From bac4ece3a79337a55289fab0eea4507095f20e8f Mon Sep 17 00:00:00 2001 From: Hillary Mutisya <150286414+hillary-mutisya@users.noreply.github.com> Date: Sun, 25 Oct 2026 23:36:14 -0700 Subject: [PATCH 1/2] Add native decision-based commerce automation and mode selection Introduce grounded UI observation, native control and page-condition decisions, and one-use browser-bound execution. Run exhaustive control-selection batches concurrently and add verified product search/navigation WebFlows alongside the generative implementations. Expose Shopping Mode beside the independent Crossword Mode, preserve generative defaults and saved flow scope, repair main-document navigation waits, and cover the new behavior with deterministic tests and usage documentation.

The default local fixture is deterministic; the optional Seattle and Universal scenarios assert specific editions and are not general all-puzzle qualification. +## Commerce Decision pilot + +In extension **Options**, select **Shopping Mode → Generative / Decision** and +**Save Settings**. This setting is independent of **Crossword Mode**. Both +default to Generative; reset restores both, and exported settings include both. + +Shopping Mode controls the normal `searchForProduct` and +`navigateToProductPage` commands (for example, “search for coffee 12-pack” and +“open coffee 12-pack”). Decision selects the shipped native implementation +while preserving the saved command's site scope. Generative runs the existing +saved implementation. The setting is read for each command, so switching does +not require an agent restart or changing the command wording. Saved scripts +are not overwritten. Other flow names, including cart/checkout and custom +flows, are unchanged; they do not gain native Decision support. + +Two explicit saved WebFlow samples always opt into Decision regardless of the +Shopping Mode preference: + +- `decision search for coffee 12-pack` +- `decision open product coffee 12-pack` + +Start on an appropriate HTTP(S) storefront or product-results page. Enable the +browser agent's WebFlow integration, rebuild/reload the extension, and restart +the agent to register the new sample names. Existing manually saved flows are +not overwritten. The search pilot requires a native form; custom search widgets +and non-link product navigation are not supported. + +Configure the same [native Decision provider](../../config/README.md#native-decision-configuration) +used by crossword Decision mode. Azure uses the `decision_1` deployment pool +and `decision-1` deployment name; Copilot requires native Decision access. +Unavailable providers and unsupported hosts fail explicitly, without chat +fallback. + +The new WebFlow methods are `selectElement({ condition, capability, frameScope? })`, +`evaluatePageCondition(condition, frameScope?)`, and `executeUiAction(targetId, action)`. +Frame scope defaults to `"all-frames"`, requiring every frame to be accessible. +The two commerce samples explicitly use `"main-document"` for selection and +postconditions. This excludes **all** iframe content, not just presumed ads; +the native evidence and host-generated condition summary identify that scope. +These samples cannot establish embedded checkout/product-frame state. Selecting +main-document scope never falls back to all frames or silently changes scope. +Selection uses issued control IDs, visible names and product/form context, not +model-generated CSS. Execution validates the same tab, frame, document and live +node, then consumes its opaque target. Input filling and native selection +include value readback. Activation acknowledges dispatch only; each sample +requires a separate `matched` page condition before reporting success. +Page conditions classify the captured page evidence without a subsequent DOM +comparison or action-target snapshot-expiry check. Dynamic content arriving +during inference does not reject the semantic verdict. Action selection and +execution retain their existing target validation. + +This is a bounded Chrome/Edge pilot, not cart/checkout automation or general +website qualification. Inaccessible participating frames, visible open shadow DOM, oversized +evidence, stale snapshots, ambiguity, and insufficient evidence stop the flow. +Selections partition every eligible control into batches of at most 32 controls +and 24 KiB per serialized native request, with at most eight batches. Batches +run concurrently and all settle before selection returns, including on failure +or ambiguity. Multiple winners require a subsequent final comparison. An ambiguous batch +or final comparison stops selection. No controls or page text are silently +dropped, and the original 30-second snapshot lifetime is unchanged. +Closed shadow DOM, canvas/visual-only controls, Electron support, +cart-delta verification, and continuation/reasoning-tool parity are deferred. +Do not automatically retry an action whose result is uncertain. +The shared page wait rejects uncommitted navigation and retries an absent +DOMContentLoaded stability listener only while the document is loading. It +rechecks document identity and pending navigation before accepting a reply, +without waiting for unrelated iframe/ad resources to finish. +Main-document capture likewise checks pending main navigation and the content +host's document readiness, not whole-tab completion. Postconditions do not +require the dynamic page to remain unchanged throughout inference. +The four search/product-navigation samples accept optional `navigationTimeoutMs`. +Omitting it retains the existing five-second wait default. Live paired testing +uses an explicit equal 15-second budget for both variants. + +After building from `ts`, run the deterministic offline suites: + +```powershell +pnpm --filter @typeagent/browser run test:ui-decision +pnpm --filter @typeagent/browser-extension exec jest --runInBand --testPathPattern=uiDecision +``` + +Native Azure/Copilot tests use mocked HTTP with actual DOM grounding and private +frame-message handling; no live storefront, inference or purchase is involved. + ## Chat panel The extension's chat panel supports the same `@conversation` slash diff --git a/ts/packages/agents/browserExtension/src/extension/contentScript/eventHandlers.ts b/ts/packages/agents/browserExtension/src/extension/contentScript/eventHandlers.ts index a52868e27b..ccfbf6678d 100644 --- a/ts/packages/agents/browserExtension/src/extension/contentScript/eventHandlers.ts +++ b/ts/packages/agents/browserExtension/src/extension/contentScript/eventHandlers.ts @@ -74,6 +74,7 @@ function setupMessageListeners(): void { chrome.runtime?.onMessage.addListener( (message: any, sender: chrome.runtime.MessageSender, sendResponse) => { if ( + message.type === "groundedUi" || message.type === "crosswordFrameCapture" || message.type === "crosswordFrameRead" || message.type === "crosswordFrameEnter" @@ -344,7 +345,9 @@ export async function handleMessage( } case "await_page_incremental_load": { - const updated = await awaitPageIncrementalUpdates(); + const updated = await awaitPageIncrementalUpdates( + message.timeout, + ); sendResponse(updated); break; } diff --git a/ts/packages/agents/browserExtension/src/extension/contentScript/index.ts b/ts/packages/agents/browserExtension/src/extension/contentScript/index.ts index ab9733708e..2c0c6f2eeb 100644 --- a/ts/packages/agents/browserExtension/src/extension/contentScript/index.ts +++ b/ts/packages/agents/browserExtension/src/extension/contentScript/index.ts @@ -7,6 +7,7 @@ import { interceptHistory } from "./spaNavigation"; import { PDFInterceptor } from "./pdfInterceptor"; import { initializeContinuationHandler } from "./continuationHandler"; import { initializeCrosswordBridge } from "./crossword/bridge"; +import { initializeUiDecisionHost } from "./uiDecisionHost"; import "./autoIndexing"; // Initialize auto-indexing import "./autoDiscovery"; // Initialize auto-discovery of webflow actions @@ -46,6 +47,7 @@ async function injectTabIdIntoMainWorld(): Promise { // Inject tabId as early as possible (before DOMContentLoaded) injectTabIdIntoMainWorld(); initializeCrosswordBridge(); +initializeUiDecisionHost(); /** * Initializes the content script diff --git a/ts/packages/agents/browserExtension/src/extension/contentScript/uiDecisionHost.ts b/ts/packages/agents/browserExtension/src/extension/contentScript/uiDecisionHost.ts new file mode 100644 index 0000000000..bf22896046 --- /dev/null +++ b/ts/packages/agents/browserExtension/src/extension/contentScript/uiDecisionHost.ts @@ -0,0 +1,481 @@ +// Copyright (c) Microsoft Corporation. +// Licensed under the MIT License. + +import { + UI_DECISION_LIMITS as limits, + assertUiAction, + assertUiObservation, + type UiAction, + type UiActionResult, + type UiCandidate, + type UiObservation, +} from "@typeagent/browser-control-rpc/uiDecisionTypes"; + +const controls = + "a[href],button,input,textarea,select,[role=button],[role=link],[role=checkbox],[role=radio],[role=combobox]"; +const excluded = + "script,style,noscript,template,input,textarea,select,[hidden],[aria-hidden=true],[inert]"; +const normalize = (text: string) => text.replace(/\s+/g, " ").trim(); + +function visible(node: Element): boolean { + if (!node.isConnected || !node.getClientRects().length) return false; + for ( + let current: Element | null = node; + current; + current = current.parentElement + ) { + const style = getComputedStyle(current); + if ( + current.matches("[hidden],[aria-hidden=true],[inert]") || + style.display === "none" || + style.visibility === "hidden" || + style.visibility === "collapse" || + style.opacity === "0" + ) + return false; + } + return true; +} + +function visibleText( + root: Element, + isVisible: (node: Element) => boolean, + cache: Map, +): string { + const cached = cache.get(root); + if (cached !== undefined) return cached; + if (root.matches(excluded) || !isVisible(root)) { + cache.set(root, ""); + return ""; + } + const text = normalize( + Array.from(root.childNodes) + .map((child) => + child.nodeType === Node.TEXT_NODE + ?
