Deletes a session and its events. A session whose turn is running is refused with `INVALID_STATE` unless `force` is set, which interrupts it first.

**Not available yet.** Sylphx Agents is declared in the registry but no backend serves it: every call answers `501` with the problem code `UNIMPLEMENTED`.

- **Path** `DELETE https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/agent_sessions/agent-session`
- **Scope** `agents:sessions`
- **Effect** `destructive` — a successful call removes data; the CLI asks before it runs.
- **Collection** [agent_sessions](/docs/api/agent_sessions)
- **Query** `etag`, `allow_missing`, `validate_only`, `force`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | The name of the session to delete. Required. |
| `etag` | `string` | Delete only if the current etag matches. |
| `allow_missing` | `bool` | Succeed when the session does not exist. |
| `validate_only` | `bool` | Validate without deleting anything. |
| `force` | `bool` | Interrupt a running turn and delete; without it, a running session is refused with `INVALID_STATE`. |

## Response

The call answers with an empty object.

## Errors

- [`UNAUTHENTICATED`](/docs/api/errors/UNAUTHENTICATED) — No valid key or token was presented.
- [`PERMISSION_DENIED`](/docs/api/errors/PERMISSION_DENIED) — The key lacks the method's permission.
- [`RESOURCE_NOT_FOUND`](/docs/api/errors/RESOURCE_NOT_FOUND) — The named Resource does not exist or is not visible.
- [`INVALID_STATE`](/docs/api/errors/INVALID_STATE) — The Resource is in a state that forbids the call.
- [`ETAG_MISMATCH`](/docs/api/errors/ETAG_MISMATCH) — The etag sent does not match the Resource's current etag.
- [`IDEMPOTENCY_KEY_REUSED`](/docs/api/errors/IDEMPOTENCY_KEY_REUSED) — An Idempotency-Key was reused with another body.
- [`IDEMPOTENCY_IN_PROGRESS`](/docs/api/errors/IDEMPOTENCY_IN_PROGRESS) — The first call with this Idempotency-Key is still running.

Every error arrives in the body [Errors](/docs/platform/errors) describes.
