Lift the attachment drop engine (dragActive + the 7 drag/drop handlers + the
in-app-ref vs OS-upload split) out of ChatBar into
composer/hooks/use-composer-drop.ts. Self-contained, off the keystroke path —
consumes insertInlineRefs + onAttachDroppedItems + requestMainFocus. Verbatim
move, behaviour-preserving.
Lift the dictation + voice-conversation + auto-speak subsystem out of ChatBar
into composer/hooks/use-composer-voice.ts. It owns voiceConversationActive,
lastSpokenIdRef, the pending-reply readers, submitVoiceTurn, the voice
hooks (recorder/conversation/auto-speak), the Ctrl+B toggle event, and
handleToggleAutoSpeak; it exposes dictate/voiceStatus/voiceActivityState/
conversation/start+endConversation/handleToggleAutoSpeak for the controls.
Self-contained: consumes the draft/submit primitives (insertText, clearDraft,
focusInput, onSubmit) passed in, nothing depends back on it — so unlike the
queue subsystem (which is circularly coupled to the draft helpers) it lifts
cleanly. Behaviour-preserving; verbatim move.
The real composer state-engine fix. ChatBar subscribed to the full draft string
(`useAuiState(s => s.composer.text)`), so every keystroke re-rendered the whole
~2k-line component even though the contentEditable DOM already owns the text.
Replace that with:
- an imperative composer-runtime subscription (useComposerRuntime().subscribe)
that mirrors text into draftRef, repaints the editor ONLY on external changes
(clear/restore/insert; the focused editor is the source otherwise), and drives
the debounced per-session stash — all without a React render. This folds the
old `[draft]` sync effect and the `[draft]` debounced-stash effect into one
place keyed off the runtime, surviving core rebinds via the effect dep.
- coarse edge selectors (hasText / isHelpHint / isSteerableText, plus
isEmpty / hasHardNewline in useComposerMetrics) for the chrome, which only
re-render when an edge actually flips.
Net: typing within a line does zero ChatBar re-renders / style invalidations;
work happens only on real edges. Behaviour-preserving — draftRef + editor are
already kept current by every mutation path; verified by the composer DOM repro
tests (enter-submit, IME composition, slash-nav) + text-guard.
First step of decomposing the ChatBar god component (composer/index.tsx). Pull
the self-contained *sizing* engine — stacked/inline layout + the measured-height
CSS vars the thread reads for clearance — into composer/hooks/use-composer-metrics.ts.
The hook owns: the media-query `narrow`, `expanded`/`tight`, the 8px height
bucketing (so per-keystroke growth never invalidates the tree's computed style),
the ResizeObserver, the popout re-sync, and the CSS-var cleanup. ChatBar now
just calls `useComposerMetrics(...)` and consumes `stacked`.
Behaviour-preserving (no keystroke/IME/contentEditable path touched): code moved
verbatim. Deliberately a low-risk first slice on the app's most fragile file;
the draft/state-engine spine is the next, dogfood-heavy step
(see desktop-composer-plan.md).
Two status-stack icon nits:
- Subagents used `hubot`; switch to the dedicated `agent` codicon.
- The queue section had no icon while every other group (todos, subagents,
background) has one. Give it `layers` (a stack of pending turns), matched to
the group-icon styling so all four sections read consistently.
Preview links (detected HTML files / localhost dev URLs) were rendered as
CHILDREN of the background StatusSection, which is collapsed by default — so the
moment a background task appeared, the previews got swallowed into the collapsed
"N Background" expandable and vanished until you manually expanded it. With no
background group they rendered as a standalone always-visible block, so the bug
only showed once a bg task was running.
Render the preview links as their own always-visible block right after the
background section instead of as collapsible children. They stay visually
associated with the background group (a localhost dev server and its preview are
the same thing) but are no longer hidden by its collapse — a one-tap open is the
whole point.
- Rework share/import into one Dialog (matches rename/create): a single code
field (copy to share, paste + Load to import) with a hover copy button, a
Reset link beside the upload icon when viewing an imported map, and plainer
copy.
- Core orb: scales with the world zoom (~1.25× the inner shell), backdrop wash
behind it; on focus/hover the scene composites above the orb so the active
tooltip + lit lines are never covered.
- fitViewport floors zoom at the reference (5-ring) extent, so big maps render
at a constant scale and pan instead of shrinking every node to fit.
- Light mode: flip inter-ring band shading to read as depth (not a mound),
fade the core ring in from t=0, drop the timeline star glow.
- Timeline: filled play glyph, crisper constellation, date moved into the legend.
After the slash dispatcher, the next-largest body unit was submitPromptText —
a ~280-line submit pipeline. Lift it into a colocated useSubmitPrompt sub-hook
(use-prompt-actions/submit.ts) with a typed SubmitPromptDeps object; body moves
verbatim. SubmitTextOptions moves to utils.ts (shared by submit + submitText).
Pure restructuring, no behaviour change (full use-prompt-actions suite green).
index.ts: 1,212 -> 937.
The remaining bulk of useMessageStream was handleGatewayEvent — a ~550-line
event-type dispatcher. Lift it into a colocated useGatewayEventHandler sub-hook
(use-message-stream/gateway-event.ts): the values it closed over (sibling
streaming callbacks + the 3 stable refs the deps array omitted + options)
become a typed GatewayEventDeps object; the dispatcher body moves verbatim.
Pure restructuring, no behaviour change (utils tests still green). index.ts:
1,120 -> 540.
The usePromptActions body's largest unit was executeSlashCommand — a ~530-line
`/command` dispatcher. Lift it into a colocated useSlashCommand sub-hook
(use-prompt-actions/slash.ts): the ~13 values it closed over become a typed
SlashCommandDeps object the parent passes in; the dispatcher body (and its inner
runSlash recursion) moves verbatim. SlashActionCtx (slash-only) moves with it.
Pure restructuring, no behaviour change (verified: full use-prompt-actions test
suite still green). index.ts: 1,772 -> ~1,250.
Extract the standalone gateway-event helpers (session-info patch derivation,
completion-error detection, todo-payload routing, delegate_task -> subagent
spec mapping, + the stream-flush/subagent-event constants) out of the
1,285-line hook into a colocated, tested use-message-stream/utils.ts. index.ts
keeps the stateful streaming hook and consumes the helpers.
Pure restructuring, no behaviour change; folder index keeps the import path
intact. index.ts: 1,285 -> ~1,120. Adds unit tests for the pure helpers.
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.
Within each ring band, split the time-ordered nodes into a few sub-bursts
(~5 nodes each) that share an ignite moment, with a touch of per-node jitter.
The build-up reads as clustered pops instead of a constant single-file trickle
(or an all-at-once flood).
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.
Extract the copy-pasted "re-resolve on theme repaint" MutationObserver into a
shared hooks/use-theme-epoch (useThemeEpoch + onThemeRepaint) and consume it
from the star map, image-gen placeholder, and useIsDark instead of each hand-
rolling its own root observer. Keeps the post-paint read the canvas probes need
(useTheme() would read stale CSS — child effects run before applyTheme).
Also: light-mode band depth (inner wash), travelling-glow core scramble, and
dark-only timeline bloom.
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.
Revert the helix coil to the constellation scatter, biased toward the
midline (triangular vertical), and stop a packed core ring from crushing
every quieter bucket into one invisible speck: sqrt-scale the per-bucket
star count, floor star size to 2px, and lift the dim baseline.
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.
- Sprite-atlas the orbs: render each (ink, sheen, darken) appearance once,
blit it per node, instead of allocating a radial gradient every frame.
- Split paint into a cached static layer + a live core scramble; the heavy
scene only re-renders on real change, so an idle map costs a scramble +
one drawImage rather than a full redraw.
- Pause the render loop while the window is hidden/blurred; resume on focus.
- Make the scramble's glyph count data-independent (constant cells to the
rim, clamped size) so it's the same field on any graph; size tracks zoom.
- Size nodes against the rested fit (fitScale), held stable through
playback's spore-zoom — so t≈0 no longer balloons orbs into bubbles.
- Wind the timeline constellation along a helix for depth.
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).
A top-down Memory Graph panel: memories and skills on a radial time axis
(core = oldest, outer rings = newer) with a playable / scrubbable timeline
that builds the map up over time.
- Reveal lives off the React tree (a ref drives the canvas, a nanostore atom
drives the timeline + legend), so a play-through or scrub never re-renders
the panel; paint is coalesced to one rAF and playback is abortable, so even
frantic scrubbing stays responsive.
- Adaptive dated rings: one equal-width ring per POPULATED calendar bucket,
a "nice-tick" count scaled to the span. Constant (orthographic) core/band
scale — more data grows the disk outward (more rings), never thinner.
- A bucket's nodes fill the band inside their ring and ignite staggered by
real timestamp across it (no end-dump), with an EVE-style warp-in; the
camera steps out band-by-band as rings are reached.
- ASCII "computing" core, theme-aware palette with a distinct memory hue,
shared trackpad-gesture primitives.
- Shareable WoW-style "loadout" codes on a generic, reusable codec
(@/lib/loadout: bitstream + DEFLATE + version/checksum frame + base64url).
- Opens from the statusbar and command palette; i18n across all locales.
Deps: d3-force, fflate (drops unused react-force-graph-2d).
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.
