+
+---
+
+## 进行中 🚧
+
+暂无。
+
+---
+
+## 计划中 📋
+
+### 1. Git 凭证管理器
+
+将 Git 凭证管理集成到 QuiCommit 中，统一管理 HTTPS 仓库的身份认证。
+
+- [ ] **Git Credential Helper 集成**
+  - 实现 `git credential-store` / `git-credential-libsecret` 等标准的 credential helper 协议
+  - 支持 `quicommit credential get|store|erase` 子命令
+  - 与系统密钥环无缝对接，复用已有的 `KeyringManager`
+
+- [ ] **凭证管理 CLI**
+  - `quicommit credential list` — 列出所有已存储的凭证
+  - `quicommit credential add` — 手动添加凭证（用户名 + 密码/Token）
+  - `quicommit credential remove` — 删除指定凭证
+  - `quicommit credential status` — 查看凭证管理状态
+
+- [ ] **跨平台支持**
+  - Windows：集成 Windows Credential Manager
+  - macOS：集成 Keychain
+  - Linux：通过 Secret Service / D-Bus 对接 GNOME Keyring / KWallet
+
+- [ ] **安全增强**
+  - 支持 PAT（Personal Access Token）按 scope / 有效期管理
+  - 支持凭证过期检查和自动提醒
+
+---
+
+### 2. 新增模型支持
+
+扩展 LLM 提供商和模型覆盖范围，满足更多场景和偏好。
+
+- [x] **新增 DeepSeek 最新模型**
+  - 支持 `deepseek-chat`（DeepSeek-V3）
+  - 支持 `deepseek-reasoner`（DeepSeek-R1）
+  - 支持 `deepseek-v4`
+
+- [ ] **新增国内模型提供商**
+  - 通义千问 (Qwen) — 阿里云 DashScope API
+  - 文心一言 (ERNIE) — 百度千帆 API
+  - 智谱 GLM — ChatGLM API
+  - 百川 (Baichuan) — Baichuan API
+
+- [ ] **新增国际模型提供商**
+  - Google Gemini API
+  - Mistral AI API
+  - Cohere API
+  - Groq (LPU 推理加速)
+
+- [ ] **本地模型扩展**
+  - 支持 llama.cpp 服务端（兼容 OpenAI API 格式）
+  - 支持 vLLM 部署的模型
+  - 本地模型推荐列表与一键配置向导
+
+- [ ] **模型能力适配**
+  - 不同模型的 token 限制自适应
+  - 模型特定的 prompt 模板优化
+  - 支持 function calling / tool use（用于复杂生成场景）
+
+---
+
+### 3. 生成体验优化
+
+提升 AI 生成提交信息、标签说明和变更日志时的用户体验。
+
+- [x] **流式输出与实时反馈**
+  - 支持 SSE（Server-Sent Events）流式生成
+  - 终端打字机效果实时显示生成内容
+  - 流式生成过程中支持 `Ctrl+C` 中断
+
+- [ ] **生成质量提升**
+  - 基于 commitlint 规则的后校验与自动修正
+  - 支持 Few-shot 示例引导（用户可自定义示例库）
+  - 生成结果的置信度评分与多候选方案
+
+- [ ] **Diff 上下文增强**
+  - 智能 diff 摘要（大改动时自动压缩关键信息）
+  - 支持 `.gitattributes` 排除/包含规则
+  - 按文件类型分组生成更精准的提交描述
+
+- [ ] **交互式编辑增强**
+  - 生成后支持内联编辑（类似 `git rebase -i` 体验）
+  - 支持重新生成指定部分（如 scope、description）
+  - 历史提交信息学习与风格适配
+
+- [ ] **批量操作支持**
+  - 批量生成多个 commit（分组暂存区变更）
+  - `--dry-run` 预览模式（只生成本地查看，不写 Git）
+
+- [ ] **性能优化**
+  - API 请求并发优化（多个模型同时生成候选）
+  - 本地缓存常用 prompt 模板
+  - 减少不必要的 diff 计算
+
+---
+
+## 长远规划 🌟
+
+- [ ] **VS Code 扩展** — 在 IDE 内直接使用 QuiCommit
+- [ ] **GitHub Action / GitLab CI 集成** — 自动化 PR 标题和描述生成
+- [ ] **团队协作** — 共享 commit 风格配置、prompt 模板库
+- [ ] **Web Dashboard** — 可视化管理多仓库的 Git 活动与 AI 生成统计
+- [ ] **插件系统** — 允许社区贡献自定义 LLM 提供商和生成策略
