Conciseness

The ~100-line body is lean directive prose with zero concept explanations, no library comparisons, and no padding — e.g., "Create stable source IDs before drafting: `P001...` for paper text blocks" teaches only what Claude could not invent itself. Every token carries an instruction, matching the lean anchor; there is nothing to trim for a higher fit since 5 is the top.

Actionability

Concrete, executable guidance dominates: exact commands (`python scripts/validate_patent_draft.py draft.json`, `python scripts/build_patent_package.py draft.json --output-dir outputs --prefix patent`), defined ID schemes (P001/E001/F001/C001), and a closed enum of support states (explicit/inherent/needs-confirmation/unsupported). Not a 5 because some steps remain pointers rather than invocations — "render Mermaid/Word outputs with `scripts/disclosure/mermaid_render.py`" gives no arguments, and "run the internal checks in `references/disclosure/disclosure_self_check.md`" delegates without stating the checks; not a 3 because the majority of the workflow is copy-paste executable.

Workflow Clarity

The multi-step process is explicitly sequenced with stage gates ("Do not move to formal claims until the source map, terminology ledger, inventories, evidence ledger, and invention concept pass their gates") and a validate-before-delivery section with explicit commands, ERROR-level blocking ("Resolve all validation `ERROR` findings"), WARNING review, and an incomplete-draft label as the failure path — matching the anchor with explicit validation steps, feedback loops, and checklists. The lower anchors all lack either the sequence detail or the checkpoints present here.

Progressive Disclosure

The router design (manifest-driven conditional loading, one-level-deep references like `references/draft-schema.md` and `static/fragments/task/*.md`) is the right pattern and all references are clearly signaled by full path. However, scored against the actual bundle: the core navigation targets cited in sections 1, 3, and 5 — `manifest.yaml`, `static/core/workflow.md`, `static/core/output-contract.md`, and both `static/fragments/task/*.md` files — do not exist in the provided bundle, so step 1 fails immediately for a reader; only the section 4–5 paths (draft-schema, disclosure_self_check, mermaid_render, validate/build scripts) resolve. Not a 2 because the SKILL.md itself is well split rather than inlining bulk content; not a 4 because unresolvable primary navigation paths are more than a minor organization gap.

Specificity

Names several concrete deliverables — "evidence-grounded Chinese invention patent drafts and technical disclosures" plus "Chinese DOCX patent packages" — going beyond a single generic action. Not a 5 because the actions are summarized at the output level without listing intermediate capabilities (claims, specifications, prior-art comparison workflows), leaving minor coverage gaps; not a 3 because it names multiple specific outputs rather than only one or two bare actions.

Completeness

Explicitly answers both questions: the what is "Turn research papers or inventor materials into evidence-grounded Chinese invention patent drafts and technical disclosures" and the when is the concrete "Use for 技术交底书、专利撰写、现有技术对比 and Chinese DOCX patent packages" trigger clause, reinforced by a negative boundary ("not general manuscript writing"). This matches the anchor with clear what, explicit when, and concrete trigger phrases, so nothing below 5 fits better.

Trigger Term Quality

"Use for 技术交底书、专利撰写、现有技术对比 and Chinese DOCX patent packages" supplies natural trigger terms a user needing this skill would actually say, including the native-language phrases. Not a 5 because common variations like 专利申请, 权利要求, or 'patent draft/claims' are missing; not a 3 because coverage goes well beyond a single keyword and includes both Chinese and English phrasing.

Distinctiveness Conflict Risk

The niche — Chinese invention patent drafting from research papers — is highly specific, and the explicit exclusion "not general manuscript writing" reduces overlap with generic writing skills. Clear distinct triggers with minimal conflict risk, matching the top anchor.
