The body is lean and assumes competence — it jumps straight to the locale directory path and a single concrete `ls app/src/locales/*.yml` command with no padding or explanation of concepts Claude already knows, matching the 'lean and efficient; every token earns its place' anchor; it does not drop to 2 because there is no unnecessary explanation to trim.

It gives concrete, executable guidance for viewing languages (the exact directory path and a runnable `ls` command), but the skill's stated purpose includes adding and updating translations, for which no concrete executable steps or examples are provided, matching 'some concrete guidance but incomplete'; it is not level 1 because real executable code is present, and not level 3 because the core add/update workflow lacks copy-paste-ready instructions.

It sequences a sensible first step ('在添加或修改翻译前，先查看...目录'), but editing locale files is a batch operation across multiple files with no validation/verification checkpoint (e.g., checking for missing keys or YAML validity), so per the rubric's batch-operation guidance workflow clarity is capped at 2; it is above level 1 because a clear prerequisite sequence is given.

This is a simple skill well under 50 lines with no external bundle references and clean section organization ('翻译文件位置', '查看当前支持的语言'), so per the scoring_notes for simple skills progressive disclosure scores 3; there are no nested references to penalize.

It names the domain ('管理多语言翻译') and three actions ('添加新翻译、更新现有翻译或了解翻译系统结构'), but the actions are broad categories rather than a comprehensive list of concrete operations, matching the 'names domain and some actions, but not comprehensive' anchor; it does not reach level 3 because no concrete sub-actions (e.g., editing a specific YAML key, syncing across locales) are enumerated.

It explicitly states both what it does ('指导如何在 Project Graph 项目中管理多语言翻译') and when to use it ('当需要添加新翻译、更新现有翻译或了解翻译系统结构时使用此技能'), with an explicit 'Use when'-equivalent trigger clause, matching the level-3 anchor; it is not capped at 2 because the trigger guidance is explicit rather than implied.

Phrases like '添加新翻译、更新现有翻译或了解翻译系统结构' are relevant triggers a user might say, but the coverage is limited to these three exact phrasings and lacks common natural variations (e.g., 'i18n', 'localization', 'locale files', 'missing translations'), so it sits at 'some relevant keywords but missing common variations' rather than the broad coverage of level 3.

It is scoped to a specific project ('Project Graph 项目') and a narrow niche (multi-language translation management), giving it a clear niche with distinct triggers unlikely to conflict with other skills; it does not score lower because the project + translation domain boundary is explicit and distinctive.
