Flue Zero to Expert, Part 7: Operate Like an Expert

Operate Flue with structured observation, repeatable evals, and schedules that match the work lifetime.

Protect Flue routes with Hono, build the Node target, manage runtime secrets, and choose safe sandbox boundaries.

Persist Flue state with SQLite or Postgres, understand recovery limits, and make external effects idempotent.

Compose continuing agents with instructions, skills, typed subagents, and the narrowest suitable sandbox.

Give a Flue agent one narrow capability while trusted code keeps credentials, authorization, and destinations.
