Release v1.0.3

中文

新特性

• Graph CLI Catalog Commands: 为 atac graph 新增 list、get 和 run 子命令，支持直接从 ATAC_DIR 列出可用 graph、读取 graph 元信息，以及按 graph 名称运行已保存流程。

变更

• Graph Execution UX: atac graph run 现在同时支持 <module>:<factory> 和已保存的 graph 名称；当提供 --atac-dir 或设置 ATAC_DIR 时，会优先按 graph 目录解析并执行。

English

Features

• Graph CLI Catalog Commands: Added list, get, and run subcommands under atac graph, allowing users to list saved graphs from ATAC_DIR, inspect graph metadata, and run graphs by saved name.

Changed

• Graph Execution UX: atac graph run now supports both <module>:<factory> specs and saved graph names. When --atac-dir or ATAC_DIR is provided, graph execution can resolve directly from the saved graph directory.

Release v1.0.2

中文

新特性

• Async Bootstrap Support: 新增异步 bootstrap 加载链，ATAC_BOOTSTRAP 现在可以返回异步创建的 AtacService，便于在运行时自然接入异步 MCP client 和其他异步初始化逻辑。
• Bulk LangGraph Registration: AtacService 新增 register_langgraph_tools(...)，支持批量注册原生 LangGraph / LangChain tools，并保持和已有单个注册接口兼容。
• Registered Agent Access: AtacService 新增 register_agent(...)、get_agent(...) 和 list_agents()，graph 节点现在可以通过 get_service().get_agent() 访问预注册 agent。
• Graph Audit Analyzer: 新增静态分析 API，可从 graph 源码或 graph spec 中提取可审计结构，包括节点、连线、工具调用、agent 调用和源码片段。
• Packaged Audit UI: 新增基于 React Flow 的审计前端，并提供 atac ui 命令直接启动内置静态页面，无论用户通过源码运行还是 uv tool install atac 安装都可直接使用。

变更

• Audit UI Delivery: 前端构建产物现在默认输出到 src/atac/ui_dist 并作为包数据发布，atac ui 会直接从安装包内读取静态资源。
• Audit UI Refresh: 新审计前端使用浅色极简布局、流程概览、节点详情、源码弹窗和语法高亮，替换旧的遗留 UI 前端。

移除

• Legacy UI Frontend: 删除历史遗留的旧 UI 前端代码，统一收敛到新的 packaged audit UI。

English

Features

• Async Bootstrap Support: Added an async bootstrap loading path so ATAC_BOOTSTRAP can now return an asynchronously created AtacService, making it easier to initialize async MCP clients and other async runtime dependencies.
• Bulk LangGraph Registration: Added AtacService.register_langgraph_tools(...) for bulk registration of native LangGraph / LangChain tools while keeping the existing single-tool registration path intact.
• Registered Agent Access: Added register_agent(...), get_agent(...), and list_agents() to AtacService, allowing graph nodes to access pre-registered agents through get_service().get_agent().
• Graph Audit Analyzer: Added a static graph audit API that extracts auditable structure from graph source or graph specs, including nodes, edges, tool calls, agent calls, and source snippets.
• Packaged Audit UI: Added a React Flow-based audit frontend plus an atac ui command that launches the bundled static app directly, whether the user runs from source or installs with uv tool install atac.

Changed

• Audit UI Delivery: Frontend build output now targets src/atac/ui_dist by default and is shipped as package data, so atac ui can serve assets directly from the installed package.
• Audit UI Refresh: The new audit frontend uses a light minimal layout with flow overview, node inspection, modal code viewing, and syntax highlighting, replacing the previous legacy UI frontend.

Removed

• Legacy UI Frontend: Removed the historical legacy UI frontend so the new packaged audit UI is now the single supported UI surface.

Release v1.0.1

中文

新特性

• ATaC MCP Graph Catalog: atac mcp 现在要求通过 ATAC_DIR 指定 graph 存储目录，并新增 save_graph、list_graph、get_graph 三个工具，支持 graph 资产的保存、发现和读取。
• Graph Metadata Contract: save_graph 现在要求同时提供 inputs、outputs 和 example_state，让 graph 描述可以直接服务于 Agent 的发现和复用。
• Graph Name Resolution: run_graph 现在除了 <module>:<factory> 形式外，也支持直接传入 graph 名称，并自动解析到 <name>.graph:build_graph。

变更

• Raw MCP Tool Names by Default: MCP 工具默认使用原始工具名注册，不再默认附加 mcp. 前缀，减少 Agent 可见名称和 ATaC 注册名称不一致的问题。
• Selective Graph Retrieval: get_graph 默认只返回 description.yaml 元信息，显式传入 include_code=true 时才返回 graph.py 源码。
• Tool Guidance: save_graph 的工具说明补充了最小 graph 模板和编写约束，帮助 Agent 生成可加载的 graph 代码。

修正

• Async MCP Graph Execution: 修复了 atac mcp 在事件循环中执行异步 graph 时触发 Cannot invoke async graph while an event loop is already running 的问题。

English

Features

• ATaC MCP Graph Catalog: atac mcp now requires ATAC_DIR for graph storage and adds save_graph, list_graph, and get_graph for persisting, discovering, and inspecting reusable graphs.
• Graph Metadata Contract: save_graph now requires inputs, outputs, and example_state so graph descriptions can be consumed directly by agents.
• Graph Name Resolution: run_graph now accepts either <module>:<factory> or a plain graph name, resolving the latter to <name>.graph:build_graph.

Changed

• Raw MCP Tool Names by Default: MCP tools now register under their raw names by default instead of automatically adding an mcp. prefix, keeping agent-visible and ATaC-registered names aligned.
• Selective Graph Retrieval: get_graph now returns only description.yaml metadata by default and includes graph.py source only when include_code=true is requested.
• Tool Guidance: Expanded the save_graph tool description with a minimal graph template and authoring constraints to improve first-pass graph generation.

Fixed

• Async MCP Graph Execution: Fixed atac mcp so async graphs can run inside an active event loop without raising Cannot invoke async graph while an event loop is already running.

• ATaC Memory MCP: memory_run_command 会自动切换到目标记忆目录作为工作目录，并阻止绝对路径或越界路径逃逸出 memory bundle。

English

Features

• ATaC Memory MCP: Added memory_run_command(memory_name, command, args) to run a relative command inside a selected memory bundle directory.
• ATaC Memory MCP: memory_run_command now uses the target memory bundle as its working directory and rejects absolute or path-escaping command targets.

Release v0.4.6

中文

新特性

• ATaC Memory MCP: memory-mcp 现支持通过 --memory-dir 指定记忆目录。
• ATaC Memory MCP: 记忆目录优先级为 --memory-dir > ATAC_MEMORY_DIR > .atac/.memory，便于在不同工作区和独立部署场景下复用 memory 服务。

English

Features
