It persists the active handoff and completion condition, focuses the declared tab, and returns immediately without pausing browser observations or mutations; explicit **Pause agents** remains available when the page must stay unobservable. +- Replaced blocking human handoffs with task-owned attention notices. Agents can request, inspect, resolve, or dismiss a notice without popup acknowledgement; open notices do not block ordinary commands or task cleanup. Legacy handoffs migrate without restoring a lock, and stale notice IDs cannot clear newer requests. Explicit Pause, ownership, sensitive-field restrictions, and configured Commit review remain independent. - Enabled YOLO mode for new and legacy default state so recognizable consequential controls execute in the original `browser_act` call. Turning YOLO mode off restores staged Commit review. Task ownership, origin policy, revision checks, credential isolation, and all other Standard boundaries remain enforced. +- Preserved existing permissive-mode settings and managed 1Password defaults during the notice cutover, including GUI-host executable discovery and legacy created-tab provenance sanitization. - Replaced the Chrome Bridge v1 runtime with the AgentTab 2.0 release candidate: a Rust production host over OS-native local IPC, nine task-scoped Standard methods, explicit resumable capabilities, a developer-only tenth method, TypeScript and Python SDKs, MCP and OMP adapters, a transactional installer, and a minimal extension. Consequential controls now use a two-party Commit flow: `browser_act` stages an exact effect, the popup approves the durable review record without executing it, and the requesting task must consume its private one-use token through `browser_commit`. - Added explicit `browser_finish` lifecycle finalization across Core RPC, the extension, TypeScript and Python SDKs, CLI, MCP, OMP, and Pi. Automatic cleanup tracks tab provenance, closes task-created tabs, retains adopted tabs, ungroups retained tabs, and releases ownership; popup policy can require confirmation or retain all tabs, while active handoff, Commit review, and in-flight work defer cleanup without destroying resumability. - Fixed OMP adapter compatibility with providers that reject top-level union tool schemas. `browser_open` and `browser_snapshot` now expose provider-compatible object schemas while retaining strict runtime validation for their mode-specific parameters. diff --git a/README.md b/README.md index df5669d..2a0385e 100644 --- a/README.md +++ b/README.md @@ -6,7 +6,7 @@ > Give an agent a tab, not the keys to your browser. -AgentTab lets an agent work in your existing signed-in Chrome profile without giving it unrestricted control of the profile.
