-# Prompts-Core（提示词核心服务）
-
-> 智能提示词构建与管理系统，支持多模态 AI 模型的提示词组装、会话管理和协议适配。
-
----
-
-## 项目简介
-
-**Prompts-Core** 是一个基于 Go 语言开发的提示词核心服务，作为 AI 应用层与模型网关之间的桥梁，负责将业务需求转换为标准化的模型请求。
-
-### 核心价值
-- **统一提示词管理**：集中化管理不同模型类型的提示词模板
-- **智能会话维护**：基于 Redis + PostgreSQL 的双层会话存储
-- **多协议适配**：支持 OpenAI、DeepSeek、Qwen、Gemini 等多种模型协议
-- **文件处理能力**：自动提取文本文件和 ZIP 压缩包内容
-- **技能系统集成**：支持从外部加载 Markdown 格式的技能描述
-
----
-
-## 核心功能
-
-### 1. 提示词构建引擎
-
-#### 多模态支持
-| 类型 | 说明 | 适用场景 |
-|------|------|----------|
-| Type 1 | 文字处理助手 | 文章撰写、文案优化、翻译等 |
-| Type 2 | 图片处理助手 | 图像生成、风格迁移等 |
-| Type 3 | 音频处理助手 | 语音合成、识别、降噪等 |
-| Type 4 | 向量化处理助手 | 语义检索、知识索引等 |
-| Type 5 | 全模态助手 | 跨模态转换、多模态融合等 |
-
-#### 构建模式
-- **BuildType 1（提示词构建）**：完整流程，包含系统提示词、历史会话、用户输入的智能组装
-- **BuildType 2（节点构建）**：工作流路由决策，根据上下文选择节点 ID
-
-#### 分批处理
-当用户表单内容超出模型窗口限制时，自动按 Token 大小分批处理。
-
-### 2. 会话管理系统
-
-- **双层存储**：Redis 缓存（最近 N 轮）+ PostgreSQL 持久化
-- **自动管理**：最大轮数控制（默认 10 轮）、自动过期（默认 30 分钟）
-
-### 3. 协议适配器
-
-通过配置动态支持多种模型协议：
-- 角色映射：system/user/assistant → 目标协议角色
-- 内容字段映射：content → parts.text 等
-- 消息顺序控制：灵活配置拼接顺序
-- 请求模板渲染：支持占位符替换
-
-### 4. 任务调度
-
-- **异步流程**：创建网关任务 → 轮询等待 → 接收回调 → 返回结果
-- **重试机制**：可配置最大重试次数（默认 3 次）
-- **超时保护**：默认 300 秒超时
