# aether warm-slot

Manage warm slots — pre-warmed capacity that lets a project's workspace resume faster. The number of slots available is set by your [billing tier](/concepts/billing-and-credits).

**Alias:** `warm-slots`

## Usage

```bash theme={null}
aether warm-slot <subcommand> [flags]
```

## Subcommands

| Subcommand          | Description                           |
| ------------------- | ------------------------------------- |
| `list`              | List warm slots and their assignments |
| `assign`            | Assign a project to a slot index      |
| `release <slot-id>` | Release a slot                        |

## List

```bash theme={null}
aether warm-slot list
```

Prints your tier, how many slots are allocated out of the maximum, and a row per slot showing its index, ID, assigned project, status, snapshot, last sync, and last resume.

## Assign

```bash theme={null}
aether warm-slot assign --slot 0 --project a1b2c3d4
```

| Flag        | Description                  |
| ----------- | ---------------------------- |
| `--slot`    | Slot index (zero or greater) |
| `--project` | Project ID or unique prefix  |

## Release

aether warm-slot release <slot-id>
```

Pass the slot ID from `aether warm-slot list`.
