What is multiplayer-p2p?

A peer-to-peer multiplayer setup using WebRTC data channels, where 2–8 players connect directly and a server only helps them find one another. WebRTC is a browser technology for direct realtime connections.

Building small co-op games, shared cursors, collaborative drawing, and other realtime features for 2–8 connected users.

It supports low-latency shared experiences without sending every message through a server or paying for per-message server processing.

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	$0.00102	$0.04704
Opus 5.5	$0.00041	$0.01882
Sonnet 5.5	$0.00020	$0.00941
Haiku 4.5	$0.00010	$0.00470

Security

Grade A, and why

multiplayer-p2p 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.

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.
