Remotion Best Practices

What it does

When your agent uses it

• Asked to create
• Edit videos programmatically

Example prompts

• “/remotion-best-practices”

Requirements

• Node.js

Workflow steps

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

1. 1Read rules: Load the relevant rule files below based on the task
2. 2Scaffold (do NOT use npx create-video — it requires interactive prompts)
3. 3Create project files
4. 4Build: Write React components following Remotion patterns from the rules.
5. 5Render (ALWAYS do this — never stop before rendering)

What it can do on your machine

Read from SKILL.md and the folder at commit 7bfc65d. 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:

  • npx
  • npm

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

• Network

  No URLs in SKILL.md. Its commands use npx and 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 Best Practices loads about 2.3k tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 862 words of instructions outside code blocks.

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

~36

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

~2.3k

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

• NoteMentions a .env fileSKILL.md:177

  m env/secret store, not hard-coded, and `.env` files are not committed

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 862 words (~2,250 tokens).
