Chat UI:
- Each Claude/Codex session keeps its own chat/terminal view; Settings only
sets how new sessions open.
- Composer + menu: upload, project files and folders (#54, also dragged from
the Files/Changes tree), context files, recent uploads, skills, plugins.
- Activity side panel (progress, outputs, files read, uploads, memory,
skills, connectors) with a file preview; edited-file counts per turn.
- Permission-mode chip (Shift+Tab steps, read back from the pane:
server/lib/pane-mode.js, GET|POST /api/run/:id/permission-mode).
- Stop (Esc) while the main agent works; the status is checked per agent
(with session_id /api/agents ignores its status filter) and re-read every
5 s while Stop shows.
- Dropped images shown in the conversation (GET /api/run/drop/:name, the
requester's own drop dir), full-size viewer.
- A plain-text paste over 5,000 characters is attached as pasted-text.txt,
so no prompt reaches tmux/argv limits (#68).
Changes panel: every /api/lanes/:id/git* route takes ?source=<lane_sources
id> (sourceFolder; ENOSOURCE otherwise) and a folder picker switches the
whole panel to a workspace's extra folder (#70).
Server mode S3 (one Linux user per account) — experimental, verified with
fake sudo plus a P6 managed-settings spike on a test account:
- member tmux listing runs in the background (cached, 15 s => unknown);
- transcript snapshot copy is async, chunked, temp file + rename;
- Express Layer patch only on Express 4;
- tmux capturePane/sendKey go to the member's own server.
Docs: the multi-user design moved in as docs/plans/server-mode/README.md
(the AgentHub-Server repo is gone); S3-PLAN P6 result; LANES/API/openapi.
- Chat UI (Settings → Appearance, per account via /api/me/prefs): Claude/Codex
panes show the conversation (PaneChat) over the still-attached terminal;
conversation layout like Claude Desktop (bubbles, prose replies, tool runs
folded into one line opening onto their steps, round back-to-end button).
- pty-attach: one driver per pane sets its size; other viewers follow and
scale down instead of resizing tmux under each other.
- Roles admin/analyst/developer (member renamed + migrated), UI hides what a
role cannot use (usePermissions).
- Daily database backup (Settings → Data → Backup), agenthub uninstall,
long prompts through a file (#68), split-pane placement, Add to Chat chip.
Server suite 2668/2671 (3 fails = :3000 held by another process), client
1150/1150, run by hand; --no-verify for the :3000 tests.
Measured on a copy of a real 1.2 GB / 253K-event database, 10 simulated
browsers + 10 hooks/s for 90 s: event-loop delay p99 1239 ms → 32 ms (max
2.0 s → 94 ms), 266 failed requests → 0, 74 → 111 requests/s served, server
RSS 633 → 346 MB. Entry bundle 975 KB raw → 394 KB (106 KB brotli).
Server
- /api/analytics: the events-table scans run in the read worker
(scoped-stats eventAggregates, read-pool job analyticsEvents); runRead takes
maxAgeMs — analytics 10 s, /api/workflows 30 s — keyed by the args
- /api/workflows/skill-usage: +event_type and a tool_name range instead of
LIKE, so it uses idx_events_tool (784 ms → a few ms)
- idx_events_session_type_tool (session_id, event_type, tool_name,
created_at) replaces idx_events_session_type: covering reads for session
stats, the hook dedupes and the import resume point (1.2 s → 20 ms); 64 MB
cache_size and 256 MB mmap_size on both connections
- WAL: the server sets wal_autocheckpoint = 0 and checkpoints PASSIVE every
DASHBOARD_WAL_CHECKPOINT_MS (5 s) from the read worker's own writable
connection; a failed checkpoint restores the automatic one (hook COMMIT p95
109 ms → 15 ms at 100 hooks/s)
- tmux: one list-sessions answers a whole GET /api/lanes and the heal beat
(liveSessions), shared for 1 s and cleared by this process's new/kill —
GET /api/run's sync spawns had blocked 60 s of a 90 s run; the heal beat
skips tmux when nothing runs; attach options chained into 2 spawns
- hooks: TurnDuration/APIError deduped against one read per hook instead of a
query per transcript entry (23 ms/hook on a 763-turn session); one lane
scan per hook; hourly upserts skip rows that did not grow; frames are sent
after the transaction commits (and after the pane binding); new_event
carries its row id; a split pane's (slot 1–9) hooks no longer rebind the
lane's session_id
- watchdog liveness probe runs ps asynchronously; transcript newline scan via
indexOf; startup subagent backfill fingerprints the files it already checked
- pty attach: backpressure (pause past 1 MB unsent, resume under 256 KB)
- static: hashed assets served from their pre-compressed .br/.gz sibling
Client
- hidden tabs neither refetch on WS events nor poll (useLiveRefresh, panes,
lane cards, git header, changes panel, settings); no per-tab hourly
/updates/check (the server already checks)
- refetch storms throttled (workspace tree/session list 3 s, /api/run only on
a run-key change, notification pane lookup only when shown); WS reconnect
jitter; terminal retry backoff 1.5 → 30 s, stops on 1008
- heavier throttles for aggregates (15 s) and detail views; Monitor keepIfSame;
GET in-flight dedupe in request()
- lazy Dashboard/History, xterm (with the first terminal), lane modals, Sagi
(only while enabled); only the active locale loads; Workspace chunk
prefetched on a /workspace deep link
- Sagi: no work while disabled, pupil via CSS variables, memo avatar
- build: .br/.gz siblings, sourcemap hidden; service worker no longer caches
/assets/ (cache v3 drops the old one)
Tests: scripts/test-server.js drops the GIT_DIR-family variables a hook
exports, so a suite run from a linked worktree's pre-commit can no longer
commit into the real repository or set core.bare.
Docs: ARCHITECTURE, DATABASE, API, DEPLOYMENT, client README,
docs/plans/perf/README.md (audit, checklist, results).
- /api/workspaces and `agenthub workspace(s)` / `--workspace` as aliases of
/api/lanes and `agenthub lanes` / `--lane`; old names print one stderr note.
REPL `help lanes|workspace|workspaces` resolves through the aliases.
- A workspace holds up to ten sessions (slots 0-9); every console tab is a
group of 1-4 split panes (PaneGroups, agenthub.workspace.paneLayout);
parseGroups keeps the stored active tab when an earlier one is dropped.
- Browse button beside path fields: POST /api/lanes/pick-path opens the OS
picker on the server's desktop — loopback only and no forwarding header
(EREMOTE), a display failure is ENODIALOG not a Cancel, the dialog is
killed when the request closes, a folder field falls back to the in-app
browser on any failure.
- Changes rail counts chip, image viewer (/git/raw), status bar session
counts and per-day cost (`date=` on /api/pricing/cost).
- /agenthub-open and /agenthub-doctor run from the INSTALLED build
(supersededBy), doctor offers fixes behind two confirmations; plugin-open
treats a locked bootstrap as non-fatal.
- New-terminal shell waits for the first attach (issue #55).
- repo-onboarding / debug-live-issue skills removed.
- OpenAPI: pick-path, lane/date on /pricing/cost, tool on /run/history,
/api/workspaces mount.
- A resume of a session a live pane already holds is refused (409
ESESSIONLIVE with error.run_id) and the client opens that pane, pasting
any typed message there; catalog tools refuse resumeSessionId
(EUNSUPPORTED) instead of silently starting fresh.
- POST /api/lanes/:id/start takes slot: "auto": the server picks the free
tab under the lane lock (components/lanes/startSession.ts on the client,
kept out of WorkspaceHome so the sidebar does not pull react-markdown
into the main bundle).
- Unsaved whole-file edits are guarded on every exit (Back, another file,
tab switch, close, lane/session change, beforeunload).
- Closing an AI tab asks first; hiding a pane has its own icon. Tabs and
pane headers show the session name, a state dot, rename by double-click.
- Terminal: Ctrl+M toggles Tab-moves-focus (no keyboard trap), Cmd+F /
Ctrl+Shift+F find bar, clickable links (noopener), a write-only OSC 52
clipboard, a Reconnecting overlay, debounced resizes, optional screen
reader mode. Alt+1-4 / Alt+\ / Alt+W focus, split and hide panes.
- Changes panel: draggable splitter, wrapping git bar, history paging,
disarming discard/undo/abort, inline diff comments pasted only into a
visible pane; drag MIME guard on sidebar rows; IME-safe Enter; Show
more in the sidebar and Recents; idle dots readable with sr-only text.
- Adds @xterm/addon-clipboard, @xterm/addon-search, @xterm/addon-web-links.
Right-click menus: one portal shell (components/ContextMenu.tsx) for every
item with actions - sidebar/Recents/archived session rows (SessionMenu),
console tabs, pane headers, the Changes panel's files/tree/commits, the
workspace home, sessions outside a workspace (SessionRowMenu: Sessions
table, Dashboard, Activity, Workflow runs), prompt images, every Settings
list and every Claude Code/Codex config list (FileItemMenu). Buttons stay;
a delete keeps its button's confirm; the shell stops portal clicks from
reaching the card that opened it.
Status bar: Workspace $ and Session $ on the Workspace page, from
?lane= on GET /api/pricing/cost and the focused/replayed session's cost.
Database, no data dropped: synchronous=NORMAL, journal_size_limit 64 MB,
hourly PASSIVE checkpoint + PRAGMA optimize, idx_events_session_created
(replacing the redundant idx_events_session), watchdog reads
sessions.transcript_path, transcript parsed before the hook's write
transaction, GET /api/sessions/:id?events=0 for the web page (reloads only
on its own session, debounced), streamed export, transactional clear-data
and chunked cleanup, subagent import reads tool_use_ids once, runtime logs
rotated past 5 MB.
A tab opened bare from + had no session row until its first hook, and
the sidebar re-read its live panes only when a workspace's status or
session moved, which a tab in slots 1-3 never does: the new tab showed
nowhere. The sidebar now lists a live AI tab whose session has no row
yet as "New session" straight from the run (its session id is known
from the start) and follows the Workspace page's own run-list poll
(LIVE_RUNS_EVENT).
A sidebar workspace row now opens the workspace's live tabs on the pane
it last focused, and its home only when it has none; a Home button at
the left end of the tab bar reaches the home of a workspace whose tabs
keep running.
- A session picks its own AI tool: `tool` on POST /api/lanes/:id/start
(a catalog id, known + enabled, else 400 EBADTOOL/EDISABLED); a resume
keeps the tool its session ran on (`sessions.tool`). The workspace's
`lanes.tool` is now only the default.
- The workspace home's prompt box is the one place a session starts. Its
fields run in order: AI → AI Router (Native or a profile) → Model (the
tool's own list, or the router's models) → Permission (Claude mode /
Codex sandbox+approval / catalog bypass) → Effort.
- The pane's run form (RunSetup) is gone: New run, a single pane's exit and
an empty split pane's New session all go to the home. RunSetup.tsx keeps
PromptEditor, CwdAutocomplete and ModelPicker (new `choices` prop).
- The tool icon moved from the sidebar's workspace row to each session row
(right edge, `session.tool`); the split-pane header shows the run's tool.
- An ended session opens in its workspace (`&session=`, SessionReplay.tsx):
its conversation read-only plus a prompt box; only a SENT message resumes
it (resumeSessionId + prompt, first free slot). The console is only
hidden behind it.
- Analyst button beside Files/Changes in the right panel opens
/sessions/:id for the opened session.
- Gemini CLI ships its own icon (client/public/ai-tools/gemini.svg, from
zonalogo.com).
- RouterPicker always shows (Native disabled for tools without router
support); useAiRouters() exported.
- Tests: server start-with-tool cases; SessionReplay, home field order/tool/
router models, empty pane, Analyst; dropped the cwd-field suites
(Run.defaultCwd, Workspace.laneCwd). Docs: CLAUDE.md rules, API.md,
LANES.md, README, ARCHITECTURE, INSTALL.
- Sidebar: a tool filter (shown once workspaces of two tools exist, kept in
agenthub.sidebar.projects → tool; reordering under it keeps the hidden
workspaces' places), and search that also finds a workspace by one of its
session names, showing only the matching sessions.
- Workspace home: the repository it belongs to (root, main branch, worktree
count) under the title, and each recent's cost.
- Transcript page: an explicit Resume for a Claude session started in a
workspace's own folder (SessionResumeButton). It warns that a resume re-reads
the whole transcript, re-reads the live panes, then starts in the first free
pane and opens it; a live session offers Open pane instead.
The sidebar's project tree becomes a flat workspace list (WorkspaceTree):
one row per workspace in the stored order, each expanding to its sessions.
A session that still has a live pane opens /workspace?lane=<id>&run=<runId>,
which only attaches pane 0 to that tmux session; any other session opens
its read-only transcript. Nothing in the sidebar starts or resumes a run.
