Validation for skill structure
Discovery
89%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 well-crafted description for a narrow, single-purpose skill. It excels at completeness and distinctiveness with explicit trigger terms and clear 'Use when' guidance. The only limitation is the inherently simple nature of the skill, which offers just one action.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names a specific action ('Display colorful ANSI art of the word "ultrathink"') but describes only a single, narrow capability rather than multiple concrete actions. | 2 / 3 |
Completeness | Clearly answers both what ('Display colorful ANSI art of the word "ultrathink"') and when ('Use when the user says "ultrathink" or invokes /ultrathink') with explicit triggers. | 3 / 3 |
Trigger Term Quality | Includes the exact natural keywords users would say: 'ultrathink' and '/ultrathink'. These are precise trigger terms that match user invocation patterns. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with unique trigger terms ('ultrathink', '/ultrathink') that are unlikely to conflict with any other skill. The specific ANSI art output is also unique. | 3 / 3 |
Total | 11 / 12 Passed |
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 exemplary simple skill that does exactly what it needs to do with maximum efficiency. It provides a complete, executable command with clear constraints, respects Claude's intelligence by not explaining basic concepts, and is appropriately scoped for its single-purpose nature.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean - contains only the essential instruction and the executable command. No unnecessary explanation of what ANSI codes are or how bash works. | 3 / 3 |
Actionability | Provides a complete, copy-paste ready bash command that is immediately executable. The instruction is unambiguous: run this command, add no commentary. | 3 / 3 |
Workflow Clarity | This is a simple single-action skill with no multi-step process. The single action (run the bash command) is completely unambiguous, and the constraint (no other output) is explicit. | 3 / 3 |
Progressive Disclosure | For a skill under 50 lines with no need for external references, the content is appropriately self-contained and well-organized with a clear header and instruction. | 3 / 3 |
Total | 12 / 12 Passed |
Validation
81%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
