From 730ecfb5aef40ed821b2c2ade3e9aaa061cba3d7 Mon Sep 17 00:00:00 2001 From: ulugbekna Date: Sat, 12 Sep 2026 00:08:29 +0200 Subject: [PATCH 1/6] canvases: feat: add local canvases to the Agents Window Add the default-off local canvas preview across Agent Host, the canonical protocol adapter, Sessions presentation, package authoring and native browser surfaces. Preserve exact workspace/revision authority, external document data, canvas-first retention, live source ownership and request-frozen context. Project genuine joined-SDK requests into chat turns so canvas-originated requests use visible tool approvals and cancellation. Include regression coverage, runnable fixtures, launch tooling and the required JavaScript allowlist entries for source packages that run without transpilation.

Windows, Linux and macOS x64 are not yet qualified. The host + ignores development SDK selection on these platforms, even when all three + artifact variables and the preview setting are supplied. The preparer refuses + before creating a profile. Ordinary VS Code and the separate PoC are unchanged; + inert package preparation/review does not establish execution support. +- A built public Node SDK exporting `ExtensionLaunchProvider` and + `session.rpc.retain()`. Its `start()` must validate the live runtime + `registerExtensionLaunchProvider` acknowledgement as `contractVersion === 1`. +- The matching **Node CLI** entry, not a standalone runtime embedding without a + default Node bootstrap profile. + +These SDK/runtime changes are **unreleased**. A working local checkout or npm +tarball is not evidence of registry availability. Release requires the SDK's +public launch option, v1 negotiation, generated retention API and event, and the +matching runtime implementation to ship together. No registry version is assumed. + +Before widening the platform gate, qualify each native platform/architecture +with the real public SDK/runtime: prepare/review/exact-workspace consent, +canvas-first retention and delayed draft transfer, user/action shared data, +context/removal, native origin/frame/popup/download/clipboard policy, source +close/restart/cold restore, themes/focus/accessibility, and preview/AI-disable +recovery. In particular, test user-gesture same-origin new-tab and popup denial, +not just script popups. Record native evidence and process/profile cleanup. +Source tests alone do not qualify a platform. There is no bypass setting. +Real screen-reader qualification and publication/rollout approval remain +separate external gates; no package publication is authorized by this preview. + +## Prepare and launch + +Run from this VS Code worktree: + +```sh +node scripts/prepare-local-canvas-sdk.mts \ + --sdk-entry file:///absolute/path/to/sdk/nodejs/dist/index.js \ + --runtime-cli /absolute/path/to/runtime/dist-cli/index.js \ + --workspace /absolute/path/to/an/ordinary/workspace \ + --root .c0 +``` + +The command checks the bridge against **both SDK declaration sets**, using the +existing TypeScript compiler and all VS Code ambient declarations. It builds +only `canvas-sdk-bridge.mjs`, then writes `canvas-sdk-launch.json` under the +chosen root. Nothing is installed or changed in `node_modules`. + +Add `--launch` to start the prepared development build. The root contains isolated +user-data, extensions, shared-data, agent-plugin and Copilot directories. No +system temporary directory is used. Short directory names preserve enough space +for native Unix sockets even in this deep worktree; overlong roots are rejected +rather than falling back outside it. `.gitignore` excludes the private root's +contents. Use different short roots for concurrent instances. +Electron keeps the caller's real `HOME`/`USERPROFILE` so the main/UI processes +can use the operating system Keychain normally. The generated bridge applies +its isolated home only through the public SDK child-process `env` option; +`runtimeEnvironment` in the manifest records those overrides. The Agent Host +retains the private Copilot, plugin, profile, and temporary paths. No mock +Keychain or workspace-trust bypass is enabled. +`--cdp-port` and `--agent-host-port` accept +available ports for a browser/debugging worker. CDP defaults to port `0` for +automatic allocation; read `cdpEndpointFile` from the manifest after launching. + +For authentication, optionally pass `--source-user-data-dir /path/to/closed-profile`. +Only the authentication-bearing profile files are copied, not settings, plugins, +MCP configuration or Agent Host data. A nonempty SQLite WAL is rejected; close +and checkpoint that profile first. The source profile is never modified. + +The preview setting is enabled in the isolated profile. Its effective +preview/AI-disable decision reaches the **first** native initialization handshake, +before runtime capability negotiation, so no initial message or extra window +reload is needed. Use the canvas package manager to prepare a package, inspect +its revision and approve it for the selected workspace. Then explicitly open +its declared canvas. Browsing and history restoration do not execute it. + +New canvases opened by an agent in the active chat are revealed once their +endpoint is ready, without focusing the page. If navigation changes while the +endpoint is loading, or the owning chat is in the background, use the canvas +notification or **Canvases > Reveal Canvas**. Restored instances, provider +recovery and refreshes do not reopen a tab you hid. Explicit **Open Canvas** and +**Reveal Canvas** commands still focus their result. + +Canvas backends may submit a request through their joined public SDK session. +The Copilot adapter projects the actual root user-message event into the owning +chat before tool progress and permission requests arrive; it does not resend +the prompt or approve tools. These requests appear in chat and use the normal +approval and cancellation controls. Synthetic skill/subagent messages remain +separate, and normal host-sent echoes keep their existing turn identity. + +Canvas UI and execution honor the **global** preview and `chat.disableAIFeatures` +values, including when the Agents Window has a different workspace-level AI +setting. Disabling either gate stops owned canvas backings, not saved documents. +When switching between the development and bundled SDK paths, use **Developer: +Restart Local Agent Host**, reopen the retained chat, and explicitly restart its +canvas provider if its catalog is dormant. No preparatory message is required. +Canvas-first startup retains an extension-free backing, waits for its disconnect +reply, then resumes the same SDK session with extensions enabled. Later turns +that need a new tool/plugin configuration use the same completion boundary. +An early shutdown event is not proof that teardown finished; a rejected +disconnect aborts the handoff rather than enabling extensions or sending the +next turn. Ordinary shutdown notification handling is unchanged. + +Package removal unregisters the package and revokes its grants. Inert cached +snapshots and saved document data remain; removal is not a secure-erasure operation. + +### Known development-runtime limitation + +Approving a package after a chat has completed a turn can fail on the next +same-session resume with `Hook processor is not configured`. This was reproduced +using only the public SDK: an awaited model change followed by disconnect and +same-ID resume can race runtime hook initialization. The integration regression +for this sequence remains failing with the current development artifacts. + +For the validated initial workflow, approve the package before creating a new +chat. This avoids the affected sequence; it is not a repair for an existing +conversation. The host does not silently skip model changes, retry an +indeterminate operation or replace the conversation to hide the error. An +upstream lifecycle fix and requalification are required before this limitation +can be removed. + +The environment selects three matching artifacts: + +- `VSCODE_LOCAL_CANVAS_SDK_ENTRY`: the public SDK ESM file URL. +- `VSCODE_LOCAL_CANVAS_SDK_BRIDGE`: the bridge compiled for exactly that SDK entry. +- `VSCODE_LOCAL_CANVAS_RUNTIME_CLI`: the runtime Node CLI path. + +The host ignores this route in built and non-desktop hosts. With preview off it +uses the unchanged bundled SDK path. With preview on but no development artifacts +it cannot advertise normal canvas execution. Partial configuration, a different +SDK bridge, or failed v1 startup rejects the development path without retrying +without a launch provider. Unset `VSCODE_LOCAL_CANVAS_POC_ROOT` for this route; +the PoC retains its separate launcher and behavior. + +## Contract and scope + +The bridge uses only public SDK operations and structural host interfaces. +SDK-owned instances such as tool sets, canvas objects and request handlers do not +cross SDK module copies. The development adapter projects newer event/task DTOs +onto the bundled host's supported surface; newer-only diagnostic events, SDK +skills and client-task variants are not surfaced. Runtime permission enforcement +and managed settings are still authoritative and are never reimplemented here. +Typed event subscriptions retain the SDK's event-type index, so streamed deltas +do not pass through unrelated handlers. Unsubscribing immediately detaches the +backing SDK listener. Bridge preparation typechecks both public SDK declaration +sets and runs `scripts/local-canvas-sdk-bridge.test.mts` with the existing Mocha +runner, covering streaming delivery, permission diagnostics and teardown. + +Every launch needs the exact chat/backing lease, current snapshot fingerprint, +exact-workspace or shared-local-host approval and effective customization +enablement. Both grant scopes span profiles sharing the Agent Host and its +user-data directory; approval is not profile-isolated. Exact-workspace approval +is the default. Existing grants for the same revision accumulate, so narrowing +an existing host-wide grant requires explicit revocation first. The lease +remains closed until public SDK retention completes. The resolver preserves the +approved runtime `defaultLaunch`, adding only `VSCODE_CANVAS_DATA_DIR`. Mutable +documents remain outside installed code. Revocation stops owned backings. +Unreadable or invalid saved package approvals make package management and +execution unavailable without preventing ordinary host/provider construction. +The saved records are preserved for recovery; the service does not replace +them with an empty registry or allow management to overwrite them. + +Canvas-first creation uses an extension-free backing, retains it without a turn, +disconnects, then resumes **the same SDK ID** with the full configuration and +extensions enabled. Cold history reads stay extension-free; explicit open, +restart or a genuine turn admits canvas initialization. Cold reopening can call +the extension's open handler again; this is not exactly-once execution. + +The offline integration test is +`src/vs/platform/agentHost/test/node/providerIntegration/copilotCanvasSdk.integrationTest.ts`. +It runs the real host graph, AHP adapter, public SDK and runtime in Node through +the existing integration runner. Disk I/O is real; file watching is excluded from +this fixture. It uses a local mock-model response only after proving no-turn +retention and cold restoration. Native UI and Windows/Linux qualification remain +separate. The live test also verifies a failed first open, unknown runtime +backings, refusal of the bundled SDK as a development bridge, rejection of an +older runtime acknowledgement, and an ordinary mock-model turn through the +unchanged bundled SDK after disabling preview. diff --git a/scripts/prepare-local-canvas-poc.mts b/scripts/prepare-local-canvas-poc.mts new file mode 100644 index 00000000000000..fa10ff0f28d4bc --- /dev/null +++ b/scripts/prepare-local-canvas-poc.mts @@ -0,0 +1,103 @@ +/*--------------------------------------------------------------------------------------------- + * Copyright (c) Microsoft Corporation.

The [integration suite](../../copilotCanvases.integrationTest.ts) +copies it into a temporary Copilot home and runs only that explicitly created code. +It never uses a model, personal credentials, or installed user extensions. + +The same original fixture is used by the +[isolated Agents Window PoC launcher](../../../../../../../../../scripts/local-canvas-poc.md). +That interactive developer flow can use a real Copilot conversation; the SDK +regression suites described here still run without model calls. The page displays +separate button-click and declared-action counts so each path can be verified. + +The fixture joins the owning session with `createCanvas`/`joinSession`, starts one +loopback HTTP server, and declares a `counter` canvas with an `increment` action. +The HTML button uses HTTP; document snapshots arrive over SSE. Multiple instance +IDs share data through the open input's stable `documentId`. A process-generation +nonce makes restarted endpoints distinct even if the OS reuses a port. + +`documents/.json` holds the document. `audit.jsonl` records actual +provider callbacks, the raw `action.result` before returning to the SDK, and +process cleanup. Its fixture-owned `started` marker is +written before `joinSession`, independently of tool or canvas advertisement. +Tests count those markers across create, enable/disable, reload and cold resume, +and verify that both enable and disable decisions persist. A separate safe copy +demonstrates that disabling one known ID does not prevent a newly discovered +backend from starting, even with no tools advertised. + +Explicit canvas close releases its SSE subscriptions without deleting the document +or stopping other instances' server. +Process shutdown closes the server and transport. A joining extension must not +call `session.disconnect()` to leave: that API destroys the shared session, which +belongs to the owning SDK client. + +## Running the proof + +From the repository root, generate current output once: + +```sh +npm run transpile-client +``` + +Use the repository integration runner when Electron test assets are available: + +```sh +./scripts/test-integration.sh --run src/vs/platform/agentHost/test/node/providerIntegration/copilotCanvases.integrationTest.ts +``` + +The same node-only suite also runs with the existing Node Mocha entrypoint, without +downloading Electron: + +```sh +npm run test-node -- --run src/vs/platform/agentHost/test/node/providerIntegration/copilotCanvases.integrationTest.ts +``` + +The suite rejects any outbound model request. It gives each provider process a +temporary `HOME`, `COPILOT_HOME`, working directory and configuration directory, +checks fixture shutdown markers, stops the SDK-owned runtime, and removes the +temporary home. Do not install this fixture into a personal Copilot home. + +### Comparing the actual VS Code client mode + +The separate [startup boundary suite](../../copilotCanvasStartupModes.integrationTest.ts) +uses the same platform CLI `index.js` entrypoint selected by `CopilotAgent`, with +`mode` genuinely omitted or explicitly `empty`. Its entrypoint matrix also +includes `@github/copilot/npm-loader.js` in empty mode, strictly as an isolated +compatibility case, not a proposed production launch change. Both use stdio, but +are distinct host entrypoints. The matrix prints each exact path, mode and +extension/renderer options. It does not override the CLI's bundled extension SDK. + +This opt-in macOS proof must run inside an OS sandbox that blocks all outbound +network access except loopback. The environment flag only opts into the tests; +it is not an enforcement mechanism. Do not set it without the sandbox wrapper. + +```sh +env VSCODE_CANVAS_MODE_PROBE_NETWORK_ISOLATED=1 \ + /usr/bin/sandbox-exec \ + -p '(version 1) (allow default) (deny network-outbound) (allow network-outbound (remote ip "localhost:*"))' \ + node node_modules/mocha/bin/mocha.js test/unit/node/index.js \ + --delay --ui=tdd --timeout=5000 --exit \ + --run src/vs/platform/agentHost/test/node/providerIntegration/copilotCanvasStartupModes.integrationTest.ts +``` + +This is the existing Node test runner, without npm user configuration or an +Electron download. The provider has an isolated home, OS keychain access disabled, +no credentials, a non-serving loopback BYOK placeholder, and rejecting model and +approval handlers. Configuration discovery and file hooks are enabled as in the +production launcher, but only the original fixture is present in the isolated +directories. Remote sessions, MCP connections and telemetry are disabled for the +comparison. It does not qualify authenticated production bootstrap or other OSes. + +Both modes load the fixture on the production entrypoint when extensions are +requested; neither loads it when extensions are off. A PID-bearing startup marker +appears before introspection, with no approval callback. Renderer off/on changes +the canvas tool list, not whether that backend starts. + +The selective-start test deliberately separates three fixture identities. A +bootstrap copy creates retained history through real open/action/open/close RPCs +and is stopped before the measured phases. The subject and a control copy are +installed disabled before their first possible start. Subject markers stay at +zero through a new session's create/reload and a cold resume/reload of the saved +session. Explicit enable starts only the subject; the control never starts and +the bootstrap never restarts. The later subject disable is recorded separately +as one start followed by one stop, not mistaken for pre-start prevention. + +New-discovery cases use the production entrypoint with mode omitted. A new safe +copy starts without an explicit enable or approval on both reload and cold +resume, even while no tools are advertised. Inert discovery metadata is recorded +separately from these execution markers. Thus the tested public configuration +does not provide the required default-deny startup authorization. + +The suite separately asserts the fixture's raw action result and the SDK RPC +envelope `{ result: }`. Callback fields are compared without +inventing `host`; event projections remove only IDs, parent IDs and timestamps, +preserving all other optional fields. No `reopen` intent is inferred from an +`opened` event. + +## Adapter invariants from the measured contract + +- `recorded` and `removed` determine durable logical instance identity when the + session history is retained. Presentation and provider availability are separate. +- `unavailable` must immediately retire the current endpoint reference without + declaring the logical instance closed. +- Empty live `listOpen` is not evidence of logical closure: unavailable instances + are omitted. The SDK's cached `openCanvases` can retain a stale URL and is not + evidence of a valid endpoint. +- Reconcile durable records, live lifecycle events, and the current snapshots + according to those semantics. Never invent an endpoint lease from a URL or + navigate from a stale cache. The fixture URL's generation nonce only makes + process restarts observable; it is not a production authorization mechanism. +- Runtime Read/Edit/Shell permissions do not sandbox arbitrary extension Node + code or direct canvas actions. Management-tool exclusion controls the surface, + not startup or execution authorization; a VS Code-side matcher cannot replace + the required runtime enforcement. + +## Scope of the decisions and the release blocker + +The tested IDs are user-scope extensions in one isolated `COPILOT_HOME`. +Enablement persists beyond the initiating chat and SDK process: +`session.extensions.enable` is not a one-chat execution grant. These tests do not +establish transactional isolation for concurrent chats or a content-bound approval. +All preference mutations target explicitly named fixtures in throwaway servers. +Do not turn this setup into a production disable-everything/reenable-around-create +sequence; shared server state and concurrent chats make that unsafe. + +Pre-disable is therefore not a sufficient production trust boundary. It prevents +the known disabled candidate from starting, but new discoveries remain +default-enabled and are observed starting on reload and resume. No VS Code-side +policy matcher, blanket approval shim or manual process launcher is supplied. +General arbitrary-extension startup remains out of scope pending an agreed +authorization model. The explicit local developer PoC can run this reviewed +fixture in its isolated home without claiming that stronger boundary. Normal +sessions retain disabled runtime-extension startup. + +No-turn retention and canvas restoration are separate assertions. The minimal +named single-open and unnamed histories in the compatibility empty-mode tests +are not retained at shutdown; there is no valid cold canvas restore to claim for +those histories. The successful restore tests use history actually retained by +the runtime after public named open/action/open/close operations. They neither +fabricate event logs nor replay actions to manufacture success. No model call +or local mock model is needed for that separate retained-history proof, and it +does not imply that arbitrary no-turn sessions will persist. + +## Pinned compatibility and intentional limitation tests + +The initial proof targets SDK `1.0.13-preview.4` and CLI `1.0.83-2`. Revisit the +documented limitation assertions when updating those dependencies: + +- The SDK's default standalone wrapper rejects extension startup without a + registered extension launch provider. This is not the path currently used by + `CopilotAgent`: the production code explicitly selects the platform CLI's + `index.js` and omits `mode`. The mode comparison verifies fixture loading on + that path in both omitted and empty modes. Do not attribute the standalone + wrapper's error to the deployed VS Code entrypoint. +- `requestExtensions: true` auto-starts discovered, default-enabled extensions. + Inert discovery and per-ID disable are available, but neither is a default-deny, + content-bound execution grant. Session enable also updates persistent enablement. +- `requestCanvasRenderer` gates model tools, not direct canvas RPC authorization. + Excluding `extensions_manage` and `extensions_reload` removes management tools. + Managed read/edit/shell permissions do not sandbox an extension's Node backend. +- Live `opened`, `closed`, `registry_changed` and `unavailable` events are separate + from durable `recorded`/`removed` events. There is no `reopen` or availability + discriminator in an `opened` payload. +- Repeated open calls the provider again. Changing its input updates live state + but does not replace the first durable open record. Do not use open as a generic + replay-safe focus operation or change a document's identity through repeated open. +- An unavailable provider disappears from `canvas.listOpen()`, while the SDK's + `session.openCanvases` cache retains its old URL until reconnect. Neither snapshot + is a complete availability model; consume lifecycle events and invalidate endpoints. +- The cold-resume proof uses a named open/action/open/close workflow recorded by + the runtime, not a synthesized transcript or a supplied journal. It restores + without an LLM, recovers a fresh endpoint, and does not repeat actions or revive + closed instances. Naming alone is not sufficient: named single-open canvases + can lose their history on shutdown even with explicit workspace persistence. + Unnamed canvas-only sessions are also not retained in the tested scenario. +- A throwing `onClose` does not reject the caller's close. Provider disconnect, + reload and runtime shutdown do not replace per-process cleanup with `onClose`. + +These tests are not approval to enable production extensions. Selective trusted +startup remains a shipping requirement. A public SDK launch-provider integration +would additionally be required if switching to the standalone wrapper; that +separate gap does not prevent loading on the existing VS Code entrypoint. +The tests do not qualify Integrated Browser rendering or any +remote, web/mobile, sharing, office, native canvas, or other-provider parity. diff --git a/src/vs/platform/agentHost/test/node/providerIntegration/fixtures/localCanvas/client.js b/src/vs/platform/agentHost/test/node/providerIntegration/fixtures/localCanvas/client.js new file mode 100644 index 00000000000000..4d9eae51a83529 --- /dev/null +++ b/src/vs/platform/agentHost/test/node/providerIntegration/fixtures/localCanvas/client.js @@ -0,0 +1,33 @@ +/*--------------------------------------------------------------------------------------------- + * Copyright (c) Microsoft Corporation.
