# GUI profile

> Requirements for browser and desktop environments as worlds.

Adds to Core:

* Channels: a GUI world MUST offer `screenshot` (`image/jpeg` or `image/raw`) and at least one of `dom` or `a11y_tree` (`text/event+json`) with keyframe/delta support (AWP-OBS-004). `[AWP-GUI-001]`
* Action types: a GUI world MUST offer `pointer_move`, `pointer_click`, `key_input`, `scroll`, and `navigate` with the normative param schemas published in [`schemas/v0.1/profiles/gui-actions.schema.json`](https://github.com/Hyperduality/agent-world-protocol/blob/main/schemas/v0.1/profiles/gui-actions.schema.json) (viewport-relative coordinates; the `_px` suffix is the documented exception to AWP-UNI-001). `[AWP-GUI-002]`
* Time model: streaming is REQUIRED; lockstep is OPTIONAL and, when offered, MUST follow the sim-profile lockstep rules (AWP-TIM-009..012) for deterministic page testing. `[AWP-GUI-003]`
* Approval: `navigate` to a URL outside the manifest's declared allowlist and every action class that enters credentials MUST be declared `requires_approval: true` (AWP-APR-001). `[AWP-GUI-004]`
* Safe state: `safety_policy.safe_state.behavior` MUST be `hold` (no further input is injected) with `watchdog_ms` ≤ 10000. `[AWP-GUI-005]`
