Deletes a knowledge schema. A schema a space still accepts is refused with `RESOURCE_IN_USE`.

**Not available yet.** Sylphx Knowledge 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/knowledge_schemas/knowledge-schema`
- **Scope** `knowledge:write`
- **Effect** `destructive` — a successful call removes data; the CLI asks before it runs.
- **Collection** [knowledge_schemas](/docs/api/knowledge_schemas)
- **Query** `etag`, `allow_missing`, `validate_only`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | The name of the knowledge schema to delete. Required. |
| `etag` | `string` | Delete only if the current etag matches. |
| `allow_missing` | `bool` | Succeed when the knowledge schema does not exist. |
| `validate_only` | `bool` | Validate without deleting anything. |

## 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.
- [`RESOURCE_IN_USE`](/docs/api/errors/RESOURCE_IN_USE) — The Resource is attached to or held by another Resource, for example a volume attached to a running lease.
- [`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.
