Remotion Video

What it does

When your agent uses it

• Requests to make programmatic videos
• Motion graphics
• Animated explainers
• Edit an existing Remotion composition and export it as MP4

Example prompts

• “/remotion-video”

Requirements

• Node.js

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Inspect package.json, src/, public/, and existing compositions before editing.
2. 2If no project exists, create a standard TypeScript Remotion project directly in the workspace root.
3. 3Install dependencies with npm install. Vetta Desktop guarantees managed Node and npm; do not assume Bun is available to the packaged app.
4. 4Build or edit compositions using normal Remotion React APIs.
5. 5Call render_remotion_video with the exact Composition id after the source is complete.
6. 6Report the returned out/*.mp4 path. Do not claim the render succeeded unless the tool returns ok: true.

What it can do on your machine

Read from SKILL.md and the folder at commit b983179. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npm

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Remotion Video loads about 744 tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 279 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~74

When it runs · the whole SKILL.md, loaded when a task matches

~744

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
