+"""Computer use toolset — universal (any-model) macOS desktop control.
+
+Architecture
+------------
+This toolset drives macOS apps through cua-driver's background computer-use
+primitive (SkyLight private SPIs for focus-without-raise + pid-scoped event
+posting). Unlike #4562's pyautogui backend, it does NOT steal the user's
+cursor, keyboard focus, or Space — the agent and the user can co-work on the
+same machine.
+
+Unlike #4562's Anthropic-native `computer_20251124` tool, the schema here is
+a plain OpenAI function-calling schema that every tool-capable model can
+drive. Vision models get SOM (set-of-mark) captures — a screenshot with
+numbered overlays on every interactable element plus the AX tree — so they
+click by element index instead of pixel coordinates. Non-vision models can
+drive via the AX tree alone.
+
+Wiring
+------
+* `tool.py`       — registers the `computer_use` tool via tools.registry.
+* `backend.py`    — abstract `ComputerUseBackend`; swappable implementation.
+* `cua_backend.py`— default backend; speaks MCP over stdio to `cua-driver`.
+* `schema.py`     — shared schema + docstring for the generic `computer_use`
+                    tool. Model-agnostic.
+* `capture.py`    — screenshot post-processing (PNG coercion, sizing, SOM
+                    overlay if the backend did not).
+
+The outer integration points (multimodal tool-result plumbing, screenshot
+eviction in the Anthropic adapter, image-aware token estimation, approval
+hook, and the skill) live alongside this package. See
+agent/anthropic_adapter.py for the salvaged hunks from PR #4562. Model-facing
+guidance (workflow, background-first, the escalate ladder, safety) lives in
+the tool's schema description and each action result's `verdict`, not a
+separate system-prompt block.

+Cross-platform Computer Use readiness + macOS permission helpers.

+something different on each:
+
+  * macOS — explicit TCC grants (Accessibility + Screen Recording). cua-driver
+    reports/requests them via ``permissions status`` / ``permissions grant``.
+    The grants attach to cua-driver's OWN identity (``com.trycua.driver`` /
+    the installed ``CuaDriver.app``), NOT Hermes — so no Hermes entitlement is
+    involved, and ``grant`` launches CuaDriver via LaunchServices so the macOS
+    dialog is attributed correctly.
+  * Windows — no TCC toggles; the UIAccess worker (``cua-driver-uia.exe``) may
+    trip a SmartScreen prompt on first run. Readiness == driver health.
+  * Linux — assistive control via the X11/XWayland stack. Readiness == driver
+    health.
+
+The universal signal on every platform is ``cua-driver doctor --json`` (binary
+integrity + platform support). ``computer_use_status`` folds that together with
+the macOS permission detail into one payload for the desktop card, the

+"""Vision-routing decisions for ``computer_use`` capture results.
+
+Background
+----------
+``computer_use(action='capture', mode='som'|'vision')`` returns a
+``_multimodal`` envelope containing the captured screenshot. That envelope
+is delivered back to the **active session model** as the tool result. When
+the active main model has no vision capability (e.g. text-only or
+text+code-only models), or when the active provider rejects multimodal
+content inside tool-result messages, the screenshot trips a 404 / 400 at
+the provider boundary and the agent loop reports a hard tool failure.
+
+Issue #24015 reports this regression for the ``cua-driver`` backend:
+configuring ``auxiliary.vision`` (a dedicated vision-capable model) in
+``config.yaml`` was silently ignored — the screenshot was still routed at
+the *main* model and failed with HTTP 404 ``No endpoints found that
+support image input`` even though a perfectly good vision backend was
+sitting in config waiting to be used.
+
+This module centralises the small policy decision: should a captured
+screenshot be returned as multimodal content (main model handles vision
+natively) or pre-analysed via the auxiliary vision pipeline so the main
+model only ever sees text?
+
+Behaviour (mirrors ``vision_analyze`` for consistency)
+------------------------------------------------------
+* If the user explicitly configured ``auxiliary.vision`` (any of
+  ``provider``, ``model``, or ``base_url`` non-empty / not ``"auto"``),
+  the screenshot is routed through the aux vision pipeline. Users who
+  pay for a dedicated vision model usually want it used.
+* Otherwise, if the user explicitly declared the active model vision-capable
+  via ``model.supports_vision`` / provider model config, return ``False``.
+  This is the escape hatch for custom/local OpenAI-compatible VLM routes that
+  are absent from models.dev and provider allowlists.
+* Otherwise, if the active main model+provider can carry an image inside
+  a tool-result message AND the model reports ``supports_vision=True``
+  in models.dev metadata, return ``False`` (use the multimodal path).
+* In every other case (non-vision main model, provider that does not
+  accept multimodal tool results, lookup failure), route through aux
+  vision so the main model receives a text description it can act on.
+
+The decision intentionally fails *closed* (i.e. towards aux routing) when
+metadata is missing or ambiguous: returning a screenshot to a model that
+cannot read it is a hard tool failure, while routing it through aux costs
+one extra LLM call and yields a usable description.
