- Fixed critical cross-frame coordinate and screenshot conversion issues to improve reliability in complex page layouts.
- Stabilized browser session management and tab handling to prevent leaks and blocking on session stop.
- Enhanced form interaction by validating fill results and matching state by element identity.

- Explicit focus and blur primitives for interactions.
- Scroll-to-element primitive for navigation.
- Grouped observations support in semantic structure generation.
- Dedicated Harness skill with Browser tool parity.
- Scalable browser capability regression test framework.
Improved
- Refactored DOM processing to decouple from capture orchestration.

July 2026
6 releases: 0.1.3 → 0.1.9
July brought significant stability improvements to BrowserSkill, with a focus on session security, better error handling, and a new observation layer. The CLI gained auto-update support and several critical fixes improved daemon and extension reliability.
Highlights
- Added VOM as the new observation layer integrated into the extension pipeline.
- Implemented session idle timeout enforcement in the daemon.
- Added bsk CLI auto-update support.
- Improved session security by rejecting cross-browser events and preventing tab borrowing across sessions.
- Fixed browser keepalive reconnection handling.
New
- bsk console command for direct interaction.
- VOM observation layer integrated into extension pipeline.
- bsk CLI auto-update support.
- WebSocket connection URL as build-time configuration variable.
Improved
- Session idle timeout now enforced by daemon.
- Tab borrowing now fails closed on confirmation issues instead of failing open.
- Early control return and request-help handoff now preserved across tabs.
- Doctor command now exits with non-zero status on failed checks.
- Error messages corrected to better indicate mistakes with proper command examples.
Fixed
- Borrowed tabs no longer returned into another session's Agent Window.
- Cross-browser session events rejected from non-owners.
- Transient tabs.get errors no longer cause borrow gate to fail open.
