Conciseness

The body has several padded or duplicated sections: the 'Screening and Selection' heading appears twice and the first instance (lines 104-108) repeats the Search Strategy list verbatim; 'How to generate figures' and 'How to generate schematics' cover the same command; the closing 'Summary' section recaps every earlier section; and lines like 'This is not optional. Literature reviews without visual elements are incomplete' plus lists of tools Claude already knows (matplotlib, seaborn) add tokens without new information. This is noticeably verbose with several unnecessary sections (anchor 2), though not the pervasive concept-explanation padding of anchor 1.

Actionability

Concrete executable commands appear throughout: 'python scripts/generate_schematic.py "your diagram description" -o figures/output.png', 'python scripts/verify_citations.py', 'python scripts/generate_pdf.py --check-deps', and install snippets for parallel-cli, uv, and pandoc/texlive. Minor gaps keep it below 5: no worked example of an actual 'parallel-cli search' invocation with arguments inline, and database-specific query commands are deferred to references rather than shown.

Workflow Clarity

The seven-phase workflow is clearly sequenced with per-phase purposes and pointers to the full reference, and validation checkpoints are present ('Verify all citations: Run verify_citations.py', '--check-deps', 'Record every search string and date'). It is not a 5 because explicit fix-and-retry feedback loops (e.g., what to do when citation verification or dependency checks fail) are not described, and there is a literal copy-paste duplication of the Screening and Selection list that muddies that step.

Progressive Disclosure

References are well signaled and all real: links to references/core_workflow.md, search_and_citation.md, and example_workflow.md in the workflow section, plus a Bundled Resources inventory whose files all exist on disk, one level deep with no nesting. It falls short of 5 because substantial content that belongs in reference files is inlined in SKILL.md (the full Best Practices lists, the Integration-with-Other-Skills catalog, and the External Resources link dump).

Specificity

The description lists multiple concrete actions with named specifics: 'Conduct comprehensive, systematic literature reviews using multiple academic databases (PubMed, arXiv, bioRxiv, Semantic Scholar)' and 'Creates professionally formatted markdown documents and PDFs with verified citations in multiple citation styles (APA, Nature, Vancouver)'. Coverage spans searching, synthesis, citation verification, and output generation, matching the comprehensive anchor; it is not score 4 because there are no meaningful gaps in the action inventory.

Completeness

Both what and when are explicitly answered: 'Conduct... literature reviews... Creates professionally formatted markdown documents and PDFs' states the what, and 'This skill should be used when conducting systematic literature reviews, meta-analyses, research synthesis...' gives a concrete explicit trigger clause. This matches the score-5 anchor exactly; score 4 would require a weaker or less explicit 'when'.

Trigger Term Quality

Natural trigger phrases are present ('systematic literature reviews, meta-analyses, research synthesis, or comprehensive literature searches') and would be said by real users, but a few common variations are missing (e.g., 'survey of the field', 'related work section', 'state-of-the-art review'). Good coverage without being comprehensive, so it sits between the 4 and 5 anchors, clearly above 3.

Distinctiveness Conflict Risk

The literature-review/meta-analysis niche is well staked out with distinct triggers, but phrases like 'comprehensive literature searches' across 'scientific, and technical domains' create minor overlap risk with general research or web-search skills. Mostly distinct with minor overlap, which is the 4 anchor rather than the minimal-conflict 5.
