composition-runtime-router

composition-runtime-router is a skill for Claude Code, Codex from clash-art/clash. It costs 50 tokens per session (342 once invoked), scanned A, original, no licence file.

A routing guide for putting React motion compositions through Clash's supported delivery path. It explains how TypeScript React animation code enters Canvas, stays live in Timeline, is previewed, and produces final media.

In plain words
What is it for?
Use it when deciding how a TSX animation should be delivered to Canvas, edited in Timeline, previewed, or rendered as final media.
Why use it?
It helps avoid confusion about where animation code should run and how it moves from authoring to output. It also clarifies that authored composition code uses Remotion.

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

composition-runtime-router 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 4d 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.

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.
