Module 03 Summary

What this module established

Sequential guarantees a readable order and wastes work on tasks that should have been skipped - fix that with a guardrail or a flow, not by adding a manager. Hierarchical makes routing a model decision with an error rate that does not improve on its own, and every one of its failures burns a manager call before it burns a worker call.

Carry forward

• If the routing rule can be written down, write it. A flow applies it correctly every time for no tokens.
• The manager adds roughly half again in tokens for the same work, and produces nothing a user sees.
• Default allow_delegation to False. Leaving it True gives every agent a path to every other, which is a complete graph of possible loops.

Before moving on

Move on when you have attempted the routing rule as code, priced both processes on real volume, and set delegation deliberately rather than by default.
