Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00094 | $0.02429 |
| Opus 5 | $0.00047 | $0.01215 |
| Sonnet 5 | $0.00019 | $0.00486 |
| Haiku 4.5 | $0.00009 | $0.00243 |
Grade A, and why
douyin-video-downloader scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

- 列出可用视频清晰度/码率候选
- 按指定清晰度下载 MP4
- 下载视频时同步下载封面图，默认选择中档尺寸
- 支持单独下载封面图
- 下载抖音音乐详情接口暴露的直接音频文件
- 从采集库批量下载直接音频
- 用本地 SQLite 采集库记录用户、列表页、视频、统计和音乐信息

- 从采集库导出 JSON/CSV，或按批次下载库里的视频
- 默认尽量使用无水印播放地址
使用方法
先确定 {SKILL_DIR} 为本 SKILL.md 所在目录。
查看视频信息、清晰度和封面候选
node {SKILL_DIR}/douyin-video.js info "抖音分享链接" --cover-size medium
下载默认清晰度
node {SKILL_DIR}/douyin-video.js download "抖音分享链接" -o ./videos
默认选择 best，即脚本能识别到的最高质量候选。
视频下载会同时下载封面图，并把视频、封面和 metadata 路径都写入 metadata JSON。
指定清晰度下载
node {SKILL_DIR}/douyin-video.js download "抖音分享链接" --quality best -o ./videos
node {SKILL_DIR}/douyin-video.js download "抖音分享链接" --quality 720p -o ./videos
node {SKILL_DIR}/douyin-video.js download "抖音分享链接" --quality 0 -o ./videos
--quality 支持：
best：最高质量lowest：最低质量720p/1080p这类清晰度标签- 数字序号：使用
info输出中的候选序号 ratio、format、gear_name等候选标签的部分匹配
指定封面尺寸下载
node {SKILL_DIR}/douyin-video.js download "抖音分享链接" --cover-size medium -o ./videos
node {SKILL_DIR}/douyin-video.js download "抖音分享链接" --cover-size origin -o ./videos
node {SKILL_DIR}/douyin-video.js download "抖音分享链接" --cover-size 0 -o ./videos
node {SKILL_DIR}/douyin-video.js cover "抖音分享链接" --cover-size medium -o ./videos
--cover-size 支持：
medium：默认，中档尺寸small：较小封面候选large/best：按返回宽高选择较大封面origin：原始封面字段raw：原始/未处理封面字段dynamic/animated：动态封面候选gaussian/blur：模糊封面候选- 数字序号：使用
info输出中的封面候选序号 none：不下载封面
下载直接音频
node {SKILL_DIR}/douyin-video.js audio "抖音分享链接" -o ./audios
audio 命令会先解析视频对应的 music.mid/id，再请求抖音音乐详情接口获取 music.play_url 并下载原始音频文件。没有直接音频地址时会报错，不会从 MP4 中抽取音频。
视频、封面和音频命令会合并写入同一个 metadata JSON，不会因为后执行音频而覆盖之前的视频或封面文件路径。
创建 SQLite 采集库
node {SKILL_DIR}/douyin-video.js db-init --db ./douyin_collection.sqlite
采集库包含：
users：用户资料crawl_pages：每次列表页接口响应videos：视频标题、链接、封面、时长、发布时间等video_stats：点赞、评论、收藏、转发、播放、下载等统计字段music：音乐 ID、标题、作者、时长、直接音频地址等video_downloads：后续批量下载的成功/失败状态、文件路径和错误信息media_downloads：音频等媒体文件的成功/失败状态、文件路径和错误信息
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
