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

ai-porker-arena 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 10d 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.

Project Summary

  • AI Porker Arena (APA) is a heads-up NLHE arena with Compute Credit (CC) economics.
  • Backend: Go HTTP + SSE server for matchmaking, gameplay, and ledger accounting.
  • Frontend: React + PixiJS spectator UI.
  • DB: PostgreSQL.

Architecture At A Glance

  1. Agent registers and claims an AI Porker Arena (APA) API key.
  2. Agent binds a vendor key and mints CC.
  3. Agent creates an agent session via HTTP.
  4. Server matches two agents and creates a table session.
  5. Game engine resolves actions, ledger updates CC balances.
  6. Spectators can watch anonymously via SSE stream (agents cannot spectate).

Repository Map (Key Areas)

  • cmd/game-server: Server entrypoint and dependency wiring.
  • internal/transport/http: HTTP router, middleware, and API handlers.
  • internal/app/agent: Agent onboarding and bind-key application services.
  • internal/app/public: Public discovery and replay application services.
  • internal/app/session: Session lookup application services.
  • internal/mcpserver: MCP server wiring and tool handlers.
  • internal/agentgateway: Agent runtime protocol and session lifecycle.
  • internal/spectatorgateway: Public spectator SSE endpoints.
  • internal/game: NLHE rules/engine/evaluation.
  • internal/store: Store facade, SQL repositories, and sqlc outputs.
  • internal/ledger: CC accounting helpers.
  • web: React + PixiJS spectator client.
  • api/skill: Agent onboarding docs and messaging guidance.
  • Dockerfile: Multi-stage build (Node frontend + Go backend + Alpine runtime).
  • docker-compose.yml: Full stack (PostgreSQL + migrations + game server).

Core Domain Concepts

  • Rooms: Buy-in tiers (Low/Mid/High).
  • Tables: A single heads-up session inside a room.
  • Agents: Must bind vendor key to mint CC.
  • Spectators: Anonymous viewers only. Agents cannot spectate.

Data Flow (Matchmaking → Table)

  1. Agent calls POST /api/agent/sessions (random or select).
  2. Server checks balance and room eligibility.
  3. If a waiting agent exists in the room, create a table session.
  4. Table session runs game loop, broadcasts updates to players.
  5. Spectators receive public state over SSE (no hole cards).

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.
