The body is lean and task-focused with executable code and no padding explaining concepts Claude already knows. Not score 2 because it avoids unnecessary explanation; every section earns its place.

Both paths give copy-paste-ready executable code: a concrete web_fetch(url=...) call and a complete requests+BeautifulSoup fallback with a timeout. Not score 2 because the code is real and complete rather than pseudocode.

The prefer-web_fetch-then-fallback-to-Python decision is clearly sequenced, and as a simple skill with no destructive/batch operations no validation checkpoints are required. Not score 2 because the branching is unambiguous.

Under 50 lines with no external bundle files, organized into clearly labeled sections (web_fetch, Python fallback, Guidelines), satisfying the simple-skill allowance for a top score. Not score 2 because the content is appropriately organized rather than a monolithic wall.

"Search the web and fetch web pages" names two concrete actions, matching the anchor that identifies a domain and some actions but falls short of a longer list of granular specific operations. It is not score 1 (vague/abstract) but not a comprehensive multi-action list like the score 3 example.

It states what ("Search the web and fetch web pages") and an explicit when ("Use when the user asks to search for information, look something up, or fetch a URL"), matching the score 3 anchor with an explicit 'Use when...' clause. Not score 2 because the when is explicit, not merely implied.

"search for information, look something up, or fetch a URL" gives good coverage of natural phrases users would actually say. Not score 2 because it includes multiple common variations rather than just one keyword.

"Search the web and fetch web pages" carves a clear niche with distinct triggers unlikely to conflict with other skills. Not score 2 because the triggers (search/look up/fetch URL) are specific enough to avoid overlap.
