generate-video

generate-video is a skill for Claude Code from FradSer/dotclaude. It costs 104 tokens per session (1,504 once invoked), scanned A, original, MIT.

A tool that creates short MP4 videos from text prompts or still images using Seedance on Volcengine Ark, an online video-generation service. It can use an opening image, an ending image, or reference images.

In plain words
What is it for?
Use it for text-to-video clips, animating a still image, morphing between first and last frames, and making product demos or motion graphics.
Why use it?
It turns a description or existing visual material into an asynchronously generated video, without requiring the user to animate every frame by hand.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

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.

Security

Grade A, and why

generate-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 22d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate_video.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Generate Video (Seedance on Volcengine Ark)

Turn a text prompt — optionally anchored by a first frame, a last frame, or reference images — into a short video. The script submits an async task, polls until it finishes, and downloads the .mp4. Generation takes a few minutes, so set expectations and let it run.

Prerequisites

  • uv available (self-contained uv run script; deps install on first run).

  • A Volcengine Ark key. Resolved progressively, so any one works:

    • export ARK_API_KEY=... in the shell, or
    • a .env file (checked in order: $PWD/.env, then ${CLAUDE_PLUGIN_ROOT}/.env), or
    • --api-key ... on the command line.

    CRITICAL -- Never paste the API key into chat or commit a .env. If the key is missing, the script prints exactly how to set it — relay that instead of guessing.

Workflow

1. Decide the mode

  • Text-to-video — prompt only. Best when there is no source image.
  • Image-to-video — pass --first-frame img.png. The still becomes the opening frame and the model adds motion. This is the right mode for animating a storyboard panel or product render.
  • First→last morph — pass both --first-frame a.png and --last-frame b.png to interpolate a transition between two stills.
  • Reference-guided — --image path:reference_image (repeatable) to steer style/composition.

If the user attached an image, default to image-to-video unless they clearly want a fresh scene.

2. Craft the prompt

Read references/prompting.md before writing a non-trivial prompt. Seedance responds well to prompts that describe the shot over time (beats like [0s-2s] … [2s-5s] …), the camera move, and what must stay fixed. For image-to-video, explicitly state which traits of the source to preserve (style, framing, colors) so the clip does not drift.

3. Run the script

Invoke it directly (the shebang runs it through uv):

${CLAUDE_PLUGIN_ROOT}/skills/generate-video/scripts/generate_video.py "PROMPT" -o OUT.mp4 [flags]

Changes

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.
