Conciseness

The body is lean and well-sectioned with no padding or explanations of concepts Claude already knows — e.g., "Build a conversion URL as `https://markdown.new/<target-url>`" states only what is needed; matches the 'lean and efficient, every token earns its place' anchor and is not a 4 since there are no over-explanation instances to trim.

Actionability

Provides concrete, executable guidance including the exact conversion URL pattern, parameter values (`method=auto|ai|browser`, `retain_images=true|false`), and a copy-paste example URL `https://markdown.new/https://example.com?method=browser&retain_images=true`; not a 5 because the actual fetch relies on the abstract "built-in fetch tool" rather than a fully specified invocation, and not a 3 because the steps and parameters are specific and usable.

Workflow Clarity

The four-step workflow has explicit validation checkpoints (malformed/missing URL, query parameters, tool unavailability) and feedback loops (retry with `method=browser` on empty results, `retain_images=true` for image-rich pages), plus a Failure Policy section; matches the anchor requiring explicit validation and error-recovery loops, and the simple-skill exception supports a 5.

Progressive Disclosure

Content is self-contained with no need for external references and is organized into clear, well-signaled sections (Use This Skill When, Do Not Use, Workflow, Optional Parameters, Examples, Failure Policy); per the simple-skills note, a self-contained skill with well-organized sections scores 5, and there is no nested or buried reference structure to penalize it.

Specificity

Names the domain and one concrete action — "Retrieve the Markdown version of a public web page from a URL ... using ... markdown.new" — but lists only a single conversion action rather than several, matching the '1-2 concrete actions, not comprehensive' anchor; not a 2 because the action is concrete rather than generic, and not a 4 because no breadth of actions is enumerated.

Completeness

Explicitly answers both what ("Retrieve the Markdown version of a public web page from a URL using ... markdown.new") and when ("Use when a user asks for page content in Markdown ... or URL-to-Markdown conversion") with concrete trigger phrases, matching the top anchor; a 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

Includes natural user phrases like "page content in Markdown", "cleaner extracted page content for LLM use", and "URL-to-Markdown conversion", giving good keyword coverage with synonyms; not a 5 because coverage stops short of exhaustive synonyms/extensions, and not a 3 because multiple natural terms are present rather than just one generic keyword.

Distinctiveness Conflict Risk

The markdown.new niche is distinct with specific triggers, but the phrase "cleaner extracted page content for LLM use" overlaps with general web-fetch/browse skills, matching 'mostly distinct; minor overlap risk'; not a 5 because of that overlap, and not a 3 because the markdown.new mechanism is clearly specific.
