+### Prompt Caching
+
+SmartAgent enables prompt-cache defaults by default:
+
+- Anthropic-compatible models get cache breakpoints on the first two system messages and the two most recent non-system messages.
+- OpenAI models get `store: false` by default and, when `sessionId` is provided, `promptCacheKey: sessionId` with `promptCacheRetention: 'in_memory'`.
+- Longer retention is opt-in. Use `cache: { retention: '24h' }` for OpenAI or `cache: { retention: '1h' }` for Anthropic.
+- Set `cache: false` to disable these defaults for a run.
+
+```typescript
+const result = await runAgent({
+  model,
+  sessionId: 'stable-session-id',
+  prompt: 'Continue the task.',
+  tools,
+});
+
+const noCache = await runAgent({
+  model,
+  prompt: 'One-off request.',
+  cache: false,
+});
+```
+
 ### Completion Validation

 Use `validateCompletion` when a workflow must not finish unless a required side-effect happened. Return `void` to accept the run, or return a string to append that string as a new user message and continue. If retries are exhausted, `runAgent()` throws.
