> **This method is not served on the public API.** `api.sylphx.com` does not route this call: its backend is not deployed behind the public API, or does not implement the call. This page documents the contract. It is kept out of the sidebar and of search engines.

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

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

## get

Gets a build cache.

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

**CLI**

```bash
sylphx build build-caches get orgs/acme/projects/shop/build_caches/build-cache
```

`GET https://api.sylphx.com/v1/orgs/acme/projects/shop/build_caches/build-cache` · scope `build:read` · effect `read` · [Request, response and examples](/docs/api/build_caches/get)

## list

Lists build caches in a project.

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

**CLI**

```bash
sylphx build build-caches list orgs/acme/projects/shop
```

`GET https://api.sylphx.com/v1/orgs/acme/projects/shop/build_caches` · scope `build:read` · effect `read` · [Request, response and examples](/docs/api/build_caches/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, filterable fields, and Ready. |
| `--order-by` | `string` | AIP-132 ordering over filterable fields. |

## update

Updates a build cache.

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

**CLI**

```bash
sylphx build build-caches update orgs/acme/projects/shop/build_caches/build-cache
```

`PATCH https://api.sylphx.com/v1/orgs/acme/projects/shop/build_caches/build-cache` · scope `build:write` · effect `write` · [Request, response and examples](/docs/api/build_caches/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.retention` | `duration` | Entries unused this long are evicted; default 7 days. |
| `--allow-missing` | `bool` | Create the Resource when it does not exist (declarative upsert). |
| `--dry-run` | `bool` | Validate and print the result without writing (validate_only). |

## delete

Deletes a build cache.

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

**CLI**

```bash
sylphx build build-caches delete orgs/acme/projects/shop/build_caches/build-cache --yes
```

`DELETE https://api.sylphx.com/v1/orgs/acme/projects/shop/build_caches/build-cache` · scope `build:write` · effect `destructive` · [Request, response and examples](/docs/api/build_caches/delete)

**Flags**

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