social-auto-upload is an automation tool for uploading and scheduling videos across social media platforms including Douyin, Bilibili, Xiaohongshu, TikTok, and YouTube. Content creators and operators use it for repeatable multi-platform publishing, while its catalogue skills expose these upload workflows to coding agents.
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 | $0.00067 | $0.01406 |
| Opus 5.5 | $0.00027 | $0.00562 |
| Sonnet 5.5 | $0.00013 | $0.00281 |
| Haiku 4.5 | $0.00007 | $0.00141 |
Grade A, and why
dayu-upload 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
大鱼号发布
使用 sau dayu，不另写一套网页发布逻辑。先执行 sau dayu --help，具体参数以 upload-video --help、upload-article --help 和 verify --help 为准。仓库环境在项目根目录运行；Windows 未将命令加入 PATH 时用 .\.venv\Scripts\sau.exe。不要依赖固定测试账号或本机路径。
账号与输入
- 使用已有账号时执行
sau dayu check --account <本地账号名>。首次使用或登录失效时执行sau dayu login --account <本地账号名> --expected-name "用户指定的大鱼号名称"，让用户在打开的 Chrome 中登录。CLI 会绑定发布主体，拒绝错号。 - 视频必须提供
--file、--title、--thumbnail、--category、--source。视频至少 5 秒；标题 5–60 字（英文按半字）；封面最大 5 MB。分类从 CLI 的 choices 中选择，不能猜测页面外的分类。 - 文章必须提供
--title、--content-file、--source。标题 5–50 字（英文按半字并向上取整），正文为 UTF-8 HTML/Markdown/TXT 文件，最多 2 万字。长文放在文件里，不拼进命令行。图片使用本地路径，相对路径以正文文件所在目录为起点，每张最大 5 MB。 - 信息来源必须按实际内容选择：
无需标注、AI生成、虚构演绎、营销信息、转载、个人观点、不适宜未成年人。转载必须同时提供--source-url "https://原文地址"，其他来源不传原文链接。
命令
sau dayu upload-video --account <本地账号名> --file "视频.mp4" --title "用户的视频标题" --category "科技" --source "无需标注" --thumbnail "封面.jpg"
sau dayu upload-article --account <本地账号名> --title "用户的文章标题" --content-file "文章.html" --source "无需标注" --cover-indices 1
以上会实际发表；素材、主体及发表意图沿用用户已给出的授权。仅要求检查准备时增加 --prepare-only：它会上传素材、填写表单并保存本地截图，不发表，也不保存可恢复草稿。
Markdown 首次使用需要 Node.js 22+ 并执行 sau article setup。在文章命令中传 --content-file "文章.md" --theme modern，主题可选 default/grace/simple/modern/plain，默认 default。HTML/TXT 不传 --theme。可先使用 sau article render --content-file "文章.md" --theme modern --output "预览.html" 本地渲染。大鱼号采用兼容排版，保留文字颜色、背景和近似字号；圆角、精确字体与间距不保证原样。最终发表前会核对服务端主题预览。
视频选填 --desc、逗号分隔的 --tags；文章选填 --author、--cover-indices 1 或 --cover-indices 1 3 2，封面序号从正文图片顺序的 1 开始，三封面须各不相同。文章没有分类和标签字段。竖版封面、素材库、文档导入、正文视频和独立保存草稿尚未接入；不要声称命令已支持。
定时
只有用户要求定时才增加 --schedule "YYYY-MM-DD HH:MM"；不传默认立即发表。时间固定按**北京时间 Asia/Shanghai（UTC+8）**解释，须在当前时间 2 小时后至 7 天内，分钟为 5 的倍数。视频和文章用同一参数。向用户说明时区；缺少具体时间或存在歧义时先明确时间，不擅自取整或改成立即发表。预留上传和处理时间，填表时仍会校验范围。
平台确认本次作品及保存的预定时间后即为定时安排成功，不等待到点、审核或公开访问，不把“定时安排成功”说成“已公开”。平台审核可能使实际公开时间延后。
结果与中断
保留命令输出的结果文件和作品 ID。立即发表以最终业务确认成功为完成，审核中也已提交成功；定时必须确认原作品及预定时间。
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

dayu-upload is a skill published in the GitHub repository dreammis/social-auto-upload (15,697 stars, last pushed today), licensed MIT. It adds 67 tokens to every session and 1,406 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-22.
