Breaking the Loop: 5-Step Agent Iteration Guardrails

Architecture · updated Sun Feb 22

Guardrails to prevent autonomous agents from repeating the same actions indefinitely.

Steps

  1. Set a strict max_iterations limit (default: 5).
  2. Compare the current planned tool call against the previous three actions and trigger a path-change step if identical.
  3. If a loop is detected, require a fundamentally different approach instead of retrying the same tool.
  4. Define a hard-fail threshold that forces a stop and requests human feedback.
  5. Reset short-term tool reasoning cache while preserving the core objective.
