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。

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.
