Update with upstream 1.62.2 (#1) * fix: autocomplete content in chat view (#15240) Fixes autocomplete content not showing up in inline editors like the ChatInput. With the Lumino migration we disabled 'fixedOverflowWidgets' in our Monaco editors, as Lumino widget styles leverages 'contain', influencing the position of autocomplete content. This is now reverted, and instead the 'contain' of Lumino widgets is forcefully disabled, fixing the autocomplete issue. fixes #15237 Co-authored-by: Eugen Neufeld * Limit the width of tab-bar rows to 100% of parent (#15260) Fixes #15254 Contributed on behalf of STMicroelectronics Signed-off-by: Thomas Mäder * Refine AI setting descriptions (#15250) * Add shortcut for adding the current file to the AI chat context (#15252) * fix: Pin node-abi version to 3.x due to Node.js 22+ requirement in 4.x (#15212) * pins the node-abi version to resolve the compatibility issue where node-abi 4.x requires Node.js version 22 or higher * remove unused package node-abi @types/node-abi * update package-lock.json after delete node-abi * Prevent plugin host localization errors (#15268) * Allow to add all MCP functions via prompt fragment (#15270) fixed #14952 * [vscode] Support keepWhitespace in SnippetTextEdit and insertSnippet (#15176) fixes #15131 Contributed on behalf of STMicroelectronics Signed-off-by: Remi Schnekenburger * Workspace Symbols: Pass multiple classnames as array of strings (#15244) * Dispose of child InstantiationServices in MonacoEditor (#15246) * Add news section with AI to welcome page (#15269) * Add news section with AI to welcome page * chore: make parameters in ToolRequest mandatory (#15288) Previously, parameters were optional, indicating that a tool request doesn’t take any.

Obfuscates tokens (very basic support). - Shows the status of a server (Running, Starting, Errored, Not Running). - Shows all tools available. Let's the user easily copy the tools for chat and prompttemplate use. - Offers a button to start/stop the view. Fix autostart stopping for following servers if one fails: - Before this the autostart would stop for all following servers if one failed. - This was due to uncatched errors when trying to resolve the tools. - To prevent this in the future, improved the handling of the getTools() on client side. - Also adapted the Start Command to use the new status reporting instead of calling getTools() again.

Centralizes all LLM communication via the new LanguageModelService. Leveraging this service, adopters can easily customize LLM request handling. Greatly enhances the model request settings, allowing configuration of default request settings for LLM providers, specific LLM models and agents. The request settings are merged with the handed over request settings via the new LanguageModelService. Additionally, request settings can now be set per session via the Chat UI, which is useful for quick experimentations, eliminating the need to manually modify preferences.

It'd be better to use a language model to generate a name for the chat session and also record the last interaction date, to have proper sorting and a chronological relation to the chat sessions. Moreover, this PR allows users to manually specify a name for the chat session, which will be used instead of the generated name.

This includes customization's (will be forwarded to the customization service, if one exists). Also handles the newly introduced agent prompts. Changed agents prompts declaration: - Agent now provide the id of the system prompt they are using. - Additionally they need to define the default variant, but can register many more variants. Improved logic in prompt-service: - Added listener when the prompts have changed - Removed as much assumed information about the customization service as possible (e.g. file name) - Added PromptVariantSets, selected & active variant maps to keep the state. - Introduces types for BuiltInPromptFragment & CustomizedPromptFragment. Introduces a new widget for configuring AI prompt fragments and PromptVariantSets. Displays all PromptVariantSets, which agent they are used by, their variants and customizations. Shows the active and selected variants as well as the active customization. Offers buttons to revert to a certain customization or deleting it. Allows the user to create a customization of built-in prompt fragents. Displays the template text for each customization.

Also updates token tracking functionality to be aware of token caching and updates the Anthropic SDK. fixes #15729 * Fix chat input widget not tracking branches and pending state (#15727) Update the ChatInput widget to - track the currently active branch in the session tree - listen for state changes in the model to show either the cancel button when a request is pending or else the send button Co-authored-by: Christian W. Damus * Tool Call Confirmation UI (#15714) This PR introduces a flexible and user-configurable tool call confirmation system for agent interactions. Users can now control, on a per-tool basis, whether a tool call should be: - **Disabled**: The tool cannot be executed. - **Confirm**: The user is prompted for approval each time the tool is called. - **YOLO**: The tool is executed immediately without confirmation. **Features:** - **Per-Tool Confirmation Settings:** Users can configure the confirmation mode for each tool individually, either via the AI configuration view (dropdown per tool) or directly in `settings.json`. - **Session and Persistent Preferences:** When prompted, users can approve or deny a tool call once, for the entire chat session, or persist their preference (including disabling or enabling YOLO mode) in their settings. - **Default Mode:** The default mode is YOLO, but users can set their own global default. - **Configuration UI:** Added a dedicated view for managing tool confirmation settings, making it easy to adjust preferences per tool.

Since the menu refactoring in #14676, this workaround is no longer needed. In fact, it now causes issues like empty submenus appearing in context menus. Removing the workaround fixes this regression.

Furthermore only waiting for success and error together was used until now. Signed-off-by: Florian Richter * fix: sync selection if props change (#15784) Class components do not re-run constructors on prop changes. This meant that `defaultValue` and `options` were only evaluated once during the initial mount. As a result, dynamic updates to the selected channel did not reflect in the SelectComponent UI. This change extracts the selected index logic into a helper method and calls it from both the constructor and `componentDidUpdate` to keep state in sync with prop changes, mimicking behavior of function components using hooks. Closes: eclipse-theia/theia#15769 * Remind coder to use file change functions (#15848) * Cancel hover preview on right/middle mouse click (#15826) This prevent overlap with e.g. menus. Cancels the hover preview when a right or middle mouse button is pressed. Left-clicks are not handled, as the event does not propagate, but this is not critical since left-clicking typically changes the UI and dismisses the hover naturally.
