Conciseness

The body is lean and non-tutorialial, with no explanation of concepts Claude already knows. Minor over-explanation remains: the 任务目标 section restates the frontmatter, the 使用示例 uses a bureaucratic 功能说明/执行方式/关键参数 scaffold, and step 2 trails off with a vague "处理...". It is not 5 because these sections could be tightened, but well above 3 since there is no conceptual padding.

Actionability

The body provides a copy-paste-ready bash command with fully specified arguments and a worked example ("python scripts/generate_video_materials.py --theme ... --output_dir ./output") plus an enumerated list of output files. It is not 5 because step 2 contains an ellipsis placeholder ("调用 ... 处理...") and the required environment variables (COZE_LLM_BASE_URL / COZE_LLM_API_KEY) that the script depends on are never mentioned.

Workflow Clarity

The sequence (prepare inputs → run script → view outputs) is clearly listed, but there are no validation checkpoints for a batch operation that generates four output files; the 注意事项 items are advisories rather than verify/fix/retry loops. This matches anchor 3 ('steps listed but validation gaps') and is above 2 because the sequence and expected outputs are well defined.

Progressive Disclosure

The body is a genuine overview with one-level-deep references, each annotated with a 何时读取 (when to read) cue, and every referenced file exists in the bundle (references/*.md ×4 and scripts/generate_video_materials.py). It is not 5 because assets/output-templates/ (three template files) is never referenced or linked from the body, leaving part of the bundle undocumented.

Specificity

The description lists four concrete deliverables ("口播文案、分镜脚本、Veo2提示词及人物规范"), matching the 'several specific actions with minor gaps' anchor. It falls short of 5 because phrases like "一键生成" (one-click generation), "完美适配" (perfectly adapts), and "让视频创作更高效" (makes creation more efficient) are marketing fluff rather than concrete capabilities.

Completeness

The 'what' is explicit (generates a full material package of script, storyboard, Veo2 prompts, and character specs) and a 'when' is present ("在制作历史科学类3分钟科普短视频时"), so the missing-trigger cap of 3 does not apply. It is not 5 because the trigger is framed around creator personas rather than a crisp 'use when the user asks for X' phrase, and it is embedded in a promotional sentence rather than stated as explicit invocation guidance.

Trigger Term Quality

Terms like "历史科学类", "3分钟", "科普短视频", "口播文案", "分镜脚本", and "Veo2提示词" are natural phrases a creator would actually say. It is not 5 because common variations and synonyms (e.g., 短视频制作, 视频脚本, 科普文案) are missing, and it is well above 3 since coverage goes beyond one or two generic keywords.

Distinctiveness Conflict Risk

The niche is unmistakable — historical-science 3-minute explainer videos with Veo2 prompts and the 即梦 platform — giving it distinct triggers with minimal overlap with any other plausible skill.
