agent host: refactor: adopt experimental AHP canvas channels by ulugbekna · Pull Request #337780 · microsoft/vscode

Ulugbek Abdullaev (ulugbekna) · 2026-09-24T18:53:53Z

Summary

Migrates the local Copilot canvas support already on main from its temporary VS Code-specific transport to the experimental canvas channel merged in microsoft/agent-host-protocol#472.

keeps stable chat state limited to minimal canvas resource references
publishes full live presentation state, including the optional HTTP(S) source, on independently subscribable ahp-canvas: channels
removes the private vscode/canvases/v1 notification, source-resolution request, initialize capability, and parallel snapshot model
preserves the existing chat.agentHost.canvases.enabled runtime/presentation gate and durable local-Copilot-only product policy
keeps shared Sessions state provider-neutral

The synced AHP source is pinned to the merged PR commit 6eec1b91.

Host projection and lifecycle

A true canvas-open event creates a new lifetime-scoped ahp-canvas: resource. Metadata or source changes retain that resource and emit canvas/stateChanged; provider unavailability clears the source through full-state replacement. Closing the canvas removes chat membership and prunes the channel. Session/chat teardown also clears owned channels.

Canvas subscriptions are live-only. They return existing host state, pin the owning session through the normal subscription residency path, and never restore a provider or replay an open/action request. The existing eight-canvas bound and restart non-restoration behavior remain unchanged.

Client and Sessions adaptation

The protocol client uses the standard subscription manager and canonical canvas reducer, preserving exact host-advertised resource URIs rather than reconstructing remote identities.

The Agent Host Sessions provider follows each advertised canvas reference with a cached resource-scoped subscription and projects immutable provider-neutral state. Unknown membership is distinct from an authoritative empty collection, and pending/error channel state retains membership without a live source.

Presentation support remains a local provider decision: durable local Copilot sessions expose supportsCanvases; remote, Claude, and Codex sessions do not. The existing setting and AI entitlement still control actual runtime enablement and editor presentation.

Privacy and stale-load protection

Canvas URLs are redacted from AHP action, snapshot, initialize/reconnect, and replay diagnostics without mutating live state. Sources remain HTTP(S)-only. The editor keeps local input, source, owner, and load-sequence checks and disposes superseded BrowserViews. Metadata/source changes do not reopen a user-dismissed canvas.

Removed temporary surfaces

AgentCanvasAvailability, IAgentCanvas, and IAgentCanvasSnapshot
IAgentHostCanvases and IAgentService.onDidChangeCanvases
vscode/canvases/v1/changed and vscode/canvases/v1/resolveSource
the VS Code-specific canvas initialize capability and metadata helpers
revision-fenced source resolution

A separate AHP agent capability is intentionally absent: clients cannot initiate canvas operations in this scope, and server-published chat references are sufficient discovery. A capability can be introduced later alongside client-originated open/action operations if needed.

Strict no-click automatic canvas reveal verification

After the prompt is submitted, the model calls open_canvas; Chess — e2e becomes the selected visible editor and renders the board without any tab, editor, focus, or browser click.

Native Chess canvas recording

The earlier workbench recording captures only the Electron renderer and omits the OS-composited WebContentsView. This recording targets the native canvas surface directly, so the board UI is visible.

Commit-by-commit reviewer guide

The history remains four signed semantic commits. Follow-up fixes and canvas-originated chat visibility are folded into the feature commits that own their behavior.

Context

The released Copilot runtime already supports extension-provided canvases and the native model tools list_canvas_capabilities, open_canvas, and invoke_canvas_action. This PR adds the missing VS Code path:

load the extension during normal trusted create/resume;
project a model-opened instance as safe chat-owned metadata;
resolve its private HTTP(S) source on demand;
show it automatically beside the owning chat in a private native page.
project model work started by the canvas extension as a normal visible turn in that chat.

1. `bf86d9ae016` — reusable native page host

Subject: browser: refactor: extract reusable web contents host

This is a behavior-preserving BrowserView refactor. It extracts the native overlay, layout, focus, screenshot, keybinding, and disposal logic into WebContentsViewHost.

Why needed: the canvas editor needs the proven native WebContentsView host without duplicating Electron lifecycle code or opening the normal browser editor/navigation UI.

Review focus: confirm that regular integrated-browser behavior and disposable ownership remain unchanged.

2. `26e93915e68` — trusted runtime lifecycle, AHP projection, and visible provider turns

Subject: agent host: feat: launch and project Copilot canvases

This commit:

enables released SDK extensions/canvas rendering during normal durable create/resume;
resolves the paired runtime/SDK/bootstrap assets;
admits canonical project extension entrypoints only beneath live session roots;
rejects symlink escapes and session-scoped launches;
supplies stable VSCODE_CANVAS_DATA_DIR values;
waits for extension readiness before the relevant model turn;
syncs chat: feat: add canvas projection agent-host-protocol#472;
projects revisioned metadata while retaining source URLs privately;
resolves only the exact live chat/instance/revision and only HTTP(S);
redacts source responses from logs;
suppresses duplicates, caps each chat at eight instances, and drops restart replay;
projects correlated canvas-extension session.send() requests as provider-started turns in the owning chat;
routes their tools, approvals, usage, responses, errors, cancellation, and completion through normal AHP state;
excludes extension-authored prompts from human-message telemetry;
includes the tokenless bundled-runtime proof and deterministic prompt snapshots.

The former protocol/prompt CI follow-up is folded here. It restores MCP blocking state when the synced AHP optimistic background request is rejected, and it prevents ambient Copilot app feature flags from contaminating prompt baselines.

Why needed: this is the complete host-side correctness and privacy boundary. Without it, the model can open a runtime canvas but VS Code has no safe live state to present; likewise, a canvas can start real model work while the owning chat remains silent.

Expected interaction semantics:

A local canvas-only mutation, such as moving a chess piece, does not create a chat turn by itself.
If that action causes the extension to call session.send()—manual Agent move or automatic replies—the generated request, tools, approvals, usage, response, errors, cancellation, and completion appear in the owning chat.
A visible provider-started turn requires a root SDK message with both public messageId and turnId. Subagent, injected-context, steering-owned, and uncorrelated events do not create turns.

Review focus: extension path admission, readiness races, revision fencing, URL privacy/redaction, provider-started turn correlation, telemetry attribution, restart semantics, and resource limits.

3. `3829af42c26` — private unlisted BrowserViews

Subject: browser: feat: add private unlisted browser views

This commit adds explicit Listed / Unlisted presentation state and an external-view creation API.

Canvas pages are user-owned, ephemeral, unlisted, and have no agent audience or associated browser resource. They are excluded from browser hydration, discovery, quick open, and tools. Popup creation is denied. The renderer subscribes before initial navigation so it cannot miss the first URL update.

It also adds incremental bounded Chromium AX retrieval: 2,000 nodes and 32 KiB formatted text.

Why needed: embedding the page as an ordinary browser tab would leak ownership into browser discovery, persistence, and automation surfaces.

Review focus: listed/unlisted propagation, discovery isolation, popup policy, navigation ordering, and accessibility bounds.

4. `99270b119c9` — Agents-window presentation

Subject: sessions: feat: present Copilot canvases beside chats

This commit adds provider-neutral ISessionCanvas contracts, local-Agent-Host-only capability adaptation, and the default-off sessions.experimental.canvases.enabled rollout setting.

SessionCanvasService automatically reveals a ready new revision beside its active owning chat. A user-closed revision stays dismissed until the model opens a newer revision. Canvas/provider/session removal and setting disablement clean up presentation state.

SessionCanvasEditor resolves the source on demand, mounts an unlisted external BrowserView, manages focus/layout/visibility, and is intentionally non-serializable. Accessibility Help, Accessible View, and verbosity configuration are included.

The former final-rebase fix is folded here: the adapter preserves the latest shared model-selection and dynamic default-chat behavior from main.

Why needed: commits 2 and 3 make the canvas observable and safe to embed; this commit is the minimal user-visible Agents-window vertical slice.

Review focus: active-chat ownership, automatic reveal, dismissal-by-revision, disposal paths, default-off gating, local-only provider scope, and accessibility.

Suggested review order

Commit 1 for the mechanical extraction.
Commit 3 for the isolated BrowserView privacy primitive.
Commit 2 for runtime trust, AHP ownership, and proof.
Commit 4 for the final Sessions UX.

Validation status

released pair: @github/copilot-sdk 1.0.15-preview.3, runtime 1.0.89-3
full client typecheck
full CopilotAgentSession suite: 712 passing
deterministic Copilot prompt replay: 23 passing
bundled-runtime integration covering extension-before-turn ordering, model-opened canvas, and extension-started visible chat turn: 1 passing
focused Sessions and BrowserView privacy/accessibility suites
post-rebase focused unit slice: 2,206 passing, 12 pending
GitHub's full matrix is rerunning after the rebased head was force-pushed

Highest-value questions

Is canonical project-extension admission strict enough around path and shutdown races?
Is metadata-only AHP state plus revision-fenced source resolution the correct privacy boundary?
Does the provider-started turn bridge admit only correlated live root requests and preserve normal approvals/cancellation?
Can an unlisted BrowserView enter any normal browser discovery or automation path?
Is automatic reveal scoped tightly enough to the active owning chat and current revision?
Are the eight-canvas and accessibility limits appropriate initial production bounds?

The PR description contains the full architecture, validation matrix, Chess screenshot, and OS-composited verification video.

Definitive OS-composited verification: Agents window + native Chess canvas

This window-level recording captures both the Electron renderer and the native WebContentsView in the same frame. After Enter, there are no tab, editor, focus, or browser actions: the model calls open_canvas, and the Chess canvas automatically appears beside its owning chat.
