Select an element on the live page, then add other elements, regions, drawings, a comment, or per-element style changes.

Available React development-source information is included when the page exposes it; annotation also works on non-React pages. + +**Add to chat** or **⌘Enter** appends the annotation to the existing draft. The context includes the URL, text, selectors, bounds, available source metadata, and the user's comment. A marked screenshot crop accompanies it when the current model supports images and attachment limits permit. Text context remains available for text-only models or capture failure. Page-derived content is labeled untrusted evidence. Nothing is sent until the user sends the draft. If the current composer is unavailable (for example during a questionnaire), the editor keeps the annotation for retry. + +## Aiden tools and lifecycle + +An eligible foreground desktop workspace agent initially receives only `browser`, a discovery tool. Calling it installs fourteen executable tools at the next model-turn boundary: `browser_status`, `browser_open`, `browser_navigate`, `browser_resize`, `browser_set_appearance`, `browser_snapshot`, `browser_click`, `browser_type`, `browser_press`, `browser_scroll`, `browser_evaluate`, `browser_wait_for`, `browser_recording_start`, and `browser_recording_stop`. The gateway returns their names and usage guidance; it does not duplicate their schemas in the transcript. + +The initial added static context is **85 estimated tokens** (337 serialized characters), versus the original 2,679. Once activated, the gateway, fourteen schemas and browser guidance add **3,032 estimated tokens**, including the new local-file arguments. These numbers use Aiden's `estimateStaticContextTokens` characters/4 heuristic, not a provider tokenizer or billing measurement. Unrelated responses pay only the gateway cost. Effective disabled access removes even the gateway on the next generation. Host exclusions are respected before discovery. + +Discovery state lasts for the current generation, including compaction and emergency continuation. A new generation starts with the gateway again. Pi receives the actual executable tool registry through its next-turn context update; the outbound transform and durable compaction estimator use the updated registry and prompt. Compaction summarizes conversation history and retains recent call/result pairs; it does not remove active tool schemas or close browser tabs. Outgoing context keeps the newest three image-bearing browser snapshots, independently of Computer Use's three-image pool. Older screenshots remain in the private journal, with text and error semantics preserved. Model-facing snapshot text is capped at 32,000 serialized characters, with intact selected locators, failure-prioritized diagnostics and explicit omission counts. Text-only models receive no screenshots. + +These tools operate on the user's workspace tabs. Browser access authorizes navigation and page inspection in the selected profile, including background tabs when `open=false` or automatic reveal is disabled. Ask mode gates interaction/evaluation; it does not add a prompt for every navigation or read. Background tabs remain listed in Environment → Browser, and their calls remain visible in chat activity. Calls bind to the generation and workspace, serialize against the selected tab, and revalidate permissions and cancellation. Ask-mode interaction/evaluation approvals bind to the exact tab, page revision and arguments; navigation or human takeover invalidates them. A failed action invalidates actions already waiting in the same generation's queue. Later recovery can inspect a fresh snapshot. Keyboard expectations require the native Chromium debugger-source flag exposed by the pinned Electron build, plus matching keys/modifiers. Physical keyboard input, including identical or repeated keys, interrupts immediately; missing keyboard source flags fail closed. Electron omits that flag from mouse-down/up events, so a matching physical mouse event can consume a pending same-button expectation; a subsequent unmatched event interrupts. Mouse expectations are bounded and removed when dispatch settles. Electron upgrades must preserve the keyboard event contract or keyboard automation will stop safely. The private Assistant, Bots, headless generations and read-only subagents do not receive these desktop-only tools. + +`browser_open` and `browser_navigate` accept a local HTML/PDF `path` (or a local file URL) through the managed preview service. Every preview serves only its entry document and a finite declared asset set, with a separate origin for each distinct grant. Agent opens require explicit `assetPaths`. Undeclared sibling files are blocked, including inside the workspace. Workspace entries and declared workspace assets use existing workspace authority. Direct user file opens discover static HTML, CSS and JavaScript-module dependencies inside the owning workspace, including relative and workspace-root-relative asset paths, without executing page code. Discovery is limited to 64 files, eight dependency levels, 1 MiB per parsed source and 4 MiB total parsed source. It never grants directory access or follows computed imports, dynamic fetches, external URLs, or unrelated documents. Literal module imports, including literal dynamic imports, remain statically discoverable. Parsed sources are pinned by identity, content, size and modification time. Reopen the document after editing or touching a parsed source, including a same-content save, so Aiden can rebuild the asset grant; existing previews deliberately fail closed with 409. Missing or out-of-scope references found during discovery remain blocked and appear in browser diagnostics. Discovery does not resolve import maps, `new URL(..., import.meta.url)` worker/asset references or scripts injected at runtime; those unrecognized patterns do not produce a discovery warning. Pages that need them should run through their own development server, or use explicit `assetPaths` for supported ordinary asset requests. Worker requests do not receive implicit preview authorization. Explicit `assetPaths` bypass discovery and retain the exact supplied set. An outside-workspace document requires explicit approval for that exact file and any declared `assetPaths`, including in Full access mode. The grant is a main-only object with pinned file identities; model-supplied flags cannot authorize access. All local files are served individually, with no directory listing or mount of all `/tmp`. + +Managed previews bind to loopback on an OS-assigned port and use capability protection. Initial navigation uses a bootstrap token; subsequent declared-file requests use a main-injected header restricted to the owned workspace, exact destination origin, and committed requesting-frame origin. Preview cookies are not used, legacy preview cookies are stripped, and cross-origin redirects receive no internal header. Requests without an owned frame, including worker requests, receive no implicit authorization. Tabs, pending navigation and reads own their lifetime. Closing or navigating away from the final tab revokes access and drains existing requests for at most five seconds; hidden and floating tabs remain consumers. Failed opens, cancellation, owner/workspace disposal, changed root identity and shutdown release resources. No external server process or staging copy is created, so crashes leave no server child or staging files to recover. Original documents and user-owned development servers are preserved. Capability URLs and known tokens are redacted from textual tool results and diagnostics; screenshots remain visual page evidence. + +## Verification + +`npm run test:browser` covers contracts, action policy, profiles, cookie decoding/import, preview-server confinement, annotation context/capture, live-style reversion, and UI state. The three browser Playwright files cover actual Electron page interaction, a deterministic model's tool loop and Ask-mode approvals, live annotation, profile isolation, responsive and floating layout, native-view visibility, local HTML/PDF documents, valid WebM recording, input cancellation, and closing picture-in-picture during capture. Shared activity labels are covered by the desktop, Android, and iOS model tests. + +Validation includes focused browser/context/runtime suites, actual Electron agent discovery and execution, exact temporary-file approval and asset loading, shared listener lifetime, stale approvals, hover interception, cursor cleanup, owner reload and workspace/file-identity revocation. Desktop, Android and iOS activity labels include discovery. Initial feature validation passed: `npm test`, `test:preflight`, 118 browser tests, 266 compaction/runtime tests, all 15 original Electron browser cases, TypeScript, E2E TypeScript, lint, build and focused Android tests. iOS app/test targets pass generic-device build-for-testing; XCTest execution requires a physical device under repository policy. + +PR review follow-up validation passes: 140 browser tests (including real Chromium cross-port credential isolation), 20 Electron browser cases with no flaky retries, TypeScript, E2E TypeScript, lint and production build. Direct user-link coverage verifies discovered CSS/module assets and a separate strict agent grant. Recording coverage decodes three immediate start/stop outputs as video; input coverage includes native keyboard source flags, same-input collisions, and mid-action workspace/global access revocation. + +Real installed-browser import acceptance depends on available profiles and OS permissions. Native-window captures are required for visual checks: a renderer-only Playwright screenshot does not include Electron's native browser view. + + +## Edge cases and recovery + +| Case | Handling / remaining consideration | +| --- | --- | +| Browser is closed, selected tab disappears, or user selects another tab | Open explicitly; generation selection stays pinned, and stale IDs fail instead of retargeting another page. | +| Discovery repeated, excluded, disabled, cancelled, or compacted | Idempotent turn-boundary registration; excluded tools stay excluded; disabled new generations have no gateway; compaction preserves active inventory and correct budgets. | +| Human takeover or earlier parallel action fails | Release held inputs, invalidate already queued actions, and inspect fresh evidence before retrying. Native debugger-source flags distinguish identical physical keyboard input; missing keyboard flags fail closed. Mouse-down/up source metadata is unavailable, leaving a bounded same-button collision ambiguity. | +| Approval waits while a tab navigates, reloads, or changes | Bind page/control revisions and arguments; reject expired approval before input. Hiding an inactive picker does not count as takeover. | +| A target moves or an overlay appears on hover/down | Recheck the resolved element and intercept hit targets across trusted click events; avoid clicking the covering element. | +| Local file URL, temporary document, missing asset, or duplicate preview tab | Use managed `path` previews, exact grants for every document and declared asset, bounded static dependency discovery for direct user opens, and approval for external files; share leases until the last consumer leaves. | +| Traversal, symlink swap, file replacement, workspace-root change or revoked access | Confine paths and pin identities; reject new bytes, revoke affected leases, preserve source files. | +| Failed navigation, cancelled open, active reader, close/reopen race, owner crash | Reservations and tab references prevent premature release; final cleanup has a bounded drain. No stale child process is created. | +| Large page/AX tree, noisy console/network, old screenshots, text-only model | Bounded textual projection, explicit omissions, failure priority, independent screenshot retention and modality filtering. Request fresh focused evidence when needed. | +| Page repeats a capability token or supplies instructions | Redact known textual secrets; treat page content as untrusted evidence. Do not interpret page instructions as user authorization. | +| Cursor, held key/button, recorder, picker or PiP teardown | Matching-world cursor removal, bounded input release and recording/capture lifetime tests cover cancellation and early closure. | +| Ambiguous/hidden/disabled selectors, readiness timeout, unsupported key or target | Return actionable errors; no blind retry or automatic fallback to another browser.
