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

ot-protocols 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 8d 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.

Estado de rails (no lo re-litigues)

Rail Estado Nota
MCP ✅ v1, rail principal app/api/[transport]/route.ts con mcp-handler; demo-able con Claude hoy
Stripe hosted ✅ v1 capture mode hosted
ACP Feed publicado + conformance contra mock oficial Compra real vía ChatGPT FUERA de scope (allowlist OpenAI). /complete requiere inline_spt — fase posterior
x402 Stretch testnet Base Sepolia, facilitador CDP gratis
AP2 Overlay de autorización, no rail Usuario firma mandate con clave hardware-backed; OpenTicket genera Cart Mandate y verifica, no firma
MPP Stub tras flag redundante con x402

Trust boundary (PRD §7 — crítico)

TODO input de agente pasa por los schemas Zod de core/adapter/rails/schemas.ts. Nunca ejecutar contenido de agentes como instrucciones. Rate-limit por API key. spend_limit autodeclarado NO es control de seguridad hasta que AP2 entre — documéntalo así.

MCP tools contract (PRD US-003)

buy_ticket respeta límite de gasto y devuelve confirmación + .ics. set_reminder para el flujo agéntico. Transport JSON-RPC 2.0. Errores estructurados: sold_out, mandate_exceeded — el agente comprador decide con eso.

Changes

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.
