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 clearly states what the skill does (extract clean markdown, remove clutter), when to use it (URLs, documentation, articles), and explicitly differentiates itself from a similar skill (WebFetch). The description uses third person voice correctly and includes natural trigger terms users would actually say.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists specific concrete actions: 'Extract clean markdown content from web pages', 'removing clutter and navigation', 'save tokens'. Names the specific tool (Defuddle CLI) and describes what it produces. | 3 / 3 |
Completeness | Clearly answers both what ('Extract clean markdown content from web pages using Defuddle CLI, removing clutter') AND when ('Use instead of WebFetch when the user provides a URL to read or analyze, for online documentation, articles, blog posts'). | 3 / 3 |
Trigger Term Quality | Includes natural terms users would say: 'URL', 'read', 'analyze', 'documentation', 'articles', 'blog posts', 'web page'. Also differentiates from WebFetch which helps with skill selection. | 3 / 3 |
Distinctiveness Conflict Risk | Explicitly distinguishes itself from WebFetch ('Use instead of WebFetch'), specifies its niche (clean markdown extraction vs general web fetching), and lists specific use cases that create a clear boundary. | 3 / 3 |
Total | 12 / 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 skill file that demonstrates excellent token efficiency while remaining fully actionable. It provides everything Claude needs to use Defuddle CLI without any unnecessary explanation of concepts Claude already understands. The structure is clean and the commands are immediately executable.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what web scraping is or why clean content matters. Every line provides actionable information Claude needs. | 3 / 3 |
Actionability | Provides complete, copy-paste ready commands with clear flags. Installation command, basic usage, file output, and metadata extraction are all executable as written. | 3 / 3 |
Workflow Clarity | This is a simple single-task skill (extract content from URL). The workflow is unambiguous: install if needed, run command with --md flag. No multi-step validation needed for a read-only operation. | 3 / 3 |
Progressive Disclosure | For a skill under 50 lines with no need for external references, this is well-organized with clear sections (Usage, Output formats). The table format for flags aids quick reference. | 3 / 3 |
Total | 12 / 12 Passed |
