# azure-keyvault-py non-hero scenarios

These scenarios are intentionally separate from hero flows in `SKILL.md`.
They cover secondary/advanced patterns typically used after the primary end-to-end path is working.

## Async Clients

```python
from azure.identity.aio import DefaultAzureCredential
from azure.keyvault.secrets.aio import SecretClient

async def get_secret():
    async with DefaultAzureCredential() as credential:
        async with SecretClient(vault_url=vault_url, credential=credential) as client:
            secret = await client.get_secret("my-secret")
            print(f"Retrieved secret: {secret.name} (version: {secret.properties.version})")

import asyncio
asyncio.run(get_secret())
```

## Error Handling

```python
from azure.core.exceptions import ResourceNotFoundError, HttpResponseError

try:
    secret = client.get_secret("nonexistent")
except ResourceNotFoundError:
    print("Secret not found")
except HttpResponseError as e:
    if e.status_code == 403:
        print("Access denied - check RBAC permissions")
    raise
```
