Extract the open_preview emitter into a shared tools/desktop_ui bridge (one gateway-injected sink, routed by HERMES_UI_SESSION_ID) and add a second desktop-gated tool on top of it: - focus_pane(chat|files|terminal|review|sessions) -> pane.reveal event. The desktop runs each pane's own reveal path (revealDesktopPane table) and only acts on the active window -- a background turn never moves the user's focus (desktop AGENTS.md: offer, don't hijack). open_preview now emits through the same bridge. Both tools are check_fn on HERMES_DESKTOP (zero footprint elsewhere), sitting beside read_terminal/close_terminal in _HERMES_CORE_TOOLS. Deliberately not adding run_slash: letting the agent fire slash commands mid-turn (/model, /new, /clear) fights prompt-cache + conversation invariants.

"""Bridge desktop-only tools to Hermes-desktop renderer events.
|
|
|
|
The preview pane, pane focus, and friends live in the desktop renderer, so
|
|
desktop-gated tools reach them through an emitter the desktop ``tui_gateway``
|
|
installs at session start via :func:`set_emitter`. Everywhere else it stays
|
|
``None`` and the tools report "desktop only". Routing keys off
|
|
``HERMES_UI_SESSION_ID`` so the event lands on the window that owns the turn
|
|
(``_emit``/``write_json`` is ``_stdout_lock``-guarded, so emitting from the
|
|
tool's thread is safe).
