The body is mostly lean and assumes Claude's competence, but the '调用方式' and '使用示例' sections contain near-duplicate code blocks that could be tightened into one. It is not score 3 because of that redundant example, and not score 1 because there is no padded explanation of concepts Claude already knows.

Provides fully executable, copy-paste-ready code with all four parameters and a complete parameter table (type, required, default, description) plus the return value. It is not score 2 because the code is real and complete rather than pseudocode or missing key details.

This is a simple single-task skill with one unambiguous action (call audio2txt with a path and credentials), and the 5MB constraint is flagged; no destructive or batch operation is involved so no validation checkpoint is required. It is not score 2 because the single action is unambiguous and the skill is simple.

The body is short and well-organized into clear sections (功能描述, 调用方式, 参数说明, 返回值) with no bundle files and no need for external references. It is not score 2 because the organization is clear and self-contained with no nested references.

Names the domain ('从音频文件中提取文字') and one concrete action, but does not list multiple specific concrete actions like the anchor-3 example. It is not score 1 because it is not vague, and not score 3 because it stops at a single action rather than enumerating several.

Explicitly states what it does ('从音频文件中提取文字') and when to use it ('当用户提到...时使用'), an explicit Use-when clause. It is not score 2 because the trigger is explicit rather than merely implied.

Covers natural terms users would say — '音频转文字、语音识别、ASR、音频转字幕' — giving good coverage of common variations. It is not score 2 because it lists several natural phrasings rather than a single keyword with missing variations.

A clear niche (Tencent Cloud speech-to-text) with distinct ASR triggers unlikely to conflict with other skills. It is not score 2 because the domain and triggers are specific enough to avoid overlap with similar skills.
