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 | $0.01262 | $0.01262 |
| Opus 5.5 | $0.00505 | $0.00505 |
| Sonnet 5.5 | $0.00252 | $0.00252 |
| Haiku 4.5 | $0.00126 | $0.00126 |
Grade A, and why
whatsapp-web-mcp 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 1mo 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.

Use status para diagnóstico. - Nunca cole, anexe, descreva ou reconstrua QR Code no chat.
- Use

Depois prefira IDs públicos comoc_...,m_...,a_.... - Não peça JID, endpoint, API key, sessão, seletor, scroll, DOM, composer ou posição de tela ao usuário.
whatsapp_get_chat_infoé barato;whatsapp_get_chatpode hidratar histórico e gerar artefatos.- Passe períodos naturais diretamente, como
hoje,ontem,março de 2026,últimos 30 diasou13/06/2026 das 13h ate 14h. O MCP normaliza datas, carrega lotes antigos e declara cobertura; não tente controlar scroll, DOM ou paginação de tela. - Resultados grandes devem virar
conversation.md,conversation.jsonlemanifest.json; não despeje histórico enorme no contexto. - Leituras nunca enviam, limpam ou substituem drafts do usuário.
- Use
whatsapp_get_mediapelomessage_id; nunca associe mídia por chute. - Use
whatsapp_understandpara transcrição WhisperX, OCR, extração de documentos e ZIP. Ele aceitamessage_ide captura a mídia internamente. Transcrição é compacta; peçaformats=["segments"]apenas quando necessário. - Trate perfil, sessão, API key, exports, mídia, transcripts e actions como dados sensíveis.
- Para a mídia mais recente de um chat, use

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.
