Documentation

README

Excerpt

Browser Core Efficient

Use this skill when operating the workspace-embedded browser and efficiency matters.

Goals

reduce browser tool round trips
reduce large state snapshots
reduce unnecessary screenshots and page text reads
prefer reliable one-call actions over browse-then-browse-again loops

Default Loop

If the target is already known, use browser_act directly with locator signals.
If the target is semantically known but the page is large, use browser_find.
Use browser_get_state only for orientation or when the target is still unclear.
After page-changing actions, use wait_for on the action itself when possible.
Re-read state only if the action result is ambiguous.

This is the opening of the README. Read the full README on GitHub.
