# workflows versions dependencies create

## Synopsis

```shell
omics workbench workflows versions dependencies create
  --workflow=WORKFLOW_ID
  --version=VERSION_ID
  --name=DEPENDENCY_NAME
  --dependency=DEPENDENCY_SPEC [--dependency=DEPENDENCY_SPEC ...]
  [--global]
  [--namespace=NAMESPACE]
```

## Description

Create a new workflow dependency that establishes prerequisites for a workflow version. Dependencies ensure that specified workflows are executed before the current workflow runs. You can specify multiple dependencies and use automatic version resolution.

Dependency specifications can be provided in two formats:

* `workflow-id/version-id` - Specifies an explicit version
* `workflow-id` - Automatically resolves to the latest version

## Examples

Create a simple workflow dependency:

```shell
omics workbench workflows versions dependencies create \
  --workflow 40c67272-3553-4bb1-8662-81c81acff347 \
  --version latest \
  --name "Data preprocessing" \
  --dependency "5633fe10-b66a-4a20-8258-9963e4cac6fa/v1.0"
```

Create a dependency with automatic version resolution:

```shell
omics workbench workflows versions dependencies create \
  --workflow 40c67272-3553-4bb1-8662-81c81acff347 \
  --version v2.0 \
  --name "Analysis pipeline" \
  --dependency "preprocessing-workflow"
```

Create a dependency with multiple prerequisites:

```shell
omics workbench workflows versions dependencies create \
  --workflow 40c67272-3553-4bb1-8662-81c81acff347 \
  --version latest \
  --name "Multi-step analysis" \
  --dependency "data-cleaning/v1.2" \
  --dependency "quality-control/v2.1" \
  --dependency "normalization"
```

Create a global dependency (admin only):

```shell
omics workbench workflows versions dependencies create \
  --workflow 40c67272-3553-4bb1-8662-81c81acff347 \
  --version latest \
  --name "System dependency" \
  --dependency "system-init/v1.0" \
  --global
```

## Flags

### `--workflow`=`WORKFLOW_ID`

**Required**. Specify the UUID of the workflow for which you want to create a dependency.

### `--version`=`VERSION_ID`

**Required**. Specify the version ID of the workflow for which you want to create a dependency.

### `--name`=`DEPENDENCY_NAME`

**Required**. A human-readable name for the dependency that describes its purpose.

### `--dependency`=`DEPENDENCY_SPEC`

**Required**. Specify a dependency in the format `workflow-id/version-id` or `workflow-id`. When only the workflow ID is provided, the system automatically resolves to the latest available version. This flag can be specified multiple times to create dependencies on multiple workflows.

### `--global`

Create a global dependency that applies across all namespaces. This flag requires administrator privileges and adds the `X-Admin-Only-Action` header to the request.

### `--namespace`=`NAMESPACE`

An optional flag to define the namespace to connect to. By default, the namespace is extracted from the user's credentials.
