+# Aide 项目概览
+
+本仓库包含三部分产物：
+- **aide-marketplace/**：Claude Code 插件目录（commands + skills）
+- **aide-program/**：aide 程序实现（本阶段提供初始化、配置与环境管理）
+- **ai-agent-memory/** & **docs/**：原始流程文档与参考资料
+
+当前完成情况：插件与文档已就绪，aide 程序已实现基础 CLI，后续将补充 `aide flow` 与 `aide decide` 细节。
+
+## 快速开始（aide 程序）
+
+### 环境准备
+1. 确认已安装 `uv`（0.9+）。
+2. 在仓库根目录创建虚拟环境并安装依赖：
+   ```bash
+   uv venv .venv
+   uv pip install -r requirements.txt --python .venv
+   ```
+
+### 可用命令
+- 初始化配置与 .aide 目录（会写入 `.gitignore`）  
+  ```bash
+  ./aide-program/aide.sh init
+  ```
+- 检测运行时环境（不读取配置）  
+  ```bash
+  ./aide-program/aide.sh env ensure --runtime
+  ```
+- 检测项目环境，确保 `.venv`、`requirements`、任务文档路径等  
+  ```bash
+  ./aide-program/aide.sh env ensure
+  ```
+- 读取/设置配置（示例）  
+  ```bash
+  ./aide-program/aide.sh config get task.source
+  ./aide-program/aide.sh config set task.spec task-spec.md
+  ```
+
+> Windows 可使用 `aide-program\\aide.bat`，命令参数一致。
+
+### 配置文件
+`aide init` 会生成 `.aide/config.toml`，默认字段：
+- `runtime.python_min`：最小 Python 版本（默认 3.11）
+- `task.source` / `task.spec`：任务原文档与细则文档默认路径
+- `env.venv` / `env.requirements`：虚拟环境与依赖文件位置
+- `flow.phases`：流程环节名称（flow/decide 功能尚未实现）
+
+## 未完成功能
+- `aide flow` 进度追踪、`aide decide` 待定项 Web 界面尚未实现，后续阶段补充。
+- 配置写入时暂不保留注释，必要时可重新运行 `aide init` 重置为模板后再调整。
+
+## 参考
+- 需求规格：`aide-requirements.md`
+- 设计讨论：`discuss/` 目录（Phase 1/2 已完成，当前进入程序实现阶段）

+# 背景与范围
+
+- 已审阅 `aide-requirements.md`、`ai-agent-memory/` 全部文件、`docs/` 全部文件、`aide-marketplace/` 现有 commands 与 SKILL、`discuss/01-03`、`reply/re-03.md`、`CLAUDE.md`/`AGENTS.md`。当前 Phase1/2 已完成，re-03 调整已落实。
+- 任务：在 `aide-program/` 下实现 aide 程序系统的入口封装与 Python 核心功能，**暂不实现/细化 aide flow 与 aide decide**。
+
+# 设计聚焦
+
+- 入口封装：提供 `aide.sh`、`aide.bat` 调用 `.venv` 下的 Python，执行 `python -m aide`。
+- CLI 范围（本阶段）：`aide init`、`aide env ensure [--runtime]`、`aide config get/set`。flow/decide 仅预留配置，不实现逻辑。
+- 输出规范：统一使用 `✓/⚠/✗/→` 前缀，遵循“静默即成功”原则，中文提示。
+- 配置管理：`.aide/config.toml`，默认包含 `runtime`（python_min）、`task`（source/spec 默认 `task-now.md`/`task-spec.md`）、`env`（venv/requirements）、`flow.phases`。支持 `config get/set`，缺失时自动创建默认配置与 `.aide/` 目录。
+- 环境检测：
+  - `--runtime`：检测 Python 版本、`uv` 可用性，不读配置。
+  - 完整 `ensure`：读取配置，确保 `.aide/` 结构、`.gitignore` 条目、`.venv`（用 `uv venv` 创建）、`requirements.txt` 存在并通过 `uv pip install -r` 安装依赖，输出任务文档路径提示。
+- 依赖：尽量标准库，TOML 写入使用轻量依赖 `tomli-w`，列入 `requirements.txt` 并通过 uv 安装。

+# 开发计划
+
+1) 初始化 `aide-program/` 目录与入口脚本骨架；补充 `requirements.txt`、`.venv`（已建）。  
+2) 实现核心模块：输出工具、配置管理、环境检测、CLI 路由。  
+3) 补充根级 `README.md`，描述用法/约束/未实现部分；必要自检（使用 `.venv/bin/python -m aide ...`）。  
+4) 暂不实现 flow/decide 细节，后续再扩展。
+
+# 实施进展（同步）
+
+- 已创建 `aide-program/` 目录与入口脚本（bash/bat），通过 `.venv` 调用 `python -m aide`。
+- 实现模块：`core/output.py`（统一输出）、`core/config.py`（默认配置生成、读取/写入、.gitignore 维护）、`env/ensure.py`（runtime 检查、venv/依赖处理）、`main.py`（init/env/config CLI）。
+- 生成默认配置 `.aide/config.toml`，补充 `.gitignore`，`requirements.txt` 添加 `tomli-w` 并通过 uv 安装。
+- 自检：`aide init`、`aide env ensure --runtime`、`aide env ensure`、`aide config get task.source` 均通过，输出符合 `✓/⚠/✗/→` 规范。
