Conciseness

The tool tables are token-efficient, but several 'Verified live' passages pad with testing-process narrative rather than instructions — e.g. "confirmed by re-running with a broader query and an empty-query call, both of which returned real, different, non-empty result sets" — and the Common Pitfalls section restates points already made in Sections 1 and 3. Inline time-sensitive facts ("Version: '1.53.3'", "2026-09-21" event) also fall outside a deprecated/old-patterns section.

Actionability

Gives exact tool names, exact parameter names with case-sensitivity warnings ("biotoolsID", "toolType", "package_name" ... "not `package`"), copy-paste-ready example calls with real outputs ("BioTools_search {\"q\": \"RNA-seq\", \"size\": 3}\" -> 6,081 total matches"), and per-question-type entry points ("start with BioTools_search"). This matches the fully-executable 5 anchor.

Workflow Clarity

The dispatch workflow is clear — the 'When to Use' section maps question types to resources, each section names which tool to start with, and 'Choosing Among the Five' gives an explicit fallback order ("try Bioconductor first ... fall back to CRAN"), with error-recovery loops like checking `count` and paging further, and retrying a broader TeSS query. It falls short of a 5 because the overall lookup sequence is never laid out as explicit ordered steps with validation checkpoints; the guidance is distributed across sections.

Progressive Disclosure

A single-level, well-organized document: clear section headers, consistent per-registry tables, and a summary 'Choosing Among the Five' table that aids navigation, with no nested or buried references. It scores 4 rather than 5 because at ~95 lines it exceeds the under-50-line simple-skill exception, and the per-registry 'Verified live' details are candidates for a separate reference file.

Specificity

Enumerates multiple concrete discovery targets — "bioinformatics software tool, biomedical REST API, R/Bioconductor package, CRAN package, or training material" — each mapped to a named registry with its search dimensions ("by keyword, EDAM topic, or EDAM operation"). Coverage across the skill's full scope is comprehensive, exceeding the "several specific actions; minor gaps" of a 4.

Completeness

Explicitly answers both: what ("Discover which ... exists for a task, before writing analysis code or building a pipeline", with the five covered registries) and when ("Use when someone asks ..."). Concrete trigger phrases match the 5 anchor exactly; it is not merely an implicit or partial 'when' as at 4.

Trigger Term Quality

Four verbatim natural trigger phrases ("is there an existing tool/package for X", "what software does [analysis]", "find an API for Y", "is there a tutorial on Z") plus natural nouns like "tutorial", "API", and "package" give comprehensive coverage of how users actually phrase these requests. No common variation is obviously missing for this domain.

Distinctiveness Conflict Risk

A clear niche — discovering existing bioinformatics resources across five named registries "before writing analysis code or building a pipeline" — with trigger phrases that would not fire for general coding, document, or data-retrieval skills. Overlap risk with adjacent tooluniverse skills is minimal because the discovery-vs-execution boundary is stated.
