It is not a promise +that every control supports a route; a background capability does not authorize +raw pointer gestures. Window capture, semantic input and arbitrary pointer input +are distinct capabilities. Portal selection does not identify a PID or authorize an unrelated +AT-SPI tree. Wayland seat input cannot provide isolated background coordinates. +Games, custom renderers, protected content, minimized/hidden windows and other +Spaces require explicit capability/error handling; no backend promises universal +background input. + +## Ownership and execution + +Portable DTOs and `AppInputAction` live in `tool-contracts`; the host port lives in +Core. Desktop owns native resources and platform adapters. Assembly must not own +OS APIs, native focus workarounds or concrete capture implementations. + +The app-input pipeline has one execution owner: + +```text +single app_* call ─┐ + ├─ validate → typed input program → dispatch_app_input per step +app_batch steps ──┘ ↓ + one final observation + ↓ + receipts + pixels/AX +``` + +`computer_use_program` owns ordered dispatch, receipts, cancellation checks and +final observation. Single-action aliases compile to the same typed program as +`app_batch`. The former four host methods combining click/text/scroll/key input +with a snapshot have been removed from the internal port. There is no separate +single-action recovery executor that can repeat a mutation or take redundant +intermediate observations. + +A program selects one application and cannot switch target or mode between +steps. Click, text, key chord, scroll, drag and wait steps are all parsed and +validated before any input is dispatched. Structural checks include image IDs, +nonnegative image coordinates, grid dimensions/indices and nonempty OCR targets, +including text/scroll focus targets in later steps. Legacy shorthand coordinates +and node indices use checked integer conversion rather than wrapping onto a +different control. Native providers still validate live bounds and identity. +`dispatch_app_input` performs input +only. A known sequence can avoid intermediate model/AX/OCR/capture work; unknown +search results still require an observation before choosing a result. macOS and +Windows clicks have no implicit per-step settle sleep; explicit `wait_ms_after` +is preserved. A program takes its final observation through the capture provider +instead of multiplying a fixed delay by its step count. + +For an observed search field whose Return-to-search behavior is already known, +a program can combine `app_type_text` with that field as `focus`, followed by +`app_key_chord` with `["return"]`. Inspect the resulting search results before +choosing one. Focus-and-type alone is already one input step. Model-facing schemas +retain this concrete combination for both image and node targets; a batch changes +neither native delivery capability nor authorization. + +The executor checks active owner/generation/target scope before each step and +before final observation. Cancellation interrupts side-effect-free waits. Native +input returns its delivery result so partial delivery is not hidden by dropping +a future. Remaining steps are not run after failure or cancellation. Native macOS gestures also release any presses left unfinished by a failed or cancelled action, so a partial chord or drag cannot leave modifiers or mouse buttons held for the next action. An +observation completing after stop, rebinding or generation change is discarded. + +Receipts distinguish attempted steps, submitted steps, the failing step and +observation failure. A native error may follow partial submission. Neither that +error, a missing screenshot nor an unchanged AX digest authorizes replay. +Submission means accepted by the delivery path, not verified application success; +completion must be established by the resulting application state. + +Main agents can use ComputerUse directly when the host and tool configuration +allow it. The ComputerUse subagent is optional. Delegated execution keeps +`original_user_context` separate from `agent_plan`, with message provenance; +missing original context never becomes foreground permission. Browser automation +is preferred for attached web content, but a browser process name is not an input +authorization boundary for native chrome, dialogs or unattached windows. + +## Session lifecycle and revocation + +The resource lifecycle is `idle → starting → active → stopped|failed`, with an +active observing/background/foreground mode. One Runtime session owns the GUI +resource. Competing ownership returns `control_busy`; it does not create a +second permission owner or Agent loop. + +An explicit start selects mode. Target-scoped observation can establish a +background session for compatible callers, but never foreground authority. +Discovery alone does not create capture. The first app observation binds an +exact window; Linux portal capture binds the consented surface separately from +semantic application identity. Stop/status are idempotent. A stopped generation +requires an explicit restart, not a screenshot-driven resurrection. + +Stop revokes admission and advances generation before cancelling native work, +releasing owned pressed keys/buttons, stopping capture and hiding feedback. +Native Closed/Stop Sharing, cancellation, permission revocation and target loss +use the same owner path. Generation/sequence tokens cross blocking/native worker +boundaries; delayed work cannot borrow a later action's admission. Startup and +cleanup epochs prevent late callbacks from resurrecting or clearing newer state. +Already submitted external effects cannot be rolled back. + +## Observation, coordinates and model transport + +A screenshot returns the authorized native capture's bytes, screenshot ID, +image/native dimensions and coordinate geometry. It does not perform a four-way +display search or require a confirmation crop. Screenshot admission requires a +supported control provider and a bound capture target. Legacy crop, quadrant, +reset-navigation and window hints remain accepted with an explicit ignored-field +notice; they do not select a new surface or grant authorization. Legacy DTOs +remain readable, without advertising their obsolete navigation workflow. + +Image coordinates are meaningful only with the corresponding `screenshot_id`, +`image_content_rect` and `image_global_bounds`. Apply scaling once. Reject unknown +IDs, target changes and invalid geometry. macOS can translate a retained image's +coordinates for pure window movement when the image projection and size remain +valid; resizing or changed projection requires fresh observation. Retina, mixed +DPI, negative origins and cross-monitor movement are acceptance cases. + +Observed node indices refer to retained native identities from that observation. +Do not rebuild a tree and reinterpret an old index. Bound-window input validates +the element's actual owning window, including same-PID foreign-window rejection. +Application-level menu exceptions must be explicit, not a general unknown-window +escape hatch. + +`describe_screen` observes the explicit or bound target. The human foreground app +and physical pointer are separate metadata. Window chrome alone is incomplete AX +content, not successful reading of a document or conversation. Native OCR uses +the authorized pixels. Explicit app AX reads can survive classified surface/frame +or screen-capture-permission failures, marked `capture_preparation_error`, +`capture_status: unavailable` and `control_target_available: false`. Such reads +create no binding and attach no prior target's pixels. Lock, stop, ownership, +generation, revocation and unknown errors cannot use that fallback. + +A text-only screenshot request performs a real text observation. Tool results +preserve structured identities, AX/OCR facts, errors and geometry in the model's +actual result channel; a short summary is not a replacement. Image attachments +retain their bytes and metadata through supported OpenAI-compatible, Responses, +Anthropic and Gemini transports. Model vision capability and transport support +are separate gates. Persisted images remain available to capable later consumers. + +Post-input observation is fresh with respect to the capture provider's guarantee. +macOS marks a host-clock input barrier and waits for a later complete or idle +ScreenCaptureKit sample. Idle can establish unchanged pixels; resize still needs +a valid complete frame. This proves capture timing, not completion of asynchronous +application work. Windows drains WGC frames to the newest available frame; it +does not claim an equivalent input-clock barrier. + +Windows input preparation validates and reuses the live WGC session without +consuming or encoding a frame. Only an actual observation requests pixels. +Explicit action waits subscribe to session changes; Stop, revocation or target +replacement interrupts them immediately, including waits between batch steps. + +## Native input rules + +### macOS + +Retain the selected content window across observations. A sharing-indicator +window appearing earlier in WindowServer order must not replace it. Conflicting +explicit window selection fails; validate a replacement before releasing a live +capture. AX focused-window observation resolves the actual bound window, not an +unrelated Sharing dialog. Missing exact identity is an error. + +For one unmodified left ImageXy click, native application-root AX hit testing may +select an explicitly pressable button, checkbox, radio button or link. The hit +must belong to the exact bound window and contain the point. Do not rank nearby +rectangles, climb ancestors or replace double/right/modifier clicks with AXPress. +Only explicit ActionUnsupported permits a different delivery path; unknown AX +outcomes stop without a duplicate click. + +Text/key `focus` uses retained AX identity or native hit testing and semantic +focus for text controls. Other eligible targets use the exact-window directed +focus route described below. Unknown focus outcomes must not type into an old +field or silently switch to global foreground input. +For explicit text-control focus, typing first uses one `AXSelectedText` mutation +at the retained target: replace the selected range or insert at the caret. +Preflight-confirmed unsupported semantic writing may use directed Unicode input; +an unknown write outcome stops without resubmission. An already focused control +is not focused again, preserving its selection. Semantic Unicode field input +passed the dedicated production Tool fixture; support for other applications +still depends on their native accessibility implementation. + +Explicit foreground mode may use its authorized pointer-focus path. An unknown +AX outcome never implies successful focus. Scroll `focus` is only a coordinate +anchor: resolve it, update virtual pointer position, then scroll; never click the +control under the anchor. + +Directed pointer events use one `CGEventPostToPid` route and exact window/local +coordinates. The existing dynamically resolved `CGEventSetWindowLocation` +routing dependency is checked; its absence is an explicit error. Authenticated +event delivery obtains the event record through `SLEventGetEventRecord` and +copies it into an owned, aligned 248-byte record. It no longer guesses offsets +inside an opaque CGEvent. The getter has a local no-input test; that test does +not establish delivery. The unused temporary foreground-menu activation helper +is removed. No implicit +Command modifier, global foreground activation or human-cursor warp is a substitute. +The directed mouse source is `CombinedSessionState`, with modifier flags set +explicitly to the requested modifiers. A private mouse source itself caused +AppKit to raise inactive windows in the strict fixture; changing only that source +is therefore part of the routing contract, not a reason to add Command. Keyboard +events retain a private source. Event field 58 is set to 1 for window routing; it +is not a click-group identifier and must not be repurposed as one. These event +fields are native adapter details, not application-specific rules. + +#### Target-local focus lifecycle + +`macos_input_focus` prepares the target application's internal active/focus state +without making that process the human desktop's frontmost application. It +validates the exact window ID, current geometry and capture action lease. A +window-addressed down/up focus pair is placed outside the content frame at local +`(-8,-8)`; it must not hit a content control. The requested gesture then uses its +observed target coordinates and original modifiers. There is no implicit Command, +global foreground switch, window raise/restore or human-cursor warp. + +The preparation cache includes generation, PID, window ID, human foreground +identity and activation epoch, so preparation is not repeated for every key or +batch step while stale activation state cannot be reused. There is no app-name +rule or guessed content-control coordinate. Preparation does not depend on an AX +key-state acknowledgement, which normal AppKit windows can omit; fixtures inspect +their own `NSWindow.keyWindow` directly. + +Cleanup validates process-serial identity before touching the target, and skips deactivation if the user has made that target the actual +foreground application. It cannot deactivate a reused PID or reset another +application's focus. The outside-frame focus pair and cleanup belong to the +control lifecycle, not to a model-generated sequence of clicks. + +The production Tool/native fixture passed a five-action background program: +click an ordinary non-AX canvas, type text, invoke the real menu with Cmd+Shift+K, +scroll by 8, then type an emoji. It completed in 466 ms including its one final +observation, excluding model reasoning. The covered target received one content +click with unchanged modifiers, text reached the canvas while the separate text +field remained unchanged, and the menu/scroll actions took effect. Exactly one +outside-frame focus pair prepared the entire program. The observer retained +active/key/frontmost and stacking state, received no input, and the human cursor +matched its baseline. Stop deactivated the internally prepared target. Semantic +Unicode field input also passed in the fixture before the program. + +The standalone raw native runner also passed its one native test (4.62 seconds +including capture and waits), with strict cursor, lifecycle and event-scope +checks. Both runners use ordinary inactive controls and preserve the observer +baseline; neither substitutes a permissive first-click implementation. Unit +coverage includes 143 passing Desktop tests. + +Complete acceptance must verify no off-frame content hit, exactly one requested +content click, correct text destination, unchanged human foreground/key/stacking +state, modifier fidelity, cursor validity and Stop cleanup through the production +Tool pipeline. Native success on these controls will not establish universal +support for every application, game, Space or protected surface. + +Hidden, minimized and unavailable surfaces are distinct from occlusion. A known +locked session yields `SESSION_LOCKED`; unknown session metadata retains normal +capture errors. No unlock, wake or automatic activation is a recovery action. + +### Windows + +Observation and semantic actions share a retained MTA UIA worker/cache. Validate +PID, HWND, generation, enabled state and geometry before supported Invoke, +Toggle, SelectionItem or Scroll operations. Release retained COM references with +the cache; do not rebuild indices during input. + +Standard Unicode Edit/RichEdit text insertion replaces the current selection +through `EM_REPLACESEL`, preserving text outside that selection. An observed +NodeIdx retains UIA identity. ImageXy resolves through the screenshot map and +recursive `ChildWindowFromPointEx` within the bound HWND, then retains that exact +child's UIA element; it does not hit-test a covering application's global point. +Without explicit focus, `GetGUIThreadInfo` reads the bound window thread's focused +native control. PID, UIA process, root HWND, enabled state and read-only state +must match before input. Unsupported OCR/grid or non-edit targets return +`BACKGROUND_TEXT_UNAVAILABLE`; timeout after submission is an unknown outcome, +not a retry. No clipboard, foreground switch or arbitrary whole-value replacement +substitutes for insertion. The point/focus routes and their native fixture have +cross-compile evidence; the Windows fixture has not been executed. + +### Ubuntu + +Portal authorization immediately binds the retained stream to the control +resource. A scope change cannot silently replace that binding in the same +generation; stale-generation work is rejected. Portal sessions retain one +authorized PipeWire remote and stream. Prefer stable +PipeWire serial targeting when available. Frame-size changes invalidate absolute +coordinates. Notify input is the single portal seat transport; do not mix in an +unconsented X11/global path. Portal authorization has a bounded deadline and +explicit local-authorization failure; late responses cannot revive old sessions. +Native-thread Stop schedules release/closure through the retained runtime. + +AT-SPI caches retain bus/object identity and control generation. Default actions +execute once without coordinate fallback. Text insertion uses character caret +and selection offsets with UTF-8 byte length. One selected range is replaced; +unselected text remains intact. Invalid offsets or multiple selections fail +explicitly. The bridge uses canonical `NActions`/`GetName` and `GetNSelections` +wire names rather than relying on known incompatible generated/batch calls. + +## Persistent visual feedback + +The virtual pointer is independent of the human pointer. Its last position lasts +until Stop or target change; only the click ring expires. The arrow uses a rounded +neutral-gray silhouette, soft shadow and a fixed hotspot. Raw model/OCR captures +do not contain the feedback overlay. Input text is not copied into feedback logs. + +Native feedback is nonactivating and click-through. macOS hides it while the +target region is covered, retaining its position for reappearance. Windows uses +preview feedback conservatively when native visibility cannot be established. +Ubuntu preview does not invent a Wayland global overlay. Reduced-motion retains +static position feedback without movement transitions. + +The product surface shows authoritative target, mode, status and Stop while the +chat card is collapsed. Preview sampling is bounded and stops when unobserved; +React component lifetime does not own native capture lifetime. Generation/target +checks discard stale preview responses and device-switch results. + +## Remote and upgrade compatibility + +| Scenario | Required behavior | +|---|---| +| Remote workspace | Existing SSH/Docker workspace refusal; never operate the controller's local GUI as fallback | +| Remote control | Use the executing host's registered provider; local-only consent must report `local_authorization_required`; task cancellation remains reachable | +| Peer Device | Follow operation-registry routing and negotiated provider capability; controller permission is not peer permission; CLI without GUI rejects explicitly | +| Detached Dispatch | Headless execution has no implied GUI capability or submitter UI dependency; require an explicitly negotiated target provider | + +Missing new capabilities on old peers mean unknown/unsupported. Portable fields +use conservative defaults; old payloads remain readable. Do not delete/reset +persisted sessions, settings or profiles to repair incompatibility. Internal Rust +port cleanup does not authorize changing persisted or cross-version wire shapes. +Local fixtures and unsupported-host unit tests are not remote end-to-end evidence. + +## Verification and acceptance + +The final integration baseline is upstream `178e9b555`. The macOS Desktop debug +build, 65 Core tests, 143 Desktop tests, ten control-card/API frontend tests, +frontend TypeScript check and Windows production-source cross-compilation passed +on this baseline. The broader `check:web` gate stops at four existing typography +violations in unchanged mobile `chat.scss` and `host-queue.scss`; it is not a pass. + +Focused validation includes 65 Core Computer Use tests (including the 45 tool +schema/execution tests), 143 Desktop tests, eight prompt catalog tests and 19 +Computer Use contract tests. Opt-in native fixtures ignored by unit-test commands +do not count as native passes. The full macOS Tool program above was executed +separately and passed. Its fixture records hardware idle time and activation +history, retains strict failure assertions, and never restores observer focus to +manufacture a pass. Native Windows, Wayland and remote execution remain untested. + +Run focused checks from the [Desktop Computer Use guide](../../src/apps/desktop/src/computer_use/AGENTS.md) +and [Core guide](../../src/crates/assembly/core/AGENTS.md). A build-only result, +ignored native test or permissive first-click fixture is not a successful strict +background-input run. + +| Area | Recorded evidence | Remaining scope | +|---|---|---| +| macOS strict production Tool pipeline | Five-action non-AX canvas/text/menu/scroll/emoji program in 466 ms including final observation; one content click and one outside-frame focus pair; observer foreground/key/stacking and human cursor unchanged; no observer input; Stop deactivated target | Wider applications, cross-Space behavior and visual system Sharing UI acceptance | +| macOS capture/feedback | Dedicated native fixtures exercised obscured target pixels, binding retention, movement/resize, hidden/minimized errors, closure, pointer lifetime and locked-session rejection | System Stop Sharing interaction and broader platform/application matrix | +| Linux text semantics and scope | 45 focused tests; a separate real GTK/AT-SPI fixture verified selected text replacement while unselected text survived | GNOME Wayland portal consent, real PipeWire/seat input and sharing UI | +| Windows text semantics | Production-source cross-compilation, including Edit/RichEdit selection replacement | Interactive Windows native delivery, WGC border/stop and foreground preservation | +| Remote scenarios | Scope/unsupported-provider contracts | No remote-workspace, Remote Connect, Peer Device or Detached Dispatch end-to-end GUI validation | + +The macOS strict fixture builds before opening windows, initializes the host, +uses separate application bundle identities, and waits for a bounded hardware +input idle interval before foreground setup.

The **668** Tauri commands remain implementation-audit evidence only.

Current coverage is **48 direct**, **62 delegated**, **212 interactive**, and **0 unsupported**. - Stable behavior becomes a typed `operation` or `option` with a JSON input contract and a native product-control provider. Agents never receive raw Tauri commands. -- `OpenBitFunControl list` and `search` return compact pages with a `nextCursor`; the catalog can grow without a fixed total-size ceiling.

Neither the full catalog nor its 322 documented items enters the system prompt. - Discovery and contract lookup do not depend on React or a visible window. Ordinary config-backed options are read, written, and read back by one Product Assembly ConfigService executor shared by Desktop, CLI, and headless surfaces. Only host-native operations/provider options and presentation routes install surface adapters; missing adapters return explicit unavailability without local fallback. Read-only agents may only discover and inspect entries. ## 防腐化门禁 / Anti-drift gates diff --git a/docs/interactive-capabilities/capabilities.json b/docs/interactive-capabilities/capabilities.json index a2abd684b8..d2c2439e36 100644 --- a/docs/interactive-capabilities/capabilities.json +++ b/docs/interactive-capabilities/capabilities.json @@ -4,7 +4,7 @@ "title": "OpenBitFun Playbook", "origin": "https://playbook.openbitfun.com", "source": "src/shared/interactive-capabilities/catalog.json", - "digest": "6587344a6b5e75a80457ea4ba2670bf37cf3038bdb436089ae402eb7b5a5a025", + "digest": "d2710a9488e6f021e11ece435e8d067a9285903c26f20f5bc0b586ac46d67e6d", "ownerDigest": "c0e5c187cf62bc6ed06196ce8520b3eb427bf268cf24659b72d2552fb1d99c54", "searchAcceptance": [ { @@ -138,11 +138,11 @@ "features": 22, "settings": 21, "userFacing": 43, - "documentedItems": 320, + "documentedItems": 322, "controlCoverage": { "direct": 48, - "delegated": 61, - "interactive": 211, + "delegated": 62, + "interactive": 212, "unsupported": 0 } }, @@ -4773,7 +4773,9 @@ "browser-discovery", "launch-connect", "default-cdp", - "agent-actions" + "agent-actions", + "control-session-preview", + "stop-control-session" ], "kind": "query", "risk": "read", @@ -5135,6 +5137,97 @@ "pageId": "tools.execution" } }, + { + "id": "feature.computer-use:open:control-session-preview", + "capabilityId": "feature.computer-use", + "itemIds": [ + "control-session-preview" + ], + "kind": "open", + "risk": "ui", + "executionHost": "presentationSurface", + "availability": { + "desktop": { + "available": true + }, + "cli": { + "available": false, + "reason": "This delivery profile has no live presentation surface" + }, + "peer": { + "available": true, + "requiredCapabilities": [ + "product_control_v1", + "product_control_presentation_v1" + ] + }, + "remoteControl": { + "available": true + }, + "detachedDispatch": { + "available": false, + "reason": "This delivery profile has no live presentation surface" + } + }, + "inputSchema": { + "type": "object", + "additionalProperties": false + }, + "outputSchema": { + "type": "object", + "additionalProperties": true + }, + "openReason": "unstructuredInteraction", + "presentationTarget": { + "kind": "settings", + "pageId": "tools.execution" + } + }, + { + "id": "feature.computer-use:delegate:stop-control-session", + "capabilityId": "feature.computer-use", + "itemIds": [ + "stop-control-session" + ], + "kind": "delegate", + "risk": "execute", + "executionHost": "workspaceHost", + "availability": { + "desktop": { + "available": true + }, + "cli": { + "available": true + }, + "peer": { + "available": true, + "requiredCapabilities": [ + "product_control_v1" + ] + }, + "remoteControl": { + "available": true + }, + "detachedDispatch": { + "available": true + } + }, + "inputSchema": { + "type": "object", + "additionalProperties": true + }, + "outputSchema": { + "type": "object", + "additionalProperties": true + }, + "delegateTools": [ + "ComputerUse" + ], + "presentationTarget": { + "kind": "settings", + "pageId": "tools.execution" + } + }, { "id": "feature.skills:query", "capabilityId": "feature.skills", @@ -21712,12 +21805,14 @@ "highlightsZh": [ "启用或停用 Computer Use", "连接或断开受支持的浏览器", - "检查并打开系统权限设置" + "检查并打开系统权限设置", + "查看当前控制目标与预览，并随时停止控制" ], "highlightsEn": [ "Enable or disable Computer Use", "Connect or disconnect a supported browser", - "Inspect and open OS permission settings" + "Inspect and open OS permission settings", + "Inspect the current control target and preview, and stop control at any time" ], "items": [ { @@ -21804,6 +21899,36 @@ "After authorization, use the latest screenshot or element-location result to click, type, scroll, and inspect the visible interface" ] } + }, + { + "id": "control-session-preview", + "titleZh": "在控制状态卡片查看当前目标、模式与授权画面预览", + "titleEn": "Inspect the current target, mode, and authorized capture preview in the control card", + "control": { + "kind": "open", + "reasonCode": "unstructuredInteraction", + "reasonZh": "“在控制状态卡片查看当前目标、模式与授权画面预览”需要活动会话及用户展开卡片；预览仅包含当前授权目标和虚拟指针。设置入口仅用于配置，不会启动控制。远程设备需要对应 Desktop 宿主支持，不可回退到本机画面。", + "reasonEn": "“Inspect the current target, mode, and authorized capture preview in the control card” requires an active session and expanding its card; the preview contains only the authorized target and virtual pointer.

An input event being submitted does not prove the application accepted it. A changed AX digest does not prove the intended content was delivered, and an unchanged digest does not prove failure. Before retrying a mutation, check the current target content and any execution error so a delayed action is not duplicated. Use `wait` or a supported `app_wait_for` predicate when the UI is still changing. A wait timeout reports an unmet observation condition, not permission to repeat a send or other mutation. -Never assume focus, display, or cursor position. For multi-display setups, inspect display state and pin a display before actions that must happen on a specific screen. +Choose recovery from the error and fresh evidence. Stale references require a new observation; sparse accessibility requires target capture/OCR; a closed or unavailable target requires resolving that target's state. Do not use a fixed retry count to decide the next tactic, and do not replace a failed capture with desktop pixels from another application. + +# OS-Specific Control Profile -Do not click or press Enter blindly. If the UI state is unknown, call `ComputerUse` with an observation action such as `get_app_state`, `describe_screen`, `list_apps`, `locate`, or — only when the primary model supports images — `screenshot` / `build_interactive_view`. +Use the OS reported by the execution host and the capabilities returned by its tools. -Use paste for any multi-line text, CJK/Japanese/Korean/Arabic text, emoji, long text, file paths, messages, or search queries. Use type_text only for short Latin text into a known focused field when paste is unavailable or inappropriate. +On macOS, app-scoped shortcuts use `command`, `option`, `control` and `shift`. Persistent window capture and directed application input allow supported background operations. Global clipboard shortcuts and application activation are foreground operations, not recovery steps. -Use keyboard before mouse. Enter/Return confirms default actions, Escape cancels or closes, Tab and Shift+Tab navigate focus, Space toggles focused controls, and standard shortcuts handle clipboard, find, save, new tab, close, and address/search fields. +On Windows, prefer observed UI Automation nodes and the selected window's capture. Use `control`, `alt`, `shift` and `meta` as appropriate for supported shortcuts. Some applications or actions require foreground input; follow the reported capability instead of assuming a background key event succeeded. -When mouse is required, prefer accessibility or OCR targets over guessed coordinates. If you need coordinates, use coordinates returned by tools such as `locate` or `move_to_text`, not coordinates guessed from an image. +On Linux, especially Ubuntu, use AT-SPI semantic actions where supported. Portal/PipeWire observation and portal seat input have separate capabilities: permission to capture a selected surface does not imply arbitrary background mouse or keyboard control. Follow the host's declared scope and unsupported states. -If the same GUI tactic fails twice, switch strategy: use keyboard navigation, app state, OCR, browser automation, scripts, or ask the user for the missing context. +For a model that can see images, observe the selected window and act on its attached screenshot, including controls with no AX/OCR text. Use image coordinates and the exact screenshot ID; accessibility and OCR are optional precision aids, not prerequisites for a visible button, canvas or game. Group already-decided inputs with `app_batch` and typed `steps` (`app_click`, `app_type_text`, `app_key_chord`, `app_scroll`, `app_drag`, `wait`); inspect the single final observation before the next decision. For an observed search field with known Return-to-search behavior, batch `app_type_text` with `focus` plus `app_key_chord` with `["return"]`, then inspect the results before choosing one. Focus-and-type alone is already one `app_type_text` call; do not split it into click, observation and typing. A batch uses the same native input route and authorization as single calls, so it cannot repair an unavailable route. Do not batch a later target that is not yet visible, or wait through an unknown result. Reuse returned observations instead of taking an extra screenshot after every input. `app_drag` uses observed `from`/`to` image targets and `duration_ms`. + +Image coordinates identify a location; they do not guarantee that the host can deliver every gesture in background mode. If a result reports `BACKGROUND_FOCUS_UNAVAILABLE` or `BACKGROUND_POINTER_UNAVAILABLE`, keep the current mode and inspect the returned observation for a supported semantic control or known app shortcut. Do not cycle through equivalent coordinate calls, restart capture, or switch to foreground to repair that capability error. If the required interaction still cannot be performed within the user's authorization, explain the concrete limitation; request additional scope only when it is actually necessary. # Text-Only Operation (when the primary model cannot view screenshots) -When Runtime Context indicates the primary model does not support image understanding, the vision-only actions — `screenshot`, `build_interactive_view`, `interactive_click`, `build_visual_mark_view`, `visual_click` — are unavailable: they are absent from your tool schema, `screenshot` returns no image (`screenshot_unavailable: true`), and the other four return NOT_AVAILABLE. Do NOT retry them and do NOT call them to verify — they cannot help you see. Instead: +Use `describe_screen` and `get_app_state` to read the selected application's accessibility and OCR observations. Prefer `describe_screen` when the AX tree is sparse: it returns `ocr_text`, `ocr_status` and any `ocr_error` from the authorized capture. These are actual recognized text and geometry, not a model-generated description of unseen pixels. + +Do not call image-only view actions or choose image coordinates without seeing their image. `screenshot` is absent from the text-only schema; if an older call reaches it, its text-only compatibility path obtains a real `describe_screen` observation rather than supplying an image or a fake successful capture. Do not use it as a separate vision capability. -- **Observe with `describe_screen`** — it returns a text snapshot (frontmost app, `ax_tree_text` with `node_idx`s, `ui_tree_text`, pointer, displays) with no image. This is your eyes. Call it before acting when state is unknown, and after an action to verify `ax_state_digest` changed. -- **An empty `ax_tree_text` is an answer, not a truncated result.** The same result carries `ax_tree_status` and `ax_tree_note` explaining why it is empty — no frontmost app, an app running with no window, a WebView that exposes no tree, or a missing Accessibility permission — and which tactic to switch to. Calling `describe_screen` again returns exactly the same thing. Never conclude your tool output is being cut off; act on the note instead. -- **Do not build your own eyes out of `screencapture`.** Shelling out to capture the screen and passing the file to an image-analysis tool costs an extra model round-trip per glance, returns prose rather than clickable coordinates, and misreads the screen often enough to send you down false paths. `describe_screen`, `get_app_state`, `locate` and `move_to_text` return exact targets — use them. -- **Target with AX / OCR, never guessed coordinates** — `click_element`/`app_click` with `node_idx`/`text_contains`/`title_contains`/`role_substring`; `move_to_text`/`click_target` with `target_text` (+ `move_to_text_match_index` when several OCR hits are returned as text candidates). -- **Prefer keyboard** — `key_chord` shortcuts (command+F search, Tab/Shift+Tab focus, Return confirm, Escape cancel) and `paste` (clipboard) for CJK / long text before `type_text`. -- **Drive hard-to-reach apps directly** — `run_apple_script` (macOS) for messaging/desktop apps whose AX tree is sparse. -- If an AX/OCR target keeps failing twice, switch tactic immediately (different `node_idx`, different text needle, keyboard, or AppleScript). A recovery hint may tell you to "run screenshot" only when the model supports images — in text-only mode ignore that and use `describe_screen` + the alternatives above instead. +Read `ax_tree_status`, `ax_tree_note`, `ocr_status`, `ocr_error` and any explicit truncation note. Empty accessibility alone does not mean all content is unavailable. If OCR exposes the needed text, continue with an app-scoped `ocr_text` target or an observed accessibility node and `app_type_text`. If neither source exposes the necessary content, report that limitation. Do not guess coordinates, build shell-based eyes, activate another application or claim verification without observation. # Browser Work @@ -74,17 +80,19 @@ For websites and web apps, route in this order: 1.
