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.
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.

- Changes panel: a working file opens in a CodeMirror editor with its diff
inline (DiffEditor.tsx, @codemirror/merge, lazy-loaded); Changes folds the
unchanged lines, Whole file shows them; side by side at 50/50 and full
width; a Revert per block; original from HEAD or the branch's merge base
(`mergeBase` on GET /git/changes?range=branch)
- Every diff: green = line added whole, red = removed whole, blue = edited
in place (--diff-mod)
- History drawn as a commit graph (#58: `parents` on GET /git/log,
--date-order; lib/commitGraph.ts)
- Per-workspace never-stage list, drawn orange in the Files tree (--kept);
closed Terminal rows past three deleted
- Status bar plan quota for Claude (per account) and Codex
(GET /api/pricing/quota, server/lib/quota.js); compact hover panel that
stays open, Refresh button with a spinner
- Settings → Appearance holds language, theme and pet; Ctrl+Shift+C copies;
compact sidebar navigation and short session times
- /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.
The session section and the Files/Changes panel drop their cards; one
vertical divider separates them (none at full width), and the collapsed
rail keeps only that divider. The terminal goes back to the page colour
(--surface-0), and the panel's two sticky bars cover scrolled content in
the page colour instead of the card's.
Inside, the git row loses its bordered box for a bottom divider, and the
ended-session prompt box drops its own fill and shadow.
Desktop-parity phase 6, following Claude Desktop:
- the workspace home's Worktree checkbox starts the pane with
`claude --worktree=<name>`, so Claude Code makes, populates
(.worktreeinclude, WorktreeCreate hook) and cleans up
<repo>/.claude/worktrees/<name>; AgentHub only excludes
/.claude/worktrees/ at the repo root (Claude does not)
- server/lib/session-worktree.js resolves a session's worktree from the
session row only (owned by the workspace, registered by git worktree
list); every lane git route takes ?session= and answers ENOWORKTREE
instead of falling back to the main folder
- the session view's Changes panel works in the opened run's worktree
(dashboard_runs.worktree, GitTarget in the client api)
- Resume/Fork start in the session's worktree; a gone one is ENOWORKTREE
- Archive of a worktree session removes the worktree after asking:
git worktree remove without --force, git branch -d (unmerged work keeps
its branch), a lock held by a live pid refused, a stale one cleared
- listWorktrees reads `locked <reason>` locks
- tests scrub GIT_* env so the pre-commit suite cannot act on this repo
- The run form's prompt box offers suggestions again: `/` lists the run
cwd's project and user commands and skills plus the CLI built-ins
(claude lanes only), `@` lists files under the cwd; Enter picks while
the list is open and sends otherwise. The 2f39f4e rewrite had left a
bare textarea that ignored both.
- Active runs lists only the current lane's runs and external sessions
(sessions matched to the lane by longest path-boundary cwd), instead of
every lane's.
- The Changes panel's git line and its actions are one compact row in one
card, and the mode/range toolbar is one wrapping row.
- The lane card hides itself when it has nothing to show, instead of
leaving an empty frame where the git row used to be.
- The branch line, the uncommitted-files hover panel and the git action
row (fetch/pull/push/branch) move from the lane card to the top of the
Changes panel (new LaneGitHeader.tsx); the card has no git row now.
- Header and panel share one git-facts read: stage/unstage/discard/commit
and Refresh re-read it, and a git bar action re-reads the diff, the
history and the file tree.
- The git bar no longer commits: the panel's staged-only box is the one
commit path. Orphaned gitBar.commit*/cancel strings removed (en, vi).
- "New lane here" is wired from Workspace to the panel.
