bytedance/agentkit-samples is a collection of examples and tutorials for Volcengine AgentKit, an AI-agent development platform for building, deploying, and operating agent applications. Developers use the samples to learn agent creation, multi-agent collaboration, memory, retrieval, MCP integrations, media generation, customer service, and other workflows. The catalogue skills provide agent workflows based on these examples.
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.

What it costs to keep this loaded
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 | $0.00042 | $0.00750 |
| Opus 5 | $0.00021 | $0.00375 |
| Sonnet 5 | $0.00008 | $0.00150 |
| Haiku 4.5 | $0.00004 | $0.00075 |
Grade A, and why
byted-ind-ecom-prompt-to-video 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 11d 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.
What it actually says
Seedance 2.0 文生视频/参考生成视频（byted-ind-ecom-prompt-to-video）
本 skill 用于调用火山方舟上的 Seedance 2.0 视频生成能力，支持：
- 文生视频（仅 prompt）
- 图生视频（首帧/首尾帧）
- 多参考生成（参考图片最多 9 张、参考视频最多 3 个）
使用方式
在 skill 目录下执行 scripts/generate.py。
参数
--prompt：视频文本提示词--first_frame：首帧图片（URL 或本地路径）--last_frame：尾帧图片（URL 或本地路径）--reference_images：参考图片（URL 或本地路径，最多 9 张）--reference_videos：参考视频（URL 或本地路径，最多 3 个）--resolution：分辨率（如720p、1080p）--ratio：画幅（如16:9、9:16、1:1、adaptive）--duration：时长（秒）
示例
文生视频：
python3 scripts/generate.py --prompt "A cute cat playing with a ball of yarn in a sunny room" --ratio 16:9 --duration 5
图生视频（首帧）：
python3 scripts/generate.py --prompt "The cat jumps" --first_frame "/path/to/cat.jpg" --ratio 16:9 --duration 5
多参考图片：
python3 scripts/generate.py --prompt "A scenic landscape" --reference_images "/path/to/img1.jpg" "/path/to/img2.jpg" --ratio 16:9
本地素材处理逻辑（重要）
- 本地图片：
- 在“可用 TOS”时会先上传到 TOS，再使用公网 URL 参与生成。
- 若无可用 TOS，则自动转为
data:<mime>;base64,...形式提交。
- 本地参考视频：建议直接提供公网 URL；如提供本地视频，需要可用 TOS 才能先上传转为公网 URL。
- 视频输出：
- 若可用 TOS，会尝试将生成视频转存到 TOS 并输出 TOS URL。
- 否则直接返回模型原始视频 URL（通常有时效，建议尽快下载或转存）。
环境变量
最低必需：
ARK_API_KEYSEEDANCE_EP_IDARK_BASE_URL（可选，默认https://ark.cn-beijing.volces.com/api/v3）
如需启用 TOS 上传/转存：
VOLC_ACCESS_KEYVOLC_SECRET_KEYTOS_ENDPOINTTOS_REGIONTOS_BUCKETTOS_UPLOAD_ENABLED（可选，默认true）
输出
脚本会轮询任务直到结束，并在终端输出：
Final Video URL: <url>
What ships with it
4 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.

byted-ind-ecom-prompt-to-video is a skill published in the GitHub repository bytedance/agentkit-samples (450 stars, last pushed yesterday), licensed Apache-2.0. It adds 42 tokens to every session and 750 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
