, specific color values, and clear formulas. However, it suffers from verbosity with duplicated content (Element Template appears twice, JSON structures repeated) and could benefit from better progressive disclosure by moving detailed reference tables to separate files.
Suggestions
Remove duplicate Element Template section and consolidate JSON structure examples that appear multiple times
Move detailed color palette tables and element type specifications to the referenced excalidraw-schema.md file to reduce main document length
Consolidate the 'Required Fields for All Elements' section with the earlier 'Element Template' section as they contain nearly identical information
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill contains useful information but is verbose with significant repetition. The Element Template section appears twice with nearly identical content, and the JSON structure examples are duplicated. Some explanations could be tightened. | 2 / 3 |
Actionability | Provides fully executable JSON templates, specific color palettes with hex values, concrete formulas for text centering, and copy-paste ready code blocks. The output format examples are complete and specific. | 3 / 3 |
Workflow Clarity | Clear 7-step workflow with explicit mode detection, numbered implementation steps, and specific validation requirements. The 'Common Mistakes to Avoid' section serves as a validation checklist for error prevention. | 3 / 3 |
Progressive Disclosure | References external file (references/excalidraw-schema.md) appropriately, but the main document is quite long with content that could be split. The detailed color palettes and element templates could be in separate reference files. | 2 / 3 |
Total | 10 / 12 Passed |
