Circuit Breaker (Agent)

Circuit breakers trip on signals such as repeated errors, anomalous spending, abnormal data access, or detected goal drift. Unlike a global kill switch, they target a specific failure mode and can reset automatically when conditions improve.

Agent circuit breakers can trip on:

• Error rate: Bursts of tool failures or model errors above a threshold.
• Cost or volume: Excess spend, API calls, or token consumption.
• Sensitive access: Repeated reads or writes against classified data.
• Behavioral drift: Deviations from established intent or behavioral baselines.
• External signals: Incident tickets, regulatory alerts, or threat intel feeds.

Well-designed circuit breakers also self-heal once the underlying condition clears, which is what separates them from blunt kill switches. The discipline of choosing the right granularity (per-tool, per-agent, per-workflow) is where most operational maturity lies.

Programs that operate circuit breakers well also instrument them with rich telemetry, so each trip becomes a learning signal rather than a black box outage.

How PointGuard AI Helps

PointGuard AI Runtime Guardrails ship configurable circuit breakers tied to behavior, cost, and sensitivity signals, with policy and evidence flowing back to AI Governance. The combination keeps consequential agent failures bounded and recoverable rather than letting them cascade into outages.
