The description names the domain (patent specifications) and one action (write detailed embodiment descriptions), but does not list multiple concrete actions such as drafting claims, generating figures descriptions, or structuring sub-embodiments.

Clearly answers both 'what' (write detailed embodiment descriptions for patent specifications) and 'when' (explicit 'Use when' clause with specific trigger phrases and a conceptual trigger scenario).

Includes strong natural trigger terms in both Chinese and English: '撰写实施例', 'write embodiment', '实施例描述', 'detailed description', and the conceptual trigger 'describe how to practice an invention'. Good bilingual coverage of terms users would actually say.

The combination of patent-specific terminology, bilingual Chinese/English triggers, and the narrow focus on embodiment descriptions makes this highly distinctive and unlikely to conflict with other skills.

The skill is mostly efficient and contains domain-specific knowledge Claude wouldn't inherently know (patent embodiment writing conventions, reference numeral formatting, US best mode requirement). However, some sections are somewhat verbose — the repeated emphasis on 'no experimental data' with multiple examples could be consolidated, and the explanatory framing ('they are the patent equivalent of experiment sections') adds minor padding.

The skill provides highly concrete, actionable guidance: specific formatting rules for reference numerals (first mention vs. subsequent), exact output file paths, table templates for planning and verification, example text patterns for opening paragraphs and variations, and clear examples of correct vs. incorrect embodiment language. The pseudocode example and step descriptions are copy-paste ready templates.

The 6-step workflow is clearly sequenced with logical progression: plan → write → integrate numerals → verify claim support → handle special cases → output. Step 4 provides an explicit verification/validation checkpoint (claim support verification table) with a feedback loop ('If any claim element lacks embodiment support, add the necessary description'), which is critical for this type of document generation task.

The skill references input files from a clear directory structure (patent/INVENTION_DISCLOSURE.md, patent/CLAIMS.md, patent/figures/numeral_index.md) and specifies output location, showing awareness of a broader system. However, all content is inline in a single file with no references to supporting documents for advanced topics (e.g., detailed reference numeral conventions, claim type-specific guidance), and the file is fairly long — some sections like the Key Rules could potentially be separated.
