* feat(web,hub,cli): show machine load in session sidebar Runners attach OS health snapshots to machine-alive heartbeats; the hub caches them and the web session list renders load or CPU between the machine label and session count. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web,cli): show CPU and RAM pressure in machine health badge Sidebar label now combines CPU and RAM percentages for overload signaling; load stays in the tooltip on Unix. Prime CPU sampling so the first heartbeat includes usage, not just memory. Co-authored-by: Cursor <cursoragent@cursor.com> * feat(web): visual machine health meters with tooltip Replace bare CPU/RAM text with labeled mini bar gauges, chip border tint by severity, and a HoverTooltip explaining capacity and overload guidance. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web): widen machine health tooltip with horizontal layout Allow a generous popover width and lay CPU/RAM/load out side by side so the capacity tooltip reads wider and less tall than the chip. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web): anchor machine health tooltip to row left edge Wide tooltip was align=end on the chip, so it grew left off-screen. Use row-span positioning on the machine tile button instead. Co-authored-by: Cursor <cursoragent@cursor.com> * feat(web): machine host card with OS label and inline health Turn the session sidebar machine row into a bordered host panel with OS metadata and side-by-side CPU/RAM meters embedded in the tile instead of a flat label line matching project rows. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web): keep machine host tile single-row height Collapse the machine header back to one py-1.5 row with OS and compact inline health beside the name, and restore the original project indent without the extra nested rail or second header line. Co-authored-by: Cursor <cursoragent@cursor.com> * feat(web): show CPU core count in machine health tooltip When the runner reports cpuCount, the tooltip reads "CPU across all 6 cores" instead of the generic all-cores label. Co-authored-by: Cursor <cursoragent@cursor.com> * docs: add machine health sidebar screenshots Dogfood captures for the session sidebar machine tile and capacity tooltip, for upstream PR review. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(cli): clear machine-alive priming timeout on disconnect Track the 50ms CPU priming setTimeout and clear it in stopKeepAlive so disconnect/shutdown during the delay cannot leave a stray interval alive. Co-authored-by: Cursor <cursoragent@cursor.com> * chore: drop dogfood screenshots from upstream PR diff Review evidence lives in the PR discussion only; no need to ship PNGs in the repo long-term. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web): truncate long machine OS/host metadata in sidebar row Bound the metadata span so a long hostname cannot push the health chip or session count off-screen in narrow sidebars. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web): reveal machine health tooltip on keyboard row focus Wire MACHINE_ROW_TOOLTIP_FOCUS_CLASS and aria-describedby on the machine header button so keyboard users can read the health tooltip like session rows. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(cli): use MemAvailable for Linux RAM pressure on Bun Bun's os.freemem() reflects MemFree (~1% on cache-heavy hosts), which made sidebar RAM read ~99% while btop showed ~40% used. Parse /proc/meminfo MemAvailable instead so used percent matches operator tools. Co-authored-by: Cursor <cursoragent@cursor.com> * feat(web,cli): show machine uptime in sidebar tiles and tooltip Collect os.uptime() as uptimeSeconds on keepalive and render compact up 1h 54m in the machine meta row plus an Uptime line in the health tooltip. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web): anchor machine health tooltip to chip not row align=row positioned the tooltip below the full machine header button, so the collapsible project panel painted over it on hover. Use align=end with a min-width panel so mouse and keyboard tooltips stay visible. Co-authored-by: Cursor <cursoragent@cursor.com> --------- Co-authored-by: Cursor <cursoragent@cursor.com>
hapi-web
React Mini App / PWA for monitoring and controlling hapi sessions.
What it does
- Session list with status, pending approvals, todos, and summaries.
- Chat view with streaming updates and message sending.
- Permission approval and denial workflows.
- Permission mode and model selection.
- Machine list and remote session spawn.
- File browser and git status/diff views.
- PWA install prompt and offline banner.
Runtime behavior
- When opened inside Telegram, auth uses Telegram WebApp init data.
- When opened in a normal browser, you can log in with
CLI_API_TOKEN:<namespace>(orCLI_API_TOKENfor the default namespace). - The login screen includes a top-right hub picker; if unset, the app uses the same origin it was loaded from.
- Live updates come from the hub via SSE.
Routes
See src/router.tsx for route definitions.
/- Redirect to /sessions./sessions- Session list./sessions/$sessionId- Chat interface./sessions/new- Create new session./sessions/$sessionId/files- File browser with git status./sessions/$sessionId/file- File viewer with diff support./sessions/$sessionId/terminal- Terminal interface./settings- Application settings.
Features
Session list (src/components/SessionList.tsx)
- Active/inactive status indicator.
- Session title from name, summary, or path.
- Todo progress display.
- Pending permission request count.
- Agent flavor label (claude/codex/gemini).
- Model mode display.
Chat interface (src/components/SessionChat.tsx)
- Message thread with infinite scroll.
- Composer for sending messages.
- Permission mode toggle (default/acceptEdits/auto/bypassPermissions/plan).
- Model selection (default/sonnet/sonnet[1m]/opus/opus[1m]).
- Session abort and mode switch controls.
- Context size display.
- Per-session scratchlist (
src/components/AssistantChat/ScratchlistPanel.tsx)- Workbench panel for held notes/drafts; distinct from the queue.
- Add/delete/reorder entries; promote to composer (copy) or queue (send).
- Persists across reloads via
localStoragekeyed per session. - Keyboard shortcut: Ctrl/Cmd+Shift+S to focus the add-input.

- File search with ripgrep.
- Navigate to file viewer.
File viewer (src/routes/sessions/file.tsx)

Voice assistant
- ElevenLabs integration (@elevenlabs/react)
- Real-time voice control
New session (src/components/NewSession/)
Modular session creation:

- Directory input with recent paths
- Agent type selector
- Model selector
- Permission mode toggle (YOLO mode)
Authentication
See src/hooks/useAuth.ts and src/hooks/useAuthSource.ts.
- Telegram Mini App: Uses initData from WebApp SDK.
- Browser: Uses CLI_API_TOKEN from login prompt.
- JWT tokens with auto-refresh.
Data fetching
See src/hooks/queries/ for query hooks and src/hooks/mutations/ for mutations.
- Sessions, messages, machines via TanStack Query.
- Git status and file operations.
- Optimistic updates for message sending.
Real-time updates
See src/hooks/useSSE.ts.
- SSE connection to
/api/events. - Session/message/machine update events.
- Automatic cache invalidation on events.

Development
From the repo root:
bun install
bun run dev:web
If testing in Telegram, set:
HAPI_PUBLIC_URLto the public HTTPS URL of the dev server.CORS_ORIGINSto include the dev server origin.
Tests
Unit tests run under vitest + jsdom:
bun run test:web
End-to-end browser tests for the scratchlist component (real Chromium, real
inert focus blocking, real localStorage round-trips) live at the repo root
under e2e/:
bun run test:e2e # headless
bun run test:e2e:ui # Playwright UI mode (debug)
The spec drives a Vite-served fixture page (web/e2e-fixtures/scratchlist-fixture.html)
that mounts the production ScratchlistPanel in isolation, so no hub /
auth / socket setup is required.
Build
bun run build:web
The built assets land in web/dist and are served by hapi-hub. The single executable can embed these assets.
Standalone hosting
You can host web/dist on a static host (GitHub Pages, Cloudflare Pages) and point it at any hapi hub:
- Build the web app. If your static host uses a subpath, set the Vite base:
bun run build:web -- --base /<repo>/
- Deploy
web/distto your static host. - Set hub CORS to allow the static origin (
HAPI_PUBLIC_URLorCORS_ORIGINS). - Open the static site, click the top-right Hub button on the login screen, and enter the hapi hub origin.
Clear the hub override in the same dialog to return to same-origin behavior.
