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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00034 | $0.00415 |
| Opus 5 | $0.00017 | $0.00208 |
| Sonnet 5 | $0.00007 | $0.00083 |
| Haiku 4.5 | $0.00003 | $0.00042 |
Grade A, and why
video-generate 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 3d 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
Video Generate
适用场景
当需要根据文本描述生成视频时，使用该技能。支持通过首帧图片控制视频起始画面，首帧可以是 URL 或本地文件路径。
使用步骤
- 准备目标文件名（如
output.mp4）和清晰具体的prompt。 - (可选) 准备首帧图片，可以是 HTTP URL，也可以是本地文件路径（脚本会自动转为 Base64）。
- 运行脚本
python scripts/video_generate.py <filename> "<prompt>" [first_frame]。运行之前cd到对应的目录。 - 脚本将输出视频的 TOS URL 并自动下载到指定文件。
认证与凭据来源
- 优先读取
MODEL_VIDEO_API_KEY或ARK_API_KEY环境变量。 - 若未配置，将尝试使用
VOLCENGINE_ACCESS_KEY与VOLCENGINE_SECRET_KEY获取 Ark API Key。
输出格式
- 控制台输出生成的视频 URL。
- 视频文件将被下载到指定路径。
示例
纯文本生成：
python scripts/video_generate.py "cat.mp4" "一只可爱的猫"
带首帧图片生成（URL）：
python scripts/video_generate.py "dog_run.mp4" "一只小狗在草地上奔跑" "https://example.com/dog_start.png"
带首帧图片生成（本地文件）：
python scripts/video_generate.py "my_video.mp4" "图片中的人物动起来" "/path/to/local/image.jpg"
What ships with it
2 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.

video-generate is a skill published in the GitHub repository bytedance/agentkit-samples (449 stars, last pushed 3d ago), licensed Apache-2.0. It adds 34 tokens to every session and 415 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 2026-09-03.

sn-image-base
Base-layer skill for the SenseNova-Skills project, providing low-level APIs for image generation, recognition (VLM), and text optimization (LLM). This skill does not preprocess inputs; it only calls backend services and returns results. This skill is not user-facing and is intended for upper-layer skills only.
