Remotion Best Practices

Best practices for Remotion - Video creation in React

Security Scan

This is an instruction-only, documentation-style skill with Remotion best-practices and example React/TSX snippets; its files and instructions are coherent with the stated purpose and it does not request secrets or install arbitrary code.

Purpose & Capability

The name/description (Remotion best practices) matches the content: many markdown rules and example TSX components covering Remotion, Three.js, Mediabunny, fonts, captions, etc. Required env vars/binaries/config paths are none — consistent for a documentation skill. Example mentions of packages (e.g., @remotion/three, @remotion/media, mediabunny) are expected for Remotion guidance.

Instruction Scope

SKILL.md simply points to the rule files and instructs the agent to use the rules when dealing with Remotion code — appropriate for a guidance skill. The rule files include code examples that call fetch() and reference remote URLs (e.g., remotion.media, api.example.com) and Mediabunny APIs; these are example usage patterns, not instructions for the skill agent to exfiltrate data. Note: some examples include nonstandard/odd syntax (e.g., 'using input = new Input', 'using videoSample of ...') which appears to be pseudo/resource-management notation rather than executable JS/TS and should be reviewed before copy-paste into real projects.

Install Mechanism

No install spec — instruction-only skill. This minimizes installation risk; the files are plain markdown and example code. The skill does not download or extract remote archives or create binaries.

Credentials

The skill declares no required environment variables, credentials, or config paths. The content references installing typical Remotion/npm packages, but does not request unrelated secrets or credentials.

Persistence & Privilege

always:false and no special privileges requested. The skill does not modify other skills or system settings; autonomous model invocation is allowed (default) but not combined with other concerning behaviors.

Assessment

This skill is documentation and example code for Remotion and appears coherent with its stated purpose. Before using the code: 1) review and test the TSX examples (some snippets use nonstandard 'using' notation or pseudo-code that may need edits), 2) be aware examples show network fetches and remote URLs — only fetch from trusted endpoints, and sanitize any user-supplied URLs, and 3) when you install the npm packages the examples reference, prefer official package names on the registry and inspect package versions. No credentials or system changes are required by the skill itself, but always review example code before running it in production.

When to use

Use this skills whenever you are dealing with Remotion code to obtain the domain-specific knowledge.
