The Worlds Platform maintains an internal logging system to track world-specific events and provide an audit trail for agent actions.

​
Logs service

The LogsService manages logs within a world’s database. Defined in lib/database/world/logs/service.ts, it provides the following capabilities:
  • listByWorld(worldId, limit): Retrieves logs in descending chronological order.
  • listSince(sinceTimestamp, limit): Retrieves logs in ascending order starting from a specific timestamp.

​
Log levels

The platform utilizes standard log levels to categorize severity and intent: info, warn, error, and debug.

​
Log triggers

Specific platform events automatically trigger log entries in the world-scoped database for auditing and debugging:
