The `knowledge_schemas` commands of Sylphx Knowledge, as the CLI spells them: the same
calls as [the `knowledge_schemas` API page](/docs/api/knowledge_schemas), typed for the
shell. [Install, sign in and the grammar](/docs/cli) are on the CLI index.

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

## get

Gets a knowledge schema.

**`NAME`** — the resource's name; a bare id is enough below the linked
project.

**CLI**

```bash
sylphx knowledge knowledge-schemas get orgs/acme/projects/shop/envs/production/knowledge_schemas/knowledge-schema
```

`GET https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/knowledge_schemas/knowledge-schema` · scope `knowledge:read` · effect `read` · [Request, response and examples](/docs/api/knowledge_schemas/get)

## list

Lists knowledge schemas.

**`PARENT`** — optional: the CLI fills it from the linked project or the
key's scope when it is left out.

**CLI**

```bash
sylphx knowledge knowledge-schemas list orgs/acme/projects/shop/envs/production
```

`GET https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/knowledge_schemas` · scope `knowledge:read` · effect `read` · [Request, response and examples](/docs/api/knowledge_schemas/list)

**Flags**

| Flag | Type | What it does |
| --- | --- | --- |
| `--page-size` | `int` | At most this many; default 50, clamped to 1000. |
| `--page-token` | `string` | `next_page_token` of the previous page. |
| `--filter` | `string` | AIP-160 filter over labels and filterable fields. |
| `--order-by` | `string` | AIP-132 ordering over filterable fields. |

## create

Creates a knowledge schema.

**`ID`** — The id segment of the new Resource's name; the server assigns one when omitted.

**CLI**

```bash
sylphx knowledge knowledge-schemas create --parent orgs/acme/projects/shop/envs/production
```

`POST https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/knowledge_schemas` · scope `knowledge:write` · effect `write` · [Request, response and examples](/docs/api/knowledge_schemas/create)

**Flags**

| Flag | Type | What it does |
| --- | --- | --- |
| `--parent` | `string` | The parent to create in; defaults to the linked project or the key's scope. |
| `--meta.labels` | `key=value` | Caller-writable, indexed labels (AIP-122 label rules). Repeat the flag for each value. |
| `--meta.annotations` | `key=value` | Caller-writable, unindexed annotations. Repeat the flag for each value. |
| `--meta.display-name` | `string` | Caller-writable human-readable name. |
| `--spec.entity-types` | `json` | The entity types; at most 200. Repeat the flag for each value. |
| `--spec.relation-types` | `json` | The relation types; at most 500. Repeat the flag for each value. |
| `--dry-run` | `bool` | Validate and print the result without writing (validate_only). |

## update

Updates a knowledge schema. An accepted update publishes a new revision; a change that would invalidate existing records is refused with `INVALID_FIELD`.

**`NAME`** — the resource's name; a bare id is enough below the linked
project.

**CLI**

```bash
sylphx knowledge knowledge-schemas update orgs/acme/projects/shop/envs/production/knowledge_schemas/knowledge-schema
```

`PATCH https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/knowledge_schemas/knowledge-schema` · scope `knowledge:write` · effect `write` · [Request, response and examples](/docs/api/knowledge_schemas/update)

**Flags**

| Flag | Type | What it does |
| --- | --- | --- |
| `--meta.labels` | `key=value` | Caller-writable, indexed labels (AIP-122 label rules). Repeat the flag for each value. |
| `--meta.annotations` | `key=value` | Caller-writable, unindexed annotations. Repeat the flag for each value. |
| `--meta.display-name` | `string` | Caller-writable human-readable name. |
| `--spec.entity-types` | `json` | The entity types; at most 200. Repeat the flag for each value. |
| `--spec.relation-types` | `json` | The relation types; at most 500. Repeat the flag for each value. |
| `--allow-missing` | `bool` | Create the knowledge schema when it does not exist (declarative upsert). |
| `--dry-run` | `bool` | Validate and print the result without writing (validate_only). |

## delete

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

**`NAME`** — the resource's name; a bare id is enough below the linked
project.

**CLI**

```bash
sylphx knowledge knowledge-schemas delete orgs/acme/projects/shop/envs/production/knowledge_schemas/knowledge-schema --yes
```

`DELETE https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/knowledge_schemas/knowledge-schema` · scope `knowledge:write` · effect `destructive` · [Request, response and examples](/docs/api/knowledge_schemas/delete)

**Flags**

| Flag | Type | What it does |
| --- | --- | --- |
| `--etag` | `string` | Delete only if the current etag matches. |
| `--allow-missing` | `bool` | Succeed when the knowledge schema does not exist. |
| `--dry-run` | `bool` | Validate and print the result without writing (validate_only). |
| `--yes` | `bool` | Do not ask before this destructive call. |
