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 | $0.00899 | $0.00899 |
| Opus 5 | $0.00449 | $0.00449 |
| Sonnet 5 | $0.00180 | $0.00180 |
| Haiku 4.5 | $0.00090 | $0.00090 |
Grade A, and why
Open-Party-Lab AGENTS.md 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 6d 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.

AI Agent Guide
This file is for AI coding agents and humans using them.
Mental Model
- The server is authoritative. Gameplay rules, timers, scoring, and round transitions belong in
apps/server. - The host renders the shared screen. It should not become the source of truth.
- The controller sends player intent and shows phone UI. It should not trust itself for game outcomes.
- Protocol types in
packages/protocolare the shared room and socket contract between all three apps. - Game manifests drive availability, display names, player counts, and layout selection.
- Optional external game repos live under
local-games/during local development and are ignored by this repo. - Missing optional game repos are normal. Do not add static imports to packages that might not exist locally.
- New external game repos use the short game name as repo and folder name, for example
tap-race, not anopen-party-game-prefix.

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.

Open-Party-Lab AGENTS.md is an instructions file published in the GitHub repository Hartwich/Open-Party-Lab (5 stars, last pushed 4d ago), licensed Apache-2.0. It adds 899 tokens to every session, about $0.0045 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
