# Function: createCrashPolicy()

```ts
function createCrashPolicy(options?: CrashPolicyOptions): CrashPolicy;
```

Defined in: [src/batteries/isolation/crash\_policy.ts:58](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/isolation/crash_policy.ts#L58)

Build a sliding-window crash-escalation policy: the first `maxCrashes - 1` crashes inside `windowMs`
each return `'respawn'`; the `maxCrashes`-th (and every crash after it, while still inside the
window) returns `'giveUp'`. Two crashes spaced further apart than `windowMs` are each treated as a
fresh, first-in-window crash — an occasional isolated crash over a long-running session never
escalates.
