The body is mostly lean with executable code and no concept explanations, but sections like '所属分类' (a path) and '原始函数' plus a restated '功能描述' add non-actionable padding; not score 3 because those tokens do not earn their place.

It provides fully executable Python in '调用方式' and '使用示例', a concrete parameter table, and a return type — copy-paste ready guidance.

This is a simple single-task skill whose single action (call transtools) is unambiguous; per the simple-skills note, workflow clarity scores 3 without needing multi-step validation.

Under 50 lines with no external references needed and clearly organized sections (功能/调用/参数/返回/示例), meeting the simple-skill progressive disclosure criterion of well-organized sections.

The phrase '将内容从一种语言翻译为另一种语言' names the translation domain and a single action but does not list multiple concrete actions, matching the 'names domain and some actions, but not comprehensive' anchor.

It states what it does ('将内容...翻译为另一种语言') and gives an explicit 'when' clause ('当用户提到...时使用'), clearly answering both what and when.

The trigger list '翻译、中英互译、多语言翻译、自动翻译' covers several natural phrasings a user would actually say, matching the 'good coverage of natural terms' anchor; not score 2 because it goes beyond a single keyword.

Translation is a distinct niche with specific triggers that are unlikely to conflict with other skills, matching the 'clear niche with distinct triggers' anchor.
