Prowl 2026.6.16

New

• Configurable diff tool: Choose your preferred diff viewer in Settings — Built-in, Hunk (opens in a Prowl terminal tab), FileMerge, Kaleidoscope, or a custom command. The diff badge and Show Diff shortcut both route through this setting. Tools not installed on your system appear disabled in the picker.
• prowl agents CLI command: Run prowl agents (or prowl agents --json) to get a live roster of all active agent panes, including their project, worktree, tab, and current working/idle status.
• Oh My Pi support: Prowl now recognizes Oh My Pi (omp / oh-my-pi) as an agent, detects its working and interrupting states, and shows the Pi icon on tabs running it.

Improved

• Active agent detection now uses per-pane lazy scheduling: cold panes stay idle, recently used panes are checked briefly, and full polling only starts after a known agent runtime is detected. This reduces unnecessary background work.
• Command aliases (such as wrapped bun invocations for Oh My Pi) are now shown with the correct icon in the Active Agents list.

Fixed

• prowl read --json and other JSON CLI output no longer corrupts responses that contain terminal control characters.
