Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00063 | $0.01965 |
| Opus 5 | $0.00032 | $0.00983 |
| Sonnet 5 | $0.00013 | $0.00393 |
| Haiku 4.5 | $0.00006 | $0.00197 |
Grade A, and why
tray-variacoes 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.
How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 as duas ferramentas abaixo, pare e chame agora.
1. Buscar documentação atualizada (sempre)
node skills/tray-dev/scripts/search_docs.mjs --topic=variacoes "<termo da pergunta>"
<TOPIC_SLUG>: ver tabela emskills/tray-dev/SKILL.md.- Use os trechos retornados como fonte primária; este SKILL.md é resumo.
2. Validar payload localmente (antes de retornar código)
node skills/variacoes/scripts/validate.mjs --schema=<SCHEMA_NAME> '<payload_json>'
- Schemas disponíveis:
variacao.create,variacao.update. Use--list-schemaspara confirmar. - Exit codes:
0válido ·1inválido ·2erro de uso. - Para output programático:
--json. - Corrija todos os erros antes de retornar o código (até 3 tentativas).
Antes de responder
Execute estas verificações antes de gerar qualquer payload ou código:
- Confirme o método HTTP e endpoint correto para a operação solicitada.
- Identifique os campos obrigatórios listados neste documento — não omita nenhum.
- Verifique que
access_tokennão aparece como literal string no código gerado. - Confirme que esta é a skill correta para o recurso (leia

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.
