Conciseness

The body is lean and imperative throughout — source-ID schemes ("P001... for paper text blocks"), support-state enums, and guardrails ("Never infer inventorship, ownership, unpublished implementation details...") with zero tutorial-style explanation of concepts Claude already knows. Every token carries a rule or a pointer, matching the 5 anchor; there is no padding to push it down to 4.

Actionability

Concrete guidance is present (source ID formats, allowed support states, copy-paste bash commands for validate/build), but the core of the workflow delegates to files that do not exist in the bundle: "Read `manifest.yaml`, then read every file under `always_load`", "complete the stages in `static/core/workflow.md`", and "`static/core/output-contract.md`" — none of these paths resolve, leaving key execution details missing per the 3 anchor. The commands that are present are executable, which keeps it above anchor 2's high-level-hints level.

Workflow Clarity

A clear five-section sequence with explicit validation gates ("Resolve all validation `ERROR` findings. Review every `WARNING` against the source"), stage gates before formal claims, and an explicit failure labeling rule ("Label the result `incomplete draft`"). It falls short of the 5 anchor because the actual gate definitions and quality thresholds live in the missing `static/core/workflow.md` and `static/core/output-contract.md`, so the checkpoints the sequence relies on cannot actually be followed — a material gap beyond "minor validation gaps".

Progressive Disclosure

The router pattern itself is sound — SKILL.md stays an overview and points to `references/draft-schema.md`, `references/disclosure/disclosure_self_check.md`, and named scripts, all one level deep and clearly signaled. However, per the actual bundle structure, four referenced navigation paths (`manifest.yaml`, `static/core/workflow.md`, `static/core/output-contract.md`, `static/fragments/task/*.md`) are absent, so the primary navigation mechanism (manifest-driven loading) is broken rather than merely imperfectly organized, which fits the 3 anchor better than 4.

Specificity

Names concrete actions and deliverables — "Turn research papers or inventor materials into evidence-grounded Chinese invention patent drafts and technical disclosures" plus "Chinese DOCX patent packages" and "现有技术对比" — but each action is a single transform verb rather than the multiple distinct operations of the 5 anchor (extract/fill/merge/convert). It is well above anchor 3, which expects only 1-2 concrete actions with no breadth.

Completeness

Clearly answers both: what — "Turn research papers or inventor materials into evidence-grounded Chinese invention patent drafts and technical disclosures" — and when — "Use for 技术交底书、专利撰写、现有技术对比 and Chinese DOCX patent packages", with a concrete negative boundary ("not general manuscript writing") reinforcing the trigger. This matches the 5 anchor's pattern of explicit what plus concrete trigger phrases, including an exclusion that anchor examples lack.

Trigger Term Quality

Strong natural trigger terms a Chinese-patent user would actually say: "技术交底书", "专利撰写", "现有技术对比", "Chinese DOCX patent packages", "patent drafts". Missing a few common variations such as "专利申请", "权利要求", or English equivalents like "patent application", keeping it just short of the comprehensive synonym/extension coverage of the 5 anchor.

Distinctiveness Conflict Risk

A clear niche — Chinese invention patent drafting from research materials — with natural-language and language-specific triggers (Chinese deliverable names) plus an explicit exclusion ("not general manuscript writing") that prevents overlap with generic writing/document skills. Minimal conflict risk, matching the 5 anchor.
