Extra Release Notes — v0.2.5

Release Date: September 18, 2026
Release Title: Computer-Use Acceleration Suite (Atomic Input Batching, Settle Normalization, Browser Crash Recovery Auto-Suppression, and Anti-Blind Completion Protocol)
Target Systems: Windows 10/11 (x64 / ARM64) & macOS (Apple Silicon / Intel)

1. Executive Summary & Problem Resolution (v0.2.5)

In live end-to-end benchmark testing across real desktop automation workflows (file management, web research, document editing, and multi-tab browser workflows), critical performance and robustness breakthroughs were achieved, reducing compound task durations from 365 seconds down to 26 seconds (93% speedup):

1. Multi-Format Sleep Parameter Normalization (extra_batch_actions)

  • Problem: When language models generate compound hardware action batches, sleep steps frequently pass varied parameter names ("duration_ms", "duration", "seconds", "delay_ms"). The engine previously strictly expected "ms" or "delay", causing batch sleep actions to fall back to a default 100ms. In browser workflows, this caused hotkey and typing actions to fire before web pages or bookmark dialogs had mounted.
  • Fix: Both Windows and macOS input engines now seamlessly parse and normalize ms, duration_ms, seconds (multiplied to ms), delay_ms, and duration.

2. Browser Crash Recovery Modal Auto-Suppression

  • Problem: If a previous automation task terminated a browser process forcefully (e.g. Stop-Process msedge -Force), Chromium-based browsers (Edge, Chrome) record an unclean shutdown and display the blocking modal prompt: "Microsoft Edge closed unexpectedly. Restore pages?". This prompt hijacked keyboard focus and blocked tab-wide shortcuts like Ctrl+Shift+D.
  • Fix: The application launcher (extra/core/platform/windows/shell.py) now automatically injects --hide-crash-restore-bubble and --no-first-run into all Edge and Chrome launches. Browsers launch clean, isolated, and immediately receptive to keyboard input.

3. Anti-Blind Completion & Anti-Stall Guardrails

  • Problem: Models frequently called extra_screenshot and extra_task_complete in the exact same tool-calling turn, declaring completion blindly without ever receiving or inspecting the verification visual state. Additionally, large accessibility dumps (extra_inspect_ui) triggered multiple paged view_file calls that burned 40+ seconds of context latency.
  • Fix: Enforced the Strict Anti-Blind Completion Mandate (Turn N captures/inspects; Turn N+1 verifies and completes). Added strict prohibitions against accessibility dump paging and PowerShell HWND hunting loops.

Verification

  • All 1,790 unit tests passed.
  • Verified in live desktop execution reducing browser workflow duration to 26 seconds flat.
