Conciseness

The body is mostly substantive and domain-specific, but the "Key Rules" section substantially duplicates guidance already given in the workflow (antecedent basis "a"/"the", open "comprising", no result-to-be-achieved language, draft independent claims first), and the constants block is verbose. Not a 4 because the redundancy is more than minor; not a 2 because most content earns its place and patent-specific terms are not general knowledge Claude is assumed to have.

Actionability

Provides copy-paste-ready material: jurisdiction-specific claim-format templates (e.g. CN "一种[主题]，其特征在于，包括：..."), dependent-claim formats, a complete mcp__codex__codex examiner call with model and reasoning config, quality-check checklists, and an output template with a summary table. Not below 5 because the common cases are concretely covered with executable templates.

Workflow Clarity

Seven steps are clearly sequenced with an explicit validation checkpoint (cross-model examiner review in Step 5), a feedback loop (Step 6 revision loop with re-submission via threadId up to MAX_CLAIM_REVISION_ROUNDS), and checklists (per-claim quality checks, claim-to-specification mapping). Matches the anchor requiring explicit validation, feedback loops, and checklists.

Progressive Disclosure

The "Shared References" section signals one-level-deep references with per-file purposes, but all four referenced paths (../shared-references/patent-writing-principles.md, patent-format-cn/us/ep.md) do not exist — no shared-references directory or bundle files are present, so the detailed materials the overview points to are unavailable. Not a 4 because broken references break the navigation promise; not a 2 because the inline content is reasonably structured rather than a monolithic wall.

Specificity

Names the concrete domain and a single concrete action — "Draft patent claims for an invention" — but does not enumerate the multiple specific actions the skill performs (drafting independent/dependent claims, examiner review, revision), so it is not comprehensive. Not a 2 because the action is concrete rather than generic; not a 4 because only one action is listed.

Completeness

Explicitly answers both "what" ("Draft patent claims for an invention") and "when" ("Use when user says ... or wants to create patent claims") with concrete trigger phrases. Matches the anchor that requires both answered with concrete triggers.

Trigger Term Quality

Comprehensive coverage of natural trigger phrases across two languages — "撰写权利要求", "draft claims", "写权利要求书", "claim drafting", and "wants to create patent claims" — including synonyms a user would actually say. Not below 5 because no common natural phrasing is missing for this bilingual niche.

Distinctiveness Conflict Risk

Occupies a clear niche (patent claim drafting) with distinct bilingual triggers, so it is unlikely to fire for unrelated skills. The trailing "core skill of the patent pipeline" introduces minor overlap with sibling patent skills, but not enough to drop below 5.
