Create a new lifecycle rule. A rule must include a transition (`--storage-class` with `--days` or `--date`) and/or an expiration (`--expire-days` or `--expire-date`), and may optionally be scoped via `--prefix`.

**Alias:**`c`

## Usage

```bash
tigris buckets lifecycle create <name> [flags]

t3 b lc c <name> [flags]
```

## Flags

| Name                  | Required | Default | Description                                                          |
|-----------------------|----------|---------|----------------------------------------------------------------------|
| `--prefix`, `-p`     | No       | —       | Key prefix to scope the rule to. Omit for a bucket-wide rule       |
| `--storage-class`, `-s` | No    | —       | Target storage class for the transition                             |
| `--days`, `-d`       | No       | —       | Transition objects after this many days (used with `--storage-class`)|
| `--date`             | No       | —       | Transition objects on this date, ISO-8601 (used with `--storage-class`)|
| `--expire-days`      | No       | —       | Expire (delete) objects after this many days                        |
| `--expire-date`      | No       | —       | Expire (delete) objects on this date, ISO-8601                    |
| `--disable`          | No       | —       | Create the rule in a disabled state                                 |

A rule must include at least one of: a transition (`--storage-class` plus `--days` or `--date`) or an expiration (`--expire-days` or `--expire-date`).

## Examples

```bash
# Transition all objects to STANDARD_IA after 30 days
tigris buckets lifecycle create my-bucket --storage-class STANDARD_IA --days 30

# Scope to a prefix: archive logs/ to GLACIER after 90 days
tigris buckets lifecycle create my-bucket --prefix logs/ --storage-class GLACIER --days 90

# Expire objects under tmp/ after 7 days
tigris buckets lifecycle create my-bucket --prefix tmp/ --expire-days 7

# Transition then expire: archive/ → GLACIER at 30d, delete at 365d
tigris buckets lifecycle create my-bucket --prefix archive/ \
  --storage-class GLACIER --days 30 --expire-days 365
```
