fix(desktop): reliable composer message queue (#40221)
* fix(desktop): make composer message queue reliable

The queue felt 'dumb' because of three real bugs:

1. Drained-after-interrupt sends went silent. cancelRun sets
   interrupted:true and nothing reset it; submitPromptText's optimistic
   seed preserved it, and the message stream drops every delta while
   interrupted. So Send-now-while-busy and any interrupt+drain submitted
   the next turn into a muted session. Fix: a fresh submit is a new turn —
   seed interrupted:false.

2. Back-to-back queue drains stalled. The drain fires on the busy->false
   settle edge, but busyRef (synced from the busy store by a separate
   effect) can still read true on that same edge, so the drained send hit
   the busy guard, returned false, and the entry was never removed. Fix:
   fromQueue sends bypass the busyRef guard (the queue drain lock
   serializes them); the user path keeps the guard.

3. Double-enter-to-interrupt killed single non-queue turns. The hidden
   450ms timer meant a natural double-tap after sending stopped the agent.
   Fix: empty Enter while busy is a no-op; interrupting is explicit —
   Stop button or Esc.

Also: clean stop (no [interrupted] marker), Send-now works while busy
(promote + interrupt + auto-drain), settle on the interrupted completion
path. Adds regression tests and unblocks the prompt-actions suite by
completing its stale @/hermes mock.

* fix(desktop): float the queue panel as an overlay so the chat doesn't resize

The queue list rendered in-flow inside the composer root, so its height
fed --composer-measured-height (the composer rect drives the thread's
bottom padding + last-message clearance). Queuing a message grew that
rect and the whole chat visibly resized.

Anchor the panel out of flow above the composer (absolute bottom-full,
capped at 40vh with internal scroll). It no longer contributes to the
measured height, so the thread layout stays put and the list overlays the
(already faded) chat. Still collapsible via the panel's own
disclosure header.

* fix(desktop): queue panel collapsed by default + shared border with composer

- Default the queue disclosure to collapsed (compact 'N queued' pill)
  instead of expanded.
- Drop the gap and merge the panel into the composer: square bottom
  corners, no bottom border/radius, and overlap down by the Root's pt-2
  (-mb-2) so the panel's borderless bottom lands on the composer surface's
  top border — one continuous bordered shape.

* style(desktop): tighten queue panel padding

* style(desktop): trim queue-ux comments to house style

* style(desktop): drop 'Cursor' references from comments

Hermes Desktop ☤

Download Documentation Discord License: MIT

The native desktop app for Hermes Agent — the self-improving AI agent from Nous Research. Same agent, same skills, same memory as the CLI and gateway, in a polished native window — chat with streaming tool output, side-by-side previews, a file browser, voice, and settings, no terminal required. Available for macOS, Windows, and Linux.

Chat with the full agentStreaming responses, live tool activity, structured tool summaries, and the same conversation history as every other Hermes surface.
Side-by-side previewsRender web pages, files, and tool outputs in a right-hand pane while you keep chatting.
File browserExplore and preview the working directory without leaving the app.
VoiceTalk to Hermes and hear it back.
Settings & onboardingManage providers, models, tools, and credentials from a real UI. First-run setup gets you to your first message in seconds.
Stays currentBuilt-in updates pull the latest agent and rebuild the app in place.

Install

Already have the Hermes CLI? Just run:

hermes desktop

It builds and launches the GUI against your existing install — same config, keys, sessions, and skills. On first launch Hermes walks you through picking a provider and model; nothing else to configure.

Prebuilt installers

Prebuilt installers are built and distributed via the Hermes Desktop website..


Updating

The app checks for updates in the background and offers a one-click update when one is ready. You can also update any time from the CLI:

hermes update

Requirements

The installer handles everything for you (Python 3.11+, a portable Git, ripgrep).


Development

Want to hack on the app itself? Install workspace deps from the repo root once, then run the dev server from this directory:

npm install          # from repo root — links apps/desktop, web, apps/shared
cd apps/desktop
npm run dev          # Vite renderer + Electron, which boots the Python backend

Point the app at a specific source checkout, or sandbox it away from your real config:

HERMES_DESKTOP_HERMES_ROOT=/path/to/clone npm run dev
HERMES_HOME=/tmp/throwaway npm run dev
npm run dev:fake-boot   # exercise the startup overlay with deterministic delays

Building installers

npm run dist:mac     # DMG + zip
npm run dist:win     # NSIS + MSI
npm run dist:linux   # AppImage + deb + rpm
npm run pack         # unpacked app under release/ (no installer)

Installers are built and uploaded to GitHub Releases manually. macOS/Windows signing & notarization happen automatically when the relevant credentials are present in the environment (CSC_LINK / CSC_KEY_PASSWORD / APPLE_* for macOS, WIN_CSC_* for Windows).

How it works

The packaged app ships only the Electron shell. On first launch it installs the Hermes Agent runtime into HERMES_HOME (~/.hermes, or %LOCALAPPDATA%\hermes on Windows) — the same layout a CLI install uses, so the two are interchangeable. The renderer (React, in src/) talks to a hermes dashboard backend over the standard gateway APIs and reuses the embedded TUI rather than reimplementing chat. The install, backend-resolution, and self-update logic all live in electron/main.cjs.

Verification

Run before opening a PR (lint may surface pre-existing warnings but must exit cleanly):

npm run fix
npm run type-check
npm run lint
npm run test:desktop:all

Troubleshooting

Boot logs land in HERMES_HOME/logs/desktop.log (includes backend output and recent Python tracebacks) — check it first if the app reports a boot failure.

macOS / Linux:

# Force a clean first-launch setup
rm "$HOME/.hermes/hermes-agent/.hermes-bootstrap-complete"
# Rebuild a broken Python venv
rm -rf "$HOME/.hermes/hermes-agent/venv"
# Reset a stuck macOS microphone prompt (macOS only)
tccutil reset Microphone com.nousresearch.hermes

Windows (PowerShell):

# Force a clean first-launch setup
Remove-Item "$env:LOCALAPPDATA\hermes\hermes-agent\.hermes-bootstrap-complete"
# Rebuild a broken Python venv
Remove-Item -Recurse -Force "$env:LOCALAPPDATA\hermes\hermes-agent\venv"

The default Hermes home on Windows is %LOCALAPPDATA%\hermes. Set the HERMES_HOME env var if you've relocated it.
