# Workflows
> Orchestrate execution with sleep and halt
## Overview
The `ctx` object provides workflow control methods that help you manage execution timing and optimize resource usage.
## Methods
### sleep()
Pause execution for a specified duration.
```typescript theme={null}
ctx.sleep(milliseconds: number): Promise
```
**Example:**
```typescript theme={null}
await ctx.sleep(1000); // Sleep for 1 second
```
### halt()
Signal to the workflow orchestrator that this column's result makes all other columns in the row pointless. This helps the system avoid wasted parallel work.
```typescript theme={null}
ctx.halt(reason?: string): void
```
`halt()` should only be used AFTER expensive operations when the result disqualifies the entire row. Don't use it for simple validation or early returns.
**Example:**
```typescript theme={null}
const analysis = await services.ai.generateObject({
prompt: `Analyze if ${companyName} is in our ICP`,
schema: z.object({ isICP: z.boolean() }),
});
if (!analysis.object.isICP) {
ctx.halt("Not in ICP");
return false;
}
```
