Rob Lourens e0c3dafcdb Reuse PermissionPickerActionItem for agent host auto-approve picker (#311263)
* Reuse PermissionPickerActionItem for agent host auto-approve picker

Previously the agent host had its own custom auto-approve picker that
duplicated most of the workbench PermissionPickerActionItem widget. This
refactor reuses the workbench widget when the active session's
autoApprove session-config property uses the well-known schema (string
type, enum subset of {default, autoApprove, autopilot} containing
'default'). Sessions that match get the workbench widget; non-conforming
agents fall back to the existing generic per-property picker.

- Adds AgentHostPermissionPickerDelegate and a thin
  AgentHostPermissionPickerActionItem subclass that toggles its
  visibility reactively as the active session changes.
- Generalizes the warning/info color rules in chat.css so they live
  with the widget rather than being scoped to .chat-secondary-toolbar.
- Groups all agent-host-only files under
  src/vs/sessions/contrib/chat/browser/agentHost/.
- Fixes a regression where the picker would stay hidden after
  navigating back to the new-chat view; the IActionViewItemService
  factory only runs once per render, so visibility must be reactive
  rather than gated at construction.

* Refactor: agent host reuses PermissionPicker (sessions) instead of PermissionPickerActionItem (workbench)

Both pickers now render in the same context (new-chat-page action bar), so
the previously-needed CSS specificity overrides (icon/font sizing,
padding, color rule un-scoping in chat.css) all go away.

Changes:
- Add IPermissionPickerDelegate to permissionPicker.ts: optional
  currentLevel observable, optional isApplicable observable, setLevel.
- Refactor PermissionPicker to take a delegate. When currentLevel is
  provided, the picker label tracks it reactively. When isApplicable is
  provided, the picker hides itself when false.
- Add CopilotPermissionPickerDelegate (writes through to the active
  CopilotChatSessionsProvider session). Preserves today's behavior.
- Move AgentHostPermissionPickerDelegate to its own file under
  agentHost/, retargeted at the new interface (currentLevel,
  isApplicable, setLevel).
- agentHostSessionConfigPicker.ts now constructs PermissionPicker with
  the agent host delegate and wraps in PickerActionViewItem.
- Delete agentHostPermissionPickerActionItem.ts (the workbench widget
  subclass) and its CSS overrides.
- Revert chat.css warning/info color un-scoping (no longer needed since
  agent host doesn't use the workbench widget anymore).
- Rename the test file to match the new product file. Tests cover the
  delegate's permission-level mapping, isApplicable reactivity, and
  isWellKnownAutoApproveSchema.

* Use PermissionPickerActionItem for ChatInputSecondary, PermissionPicker for NewSessionControl

Restore the contextual split: agent host now uses each widget where it's
expected to render. The new-chat page (NewSessionControl) keeps the
sessions PermissionPicker (matches surrounding sessions pickers); the
running chat widget (ChatInputSecondary) uses the workbench
PermissionPickerActionItem (matches the rest of the chat-input
secondary toolbar that the extension-host CLI already uses).

Both share AgentHostPermissionPickerDelegate. To make the same delegate
satisfy both consumers, rename its members to
currentPermissionLevel/setPermissionLevel (matching the workbench's
IPermissionPickerDelegate).

* Consolidate duplicate AUTO_APPROVE_PROPERTY constant

Both `agentHostPermissionPickerDelegate.ts` and
`agentHostSessionConfigPicker.ts` had identical `'autoApprove'` string
constants (one called `AUTO_APPROVE_SESSION_CONFIG_PROPERTY`, the other
`AUTO_APPROVE_PROPERTY`). Standardize on the shorter name and import it
in the picker. Also drops a now-unused `KNOWN_AUTO_APPROVE_VALUES` set
that was left behind in the picker file. (Written by Copilot)

* Address Copilot review comments

- Dispose `onDidChangeProviders` Emitter in delegate test setup so the
  suite-level leak detector is happy. Refactor `setup()` to take the
  leak-tracking store and register all created disposables itself, so
  individual tests don't repeat the boilerplate.
- Fix corrupted JSDoc on `CopilotPermissionPickerDelegate` (sentence
  was mangled across an inline-code span). (Written by Copilot)

* Drop redundant `_slot` field from PermissionPicker

The `slot` local in `render()` is in scope for the `autorun` closures, so
storing it on `this` is unnecessary. Removing the field also drops the
needless null-check inside the visibility autorun. (Written by Copilot)

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, 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.
