Runaway Loop (AI)

Runaway loops emerge from feedback in agent planning when retry, replanning, or recovery logic interacts with state in unsafe ways. Speed is the key risk multiplier: by the time a human notices, the agent may have executed thousands of harmful operations.

Common runaway loop patterns include:

• Retry storms: Repeated retries that escalate transient errors into outages or costs.
• Cascade recovery: Recovery actions that themselves trigger further failures.
• Recursive planning: Plans that endlessly generate sub-plans without convergence.
• Feedback amplification: Agent output that feeds back into its own input loop.
• Cost spirals: Unbounded use of expensive tools, APIs, or compute.

Detection benefits from monitoring derivatives such as cost-per-minute, tool-call rate, and approval-bypass frequency rather than only absolute thresholds. Catching a runaway loop early often comes down to seeing the slope of change before it crosses a hard limit.

Programs that mature fastest treat runaway loops as a class to test for in red team exercises, so the failure modes are well understood before agents reach production.

How PointGuard AI Helps

PointGuard AI Runtime Guardrails enforce rate, retry, and resource limits, and Agent Governance Mesh circuit breakers stop the workflow when loop signals exceed defined thresholds. Together they make agent autonomy a controllable property rather than a source of recurring blast-radius events.
