Closes: #1971

Description

Adds a dedicated githubCopilot provider on top of the VS Code Language Model API. The existing vscode-lm provider is unchanged for models contributed by other extensions.

Problem

The generic vscode-lm provider is the only path to Copilot models today, and it has several gaps:

  • No GitHub sign-in or account state in Zoo Code, so a missing or expired session is hard to diagnose.
  • The model list is fetched once and can be empty if Copilot hasn't registered its models yet.
  • Model capabilities come from a static catalog or generic defaults, so new Copilot models report wrong or missing values until a code change ships.
  • Image parts are flattened to text placeholders.

Changes

  • Types (packages/types): new githubCopilot provider identifier and settings definition, Copilot constants (vendor, auth provider, scopes, chat extension ID), and sign-in message types. The settings schema is shared with vscode-lm (vsCodeLmModelSelector).
  • Provider (src/api/providers/github-copilot.ts): wraps the vscode-lm handler and restricts model selection to the copilot vendor.
  • Capabilities (src/api/providers/vscode-lm-capabilities.ts): derives context window, image support, and tool support from the LanguageModelChat metadata. The curated catalog is used only as a cap or fallback. Nothing is persisted to settings.
  • Images (src/api/transform/vscode-lm-image-part.ts, vscode-lm-format.ts): sends image parts as image data when the host supports LanguageModelDataPart. Minimum supported VS Code stays 1.100.
  • Extension host (webviewMessageHandler.ts, src/services/language-models/copilotModelBroadcast.ts, extension.ts): handles githubCopilotSignIn, githubCopilotReconnect, and githubCopilotManageAccount, and pushes the model list to the webview as Copilot registers models.
  • Webview: VSCodeLM.tsx adds the sign-in, reconnect, and manage-account controls plus the account label. useGitHubCopilotModels, useSelectedModel, ModelInfoView, validate.ts, and TooManyToolsWarning handle the new provider. Locale files are updated.
  • Docs: README gains a GitHub Copilot section.

Behavior notes

  • VS Code owns the GitHub session. Zoo Code does not read, display, or store the access token.
  • Sign-in establishes a GitHub identity, not a Copilot entitlement. An account without Copilot access signs in and sees an empty model list.
  • Reconnect requests a fresh authorization instead of reusing the existing session.
  • VS Code exposes no sign-out API, so Manage account opens workbench.action.manageAccounts.
  • A capability the host does not report renders as "Image support not reported" rather than defaulting to unsupported.
  • The host reports only whether a model supports tools, not how many it accepts, so no per-model tool limit is enforced. The existing too-many-tools advisory still applies.
  • Prompt caching is owned by Copilot. The public API has no cache-control directives or cache-hit usage, so the UI shows "managed by GitHub Copilot" and reports no savings.

Review focus

  • Sign-in and message flow in webviewMessageHandler.ts.
  • Capability resolution in vscode-lm-capabilities.ts and useSelectedModel.ts.
  • vscode-lm.ts and vscode-lm-format.ts, which are shared with the existing vscode-lm provider.

Test Procedure

Automated

  • Unit tests added or updated for: the Copilot provider, vscode-lm handler and format, webviewMessageHandler, Task, ProfileValidator, ModelInfoView, ProviderRouting, useSelectedModel, useGitHubCopilotModels, and TooManyToolsWarning.
  • lint and check-types pass across all packages (pre-commit hook, Node 22.23.1).

Manual

  1. Install and enable GitHub Copilot Chat.
  2. Settings → Providers → API Provider → GitHub Copilot.
  3. Click Sign in to GitHub and confirm the account label appears.
  4. Select a model and confirm the context window, image support, and caching note, then save.
  5. Run a task, and attach an image with an image-capable model.
  6. Click Reconnect GitHub and Manage GitHub account and confirm each behaves as described above.

Do not await stream.return() here.

VsCodeLmHandler.createMessage connects metadata.abortSignal to the VS Code request cancellation token, so the pending host request can settle. attemptApiRequest holds the API-work lease until the stream is consumed or closed, and retired handlers are disposed only after that lease releases.

disposeOnce() is an explicit shutdown fallback that intentionally disposes active handlers and cancels the request. Awaiting stream.return() would not prevent concurrent task disposal. The proposed wait does not address a demonstrated failure.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Added GitHub Copilot as a VS Code model provider, with sign-in, reconnect, account management, and model selection.
    • Copilot model lists refresh when available models or account status changes. Settings show context limits and reported image and tool support, or indicate when support is unknown.
    • Added setup and capability guidance in settings and documentation, translated into supported languages.
    • Requests can include images when the selected Copilot model supports them.
  • Bug Fixes
    • Copilot context-window limits now follow the selected model.
    • Provider resources are cleaned up after requests and when switching models or profiles.

This change adds GitHub Copilot as a provider with authentication, live model discovery, and host-reported capability handling. It adds image-part conversion and Copilot settings controls. It also adds API handler disposal across completion, task, export, and prompt-preview paths.

Changes: GitHub Copilot provider

Layer / File(s) Summary
Provider identity and model contracts
packages/types/src/*, src/shared/ProfileValidator.ts, webview-ui/src/utils/validate.ts, apps/cli/src/lib/utils/context-window.ts
Provider identifiers, settings, selector schemas, defaults, model metadata, and extension-host messages now include GitHub Copilot. Validation accepts Copilot selectors with an ID or family. CLI context-window lookup uses the selector ID.
VS Code model capabilities and image conversion
src/api/providers/vscode-lm.ts, src/api/providers/vscode-lm-capabilities.ts, src/api/transform/vscode-lm-*, related tests
The shared VS Code LM handler exposes overridable capability and request hooks. Capability helpers use host-reported support and token limits. Message conversion creates image parts for base64 images when supported, including images in tool results.
Copilot API handler and authentication
src/api/providers/github-copilot.ts, src/api/index.ts, src/api/providers/index.ts, related tests
API routing selects GitHubCopilotHandler for Copilot. The handler applies reported capabilities and context limits. Authentication, reconnect, account lookup, account management, and model discovery helpers are added.
Authentication messages and model broadcasts
src/core/webview/webviewMessageHandler.ts, src/services/language-models/*, src/extension.ts, related tests
The extension handles Copilot sign-in, reconnect, account management, and model requests. A debounced broadcaster refreshes models and account state when model or Copilot-session events occur.
Live model data and settings UI
webview-ui/src/components/settings/ApiOptions.tsx, webview-ui/src/components/settings/providers/VSCodeLM.tsx, webview-ui/src/components/ui/hooks/*, related tests
The settings panel supports Copilot account controls and model refresh. The webview caches model-list messages and resolves the selected model using its ID or vendor/family and host metadata.
Capability presentation and provider guidance
webview-ui/src/components/settings/ModelInfoView.tsx, webview-ui/src/i18n/locales/*/settings.json, README.md, webview-ui/playwright/*
Copilot settings distinguish unreported image and tool support and show provider-managed prompt-caching information. Localized strings, release notes, a gallery story, and visual tests are added.

API handler lifecycle

Layer / File(s) Summary
Dispose handlers after API work
src/api/dispose-api-handler.ts, src/utils/single-completion-handler.ts, src/core/task/Task.ts, src/core/config/ProviderSettingsManager.ts, src/core/webview/generateSystemPrompt.ts, related tests
One-shot completions, exports, and prompt previews dispose their handlers after use. Tasks defer disposal of replaced handlers until active requests and condensation work release their leases.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Change: Feature · Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to e6827

The GitHub Copilot provider can be merged with low risk. A few minor issues are still open: a startup warning can use a stale threshold, the context-window documentation may be inaccurate, and overlapping requests on one handler can cancel each other in a narrow edge case. Address these in a follow-up or confirm they are acceptable.

Full details: Regression Evidence

Explanation

The changed Task.ts error path calls stream.return?.(undefined) at lines 4620-4625 so the request generator can release its API-work lease after a read failure. The focused test at src/core/task/__tests__/Task.spec.ts:1974-2008 does not trigger a stream read failure and does not spy on or assert stream.return(). Its comment states that the read is abandoned, not failed by the stream. The test therefore only infers disposal and leaves the changed error path without direct focused coverage. The Playwright component snapshots for the Copilot UI are present.

Resolution

Update the real-lease Task test to wrap or spy on the request stream's return() method. Trigger a read failure after the first yielded chunk, assert that return() runs, and verify that the replaced handler remains undisposed until the request settles. Keep the existing retry and background-drain tests.

Full details: Lifecycle Resource Cleanup

Explanation

VsCodeLmHandler.createMessage creates and stores a CancellationTokenSource at src/api/providers/vscode-lm.ts:1207-1208. The source is released only in the catch block at :1445-1448; the finally block at :1474-1477 removes the abort listener but does not release the source. A successful Copilot stream, or an early return() after cancellation, therefore leaves the source attached to the handler until a later request or handler disposal. GitHubCopilotHandler newly activates this shared path for Copilot requests.

Resolution

Release requestCancellation from the createMessage finally block on success, failure, and early generator closure. Move releaseRequestCancellation(requestCancellation) out of catch and into finally so the source is cancelled, disposed, and cleared when it matches currentRequestCancellation. Add a regression test that consumes a successful stream and closes a stream early, then asserts the request source is disposed without requiring handler.dispose().

- Around line 383-407: In the GitHub Copilot branch of the model-selection
logic, cap the curated `knownModel` context window at its `maxInputTokens` so
the UI matches the extension’s enforced limit before a host report is available.
Apply the cap after spreading `knownModel` and before `reported?.modelInfo`,
preserving host-reported values when present.

…ory note

Regenerated by the pinned Playwright container in CI (webview-visual-regression artifact), per webview-ui/AGENTS.md.
…imit

When a model reports no usable input limit, the shown and enforced window is the fallback capped by the curated limit. Clarify the README and pin that the handler condenses against the same window.
Restore ClineProvider.ts to match main so the PR no longer touches provider registration, and cover the registry, superseded sign-in callbacks, unreachable broadcast targets, and unreported vision capabilities.
Copilot profiles keep the selected model in vsCodeLmModelSelector, not apiModelId, so the CLI looked up the wrong id and fell back to the default context window.
completePrompt sent no request options, so the host's consent prompt for prompt enhancement did not name Zoo Code. Add an overridable getCompletionRequestOptions hook; the generic VS Code LM provider still sends none.
A handler replaced by a profile switch was kept until task disposal when
the switch landed mid-stream, and disposed immediately when it landed
during request setup (isStreaming still false) even though that request
still held it.

Track in-flight API work instead: a request from setup through retries,
the stream, and its background usage drain, plus manual condensing.
Replaced handlers are disposed when that work settles, with task disposal
as the fallback. The main loop closes the request generator on failure so
its release runs.

Tighten completePrompt tests: abort while the stream is pending, assert
the same listener reference is added and removed, and cover the disabled
timeout and non-Error paths. Cover disposeApiHandler directly.
createMessage passed its own cancellation token to sendRequest and never
connected metadata.abortSignal to it. When a task aborted while the host
was waiting for the next chunk, the pending stream read never settled, so
the request generator could not unwind and release the API handler it
held.

Cancel the request's token when the signal aborts (or before sending if it
already has), report the resulting cancellation as one, and remove the
listener on every exit path, including an early return().
…p scope

The abort listener was added before token counting and context-window
validation, which run outside the request's try/finally. A failure there
left the listener attached to the task's signal. Attach it inside the try,
so its finally removes it on every exit path; an abort that already
happened, including one during token counting, still cancels before the
request is sent.

Rewrite the in-flight cancellation test to start the next read before
aborting, using a cancellation source that notifies its token like VS
Code's, and assert the pending read settles without being released. Cover
pre-request validation failure, an abort during token counting, and
handler disposal when the provider does not support prompt enhancement.
… state

Read each Copilot model's tool support from what VS Code reports, as Zoo-Code-Org#1971
requires. The resolver reads `capabilities.supportsToolCalling` (consumer
side) or `toolCalling` (provider side, a boolean or a tool count) into a
new optional ModelInfo.supportsToolCalling. A count only answers
"supported?" and is never surfaced as a per-model tool limit. A model the
host reports nothing about stays unset, so "not reported" is distinct from
"unsupported", and the curated catalog's flag is not borrowed. The Copilot
model details show "Supports tools", "Does not support tools", or "Tool
support not reported"; other providers are unchanged.

When token counting or a pre-send check fails, release the request's
cancellation source at once instead of leaving it for the next request.

Add a getGitHubCopilotAccount test for when no supported scope set holds a
session.
…nly as the host reports it

Connect the task's abort signal before token counting. It was attached
only after counting, so an abort while the host was still counting never
reached the count's cancellation token and createMessage could stay
pending. The request's cleanup scope now covers counting, the
context-window check, and the request. A cancelled count reads as zero,
so stop with a cancellation after counting instead of sending a request
the caller abandoned. The caller's abort is tracked on its own, because
cleanup also cancels the token and an ordinary pre-send failure must not
be reported as a cancellation.

Release only the failing request's cancellation source. A request that
fails after a newer one has started no longer cancels the newer one.

The webview took a Copilot model's tool support from the curated
catalog, which marks every family as supporting tools, so the settings
showed "Supports tools" for a model the host said nothing about. Use the
host's report alone, as for vision. Update the signed-in visual baseline,
regenerated in the pinned Playwright image CI uses, which now shows "Tool
support not reported".

Compare the whole ModelInfo in the tool-count test rather than its keys.

…y handlers

Two overlapping passive model refreshes for one view captured the same
sign-in counter, so an older refresh finishing last could overwrite the
newer model list or error. Give passive refreshes their own per-view
sequence and check it before posting either result.

The system prompt preview and provider profile export each build an API
handler only to read model metadata, and never released it. GitHub Copilot
handlers register a host configuration listener, so these accumulated.
Dispose each temporary handler in a finally block, on success, timeout, and
error. disposeApiHandler moves to its own module so callers keep cleaning up
where tests replace the api module.

Add Task tests that run the real request lifecycle: a stream the consumer
abandons is closed so its replaced handler is released, a retry keeps the
handler alive until the retry's stream settles, and the background usage
drain does too.

A manual model refresh that started before a host model-change event could
finish after the broadcast and replace its newer list with an older one:
the broadcast did not advance anything the manual refresh checks. The
broadcast now claims each view's next refresh generation, and posts only if
no sign-in or newer refresh of that view happened meanwhile, so whichever
of the two started last wins on both paths.

Use the shared disposeApiHandler in Task instead of a local copy.

Assert the delivered account and model list in the overlapping-refresh
tests instead of only counting calls.

…iew state

A broadcast claimed each view's refresh generation before its lookup
succeeded. If the lookup then failed, or a newer broadcast superseded it
and failed, nothing was posted, yet a manual refresh in flight saw its
generation taken and dropped its own reply. The webview's refresh spinner
never cleared and its buttons stayed disabled. The broadcast now records
the generation at start and claims it only when it posts to a view.

getGitHubCopilotAccount swallowed lookup failures and returned undefined,
which callers reported as githubCopilotAccount: null, clearing the account
label on a transient auth error. Let the failure throw: the broadcast logs
it and keeps each view's last known state, and a manual refresh reports it
as an error without touching the label.
