+## AI 智能体改进
+
+- **更智能的上下文感知**：AI 现在在你 @提及仓库时自动理解仓库上下文，包含名称、描述和默认分支等信息。
+- **实时事件推送**：新增 WebSocket 事件支持，当 AI 配置变更或仓库创建、重命名、删除时，界面实时同步更新。
+- **修复模型同步问题**：解决了上游模型同步 URL 路径重复的问题。
+
+## 前端
+
+- **更好的自动补全**：@提及建议现在显示仓库类型，方便快速定位目标仓库。
+- **连接恢复能力**：WebSocket token 在断连后自动刷新，AI 和实时功能平滑恢复。
+
+## 可观测性
+
+- **人性化日志**：终端会话现在使用可读的日志格式，服务器环境仍保留 JSON 格式。
+
+## 性能与稳定性
+
+- **内存泄漏修复**：解决了聊天服务中的两个内存泄漏问题。
+- **缓存优化**：聊天和工作空间缓存在相关事件发生时正确刷新。

+## AI Agent Improvements
+
+- **Smarter context**: AI now automatically understands which repository you're talking about when you @mention it, with full context including description and default branch.
+- **Real-time updates**: New WebSocket events keep the UI in sync when AI configs change or repositories are created, renamed, or deleted.
+- **Fixed model sync**: Resolved an issue where the upstream model sync URL would contain a duplicate path segment.
+
+## Frontend
+
+- **Better autocomplete**: @mention suggestions now show the repository type, making it easier to find the right repo.
+- **Connection resilience**: WebSocket token now auto-refreshes after disconnection, so AI and real-time features recover smoothly.
+
+## Observability
+
+- **Human-friendly logs**: Terminal sessions now use readable log formatting. JSON format is preserved for server environments.
+
+## Performance & Stability
+
+- **Memory leak fixes**: Resolved two memory leaks in the room service.
+- **Cache improvements**: Room and workspace caches now properly refresh on relevant events.

+## AI Agent — Built-in Skills System
+
+We've launched a built-in skills system with 16 pre-configured skills. The AI automatically matches and activates the right skill based on conversation context:
+
+**Git Operations**
+- Commit history analysis — view project evolution, search commits, visualize branch graphs
+- Code change analysis — compare diffs, summarize changes, trace code authorship
+- Branch management — list branches, check merge status, analyze sync state
+
+**Code Quality**
+- Code review — professional review covering security, performance, and best practices
+- Code explainer — clarify complex code in plain language
+
+**Project Management**
+- Repository management — browse, create, and configure project repos
+- Issue management — full workflow with triage, labels, and priority assessment
+- Board management — organize kanban boards, manage cards, track progress
+- Member management — view team structure, manage roles and permissions
+
+**Developer Productivity**
+- PR summary — auto-generate clear and concise PR descriptions
+- Issue triage — intelligently classify issue type, priority, and component
+- Documentation generator — create README, API docs, and inline docs
+- Test generator — write well-structured unit tests
+- Commit message generator — auto-generate conventional commit messages
+
+**Utility**
+- HTTP requester — API testing and debugging
+
+All built-in skills are available to every project by default. Use `@skill-name` or natural language to activate them. Project admins can customize or override them.
+
+## AI — Model Sync
