61%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.
The body is well-structured and domain-dense with mostly executable examples and genuine progressive disclosure to three real reference files. Its weaknesses are redundancy across sections (rate limits, expiry limits, reference pointers each repeated), the absence of validation/feedback checkpoints in the batch API workflow, and inlining of web-UI material that belongs in a reference file.
Suggestions
State rate limits, history/clipboard expiry, and reference-file consult cues once each, and cut the duplicated 'Working with Reference Files' summary to a short pointer list — this would tighten conciseness toward anchor 4.
Add explicit validation to Workflow 3 (e.g., check the esearchresult error field, handle empty idlist, back off on HTTP 429) so the batch workflow has real checkpoints and can clear the workflow-clarity cap of 3.
Move web-interface features (My NCBI, saved searches, RSS, clipboard, export formats) into a reference file or fold them into common_queries.md so SKILL.md stays an overview, lifting progressive_disclosure toward 5.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient domain-specific content (field tags, MeSH syntax, E-utility endpoints, rate limits) that Claude would not reliably know, but it could be tightened: rate limits are stated three times (sections 4, Tips, Limitations), search-history/clipboard expiry is stated twice, the 'Working with Reference Files' section repeats the per-section 'When to consult' lists, and the opening explains what PubMed is. Fits 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than the 'minor instances' of anchor 4. | 3 / 5 |
Actionability | Mostly executable guidance: a runnable requests-based ESearch/EFetch snippet, concrete query examples with field tags, exact URL patterns, and grep patterns for the reference files. Minor gaps keep it below 5 — the EFetch example omits error handling, the ECitMatch and 'Batch Export' blocks are bare format strings rather than runnable code, and no workflow shows checking the JSON response for errors. | 4 / 5 |
Workflow Clarity | Five workflows are clearly sequenced, but validation is implicit or absent: the batch API workflow says 'Implement rate limiting and error handling' with no checkpoint (no response status check, no empty-idlist or error-field handling, no retry guidance). Per the rubric, missing validation steps in batch operations caps workflow clarity at 3, which takes precedence over the otherwise clean sequencing. | 3 / 5 |
Progressive Disclosure | Good structure with three real, one-level-deep reference files (verified present in references/), each signaled inline with 'When to consult' lists plus grep patterns and a summary section. Below 5 because some content that belongs in references is inlined in a ~450-line body (web-UI features like My NCBI, RSS feeds, search history, clipboard, export formats, support resources) and the reference pointers are duplicated between per-section cues and the 'Working with Reference Files' section. | 4 / 5 |
