# Schedules

Create recurring tasks that run on a cron schedule inside a box. You can schedule shell commands or agent prompts. Available on both `box.schedule` and `ephemeralBox.schedule`.

***

## API

### Schedule a shell command

Run a shell command on a cron schedule.

```typescript theme={"system"}
const schedule = await box.schedule.exec({
  cron: "* * * * *",
  command: ["bash", "-c", "date >> /workspace/home/cron.log && echo scheduled-ok"],
  webhookUrl: "https://example.com/hook",          // optional
  webhookHeaders: { Authorization: "Bearer ..." }, // optional
  folder: "/workspace/home",                       // optional, defaults to box.cwd
})

console.log(schedule.id)
```

| Parameter        | Required | Description                                                                  |
| ---------------- | -------- | ---------------------------------------------------------------------------- |
| `cron`           | Yes      | 5-field cron expression (UTC)                                                |
| `command`        | Yes      | `string[]` — the command to run                                              |
| `webhookUrl`     | No       | URL to notify when the scheduled run completes                               |
| `webhookHeaders` | No       | Headers to include in the webhook request                                    |
| `folder`         | No       | Working directory. Defaults to `box.cwd`; relative paths resolved against it |

### Schedule an agent prompt

Run an agent prompt on a cron schedule. Requires an agent to be configured on the box.

```typescript theme={"system"}
const schedule = await box.schedule.agent({
  cron: "0 9 * * *",
  prompt: "Run the test suite and fix any failures",
  model: "anthropic/claude-sonnet-4-6",          // optional, overrides box's model
  timeout: 300_000,                     // optional, kill the run after 5 minutes
  options: { maxBudgetUsd: 1.0 },      // optional, provider-specific agent options
})

console.log(schedule.id)
```

| Parameter        | Required | Description                                                                                 |
| ---------------- | -------- | ------------------------------------------------------------------------------------------- |
| `cron`           | Yes      | 5-field cron expression (UTC)                                                               |
| `prompt`         | Yes      | The prompt to send to the agent                                                             |
| `folder`         | No       | Working directory. Defaults to `box.cwd`; relative paths resolved against it                |
| `model`          | No       | Override the box's default model for this schedule                                          |
| `options`        | No       | Provider-specific agent options (e.g. `maxBudgetUsd`, `effort`, `systemPrompt`, `maxTurns`) |
| `timeout`        | No       | Timeout in milliseconds — kills the run if exceeded                                         |
| `webhookUrl`     | No       | URL to notify when the scheduled run completes                                              |

### List schedules

Retrieve all non-deleted schedules for the current box.

```typescript theme={"system"}
const schedules = await box.schedule.list()

for (const s of schedules) {
  console.log(s.id, s.type, s.cron, s.status)
}
```

***

### Get a schedule

Retrieve a single schedule by ID.

```typescript theme={"system"}
const schedule = await box.schedule.get("schedule_abc123")

console.log(schedule.type)   // "exec" | "prompt"
console.log(schedule.status) // "active" | "paused" | "deleted"
console.log(schedule.cron)
```

***

### Pause a schedule

Pause an active schedule so it stops running.

```typescript theme={"system"}
await box.schedule.pause("schedule_abc123")
```

***

### Resume a schedule

Resume a paused schedule.

```typescript theme={"system"}
await box.schedule.resume("schedule_abc123")
```

***

### Delete a schedule

Remove a schedule so it no longer runs.

```typescript theme={"system"}
await box.schedule.delete("schedule_abc123")
```

***

## Schedule response

Most schedule methods return a `Schedule` object:

```typescript theme={"system"}
interface Schedule {
  id: string
  box_id: string
  type: "exec" | "prompt"
  cron: string
  command?: string[]         // present when type is "exec"
  prompt?: string            // present when type is "prompt"
  folder?: string
  model?: string
  agent_options?: Record<string, unknown>
  timeout?: number
  status: "active" | "paused" | "deleted"
  webhook_url?: string
  webhook_headers?: Record<string, string>
  last_run_at?: number
  last_run_status?: "completed" | "failed" | "skipped"
  last_run_id?: string
  total_runs: number
  total_failures: number
  created_at: number
  updated_at: number
}
```

***

## Cron syntax

Schedules use standard 5-field cron expressions (UTC):

```
┌───────────── minute (0-59)
│ ┌───────────── hour (0-23)
│ │ ┌───────────── day of month (1-31)
│ │ │ ┌───────────── month (1-12)
│ │ │ │ ┌───────────── day of week (0-6, Sun=0)
│ │ │ │ │
* * * * *
```

| Expression    | Description         |
| ------------- | ------------------- |
| `* * * * *`   | Every minute        |
| `0 * * * *`   | Every hour          |
| `0 9 * * *`   | Daily at 9:00 AM    |
| `0 9 * * 1-5` | Weekdays at 9:00 AM |
| `*/5 * * * *` | Every 5 minutes     |

## Examples

### Periodic health check

Schedule a command that checks whether your service is healthy.

```typescript theme={"system"}
import { Agent, Box } from "@upstash/box"

const box = await Box.create({ runtime: "node" })

await box.schedule.exec({
  cron: "*/5 * * * *",
  command: ["bash", "-c", "curl -sf http://localhost:3000/health || echo UNHEALTHY >> /workspace/home/health.log"],
})
```

### Daily code review agent

Schedule an agent to review recent changes every morning.

```typescript theme={"system"}
import { Agent, Box } from "@upstash/box"

const box = await Box.create({
  runtime: "node",
  agent: {
    harness: Agent.ClaudeCode,
    model: "anthropic/claude-sonnet-4-5",
    apiKey: process.env.ANTHROPIC_API_KEY,
  },
  git: { token: process.env.GITHUB_TOKEN },
})

await box.git.clone({ repo: "github.com/your-org/your-repo" })

await box.schedule.agent({
  cron: "0 9 * * 1-5",
  prompt: "Pull latest changes, review the last 24h of commits, and open issues for any bugs or style violations",
  timeout: 600_000,
  options: { maxBudgetUsd: 2.0, effort: "high" },
})
```

### Manage schedules

List active schedules, pause, resume, and clean up ones you no longer need.

```typescript theme={"system"}
const schedules = await box.schedule.list()

for (const s of schedules) {
  console.log(`${s.id} — ${s.type} — ${s.cron} — ${s.status}`)
}

// Pause a schedule
await box.schedule.pause(schedules[0].id)

// Resume it later
await box.schedule.resume(schedules[0].id)

// Remove a specific schedule
await box.schedule.delete(schedules[0].id)
```
