c6b3beee5e Add tool search to Copilot agent host (#326213)
* Add tool search to Copilot agent host

* Address review: alias-aware tool-search gating, drop transient candidates, cover prompt branch

- Compute the tool-search capability decision from the family-aliased model in
  both the launcher and CopilotAgentSession so an aliased preview model is no
  longer rejected and the two stay in agreement.
- Strip the transient tool-search candidate corpus from the completed tool
  call's _meta so repeated searches don't bloat synchronized session state or
  persist across reconnects.
- Add active/inactive + composition tests for the tool-search prompt line at
  both the unit and prompt-registry layers, plus a model-family alias
  regression test for tool-search gating.

* Remove obsolete tool-search start barrier

* Address tool-search review feedback

* Use the extension's existing tool-embedding cache for Agent Host search

* Address review: keep server tools eager, harden tool-search candidate corpus

- Force server-provided SDK tools to defer:'never' so they stay eager and are
  not deferred behind tool_search.
- Default missing candidate descriptions to '' when building the tool-search
  corpus, so the all-or-nothing metadata reader never drops a valid corpus.
- Drop the unused inputSchema field from the tool-search candidate corpus
  (name + description are all the embeddings ranker consumes).
- Use the client-facing tool name in the custom-tool auto-approve membership
  check so a deferred tool_search runtime name resolves correctly.
- Remove a redundant conjunct in _clientToolName already implied by
  _isToolSearchActive().

Visual Studio Code - Open Source ("Code - OSS")

Feature Requests Bugs Gitter

The Repository

This repository ("Code - OSS") is where we (Microsoft) develop the Visual Studio Code product together with the community. Not only do we work on code and issues here, but we also publish our roadmap, monthly iteration plans, and our endgame plans. This source code is available to everyone under the standard MIT license.

Visual Studio Code

VS Code in action

Visual Studio Code is a distribution of the Code - OSS repository with Microsoft-specific customizations released under a traditional Microsoft product license.

Visual Studio Code combines the simplicity of a code editor with what developers need for their core edit-build-debug cycle. It provides comprehensive code editing, navigation, and understanding support along with lightweight debugging, a rich extensibility model, and lightweight integration with existing tools.

Visual Studio Code is updated monthly with new features and bug fixes. You can download it for Windows, macOS, and Linux on Visual Studio Code's website. To get the latest releases every day, install the Insiders build.

Contributing

There are many ways in which you can participate in this project, for example:

If you are interested in fixing issues and contributing directly to the code base, please see the document How to Contribute, which covers the following:

Feedback

See our wiki for a description of each of these channels and information on some other available community-driven channels.

Many of the core components and extensions to VS Code live in their own repositories on GitHub. For example, the node debug adapter and the mono debug adapter repositories are separate from each other. For a complete list, please visit the Related Projects page on our wiki.

Bundled Extensions

VS Code includes a set of built-in extensions located in the extensions folder, including grammars and snippets for many languages. Extensions that provide rich language support (inline suggestions, Go to Definition) for a language have the suffix language-features. For example, the json extension provides coloring for JSON and the json-language-features extension provides rich language support for JSON.

Development Container

This repository includes a Visual Studio Code Dev Containers / GitHub Codespaces development container.

  • For Dev Containers, use the Dev Containers: Clone Repository in Container Volume... command which creates a Docker volume for better disk I/O on macOS and Windows.

    • If you already have VS Code and Docker installed, you can also click here to get started. This will cause VS Code to automatically install the Dev Containers extension if needed, clone the source code into a container volume, and spin up a dev container for use.
  • For Codespaces, install the GitHub Codespaces extension in VS Code, and use the Codespaces: Create New Codespace command.

Docker / the Codespace should have at least 4 cores and 6 GB of RAM (8 GB recommended) to run a full build. See the development container README for more information.

Code of Conduct

This project has adopted the Microsoft Open Source Code of Conduct. For more information see the Code of Conduct FAQ or contact opencode@microsoft.com with any additional questions or comments.
