Test report

Verdict: Tested · Works
Score: 8.8/10
Tested: Jul 29, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · 9b02d39

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 29, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Drafted claims plus an abstract for the same 45-line Python risk-scoring module twice and ran a compliance checker over both: the no-skill draft came out at 314 abstract characters (CNIPA's hard limit is 300), used two banned vague words, and put an illegal 'claims 1 to 3' back-reference in a dependent claim, while the skill-guided draft landed at 261 characters, zero vague words, quoted all five real function names and nine exact constants from the source, and gave every parameter a range plus a preferred value. It also self-reported the one checklist item it could not satisfy. The catch: the repo ships no main.tex and its recommended preamble never defines the \inventionTitle, \inventor, \applicant and \filingDate macros its own request-form template uses, so the final 'compile to PDF' step needs hand-built scaffolding.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What CN Patent Drafter does

Drafts and compliance-checks the five documents of a Chinese invention patent application (request form, abstract, claims, specification, drawings) as LaTeX sources, using a bundled 36-item CNIPA 2025-2026 checklist and four placeholder templates. Triggers on Chinese-language requests mentioning 发明专利, 权利要求, 说明书, CNIPA, paragraph markers like [0001], or edits to .tex files under a patent-tex project. Scoped to CN invention patents only; software copyright, utility model and design patents are explicitly out of scope.

How to install CN Patent Drafter

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
