77%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A lean, well-structured instruction-only skill: exact tool names, an unambiguous format-selection decision guide, and a clear WebFetch-fallback path. The main weakness is redundancy — three sections repeat the same content-type-to-tool mapping and 'How to Use' is filler — alongside the absence of example invocations or edge-case handling such as truncated responses.
Suggestions
Consolidate the three redundant content-type-to-tool mappings ('When to Use' bullets, the 'Available Tools' Best For column, and the 'Format Selection Guide') into a single table, keeping only the WebFetch-failure bullet as a distinct trigger.
Cut the filler 'How to Use' section — 'Call the appropriate tool with the target URL' and 'Process the returned content as needed' add no information beyond the tool table and selection guide.
Add one concrete example invocation for a common case (e.g., calling fetch_json on an API endpoint) and brief guidance for edge cases like truncated output to close the actionability gap.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean overall, but the same content-type-to-tool mapping appears three times ('When to Use' bullets, the 'Available Tools' Best For column, and the 'Format Selection Guide'), and 'How to Use' steps like 'Process the returned content as needed' are filler — mostly efficient but could be tightened (anchor 3). Not 4 because a fully duplicated section is more than minor trimming; not 2 because there is no over-explanation of concepts Claude already knows. | 3 / 5 |
Actionability | Gives exact tool names ('mcp__fetch__fetch_markdown', 'mcp__fetch__fetch_json', etc.) mapped to concrete use cases, plus an explicit default ('Prefer fetch_markdown as the general-purpose fallback for most URLs') — mostly executable guidance with minor gaps (anchor 4). Not 5 because no example invocations or parameter/edge-case guidance (e.g., handling truncated responses) is provided; not 3 because the guidance is concrete and specific rather than pseudocode-level. | 4 / 5 |
Workflow Clarity | A simple, single-purpose skill where the action — pick the format-appropriate tool and call it with the target URL — is unambiguous thanks to the selection guide and stated default preference, with the WebFetch-failure retry path explicitly described. Fetches are read-only so no validation checkpoints are required; the simple-skill exception applies (anchor 5). Not 4 because no checkpoint is actually missing for this non-destructive, non-batch operation. | 5 / 5 |
Progressive Disclosure | At ~42 body lines with no bundle files (references/, scripts/, assets/ do not exist) and well-organized sections (When to Use, Available Tools, How to Use, Format Selection Guide, Fallback), it fits the under-50-lines rule for scoring 5. Not 4 because there are no organization gaps, buried references, or inlined content that belongs in separate files. | 5 / 5 |
