Record a fact

Record the value of a definition for a contact or a conversation, or that it has none (valueStatus: unknown or not_applicable). Only record something actually observed, and say where it came from (sourceConversationId, sourceMessageId, reason). The value follows the definition's type: text, number, boolean, a YYYY-MM-DD date or an option key. The newest assertion that was not rejected becomes the current fact; older ones stay as history. Get definitionId from list_definitions.

Scope: raiz:facts:write
Credentials: an API key, a client-credentials token or a person's access token
Effect: writes; not idempotent: check the outcome before you retry
Limits: request body up to 32 KB, response up to 1 MB
CLI: arbol raiz facts create · MCP tool: raiz_facts_create
