Conciseness

The router is lean with no padding or explanations of known concepts, but minor duplication could be trimmed: section 3 repeats section 4's pointer to references/script-usage.md, and the inline DOI-metadata policy ("refetch the record by PMID or verify it against the publisher") restates guidance already in script-usage.md and ris-endnote.md — matching anchor 4's "minor instances that could be trimmed" rather than anchor 5's every-token-earns-its-place.

Actionability

Concrete direction throughout — exact paths ("Read manifest.yaml", "static/core/principles.md"), a specific flag ("pass it to the script as --scope"), a concrete threshold ("more than ~10 segments"), and all seven workflow steps enumerated by name — with the executable detail (full flag list, batch commands) deliberately one level deep in references, fitting anchor 4's mostly-executable-with-minor-gaps rather than anchor 3's missing key details.

Workflow Clarity

The four-step routing protocol is clearly sequenced, the seven steps are enumerated with named validation checkpoints ("evaluate support conservatively", "validate complete structured author metadata") and a PMID-refetch feedback loop, so the batch-operation cap is not triggered; it falls short of anchor 5 only because detailed validation and error-recovery procedures are deferred to reference files rather than stated inline.

Progressive Disclosure

The four references/ files are well signaled with explicit on-demand conditions, but the router's primary load path is broken as bundled: "manifest.yaml", "static/core/principles.md", "static/core/workflow.md", and "static/core/chinese-mode.md" do not exist in the provided bundle, so the first instruction cannot be executed — a structural gap beyond anchor 4's "minor organization gaps", though well above anchor 2's minimal structure.

Specificity

Names the domain and several concrete actions — "Find and verify Nature/CNS-family literature", "claim-to-source mapping", "reference-manager export" — but coverage has minor gaps (segmentation, support grading, and review artifacts are unmentioned), matching anchor 4 rather than the comprehensive anchor 5 and clearly above the 1-2-action anchor 3.

Completeness

Explicitly answers both what ("Find and verify Nature/CNS-family literature supporting manuscript claims, with claim-to-source mapping and reference-manager export") and when ("Use for Nature系列引用、CNS支撑文献、分段补引用 when this journal scope is requested"), with concrete trigger phrases and a clear negative boundary ("use broader literature search for unrestricted sources").

Trigger Term Quality

Triggers "Nature系列引用、CNS支撑文献、分段补引用" and "when this journal scope is requested" are natural phrases the target user would say, but common English variations ("citations", "references", "supporting literature", "Cell", "Science") are missing, so it sits just below the comprehensive-synonyms anchor 5.

Distinctiveness Conflict Risk

The "Nature/CNS-family" journal scoping carves a clear niche with distinct bilingual triggers, and the explicit delegation "use broader literature search for unrestricted sources" minimizes overlap with general literature-search skills — a clean match for anchor 5.
