Updates

  • GPT-5 reasoning effort matches model version — Reasoning effort tiers (including none and xhigh) are now offered only for the GPT-5 variants that support them, so --variant no longer surfaces options a given model would reject. See Controlling reasoning effort.
  • Diff annotation polish — The session UI diff view tightens up comment indicators, gutter behavior, and light/dark syntax colors for better readability.

Bug fixes

  • Toggle file selections off — Clicking a file selection a second time now clears it, so you can undo a selection without picking a different one first.
  • Cleaner draft comment interactions — Starting or dismissing a draft comment now clears the underlying selection consistently and no longer competes with hover state.
  • Animated reasoning header restored — The reasoning header in the TUI shows an animated spinner again while thinking, and its gradient dims when expanded so the collapsed and open states are easier to tell apart.
  • Background process and test tools restored — bash_background, process_output, list_processes, kill_process, and test_run are available to agents again after being dropped in an earlier merge. Agents can start long-running commands like dev servers and watchers, read their output, and run the project’s tests with structured pass/fail results. See Built-in tools.
