+# Atlas Cloud Chat 接口字段
+
+## 协议身份
+
+- 插件 ID：`atlascloud-chat`。
+- Provider ID：`atlascloud-chat`。
+- 能力：`text`。
+- 默认 Base URL：`https://api.atlascloud.ai`。
+- 鉴权驱动：`bearer`。
+- 创建：`POST /v1/chat/completions`。
+- Agent：`POST /v1/chat/completions`。
+- 生命周期：同步响应。
+
+## 配置字段
+
+| 字段 | 类型 | 必填 | 含义 |
+| --- | --- | --- | --- |
+| `apiKey` | secret | 是 | API Key |
+
+## 统一字段映射
+
+| 统一字段 | 类型 | 必填 | 上游映射 | 说明 |
+| --- | --- | --- | --- | --- |
+| `model` | string | 是 | `model` | 上游模型 ID。 |
+| `messages` | message[] | 是 | `provider message container` | 包含历史消息和当前用户输入。 |
+| `instructions` | string | 否 | `system/instructions` | 系统指令。 |
+| `temperature` | number | 否 | `temperature` | 采样温度。 |
+| `top_p` | number | 否 | `top_p` | 核采样参数。 |
+| `max_tokens` | integer | 否 | `max_tokens/max_output_tokens` | 最大输出 token。 |
+| `tools` | array | 否 | `tools/toolConfig` | 工具定义。 |
+| `tool_choice` | object|string | 否 | `tool_choice` | 工具选择策略。 |
+| `response_format` | object | 否 | `response_format/text` | 结构化输出配置。 |
+| `stream` | boolean | 否 | `stream` | 流式开关；后台任务当前以最终响应归一。 |
+
+## 上游请求模板逐字段清单
+
+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。
+
+| 上游位置 | 值或转换表达式 |
+| --- | --- |
+| `create.method` | `"POST"` |
+| `create.path` | `"/v1/chat/completions"` |
+| `create.contentType` | `"application/json"` |
+| `create.body.model` | `{"$ref":"request.model"}` |
+| `create.body.messages` | `{"$ref":"request.messages"}` |
+| `create.body.temperature` | `{"$omitEmpty":{"$ref":"request.providerOptions.atlascloud-chat.temperature"}}` |
+| `create.body.top_p` | `{"$omitEmpty":{"$ref":"request.providerOptions.atlascloud-chat.top_p"}}` |
+| `create.body.max_tokens` | `{"$omitEmpty":{"$coalesce":[{"$ref":"request.extra.max_tokens"},{"$ref":"request.providerOptions.atlascloud-chat.max_tokens"}]}}` |
+| `create.body.tools` | `{"$omitEmpty":{"$ref":"request.providerOptions.atlascloud-chat.tools"}}` |
+| `create.body.tool_choice` | `{"$omitEmpty":{"$ref":"request.providerOptions.atlascloud-chat.tool_choice"}}` |
+| `create.body.response_format` | `{"$omitEmpty":{"$ref":"request.providerOptions.atlascloud-chat.response_format"}}` |

+| `create.body.extra_body` | `{"$omitEmpty":{"$ref":"request.providerOptions.atlascloud-chat.extra_body"}}` |
+| `agent.method` | `"POST"` |
+| `agent.path` | `"/v1/chat/completions"` |
+| `agent.contentType` | `"application/json"` |
+| `agent.body` | `{"$merge":[{"$ref":"request.extra.agent.chatCompletion"},{"model":{"$ref":"request.model"}}]}` |
+
+## Provider 扩展键
+
+- `providerOptions.atlascloud-chat.extra_body`
+- `providerOptions.atlascloud-chat.max_tokens`
+- `providerOptions.atlascloud-chat.provider`
+- `providerOptions.atlascloud-chat.response_format`
+- `providerOptions.atlascloud-chat.stream`
+- `providerOptions.atlascloud-chat.temperature`
+- `providerOptions.atlascloud-chat.tool_choice`
+- `providerOptions.atlascloud-chat.tools`
+- `providerOptions.atlascloud-chat.top_p`
+- `providerOptions.atlascloud-chat.transforms`
+
+动态模型或工作流允许使用文档声明的完整 `parameters/input/extra_body` 对象；该对象是协议本身的开放 schema，不会被宿主裁剪。
+
+## 响应映射逐字段清单
+
+| 映射位置 | 上游路径或转换表达式 |
+| --- | --- |
+| `response.status` | `"succeeded"` |
+| `response.textPaths[0]` | `"choices.0.message.content"` |
+| `response.textPaths[1]` | `"choices.0.text"` |
+| `response.reasoningPaths[0]` | `"choices.0.message.reasoning_content"` |
+| `response.usage` | `{"$ref":"response.usage"}` |
+| `response.errorPaths[0]` | `"error.code"` |
+| `response.messagePaths[0]` | `"error.message"` |
+| `agentResponse.textPaths[0]` | `"choices.0.message.content"` |
+| `agentResponse.textPaths[1]` | `"choices.0.text"` |
+| `agentResponse.reasoningPaths[0]` | `"choices.0.message.reasoning_content"` |
+| `agentResponse.toolCallsPath` | `"choices.0.message.tool_calls"` |
+| `agentResponse.toolCallIdPaths[0]` | `"id"` |
+| `agentResponse.toolCallNamePaths[0]` | `"function.name"` |
+| `agentResponse.toolCallArgumentsPaths[0]` | `"function.arguments"` |
+
+## 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
+
+该插件实现该平台公开的 OpenAI Chat Completions 线协议 profile；平台专有字段通过 providerOptions 命名空间透传，未声明支持的 OpenAI 字段仍由模型 capability profile 校验。
