Although this is technically possible(once the bug gets fixed), what sense does it make if agents keep forever turning in circle ?

Hi @wassfila,

You’re right that an endless loop is pointless, but short, controlled cycles can be useful. Anthropic’s recent post on “Building Effective Agents” describes evaluator-optimizer (or “self-critique”) patterns where two agents deliberately hand a task back and forth until a shared stopping condition—accuracy threshold, max-iterations, etc.—is met. That requires:

1. A recursion-safe graph walk — I’ll patch get_all_nodes/edges to track a visited set so visualisation never overflows, even with cycles.

2. Conditional hand-offs — exposing a max_handoffs/“should return” hook so an agent can decide at runtime whether to hand off again or return like a tool call.

With those guards the framework supports both simple chains and the more autonomous, self-refining loops the blog highlights—without risking infinite spins.
