Conciseness

The body is dense and assumes competence — terse numbered principles, tables, and a compact pipeline diagram with no explanations of concepts Claude already knows. Minor trimming is possible (the 模式分派 table repeats reference paths already listed in the Reference 文件索引), so it fits the 4 anchor 'efficient; minor instances that could be trimmed' rather than the 5 anchor's every-token-earns-its-place.

Actionability

Concrete guidance throughout: an exact project file layout with per-file purposes, a decision table mapping inputs to modes, numeric QA thresholds (7.0/5.0), and quoted example user utterances. It falls short of 5 because the primary 9-step compose/revise flows are only pointed to, and the body's routing step "先读取 manifest.yaml" names a file that does not exist in the bundle, so a reader following it verbatim would stall.

Workflow Clarity

The QA pipeline is explicitly sequenced (Gate 2 → 1 → 3 → 4) with a stated rationale for the ordering, per-gear thresholds, and a bounded feedback loop ("总分<阈值 → 按低分维度定向回退（不超过 3 轮）") plus stop rules, matching the 5 anchor's clear sequence with validation steps and error-recovery loops. No destructive/batch operation is involved, so the ≤3 cap does not apply.

Progressive Disclosure

Structure is excellent — an overview body with a 20-row reference index giving per-file load conditions, all of which exist in references/ and are one level deep, matching the 5 anchor's pattern. However, two body instructions route through `manifest.yaml` and `templates/` ("按 manifest.yaml 的 templates.on_demand 路由从 templates/ 取空模板"), which are absent from the bundle, and scripts/build_proposal_docx.py is never mentioned — real navigation gaps that hold it at 4.

Specificity

"Compose, revise, or audit research proposals, opening reports, and research plans" lists three concrete verbs applied to three named artifact types, matching the 'several specific actions; minor gaps in coverage' anchor. It stops short of the 5 anchor's comprehensiveness — QA pipeline modes, review-paper support, and handoff-brief generation covered in the body are absent from the description.

Completeness

The 'what' is explicit ("Compose, revise, or audit research proposals...") and the 'when' is an explicit trigger clause with concrete phrases ("Use for 研究计划、开题报告、科研项目申请书"), satisfying the 5 anchor's both-what-and-when-with-concrete-triggers requirement; the 'Use for' clause also avoids the ≤3 cap for missing trigger guidance.

Trigger Term Quality

Natural terms are present bilingually ("research proposals", "opening reports", "research plans", plus 研究计划、开题报告、科研项目申请书), which is good keyword coverage with synonyms. A few natural terms users would say are missing (e.g., grant application/标书, proposal draft/修改意见), so it sits at the 4 anchor rather than 5's comprehensive coverage.

Distinctiveness Conflict Risk

The closing sentence "use nature-writing for general manuscript sections" actively demarcates the boundary with the closest related skill, and the niche (proposal/plan writing from supporting evidence, not general manuscripts) has distinct triggers, matching the 5 anchor's clear-niche-minimal-conflict example.
