Salvaged from PR #67807 by @f-trycua onto current main. - Foreground gate: discover delivery_mode support from the live tools/list inputSchema.properties (fail closed), not the never-shipped input.delivery_mode capability token - bring_to_front: standalone strict-schema MCP tool (inject_session=False), separate approval scope, requires foreground - Verdict precedence: confirmed > unverifiable (verify before retry) > suspected_noop/refusal (escalate); surfaced as explicit verdict field - Typed cua_browser_* route inside computer_use (browser_route.py) with exact-binding, adapter-injected session, snapshot-scoped refs - Per-Hermes-session backend isolation + release_computer_use_session seam wired into AIAgent.close() - Recorded 0.9 tools/list fixture replaces fabricated capability tokens

"""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, the
|
|
COMPUTER_USE_GUIDANCE prompt block, approval hook, and the skill) live
|
|
alongside this package. See agent/anthropic_adapter.py and
|
|
agent/prompt_builder.py for the salvaged hunks from PR #4562.
