  "documentation": "# Stability AI Image\n\n该目录是独立官方协议插件源码。后端从生成的 `stability-image.yingce-plugin` 包加载，不依赖系统内置 `host:` 适配器。\n\n完整接口见 [docs/interface.md](docs/interface.md)。\n\n---\n\n# Stability AI Image 接口字段\n\n## 协议身份\n\n- 插件 ID：`stability-image`。\n- Provider ID：`stability-image`。\n- 能力：`image`。\n- 默认 Base URL：`https://api.stability.ai`。\n- 鉴权驱动：`bearer`。\n- 创建：`POST 动态路径`。\n- 生命周期：同步响应。\n\n## 配置字段\n\n| 字段 | 类型 | 必填 | 含义 |\n| --- | --- | --- | --- |\n| `apiKey` | secret | 是 | API Key |\n\n## 统一字段映射\n\n| 统一字段 | 类型 | 必填 | 上游映射 | 说明 |\n| --- | --- | --- | --- | --- |\n| `model` | string | 是 | `model` | 图片模型 ID。 |\n| `prompt` | string | 是 | `prompt` | 图片提示词。 |\n| `images` | media[] | 否 | `provider image/reference fields` | 参考图或编辑源图，role 由业务层确定。 |\n| `imageCount` | integer | 否 | `n/sample_count` | 输出数量。 |\n| `aspectRatio` | string | 否 | `size/aspect_ratio` | 比例或尺寸，语义按协议说明。 |\n| `resolution` | string | 否 | `resolution/imageSize` | 分辨率档位。 |\n| `quality` | string | 否 | `quality` | 质量档位。 |\n| `providerOptions` | object | 否 | `provider-specific fields` | 插件命名空间内的厂商扩展字段。 |\n\n## 上游请求模板逐字段清单\n\n下表由插件请求模板生成，覆盖 body、query、headers 和 multipart 文件声明中的每个字段。\n\n| 上游位置 | 值或转换表达式 |\n| --- | --- |\n| `create.method` | `\"POST\"` |\n| `create.path` | `\"dynamic\"` |\n| `create.contentType` | `\"multipart/form-data\"` |\n| `create.body.prompt` | `{\"$ref\":\"request.prompt\"}` |\n| `create.body.negative_prompt` | `{\"$omitEmpty\":{\"$ref\":\"request.providerOptions.stability-image.negative_prompt\"}}` |\n| `create.body.aspect_ratio` | `{\"$omitEmpty\":{\"$ref\":\"request.aspectRatio\"}}` |\n| `create.body.output_format` | `{\"$coalesce\":[{\"$ref\":\"request.output.format\"},{\"$ref\":\"request.providerOptions.stability-image.output_format\"},\"png\"]}` |\n| `create.body.seed` | `{\"$omitEmpty\":{\"$ref\":\"request.providerOptions.stability-image.seed\"}}` |\n| `create.body.style_preset` | `{\"$omitEmpty\":{\"$ref\":\"request.providerOptions.stability-image.style_preset\"}}` |\n| `create.body.strength` | `{\"$omitEmpty\":{\"$ref\":\"request.providerOptions.stability-image.strength\"}}` |\n| `create.body.cfg_scale` | `{\"$omitEmpty\":{\"$ref\":\"request.providerOptions.stability-image.cfg_scale\"}}` |\n| `create.body.grow_mask` | `{\"$omitEmpty\":{\"$ref\":\"request.providerOptions.stability-image.grow_mask\"}}` |\n| `create.body.creativity` | `{\"$omitEmpty\":{\"$ref\":\"request.providerOptions.stability-image.creativity\"}}` |\n| `create.headers.Accept` | `\"application/json\"` |\n| `create.files[0].name` | `\"image\"` |\n| `create.files[0].source` | `{\"$first\":{\"$filter\":{\"from\":{\"$sortByOrder\":{\"$ref\":\"request.images\"}},\"as\":\"media\",\"where\":{\"$in\":[{\"$ref\":\"media.role\"},[\"edit_source\",\"reference_image\",\"\"]]}}}}` |\n| `create.files[0].filename` | `\"image.png\"` |\n| `create.files[1].name` | `\"mask\"` |\n| `create.files[1].source` | `{\"$first\":{\"$filter\":{\"from\":{\"$sortByOrder\":{\"$ref\":\"request.images\"}},\"as\":\"media\",\"where\":{\"$in\":[{\"$ref\":\"media.role\"},[\"mask\"]]}}}}` |\n| `create.files[1].filename` | `\"mask.png\"` |\n\n## Provider 扩展键\n\n- `providerOptions.stability-image.cfg_scale`\n- `providerOptions.stability-image.creativity`\n- `providerOptions.stability-image.endpoint`\n- `providerOptions.stability-image.grow_mask`\n- `providerOptions.stability-image.negative_prompt`\n- `providerOptions.stability-image.output_format`\n- `providerOptions.stability-image.seed`\n- `providerOptions.stability-image.strength`\n- `providerOptions.stability-image.style_preset`\n\n动态模型或工作流允许使用文档声明的完整 `parameters/input/extra_body` 对象；该对象是协议本身的开放 schema，不会被宿主裁剪。\n\n## 响应映射逐字段清单\n\n| 映射位置 | 上游路径或转换表达式 |\n| --- | --- |\n| `response.status` | `{\"$if\":{\"condition\":{\"$ref\":\"response.errors\"},\"then\":\"failed\",\"else\":\"succeeded\"}}` |\n| `response.message` | `{\"$coalesce\":[{\"$ref\":\"response.errors\"},{\"$ref\":\"response.message\"}]}` |\n| `response.images` | `{\"$if\":{\"condition\":{\"$ref\":\"response.image\"},\"then\":[{\"dataUrl\":{\"$concat\":[\"data:\",{\"$coalesce\":[{\"$ref\":\"response.mime_type\"},\"image/png\"]},\";base64,\",{\"$ref\":\"response.image\"}]}}],\"else\":null}}` |\n| `response.errorPaths[0]` | `\"errors\"` |\n\n## 响应与错误\n\n插件把上游 task/status/text/media/usage 映射为统一结果。临时媒体 URL 标记为 ephemeral，由宿主立即下载持久化。HTTP 错误、业务 code 和 error object 保持失败语义，不包装成成功。\n\n## 兼容边界\n\n该包只代表上述线协议 profile；同一品牌的其他 endpoint、云区域或网关包装必须使用独立插件，不能根据模型名猜测。\n\n<!-- YINGCE_MANIFEST_CONTRACT_START -->\n## Manifest 完整接口定义\n\n以下 JSON 与插件包内实际 `manifest.json` 逐字段一致，覆盖插件身份、权限、配置、鉴权、参数、校验、创建、Agent、查询、取消、结果下载、响应和 Agent 响应映射。`documentation` 字段的值就是当前完整文档；为避免文档在自身内部无限递归，JSON 中仅用等义占位文本表示正文。\n\n```json\n{\n  \"apiVersion\": \"yingce.plugin/v2\",\n  \"id\":
