JetBrains 为 MPS 2026.1.1、2025.3.2、2025.2.4 和 2025.1.4 发布修复更新。其中 2026.1.1 的 Projectional Agent Toolkit 获得多项改进：agent 可查看并调用单个节点上的 intentions 与 quick-fixes、操作 NodeAttributes 和 PropertyAttributes 等、创建节点副本、获取包含光标与选区信息的更丰富编辑器上下文，并在模态对话框阻塞工具执行时收到明确诊断；同时扩展了编辑器测试、YouTrack 建单和可靠测试执行方面的 agent 指引。官方提示用户让 agent 更新项目中的 MPS skills 以充分利用变更。
AI推荐理由 JetBrains 官方发布 MPS 多个版本的 bug 修复更新，其中 2026.1.1 的 Projectional Agent Toolkit 新增了让 agent 查看并调用节点上的 intentions/quick-fixes、操作 NodeAttributes、复制节点、获取更丰富编辑器上下文（光标与选区）以及在模态对话框阻塞时给出明确诊断等能力，并扩展了编辑器测试、YouTrack 建单和测试执行的 agent 指引。这是官方一手信息、事实明确，但属于常规维护性发布，对非 MPS 用户价值有限，且未提供效果数据。

We’ve released updates for multiple major MPS versions that fix several issues. DOWNLOAD MPS 2026.1.1 Check out all the updates in each particular version below: MPS 2026.1.1 The Projectional Agent Toolkit receives several practical improvements that allow agents to: See and invoke intentions and quick-fixes on individual nodes. Manipulate NodeAttributes, PropertyAttributes, and others. Create copies of nodes. Obtain richer editor context, including caret and selection information. Receive clear diagnostics when modal dialogs block tool execution. The release also expands agent guidance for editor tests, YouTrack issue creation, and reliable test execution. Together, these updates make agent-assisted projectional development more capable, predictable, and easier to operate. Note: Remember to ask your agent to update the MPS skills in your project to benefit most from the changes. Download MPS 2026.1.1 here. See the full list of fixed issues here.
