Conciseness

The body is a lean eight-item checklist with no padded explanations of what a literature review or PRISMA is; it assumes Claude's competence and every line carries an instruction, matching the score-3 "lean and efficient; every token earns its place" anchor.

Actionability

It provides concrete named elements ("Semantic Scholar, arXiv, OpenAlex"; "Extract: method, dataset, metrics, key findings"), but offers no copy-paste-ready specifics such as sample search query strings, an inclusion/exclusion criteria template, or an extraction table, fitting the score-2 anchor of "some concrete guidance but incomplete" rather than fully executable examples.

Workflow Clarity

The eight steps are clearly sequenced (1–8), but screening is a batch operation and no validation/verification checkpoint is present (e.g., re-screening borderline papers, consistency checks), so per the capping rule workflow clarity is held at the score-2 anchor rather than reaching the score-3 explicit-validation anchor.

Progressive Disclosure

This is a single-purpose skill under 50 lines with no bundle files; the content is well-organized under a clear heading with a numbered list, so under the simple-skills scoring note progressive disclosure earns a 3 without external file references.

Specificity

Quotes "Structured methodology for comprehensive literature review following PRISMA guidelines" and "literature search and screening stages" name the domain and a couple of actions (search, screening), but no enumerated concrete actions like "search databases, screen papers, extract findings, synthesize gaps", matching the score-2 anchor rather than the multi-action score-3 example.

Completeness

It states the "what" ("Structured methodology for comprehensive literature review following PRISMA guidelines") and an explicit "when" trigger ("Use during literature search and screening stages"), satisfying the score-3 anchor requiring both what and when with an explicit 'Use when'-equivalent clause.

Trigger Term Quality

Phrases "literature review" and "literature search" are natural terms a user would say, but coverage is thin — common variations like "related work", "prior work", "research survey", or "systematic survey" are absent, fitting the score-2 anchor of "some relevant keywords but missing common variations".

Distinctiveness Conflict Risk

The PRISMA-guided systematic literature review niche with "literature search and screening stages" triggers is a well-defined, distinct domain unlikely to fire for unrelated skills, matching the score-3 "clear niche with distinct triggers" anchor.
