# Update skills

Partially updates skills in the current workspace. Fields not provided retain their original values; instead of just updating the label, the update creates a new skill version and sets it as the current version.

```text
PATCH https://moi.matrixorigin.cn/newmoi/workspaces/{workspace_id}/skills/{skill_id}
```

## Before you call

First [Query skill details](get-skill.md) confirm the skill to be updated. Prepare the personal access token, target workspace ID, and skill ID that have access to the target workspace.

The example below uses:

- `$AI_STUDIO_API_KEY`: The actual personal access token, passed through the `X-API-Key` Header.
- `$WORKSPACE_ID`: Target workspace ID, passed through `X-Workspace-ID` Header.
- `$SKILL_ID`: Skill ID to be updated.

## Request example

```bash
curl -X PATCH "https://moi.matrixorigin.cn/newmoi/workspaces/$WORKSPACE_ID/skills/$SKILL_ID" \
  -H "X-API-Key: $AI_STUDIO_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID" \
  -H 'Content-Type: application/json' \
  -d '{
    "description": "更新后的说明",
    "change_summary": "补充输出约定"
  }'
```

## Path parameters

| Parameters | Type | Is it required | Description |
| --- | --- | --- | --- |
| `workspace_id` | string | Yes | The current workspace ID. |
| `skill_id` | string | Yes | The skill ID to update. |

## Query parameters

| Parameters | Type | Is it required | Description |
| --- | --- | --- | --- |
| `skill_workspace_id` | string | No | The workspace to which the skill belongs; can only be the current workspace or `system`. System skills are read-only and updates will be rejected. |

## Request body

The fields in the request body are optional; fields not provided retain their original values.

| Field | Type | Is it required | Description |
| --- | --- | --- | --- |
| `name` | string | No | Basic definition of skill. The status can be `draft`, `active`, `disabled`, or `archived`. |
| `description` | string | No | Basic definition of skill. The status can be `draft`, `active`, `disabled`, or `archived`. |
| `status` | string | No | Basic definition of skill. The status can be `draft`, `active`, `disabled`, or `archived`. |
| `source_type` | string | No | Basic definition of skill. The status can be `draft`, `active`, `disabled`, or `archived`. |
| `source_ref` | string | No | Basic definition of skill. The status can be `draft`, `active`, `disabled`, or `archived`. |
| `category` | string | No | Classification and display information. Providing `tags` replaces the existing tag; merely updating the tag does not create a new version. |
| `icon_ref` | string | No | Classification and display information. Providing `tags` replaces the existing tag; merely updating the tag does not create a new version. |
| `tags` | string[] | No | Classification and display information. Providing `tags` replaces the existing tag; merely updating the tag does not create a new version. |
| `phase` | string | No | Classification and display information. Providing `tags` replaces the existing tag; merely updating the tag does not create a new version. |
| `pipeline_ref` | string | No | Classification and display information. Providing `tags` replaces the existing tag; merely updating the tag does not create a new version. |
| `routing_summary` | object | No | Route summary, directives, and dependency requirements. |
| `instruction` | object | No | Route summary, directives, and dependency requirements. |
| `requirements` | object | No | Route summary, directives, and dependency requirements. |
| `parameters_schema` | object | No | Input Schema and output convention. |
| `output_contract` | object | No | Input Schema and output convention. |
| `market_metadata` | object | No | Market metadata, tags, annotations, and extended metadata. |
| `labels` | object | No | Market metadata, tags, annotations, and extended metadata. |
| `annotations` | object | No | Market metadata, tags, annotations, and extended metadata. |
| `metadata` | object | No | Market metadata, tags, annotations, and extended metadata. |
| `change_summary` | string | No | Change description for the new version. |

`[]` after a type denotes an array. `[]` in a field path denotes each item in an array.


The updated skill must still retain the instruction body or route summary and satisfy the validation rules for skill dependency references.
