What is remotion-player-app?

A React-based preview player for Remotion compositions, which are programmatic video scenes built with React.

Use it to add play and pause, timeline scrubbing, variant selection, aspect-ratio previews, and editable input properties to a React, Vite, Next.js, or product interface.

It lets users inspect and personalize a composition in a web app without mixing browser preview code with server-side rendering code.

Per session 32 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00032	$0.00155
Opus 5.5	$0.00013	$0.00062
Sonnet 5.5	$0.00006	$0.00031
Haiku 4.5	$0.00003	$0.00015

Security

Grade A, and why

remotion-player-app 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 2mo 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.
