Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00077 | $0.02032 |
| Opus 5 | $0.00039 | $0.01016 |
| Sonnet 5 | $0.00015 | $0.00406 |
| Haiku 4.5 | $0.00008 | $0.00203 |
Grade A, and why
zihin-triggers-e-canais 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.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Triggers e canais
Contrato formal: zihin://schemas/trigger_config (granularidade de ENTIDADE — no create_trigger você envia só agent_id, name, trigger_type e trigger_config; tenant_id/ids são injetados pelo servidor). Tipos: webhook, schedule, email, db_event.
create_trigger/get_trigger/list_triggers de webhook retornam um bloco call com a URL chamável + qual header de auth enviar (ver §Como chamar). ⚠️ NÃO retornam a API Key — a key é do tenant, gerada à parte; entregue a URL + a key ao usuário.
Webhook — decisões na ordem certa
Pergunte antes de montar: qual sistema chama? em qual campo vem a mensagem? qual formato de resposta o sistema espera? precisa manter contexto por usuário?
- Extração:
query_extraction: { mode: "field", field: "message" }(oufull_body). - Formato de resposta —
response_adapter.format:raw(default, integrações genéricas) ·ebarn(array) ·slack(Block Kit) ·teams(Adaptive Card) ·twiml(Twilio/WhatsApp — aplicastrip_markdownemax_length=4096automaticamente).
- Sessão —
session_strategy:{ "mode": "derive", "fields": ["idUsuario"] }= session_id determinístico → 1 conversa contínua por usuário.{ "mode": "ephemeral" }= sessão nova a cada disparo.- ⚠️ GOTCHA REAL: os
fieldsdo derive precisam resolver viacontext_mapping— se o campo não existir no contexto, cai SILENCIOSAMENTE em sessão nova a cada mensagem (contexto perdido sem erro).
- Controle de acesso —
sender_access.mode:any(default) |members(sótenant_users, comidentity_field/match_column) |whitelist(lista explícita). Esses são os ÚNICOS valores — não invente (ex.: "public" não existe). - Execução —
execution.mode:sync(default, responde no mesmo request) |async(ack imediato + resultado viacallbackcom url/method/authsecret_ref/body_template). - Opcionais:
context_mapping(campos do body → contexto do agente, renderizados no prompt),message_buffer(debounce de mensagens rápidas via janela),split_config(divide respostas longas em chunks p/ WhatsApp/SMS).
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.

zihin-triggers-e-canais is a skill published in the GitHub repository zihin-ai/zihin-mcp (0 stars, last pushed 10d ago), licensed MIT. It adds 77 tokens to every session and 2,032 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
