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

tray-cupons scanned grade A with 1 finding 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 9d ago.

The scan reads SKILL.md. This mod also ships 24 executable files (examples/cupom-atualizar.curl.sh, examples/cupom-atualizar.node.mjs, examples/cupom-consultar.curl.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

MANDATORY: Tool Calls Required Before Answering

Estas chamadas são OBRIGATÓRIAS, não opcionais. Execute-as antes de gerar qualquer código ou payload. Se você está respondendo sem ter chamado a ferramenta abaixo, pare e chame agora.

1. Buscar documentação atualizada (sempre)

node skills/tray-dev/scripts/search_docs.mjs --topic=cupons "<termo da pergunta>"
  • <TOPIC_SLUG>: ver tabela em skills/tray-dev/SKILL.md.
  • Use os trechos retornados como fonte primária; este SKILL.md é resumo denso.

2. Revisar campos (este recurso ainda NÃO tem validate.mjs)

Nota: o recurso cupons ainda não possui scripts/validate.mjs local. A chamada OBRIGATÓRIA a search_docs.mjs acima continua valendo. Como não há validador automático, você é responsável por revisar manualmente cada campo obrigatório (code, value, type) contra a doc retornada por search_docs.mjs e contra os schemas de referência em skills/cupons/schemas/ antes de retornar qualquer código. Confira em especial: chave de recurso DiscountCoupon presente no body, code sem espaços nem acentos, type em $/%, e coerência entre usage_counter_limit e usage_counter_limit_customer.

Antes de responder

Execute estas verificações antes de gerar qualquer payload ou código:

  1. Confirme o método HTTP e o endpoint correto para a operação solicitada (CRUD em /discount_coupons, consulta de relacionamento em /discount_coupons/<tipo>_relationship/:id, ou criação de vínculo em /discount_coupons/create_relationship/:id).
  2. Identifique os campos obrigatórios listados neste documento — code, value e type nunca podem faltar na criação; não omita nenhum.
  3. Verifique que access_token não aparece como literal string no código gerado — use sempre TRAY_ACCESS_TOKEN e TRAY_API_ADDRESS por variável de ambiente.
  4. Confirme que esta é a skill correta para o recurso: cupom é desconto por código no checkout; se for preço permanente por grupo, leia when_not_to_use e redirecione para tray-listas-preco-b2b.

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.
