响应映射逐字段清单
| 映射位置 | 上游路径或转换表达式 |
|---|---|
response.status |
"succeeded" |
response.images |
{"$map":{"from":{"$ref":"response.data"},"as":"item","in":{"url":{"$omitEmpty":{"$ref":"item.url"}},"dataUrl":{"$if":{"condition":{"$ref":"item.b64_json"},"then":{"$concat":["data:image/png;base64,",{"$ref":"item.b64_json"}]},"else":null}}}}} |

"error.message" |
响应与错误
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。
兼容边界
有参考图时改走 /v1/images/edits；resolution 只接受 1k/2k；像素尺寸会换算为 aspect_ratio。
Manifest 完整接口定义
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。
