Austin Pickett ac76bbe21f fix(desktop): triage batch of GUI quality-of-life fixes (#37536)
* fix(desktop): triage 24 GUI quality-of-life fixes across sidebar, composer, tool cards, messaging, and platform plumbing

A grab-bag of high-leverage UX fixes plus a few backend touches that the
GUI needs to behave correctly on Windows.

Sidebar / sessions
- Decrement $sessionsTotal on delete + archive so "Load N more" stops
  claiming removed rows are still on the server.
- Hide the "Group by workspace" toggle when no unpinned sessions exist.
- Accept Cmd/Ctrl+N as a "new session" accelerator (in addition to bare
  Shift+N), and render the kbd hint per-platform.
- Switch the statusbar to overflow-x-clip so untitled sessions don't
  paint a horizontal scrollbar at the bottom of the window.

Messaging + Cron
- Add [-webkit-app-region: no-drag] to the page-search input so clicks
  reach the field instead of routing to the OS window-drag handler.
- Replace single-letter PlatformAvatar with brand glyphs from
  @icons-pack/react-simple-icons (telegram, discord, matrix, signal,
  whatsapp, mattermost, wechat, qq, ...). Letter monogram fallback for
  Slack / Dingtalk / Feishu / WeCom (removed from Simple Icons at brand
  owner request).
- Drop the duplicate "Create first cron" button in the empty state.

Composer
- Dedupe pasted images by (name, size, lastModified, type) instead of
  Blob identity; Chromium hands us the same screenshot via both
  clipboard.items and clipboard.files with fresh File instances.
- Enable spellcheck on the contentEditable, configure Chromium's
  spellchecker with the system locale on whenReady, and add
  replaceMisspelling + "Add to dictionary" entries to the context menu.
- Render user messages through a minimal markdown pipeline (inline
  backtick code + fenced ``` blocks) while keeping @file:/@image:
  directive chips intact.
- max-h-[60vh] overflow-y-auto + collisionPadding on the prompt-snippet
  submenu.
- Bake cursor-pointer into the <Button> primitive (with
  disabled:cursor-default) and into titlebarButtonClass.

Dialogs + tabs + version
- Default DialogContent now has max-h-[85vh] overflow-y-auto so long
  bodies scroll instead of falling off-screen.
- Right-rail preview tabs close on middle-click (button === 1), with an
  onMouseDown swallow to suppress Chromium autoscroll.
- New refreshDesktopVersion() helper called from About mount, after
  every update check, and on throttled window focus so About reflects
  the just-installed binary.

Keys + Artifacts + Terminal
- Drop the global "Show advanced" toggle in KeysSettings. Provider
  groups now default-expand when they have any key set.
- Extend openExternalUrl to handle file:// via shell.openPath, with
  showItemInFolder fallback when the OS can't open the file.
- New lib/ansi.ts SGR parser + <AnsiText> component, applied to
  terminal/execute_code tool output.
- ToolView gained stdout / stderr / rendersAnsi; tool-fallback renders
  the two streams as separate labeled blocks with stderr in a neutral
  tone (not destructive — many CLIs log info on stderr).
- Drop 'stderr' from ERROR_MSG_KEYS in tool-result-summary.

Paths + platform
- resolveHermesCwd skips process.cwd() when packaged and prefers a
  user-configurable default project directory.
- New hermes:setting:defaultProjectDir:{get,set,pick} IPC handlers +
  preload bridge + global.d.ts typing + a "Default project directory"
  row in Sessions settings.
- FileOperations.delete_path(path, recursive=True) on the abstract
  base; ShellFileOperations.delete_file rewritten to run a cross-
  platform python3 -c snippet so deletes work on Windows shells (which
  have no rm/rm -rf). Fallback to `python` when `python3` isn't on PATH.
- README troubleshooting block split into macOS/Linux + Windows
  PowerShell recipes.
- Tightened renderer favicon links in index.html + added color-scheme
  and theme-color meta.

Backend lifecycle (renderer-side mitigation)
- New noteSessionActivity() heartbeat + session.ts watchdog: an
  8-minute silence on the stream auto-clears stuck $workingSessionIds
  entries so "Session Busy" never gets permanently wedged. Wired into
  useSessionStateCache so every state update refreshes the timer.

i18n spike
- docs/desktop-i18n-rfc.md scoping a future language-switcher PR
  (recommends react-intl, audits IME/RTL/CJK in the composer +
  chat bubbles, 4-PR rollout plan, ~3-4 eng-weeks for the first
  non-English locale).

* fix(desktop): replace native OS scrollbar in portaled dropdown menus

Radix's DropdownMenuPrimitive.Portal renders content under document.body,
outside the `.scrollbar-dt` scope on #root. Whenever a menu's max-height
clipped its content (even by a pixel — common for the composer "+" menu
that opens upward near the bottom of the window), the user saw the OS's
chunky native scrollbar painted across the whole menu.

Bake a thin, slot-styled scrollbar onto DropdownMenuContent and
DropdownMenuSubContent via [scrollbar-width:thin] + WebKit pseudo-element
arbitrary variants. The submenu also gets a max-h tied to
--radix-dropdown-menu-content-available-height so long snippet lists scroll
cleanly instead of running off the bottom of the viewport. Drop the now-
redundant max-h-[60vh] override on the prompt-snippet submenu.

* fix(desktop): unbork dropdown menu — submenu opens, parent isn't a circle

Two regressions from the previous dropdown-scrollbar fix:

- The parent menu rendered as a rounded oval. Long Tailwind v4 arbitrary-
  variant strings like [&::-webkit-scrollbar-thumb]:rounded-full inside a
  cn() call were being mis-resolved so the `rounded-full` leaked onto the
  menu container itself. Replaced the whole tower of arbitrary variants
  with a real `.dt-portal-scrollbar` class in styles.css that mirrors what
  `.scrollbar-dt` already does for #root descendants. Plain CSS, no Tailwind
  parser ambiguity.
- The Prompt snippets submenu didn't open. Radix publishes
  --radix-dropdown-menu-content-available-height on Content but NOT on
  SubContent, so the `max-h` bound to that variable computed to 0 and the
  submenu collapsed to zero height. Switched SubContent to a fixed
  max-h-80 (≈20rem) which is plenty for a snippet list and never collapses.

* fix(desktop): promote prompt snippets from Radix submenu to a real Dialog

The submenu refused to open when the parent dropdown was anchored at the
bottom of the window (composer "+" button) — Radix's collision detection +
SubContent positioning was fighting us. Rather than keep tuning side /
sideOffset / collisionPadding / max-h until something stuck, replace the
DropdownMenuSub with a clicked DropdownMenuItem that opens a proper
Dialog.

Side benefits over the submenu:
- Each snippet gets a description line, so a glance is enough to pick one.
- Focus management is handled by Dialog automatically.
- Easy to grow (search, custom user snippets, categories) without
  another round of Radix positioning bugs.

Also extract types/interfaces to the bottom of the file per workspace
convention.

* fix(desktop): move cron 'New cron' button off the top bar into the body

Reverses the previous direction on cron empty-state dedup. The body
button is more discoverable for first-time users (it's anchored next to
the "No scheduled jobs yet" copy that explains the feature) and frees
the top bar from a global CTA that wasn't pulling its weight.

- Empty (zero jobs): EmptyState renders the "Create first cron" button
  again, like the original design.
- Empty (search filtered out all jobs): no button, just "Try a broader
  search query" copy.
- Has jobs: small inline header above the list shows `N/M active` plus
  a single "New cron" button (right-aligned). The rows themselves
  already cover edit/pause/trigger/delete, so this is the only "create"
  affordance.

Also drop the dead `<div className="hidden">…</div>` enabledCount line
the previous patch left behind; the count is now visible in the new
header instead of hidden.

* fix(desktop): address Copilot review on PR 37536

- sessions-settings: guard the WHOLE bridge call rather than chaining
  `?.settings.foo().then(...)` — the latter throws when
  `window.hermesDesktop` is undefined (non-Electron / Vitest contexts)
  because the chain short-circuits to `undefined.then(...)`.
- file_operations: drop `Path.unlink(missing_ok=True)` (Py>=3.8) so the
  generated delete snippet still works on remote backends running
  Python 3.7. The existing FileNotFoundError handler covers the same
  case and works back to 3.4.
- ansi.test.ts: add focused Vitest coverage for the SGR parser
  (basic/bright colors, bold toggles, default-fg reset, coalescing,
  256-color / truecolor arg consumption, non-SGR CSI drop, empty SGR
  full-reset) so future refactors can't silently regress terminal
  rendering.

* fix(desktop/updates): swallow refreshDesktopVersion bridge errors

`refreshDesktopVersion()` is called best-effort with `void` from
`checkUpdates()`, `startUpdatePoller()`, and the window focus handler.
If the IPC bridge rejects (main process shutting down during reload,
bridge not yet ready on first paint), the rejection surfaces as an
unhandled promise rejection in the renderer. Wrap the call in try/catch
and return null on failure so callers can keep the existing
fire-and-forget pattern safely.

* chore(desktop): drop work duplicated by other in-flight PRs

- composer/text-utils.ts: revert paste-image dedupe — PR #37596
  ships the same fix with a cleaner content-key approach and a
  Vitest file (text-utils.test.ts). Letting that PR own the change.
- docs/desktop-i18n-rfc.md: delete the i18n scoping RFC — PR #37568
  has already shipped a working i18n surface (homegrown nanostores
  `t()` helper over en/zh dictionaries), so the RFC's framework
  recommendation (`react-intl`) is now obsolete and would just
  contradict the implementation that's actually landing.

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

Add --include-desktop to the one-line installer and it sets up the agent and builds the desktop app in one go:

curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash -s -- --include-desktop

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

When a release ships desktop installers they're attached to its releases page.dmg (macOS), .exe / .msi (Windows), .AppImage / .deb / .rpm (Linux). These are published manually, so the install-with-Hermes path above is the most reliable way to get the latest.


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). The only thing worth knowing:

  • Windows — the installer bundles its own Git and Python; no admin rights or system changes required.
  • macOS / Linux — uses your system Python 3.11+ (installed automatically if missing).

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 --tui 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.
