Discovery
7%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 description is essentially a template placeholder with no substantive content. It repeats the skill name as its only trigger term, provides no concrete actions or capabilities, and lacks any explicit guidance on when Claude should select this skill. It would be nearly useless for skill selection among a large set of available skills.
Suggestions
Add specific concrete actions the skill performs, e.g., 'Creates ASCII art diagrams including flowcharts, box diagrams, sequence diagrams, and tree structures using plain text characters.'
Add an explicit 'Use when...' clause with natural trigger terms, e.g., 'Use when the user asks for text-based diagrams, ASCII art, plain text flowcharts, terminal-friendly visuals, or box-drawing character layouts.'
Expand trigger terms to include natural variations users would say: 'ASCII diagram', 'text diagram', 'plain text flowchart', 'box drawing', 'terminal diagram', 'monospace art'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description names the domain ('ascii art diagram') but does not describe any concrete actions. There are no specific capabilities listed like 'creates flowcharts', 'converts images to ASCII', or 'generates box diagrams'. It only states the skill name and category. | 1 / 3 |
Completeness | The description fails to answer both 'what does this do' (no concrete actions) and 'when should Claude use it' (no explicit 'Use when...' clause). The 'Triggers on' line is just the skill name repeated, not meaningful trigger guidance. | 1 / 3 |
Trigger Term Quality | The trigger terms are just the skill name repeated twice ('ascii art diagram creator'). It misses natural user phrases like 'draw a diagram', 'text-based diagram', 'ASCII flowchart', 'box drawing', 'terminal art', or 'plain text diagram'. | 1 / 3 |
Distinctiveness Conflict Risk | The term 'ascii art diagram' is somewhat specific and distinguishes it from general diagramming or image creation skills. However, the 'Visual Content' category label is generic and could overlap with other visual skills, and the lack of specific use cases weakens distinctiveness. | 2 / 3 |

Implementation
0%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is an empty template/placeholder with no actual instructional content about creating ASCII art diagrams. It contains only generic boilerplate text that repeats the skill name without providing any actionable guidance, examples, character sets, layout techniques, or concrete instructions. It fails on every dimension of the rubric.
Suggestions
Add concrete ASCII art examples showing common diagram types (flowcharts, sequence diagrams, architecture diagrams) with the actual character patterns used (e.g., +--+, |, ->, arrows, boxes).
Provide executable techniques: specific character sets for lines/corners/arrows, alignment rules, and copy-paste-ready templates for common diagram structures.
Include a clear workflow: 1) Determine diagram type, 2) Sketch layout with box dimensions, 3) Draw using specific characters, 4) Validate alignment by checking column counts.
Remove all boilerplate sections (When to Use, Example Triggers, Capabilities) that describe the skill meta-information rather than teaching how to create ASCII art diagrams.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely filler and boilerplate. It explains nothing Claude doesn't already know, repeats the phrase 'ascii art diagram creator' excessively, and provides zero actual instructional content about creating ASCII art diagrams. | 1 / 3 |
Actionability | There is no concrete guidance whatsoever—no code, no examples of ASCII art, no commands, no techniques, no character sets to use, no formatting rules. The skill describes rather than instructs and provides nothing executable. | 1 / 3 |
Workflow Clarity | There are no steps, no workflow, no sequence of actions. The 'Capabilities' section vaguely claims 'step-by-step guidance' but none is actually provided. | 1 / 3 |
Progressive Disclosure | The content is a monolithic block of generic placeholder text with no meaningful structure, no references to detailed materials, and no useful organization of content. | 1 / 3 |
Total | 4 / 12 Passed |
