Extract the ~16 standalone helpers (message reconciliation, optimistic/resolved
session upserts, stored-session resolution, runtime-info application, error
classification) out of the 1,254-line god hook into a colocated, tested
use-session-actions/utils.ts. index.ts keeps the hook orchestrator (the
stateful action callbacks) and consumes the helpers.
Pure restructuring, no behaviour change; folder index keeps the import path
(`@/app/session/hooks/use-session-actions`) intact. index.ts: 1,254 -> ~950.
Adds unit tests for the pure helpers.
The top-center floating HUDs (command palette + session switcher) pin at
top-3, overlapping the titlebar's `[-webkit-app-region:drag]` bands. Drag
regions win hit-testing over the DOM regardless of z-index, so the top of
each surface — the search input — swallowed clicks, leaving only a ~2px
strip focusable. Add `[-webkit-app-region:no-drag]` to the shared
HUD_SURFACE so the whole surface is interactive.
Finding 2 of the desktop UI-consistency pass. Several surfaces intentionally
make an entire row/cell the click target while hosting nested layout inside a
raw <button> (each re-justifying the pattern in a local comment). Introduce a
zero-style RowButton primitive (components/ui/row-button.tsx) that bakes in the
shared semantics — type="button" + a stable data-slot — without imposing any
styling, then migrate every genuine row-button onto it:
- app/overlays/panel.tsx
- app/artifacts/index.tsx
- app/chat/sidebar/chrome.tsx (SidebarRowBody, SidebarRowLink)
- app/settings/providers-settings.tsx
- components/desktop-onboarding-overlay.tsx (PROVIDER_ROW_CLASS rows)
Fully behavior-preserving: RowButton adds no classes, so each row keeps its
exact layout/look (verified by a unit test asserting className passthrough).
Left as-is (not row-buttons; converting would risk visual regressions): the
compact bespoke buttons in shell/statusbar-controls.tsx (STATUSBAR_ACTION_CLASS,
also a nested DropdownMenuTrigger asChild) and pet-generate/reference-chip.tsx.
Finding 1 of the desktop UI-consistency pass: SVG icon sizing had four
competing conventions with no source of truth. Introduce a named icon-size
scale (iconSize.xs/sm/md/lg/xl -> size-3/3.5/4/5/6) in lib/icons.ts and migrate
the genuine icon deviants onto it:
- desktop-install-overlay.tsx: Loader2/Check/AlertTriangle/Chevron* (h-4 w-4,
h-3.5 w-3.5 -> iconSize.md/sm)
- composer/controls.tsx, voice-activity.tsx, queue-panel.tsx: numeric size={N}
on Tabler icons -> iconSize classes
Sizes snap to the nearest scale step; the only rendered deltas are size={11}
-> 12px (queue/stop glyphs, +1px) and AudioLines size={15} -> 14px (-1px, now
matches its sibling toolbar icons). All other migrations are exact (12/14/16px).
Out of scope (different sizing mechanisms, left untouched): non-icon h-N w-N
layout (sliders, skeletons, swatches), sprite size props (PixelEggSprite), and
Codicon font-icon sizing. Broader size-N -> token adoption is follow-up.
The usePromptActions hook is the textbook "god hook" AGENTS.md warns against.
As a first, safe slice, pull its module-level standalone helpers (no closure
over hook state) into a focused, testable use-prompt-actions-utils.ts sibling:
- error classifiers: isSessionNotFoundError, isSessionBusyError,
isProviderSetupError, inlineErrorMessage
- session-busy retry: withSessionBusyRetry (+ its constants)
- attachment IO: base64FromDataUrl, imageFilenameFromPath,
readImageForRemoteAttach, readFileDataUrlForAttach, friendlyRemoteAttachError
- misc: delay, isSessionIdCandidate, blobToDataUrl, renderCommandsCatalog,
slashStatusText, appendText, visibleUserOrdinal, visibleUserIndexAtOrdinal,
the _submitInFlight guard set, and the GatewayRequest type
Pure restructuring, no behavior change; the usePromptActions and
uploadComposerAttachment exports (and their import paths) are unchanged. Adds
unit tests for the pure helpers. use-prompt-actions.ts: 1,956 -> 1,772.
DesktopController is a route root that had grown a controller's worth of
session-list plumbing inline. Extract the cohesive fetch/paging cluster into
a focused hook and a tested pure helper, per AGENTS.md's "keep route roots
thin" guidance:
- use-session-list-actions.ts: refreshSessions / loadMoreSessions /
loadMoreSessionsForProfile / loadMoreMessagingForPlatform / refreshCronJobs
(plus the private cron/messaging refreshers, sessionsToKeep, and the
excluded-source constants)
- desktop-controller-utils.ts: pure sameCronSignature helper (+ unit tests)
Pure restructuring, no behavior change. desktop-controller.tsx: 1,441 -> 1,233.
Pull ChatBar's module-level pure helpers, constants, and the QueueEditState
type out of the 2.3k-line composer/index.tsx into a focused, testable
composer-utils.ts sibling:
- constants: COMPOSER_STACK_BREAKPOINT_PX, COMPOSER_SINGLE_LINE_MAX_PX,
COMPOSER_FADE_BACKGROUND, DRAFT_PERSIST_DEBOUNCE_MS
- helpers: pickPlaceholder, COMPLETION_ACTIONS, slashChipKindForItem,
slashArgStage, slashCommandToken, cloneAttachments
- type: QueueEditState
Pure restructuring, no behavior change; adds unit tests for the slash helpers.
(The ChatBar component itself is a single tightly-coupled megacomponent; a
deeper hook-based decomposition is left for a dedicated follow-up.)
Behavior-preserving extraction of the 1,942-line thread.tsx transcript
renderer into co-located sibling modules, matching the existing flat
assistant-ui/ convention:
- thread-content.ts / thread-timestamp.ts: pure helpers (+ unit tests)
- thread-types.ts: shared RestoreMessageTarget
- thread-status.tsx: loading / stall / background-resume indicators
- thread-message-parts.tsx: reasoning + tool part components
- assistant-message.tsx, system-message.tsx, user-message.tsx,
user-edit-composer.tsx: the message renderers
thread.tsx now holds only the Thread route component (1,942 -> 119 lines).
Also drops a dead readAloudAudio module variable (no references).
The Cmd-K "Install theme…" palette listed Marketplace themes with no hint
that you already had them, and clicking one re-downloaded + re-installed a
theme you owned. The Appearance settings grid already detected this, but by
parsing theme descriptions inline on every render — plumbing that never made
it to the palette.
Lift it into one reactive source and reuse it everywhere:
- $marketplaceInstalls (computed over $userThemes): extensionId -> installed
theme, derived once via marketplaceIdOf and memoized, instead of rebuilding
a Set per render.
- Both install surfaces now mark owned rows installed and, on click,
re-activate the installed theme rather than re-fetching it.
- Drops the duplicated description-parsing in settings and the per-session
"installed here" state in both surfaces (the store is the source of truth,
so previously-installed themes show correctly too).
DRY: the roomier-side bias computed its probability two ways
(STROLL_TOWARD_ROOM and 1 - STROLL_TOWARD_ROOM). One draw XNOR'd against
the roomier side says the same thing more plainly.
The floating pet wandered almost constantly: every idle beat picked a new
walk and hops fired ~45% of the time, so it read as nervous rather than
alive. Make movement the exception, not the default, and split the
overgrown roam hook into focused modules.
Behavior (per ambient game-AI: GameAIPro ch.36 + idle/wander state
machines):
- Loaf, don't pace: most decision beats just keep resting (REST_CHANCE
0.62) instead of always re-walking.
- Memoryless dwell: pauses now draw from an exponential distribution
(mostly short rests, the occasional long loaf) instead of a uniform
1.8-5.2s window, so the cadence never reads as a metronome.
- Hops dialed back 0.45 -> 0.2 (the jumpiest, noisiest motion).
Structure (no god-file; a hook should own one narrow job):
- roam-behavior.ts - what to do & when (dwellMs, chooseMove,
pickStrollTarget) + tuning. Pure, rng-injectable.
- roam-geometry.ts - where it can stand (snapshotLedges, overlayLedge,
resolveLedge, overlapsX, groundTop). DOM measurement + pure ledge math.
- use-pet-roam.ts - the physics/RAF loop only.
Tests: deterministic, rng-seeded unit coverage for the decision + geometry
helpers (behavior contracts, not snapshots).
When a full-screen route overlay (settings/profiles/cron/agents/command-center) is up, the pet's walkable surface swaps to a single ledge at the overlay card's bottom edge — derived from OverlayView's shared inset, not measured — so it patrols there; closing the overlay restores the normal surfaces and it drops back down.
Walk speed is derived from the sprite's animation loop + on-screen size (one body-width per loop) instead of a fixed px/s, so it steps rather than glides; the pet also sinks a few px so its feet meet the surface instead of hovering.
usePetRoam re-measures ledges from the live DOM each beat and walks/hops/falls between them, driving DOM position imperatively (no per-frame re-render).
Opt-in $petRoam (localStorage), $petMotion (run/jump pose) and $petRoamDir (-1/0/1) feed the shared $petState only while the agent is at rest ($petAtRest), so a wander never overrides real activity.
The Gateway item is the only statusbar entry with variant === 'menu'.
Since da73223f4 wrapped every render branch in `Tip`, the menu branch
nested `<DropdownMenu>` (a Radix Root that renders no DOM node) inside
`Tip`'s `<TooltipTrigger asChild>`. With no element to attach to, Radix
could never wire hover listeners, so the tooltip silently never showed.
`Tip` also can't be moved inside `DropdownMenuTrigger asChild` (the shape
proposed in #54859): it's a plain component, not a Slot-forwarding one, so
the trigger's injected ref/handlers would land on `TooltipContent` instead
of the button and break the menu's click + popper anchoring.
Fix by composing both trigger Slots directly onto a single <button>
(`TooltipTrigger asChild` over `DropdownMenuTrigger asChild`), the pattern
already used in profile-switcher.tsx, and skip the tooltip wrapper entirely
when the item has no title.
Supersedes #54859.

Subagent session pop-outs (`watch=1`) spectate a run driven elsewhere, so
editing/steering the transcript from there makes no sense. Gate the composer
and the user-bubble mutations on `isWatchWindow()`:
- hide the composer (folds into `showChatBar`)
- user prompts become a read-only button that toggles the 2-line clamp so long
prompts stay fully readable, instead of opening the edit composer
- drop the stop/restore actions and the checkpoint branch-picker
Keyed off the narrow `isWatchWindow()` (not `isSecondaryWindow()`), so the
new-session and cmd-click pop-outs are unaffected.
Let users click the status bar context indicator to see how tokens are
split across system prompt, tools, rules, skills, MCP, and conversation.

User terminal tabs and their recent scrollback now survive an app restart
(VS Code parity). Tabs, active selection, cwd, and a serialized scrollback
snapshot are written to localStorage on every change; on launch the tabs
reopen with their history replayed above a fresh shell. Processes are NOT
revived — a new shell starts one line below the restored block.
- Capture: SerializeAddon snapshots the buffer on a 750ms leading-edge
throttle, so a `cmd; quit` lands on disk before teardown; the snapshot is
trimmed of its trailing idle prompt (no "double prompt" on restore) and
capped (200 scrollback lines / 48k chars) to stay under the storage budget.
- Teardown guard: app quit/reload kills the PTYs from the main process,
firing onExit in the renderer, but React skips effect cleanups on teardown
so the per-instance `disposed` flag never flips. A pagehide/beforeunload
flag stops onExit from calling closeTerminal() and wiping the persisted
tabs right before relaunch restores them. A real `exit`/Ctrl-D still closes.
- Agent mirror tabs stay runtime-only — only user tabs persist.
Remove the prompt-gap cleanup that sent Ctrl-L into the user's shell; it could
render as literal ^L and create the exact top-line gap it was meant to hide.
Keep first-prompt cleanup renderer-side only, and parse short ESC charset
sequences so the initial newline stripper does not disarm early.
Also add a Close all action to the terminal tab context menu.
Revert the repo-wide prettier churn the earlier fmt pass pulled into files
unrelated to this work; run prettier/eslint scoped to the touched files only.
- Gateway status popout: flatten the header to stacked connection + inference
statuses with system-panel and restart actions (reusing the shared
runGatewayRestart helper). The recent-activity tail is now live while the
popout is open via the shared LogView (WS connection churn filtered), and the
icon / "View all logs" link dismiss the popover.
- Statusbar "menu" items accept a menuContent(close) render fn over a now
controlled DropdownMenu, so popover content can close itself.
- Drop the always-on gateway-log poll from useStatusSnapshot (logs are fetched
by the popout only while open).
- SearchField → text-xs to match Input/Select (controlVariants).
- Command center: remove the usage/system section dividers, swap the sessions
nav icon (Pin → MessageCircle), small padding tweaks.
The Electron desktop app and the web dashboard each carried their own
copy of the tui_gateway JSON-RPC WebSocket client plus near-identical
auth'd WS-URL construction. The dashboard's copy was the historical
source of the "is the dashboard required to run the desktop app?"
confusion, since the two surfaces looked coupled.
Consolidate the genuinely shared transport into the existing
framework-agnostic `@hermes/shared` package so both surfaces consume it
independently — neither app depends on the other:
- Move `resolveGatewayWsUrl` + `GatewayReauthRequiredError` (single-use
OAuth ticket re-mint vs long-lived token fallback) into
`@hermes/shared`; desktop now imports them directly.
- Add `buildHermesWebSocketUrl`, one base-path/scheme/auth-aware URL
builder, and route every dashboard WS endpoint through it
(`/api/ws`, `/api/events`, `/api/pty`, plugin WS URLs).
- Reduce the dashboard `GatewayClient` to a thin subclass of the shared
`JsonRpcGatewayClient`, deleting ~210 lines of duplicated pending-call
/event-dispatch/connect plumbing while keeping its dashboard-specific
ticket-vs-token auth selection.
- Drop the stale "start it with --tui" chat banner, which implied the
dashboard flag was required.
Behavior is preserved on both surfaces; the dashboard additionally
inherits the shared client's 15s connect timeout (previously
desktop-only), so a hung connect now fails fast instead of pinning the
composer in "connecting".
Register read-only agent terminals with the same renderer-side terminal reader
as user terminals so read_terminal works on whichever tab is active.
Also bring agent xterm rendering closer to user-terminal parity (unicode 11,
web links, font weights/spacing) and make the gateway sink wiring resilient if
only one terminal event sink was already installed.
Make the read-only agent terminal mirrors stream in real time and give
the agent a desktop-only way to dismiss its own tabs.
- Stream background output live: the local reader used a blocking
read(4096) that buffered small periodic output until EOF, so agent
tabs only "filled in" at process exit. Switch to buffer.read1(4096)
(decoded) for incremental chunks.
- Route agent.terminal.output / terminal.close to the window that owns
the process (its gateway session) instead of an empty session id, so
events actually reach the desktop renderer.
- Add close_terminal: a HERMES_DESKTOP-gated tool (sibling of
read_terminal) that drops a process's read-only tab WITHOUT killing it
via process_registry.on_close; output keeps buffering and the user can
reopen from the status stack.
- ⌘W now closes a focused agent tab: mark the agent instance
data-terminal and focus it on activation so isFocusWithin routes there.
- ensureTerminal() no longer spawns an extra user shell when a tab
already exists (e.g. opening a background task from the status stack).
