Inline diff segments were anchored relative to assistant narration, but the
turn details pane still rendered after streamSegments. On completion that put
the diff before the tool telemetry that produced it. When a turn has anchored
diff segments, commit the accumulated thinking/tool trail as a pre-diff trail
message, then render the diff and final summary.
Tolerating null top-level keys silently drops user settings (e.g.
`agent.system_prompt` next to a bare `agent:` line is gone). Probe at
session create, log via `logger.warning`, and surface in the boot info
under `config_warning` — rendered in the TUI feed alongside the existing
`credential_warning` banner.
Exposes hermes --tui over a PTY-backed WebSocket so the dashboard can
embed the real TUI rather than reimplement its surface. The browser
attaches xterm.js to the socket; keystrokes flow in, PTY output bytes
flow out.

│ onData ───► ws.send(keystrokes)
│ onResize ► ws.send('\x1b[RESIZE:cols;rows]')
│ write ◄── ws.onmessage (PTY bytes)

PtyBridge (ptyprocess) ── spawns node ui-tui/dist/entry.js ──► tui_gateway + AIAgent
Components
----------
hermes_cli/pty_bridge.py
Thin wrapper around ptyprocess.PtyProcess: byte-safe read/write on the
master fd via os.read/os.write (not PtyProcessUnicode — ANSI is
inherently byte-oriented and UTF-8 boundaries may land mid-read),
non-blocking select-based reads, TIOCSWINSZ resize, idempotent
SIGHUP→SIGTERM→SIGKILL teardown, platform guard (POSIX-only; Windows
is WSL-supported only).
hermes_cli/web_server.py
@app.websocket("/api/pty") endpoint gated by the existing
_SESSION_TOKEN (via ?token= query param since browsers can't set
Authorization on WS upgrades). Loopback-only enforcement. Reader task
uses run_in_executor to pump PTY bytes without blocking the event
loop. Writer loop intercepts a custom \x1b[RESIZE:cols;rows] escape
before forwarding to the PTY. The endpoint resolves the TUI argv
through a _resolve_chat_argv hook so tests can inject fake commands
without building the real TUI.
Tests
-----
tests/hermes_cli/test_pty_bridge.py — 12 unit tests: spawn, stdout,
stdin round-trip, EOF, resize (via TIOCSWINSZ + tput readback), close
idempotency, cwd, env forwarding, unavailable-platform error.
tests/hermes_cli/test_web_server.py — TestPtyWebSocket adds 7 tests:
missing/bad token rejection (close code 4401), stdout streaming,
stdin round-trip, resize escape forwarding, unavailable-platform ANSI
error frame + 1011 close, resume parameter forwarding to argv.
96 tests pass under scripts/run_tests.sh.

feat(web): add Chat tab with xterm.js terminal + Sessions resume button
(cherry picked from commit 3d21aee8 by emozilla, conflicts resolved
against current main: BUILTIN_ROUTES table + plugin slot layout)
fix(tui): replace OSC 52 jargon in /copy confirmation
When the user ran /copy successfully, Ink confirmed with:
sent OSC52 copy sequence (terminal support required)
That reads like a protocol spec to everyone who isn't a terminal
implementer. The caveat was a historical artifact — OSC 52 wasn't
universally supported when this message was written, so the TUI
honestly couldn't guarantee the copy had landed anywhere.
Today every modern terminal (including the dashboard's embedded
xterm.js) handles OSC 52 reliably. Say what the user actually wants
to know — that it copied, and how much — matching the message the
TUI already uses for selection copy:
copied 1482 chars
(cherry picked from commit a0701b1d5a)
docs: document the dashboard Chat tab
AGENTS.md — new subsection under TUI Architecture explaining that the
dashboard embeds the real hermes --tui rather than rewriting it,
with pointers to the pty_bridge + WebSocket endpoint and the rule
'never add a parallel chat surface in React.'
website/docs/user-guide/features/web-dashboard.md — user-facing Chat
section inside the existing Web Dashboard page, covering how it works
(WebSocket + PTY + xterm.js), the Sessions-page resume flow, and
prerequisites (Node.js, ptyprocess, POSIX kernel / WSL on Windows).
(cherry picked from commit 2c2e32cc45)
feat(tui-gateway): transport-aware dispatch + WebSocket sidecar
Decouples the JSON-RPC dispatcher from its I/O sink so the same handler
surface can drive multiple transports concurrently. The PTY chat tab
already speaks to the TUI binary as bytes — this adds a structured
event channel alongside it for dashboard-side React widgets that need
typed events (tool.start/complete, model picker state, slash catalog)
that PTY can't surface.
- `tui_gateway/transport.py` — `Transport` protocol + `contextvars` binding
+ module-level `StdioTransport` fallback. The stdio stream resolves
through a lambda so existing tests that monkey-patch `_real_stdout`
keep passing without modification.
- `tui_gateway/ws.py` — WebSocket transport implementation; FastAPI
endpoint mounting lives in hermes_cli/web_server.py.
- `tui_gateway/server.py`:
- `write_json` routes via session transport (for async events) →
contextvar transport (for in-request writes) → stdio fallback.
- `dispatch(req, transport=None)` binds the transport for the request
lifetime and propagates it to pool workers via `contextvars.copy_context`
so async handlers don't lose their sink.
- `_init_session` and the manual-session create path stash the
request's transport so out-of-band events (subagent.complete, etc.)
fan out to the right peer.
`tui_gateway.entry` (Ink's stdio handshake) is unchanged externally —
it falls through every precedence step into the stdio fallback, byte-
identical to the previous behaviour.
feat(web): ChatSidebar — JSON-RPC sidecar next to xterm.js terminal
Composes the two transports into a single Chat tab:
┌─────────────────────────────────────────┬──────────────┐
│ xterm.js / PTY (emozilla #13379) │ ChatSidebar │
│ the literal hermes --tui process │ /api/ws │
└─────────────────────────────────────────┴──────────────┘
terminal bytes structured events
The terminal pane stays the canonical chat surface — full TUI fidelity,
slash commands, model picker, mouse, skin engine, wide chars all paint
inside the terminal. The sidebar opens a parallel JSON-RPC WebSocket
to the same gateway and renders metadata that PTY can't surface to
React chrome:
• model + provider badge with connection state (click → switch)
• running tool-call list (driven by tool.start / tool.progress /
tool.complete events)
• model picker dialog (gateway-driven, reuses ModelPickerDialog)
The sidecar is best-effort. If the WS can't connect (older gateway,
network hiccup, missing token) the terminal pane keeps working
unimpaired — sidebar just shows the connection-state badge in the
appropriate tone.
- `web/src/components/ChatSidebar.tsx` — new component (~270 lines).
Owns its GatewayClient, drives the model picker through
`slash.exec`, fans tool events into a capped tool list.
- `web/src/pages/ChatPage.tsx` — split layout: terminal pane
(`flex-1`) + sidebar (`w-80`, `lg+` only).
- `hermes_cli/web_server.py` — mount `/api/ws` (token + loopback
guards mirror /api/pty), delegate to `tui_gateway.ws.handle_ws`.

refactor(web): /clean pass on ChatSidebar + ChatPage lint debt
- ChatSidebar: lift gw out of useRef into a useMemo derived from a
reconnect counter. React 19's react-hooks/refs and react-hooks/
set-state-in-effect rules both fire when you touch a ref during
render or call setState from inside a useEffect body. The
counter-derived gw is the canonical pattern for "external resource
that needs to be replaceable on user action" — re-creating the
client comes from bumping `version`, the effect just wires + tears
down. Drops the imperative `gwRef.current = …` reassign in
reconnect, drops the truthy ref guard in JSX. modelLabel +
banner inlined as derived locals (one-off useMemo was overkill).
- ChatPage: lazy-init the banner state from the missing-token check
so the effect body doesn't have to setState on first run. Drops
the unused react-hooks/exhaustive-deps eslint-disable. Adds a
scoped no-control-regex disable on the SGR mouse parser regex
(the \\x1b is intentional for xterm escape sequences).
All my-touched files now lint clean. Remaining warnings on web/
belong to pre-existing files this PR doesn't touch.
Verified: vitest 249/249, ui-tui eslint clean, web tsc clean,
python imports clean.
chore: uptick
fix(web): drop ChatSidebar tool list — events can't cross PTY/WS boundary
The /api/pty endpoint spawns `hermes --tui` as a child process with its
own tui_gateway and _sessions dict; /api/ws runs handle_ws in-process in
the dashboard server with a separate _sessions dict. Tool events fire on
the child's gateway and never reach the WS sidecar, so the sidebar's
tool.start/progress/complete listeners always observed an empty list.
Drop the misleading list (and the now-orphaned ToolCall primitive),
keep model badge + connection state + model picker + error banner —
those work because they're sidecar-local concerns. Surfacing tool calls
in the sidebar requires cross-process forwarding (PTY child opens a
back-WS to the dashboard, gateway tees emits onto stdio + sidecar
transport) — proper feature for a follow-up.
feat(web): wire ChatSidebar tool list to PTY child via /api/pub broadcast
The dashboard's /api/pty spawns hermes --tui as a child process; tool
events fire in the python tui_gateway grandchild and never crossed the
process boundary into the in-process WS sidecar — so the sidebar tool
list was always empty.
Cross-process forwarding:
- tui_gateway: TeeTransport (transport.py) + WsPublisherTransport
(event_publisher.py, sync websockets client). entry.py installs the
tee on _stdio_transport when HERMES_TUI_SIDECAR_URL is set, mirroring
every dispatcher emit to a back-WS without disturbing Ink's stdio
handshake.
- hermes_cli/web_server.py: new /api/pub (publisher) + /api/events
(subscriber) endpoints with a per-channel registry. /api/pty now
accepts ?channel= and propagates the sidecar URL via env. start_server
also stashes app.state.bound_port so the URL is constructable.
- web/src/pages/ChatPage.tsx: generates a channel UUID per mount,
passes it to /api/pty and as a prop to ChatSidebar.
- web/src/components/ChatSidebar.tsx: opens /api/events?channel=, fans
tool.start/progress/complete back into the ToolCall list. Restores
the ToolCall primitive.
Tests: 4 new TestPtyWebSocket cases cover channel propagation,
broadcast fan-out, and missing-channel rejection (10 PTY tests pass,
120 web_server tests overall).
fix(web): address Copilot review on #14890
Five threads, all real:
- gatewayClient.ts: register `message`/`close` listeners BEFORE awaiting
the open handshake. Server emits `gateway.ready` immediately after
accept, so a listener attached after the open promise could race past
the initial skin payload and lose it.
- ChatSidebar.tsx: wire `error`/`close` on the /api/events subscriber
WS into the existing error banner. 4401/4403 (auth/loopback reject)
surface as a "reload the page" message; mid-stream drops surface as
"events feed disconnected" with the existing reconnect button. Clean
unmount closes (1000/1001) stay silent.
- web-dashboard.md: install hint was `pip install hermes-agent[web]` but
ptyprocess lives in the `pty` extra, not `web`. Switch to
`hermes-agent[web,pty]` in both prerequisite blocks.
- AGENTS.md: previous "never add a parallel React chat surface" guidance
was overbroad and contradicted this PR's sidebar. Tightened to forbid
re-implementing the transcript/composer/PTY terminal while explicitly
allowing structured supporting widgets (sidebar / model picker /
inspectors), matching the actual architecture.
- web/package-lock.json: regenerated cleanly so the wterm sibling
workspace paths (extraneous machine-local entries) stop polluting CI.
Tests: 249/249 vitest, 10/10 PTY/events, web tsc clean.
refactor(web): /clean pass on ChatSidebar events handler
Spotted in the round-2 review:
- Banner flashed on clean unmount: `ws.close()` from the effect cleanup
fires `close` with code 1005, opened=true, neither 1000 nor 1001 —
hit the "unexpected drop" branch. Track `unmounting` in the effect
scope and gate the banner through a `surface()` helper so cleanup
closes stay silent.
- DRY the duplicated "events feed disconnected" string into a local
const used by both the error and close handlers.
- Drop the `opened` flag (no longer needed once the unmount guard is
the source of truth for "is this an expected close?").
Copilot review on #14968 caught that the early returns gated on the
global `detailsMode === 'hidden'` short-circuited every render path
before sectionMode() got a chance to apply per-section overrides — so
`details_mode: hidden` + `sections.tools: expanded` was silently a no-op.
Three call sites had the same bug shape; all now key off the resolved
section modes:
- ToolTrail: replace the `detailsMode === 'hidden'` early return with
an `allHidden = every section resolved to hidden` check. When that's
true, fall back to the floating-alert backstop (errors/warnings) so
quiet-mode users aren't blind to ambient failures, and update the
comment block to match the actual condition.
- messageLine.tsx: drop the same `detailsMode === 'hidden'` pre-check
on `msg.kind === 'trail'`; only skip rendering the wrapper when every
section resolves to hidden (`SECTION_NAMES.some(...) !== 'hidden'`).
- useMainApp.ts: rebuild `showProgressArea` around `anyPanelVisible`
instead of branching on the global mode. This also fixes the
suppressed Copilot concern about an empty wrapper Box rendering above
the streaming area when ToolTrail returns null.
Regression test in details.test.ts pins the override-escapes-hidden
behaviour for tools/thinking/activity. 271/271 vitest, lints clean.
- domain/details: extract `norm()`, fold parseDetailsMode + resolveSections
into terser functional form, reject array values for resolveSections
- slash /details: destructure tokens, factor reset/mode into one dispatch,
drop DETAIL_MODES set + DetailsMode/SectionName imports (parseDetailsMode
+ isSectionName narrow + return), centralize usage strings
- ToolTrail: collapse 4 separate xxxSection vars into one memoized
`visible` map; effect deps stabilize on the memo identity instead of
4 primitives
Rebase-artefact cleanup on this branch:
- Restore `voice.status` and `voice.transcript` cases in
createGatewayEventHandler plus the `voice` / `submission` /
`composer.setInput` ctx destructuring. They were added to main in
the 58-commit gap that this branch was originally cut behind;
dropping them was unintentional.
- Rebase the test ctx shape to match main (voice.* fakes,
submission.submitRef, composer.setInput) and apply the same
segment-anchor test rewrites on top.
- Drop the `#14XXX` placeholder from the tool.complete comment;
replace with a plain-English rationale.
- Rewrite the broken mid-word "pushInlineDiff- Segment" in
turnController's dedupe comment to refer to
pushInlineDiffSegment and `kind: 'diff'` plainly.
- Collapse the filter predicate in recordMessageComplete from a
4-line if/return into one boolean expression — same semantics,
reads left-to-right as a single predicate.
Copilot review threads resolved: #3134668789, #3134668805,
#3134668822.
Visual polish on top of the segment-anchor change: diff blocks were
butting up against the narration around them. Tag diff-only segments
with `kind: 'diff'` (extended on Msg) and give them `marginTop={1}` +
`marginBottom={1}` in MessageLine, matching the spacing we already
use for user messages. Also swaps the regex-based `diffSegmentBody`
check for an explicit `kind === 'diff'` guard so the dedupe path is
clearer.
Revisits #13729. That PR buffered each `tool.complete`'s inline_diff
and merged them into the final assistant message body as a fenced
```diff block. The merge-at-end placement reads as "the agent wrote
this after the summary", even when the edit fired mid-turn — which
is both misleading and (per blitz feedback) feels like noise tacked
onto the end of every task.
Segment-anchored placement instead:
- On tool.complete with inline_diff, `pushInlineDiffSegment` calls
`flushStreamingSegment` first (so any in-progress narration lands
as its own segment), then pushes the ```diff block as its own
segment into segmentMessages. The diff is now anchored BETWEEN the
narration that preceded the edit and whatever the agent streams
afterwards, which is where the edit actually happened.
- `recordMessageComplete` no longer merges buffered diffs. The only
remaining dedupe is "drop diff-only segments whose body the final
assistant text narrates verbatim (or whose diff fence the final
text already contains)" — same tradeoff as before, kept so an
agent that narrates its own diff doesn't render two stacked copies.
- Drops `pendingInlineDiffs` and `queueInlineDiff` — buffer + end-
merge machinery is gone; segmentMessages is now the only source
of truth.
Side benefit: Ctrl+C interrupt (`interruptTurn`) iterates
segmentMessages, so diff segments are now preserved in the
transcript when the user cancels after an edit. Previously the
pending buffer was silently dropped on interrupt.
Reported by Teknium during blitz usage: "no diffs are ever at the
end because it didn't make this file edit after the final message".
TTS feedback loop (hermes_cli/voice.py)
The VAD loop kept the microphone live while speak_text played the
agent's reply over the speakers, so the reply itself was picked up,
transcribed, and submitted — the agent then replied to its own echo
("Ha, looks like we're in a loop").
Ported cli.py:_voice_tts_done synchronisation:
- _tts_playing: threading.Event (initially set = "not playing").
- speak_text cancels the active recorder before opening the speakers,
clears _tts_playing, and on exit waits 300 ms before re-starting the
recorder — long enough for the OS audio device to settle so afplay
and sounddevice don't race for it.
- _continuous_on_silence now waits on _tts_playing (up to 60 s) before
re-arming the mic with another 300 ms gap, mirroring
cli.py:10619-10621. If the user flips voice off during the wait the
loop exits cleanly instead of fighting for the device.
Without both halves the loop races: if the silence callback fires
before TTS starts it re-arms immediately; if TTS is already playing
the pause-and-resume path catches it.
Red REC badge (ui-tui appChrome + useMainApp)
Classic CLI (cli.py:_get_voice_status_fragments) renders "● REC" in
red and "◉ STT" in amber. TUI was showing a dim "REC" with no dot,
making it hard to spot at a glance. voiceLabel now emits the same
glyphs and appChrome colours them via t.color.error / t.color.warn,
falling back to dim for the idle label.
Three issues surfaced during end-to-end testing of the CLI-parity voice
loop and are fixed together because they all blocked "speak → agent
responds → TTS reads it back" from working at all:
1. Wrong result key (hermes_cli/voice.py)
transcribe_recording() returns {"success": bool, "transcript": str},
matching cli.py:_voice_stop_and_transcribe. The wrapper was reading
result.get("text"), which is None, so every successful Groq / local
STT response was thrown away and the 3-strikes halt fired after
three silent-looking cycles. Fixed by reading "transcript" and also
honouring "success" like the CLI does. Updated the loop simulation
tests to return the correct shape.
2. TTS speak-back was missing (tui_gateway/server.py + hermes_cli/voice.py)
The TUI had a voice.toggle "tts" subcommand but nothing downstream
actually read the flag — agent replies never spoke. Mirrored
cli.py:8747-8754's dispatch: on message.complete with status ==
"complete", if _voice_tts_enabled() is true, spawn a daemon thread
running speak_text(response). Rewrote speak_text as a full port of
cli.py:_voice_speak_response — same markdown-strip regex pipeline
(code blocks, links, bold/italic, inline code, headers, list bullets,
horizontal rules, excessive newlines), same 4000-char cap, same
explicit mp3 output path, same MP3-over-OGG playback choice (afplay
misbehaves on OGG), same cleanup of both extensions. Keeps TUI TTS
audible output byte-for-byte identical to the classic CLI.
3. Auto-submit swallowed on non-empty composer (createGatewayEventHandler.ts)
The voice.transcript handler branched on prev input via a setInput
updater and fired submitRef.current inside the updater when prev was
empty. React strict mode double-invokes state updaters, which would
queue the submit twice; and when the composer had any content the
transcript was merely appended — the agent never saw it. CLI
_pending_input.put(transcript) unconditionally feeds the transcript
as the next turn, so match that: always clear the composer and
setTimeout(() => submitRef.current(text), 0) outside any updater.
Side effect can't run twice this way, and a half-typed draft on the
rare occasion is a fair trade vs. silently dropping the turn.
Also added peak_rms to the rec.stop debug line so "recording too quiet"
is diagnosable at a glance when HERMES_VOICE_DEBUG=1.
The TUI had drifted from the CLI's voice model in two ways:
- /voice on was lighting up the microphone immediately and Ctrl+B was
interpreted as a mode toggle. The CLI separates the two: /voice on
just flips the umbrella bit, recording only starts once the user
presses Ctrl+B, which also sets _voice_continuous so the VAD loop
auto-restarts until the user presses Ctrl+B again or three silent
cycles pass.
- /voice tts was missing entirely, so users couldn't turn agent reply
speech on/off from inside the TUI.
This commit brings the TUI to parity.
Python
- hermes_cli/voice.py: continuous-mode API (start_continuous,
stop_continuous, is_continuous_active) layered on the existing PTT
wrappers. The silence callback transcribes, fires on_transcript,
tracks consecutive no-speech cycles, and auto-restarts — mirroring
cli.py:_voice_stop_and_transcribe + _restart_recording.
- tui_gateway/server.py:
- voice.toggle now supports on / off / tts / status. The umbrella
bit lives in HERMES_VOICE + display.voice_enabled; tts lives in
HERMES_VOICE_TTS + display.voice_tts. /voice off also tears down
any active continuous loop so a toggle-off really releases the
microphone.
- voice.record start/stop now drives start_continuous/stop_continuous.
start is refused with a clear error when the mode is off, matching
cli.py:handle_voice_record's early return on `not _voice_mode`.
- New voice.transcript / voice.status events emit through
_voice_emit (remembers the sid that last enabled the mode so
events land in the right session).
TypeScript
- gatewayTypes.ts: voice.status + voice.transcript event
discriminants; VoiceToggleResponse gains tts; VoiceRecordResponse
gains status for the new "started/stopped" responses.
- interfaces.ts: GatewayEventHandlerContext gains composer.setInput +
submission.submitRef + voice.{setRecording, setProcessing,
setVoiceEnabled}; InputHandlerContext.voice gains enabled +
setVoiceEnabled for the mode-aware Ctrl+B handler.
- createGatewayEventHandler.ts: voice.status drives REC/STT badges;
voice.transcript auto-submits when the composer is empty (CLI
_pending_input.put parity) and appends when a draft is in flight.
no_speech_limit flips voice off + sys line.
- useInputHandlers.ts: Ctrl+B now calls voice.record (start/stop),
not voice.toggle, and nudges the user with a sys line when the
mode is off instead of silently flipping it on.
- useMainApp.ts: wires the new event-handler context fields.
- slash/commands/session.ts: /voice handles on / off / tts / status
with CLI-matching output ("voice: mode on · tts off").
Backward compat preserved for voice.record (was always PTT shape;
gateway still honours start/stop with mode-gating added).
When the user runs /voice and then presses Ctrl+B in the TUI, three
handlers collaborate to consume the chord and none of them dispatch
voice.record:
- isAction() is platform-aware — on macOS it requires Cmd (meta/super),
so Ctrl+B fails the match in useInputHandlers and never triggers
voiceStart/voiceStop.
- TextInput's Ctrl+B pass-through list doesn't include 'b', so the
keystroke falls through to the wordMod backward-word branch on Linux
and to the printable-char insertion branch on macOS — the latter is
exactly what timmie reported ("enters a b into the tui").
- /voice emits "voice: on" with no hint, so the user has no way to
know Ctrl+B is the recording toggle.
Introduces isVoiceToggleKey(key, ch) in lib/platform.ts that matches
raw Ctrl+B on every platform (mirrors tips.py and config.yaml's
voice.record_key default) and additionally accepts Cmd+B on macOS so
existing muscle memory keeps working. Wires it into useInputHandlers,
adds Ctrl+B to TextInput's pass-through list so the global handler
actually receives the chord, and appends "press Ctrl+B to record" to
the /voice on message.
Empirically verified with hermes --tui: Ctrl+B no longer leaks 'b'
into the composer and now dispatches the voice.record RPC (the
downstream ImportError for hermes_cli.voice is a separate upstream
bug — follow-up patch).
Trim comment noise, remove redundant typing, normalize sticky prompt viewport args to top→bottom order, and reuse one sticky viewport helper instead of duplicating the math.
When the viewport is away from the bottom, keep the last visible progress snapshot instead of rebuilding the streaming/thinking subtree on every turn-store update. This cuts scroll-time churn while preserving live updates near the tail and on turn completion.
- appLayout.tsx: restore the 1-row placeholder when `showStickyPrompt`
is false. Dropping it saved a row but the composer height shifted by
one as the prompt appeared/disappeared, jumping the input vertically
on scroll.
- useInputHandlers: gateway.rpc (from useMainApp) already catches errors
with its own sys() message and resolves to null. The previous `.catch`
was dead code and on RPC failures the user saw both 'error: ...' (from
rpc) and 'failed to toggle yolo'. Drop the catch and gate 'failed to
toggle yolo' on a non-null response so null (= rpc already spoke)
stays silent.
- normalizeStatusBar: replace Set + early-returns + cast with a single
alias lookup table. Handles legacy `false`, trims/lowercases strings,
maps `on` → `top` in one pass. One expression, no `as` hacks.
- Tab title block: drop the narrative comment, fold
blockedOnInput/titleStatus/cwdTag/terminalTitle into inline expressions
inside useTerminalTitle. Avoids shadowing the outer `cwd`.
- tui_gateway statusbar set branch: read `display` once instead of
`cfg0.get("display")` twice.
Previously the terminal tab title was `{⏳/✓} {model} — Hermes` which
only distinguished busy vs idle. Users juggling multiple Hermes tabs had
no way to tell which one was waiting on them for approval/clarify/sudo/
secret, and no cue for which workspace the tab was attached to.
- 3-state marker: `⚠` when an overlay prompt is open, `⏳` busy, `✓` idle.
- Append `· {shortCwd}` (28-char budget, $HOME → ~) so the tab surfaces
the workspace directly.
- Drop the `— Hermes` suffix — the marker already signals what this is,
and tab titles are tight.
Copilot on #14145 flagged that the shift+tab yolo handler treated any
non-null RPC result as valid, so a response shape like {value: undefined}
or {value: 'weird'} would incorrectly echo 'yolo off'. Now only '1' and
'0' map to on/off; anything else (including missing value) surfaces as
'failed to toggle yolo', matching the null/catch branches.
- normalizeStatusBar: trim/lowercase + 'on' → 'top' alias so user-edited
YAML variants (Top, " bottom ", on) coerce correctly
- shift-tab yolo: no-op with sys note when no live session; success-gated
echo and catch fallback so RPC failures don't report as 'yolo off'
- tui_gateway config.set/get statusbar: isinstance(display, dict) guards
mirroring the compact branch so a malformed display scalar in config.yaml
can't raise
Tests: +1 vitest for trim/case/on, +2 pytest for non-dict display survival.
- normalizeStatusBar collapses to one ternary expression
- /statusbar slash hoists the toggle value and flattens the branch tree
- shift-tab yolo comment reduced to one line
- cursorLayout/offsetFromPosition lose paragraph-length comments
- appLayout collapses the three {!overlay.agents && …} into one fragment
- StatusRule drops redundant flexShrink={0} (Yoga default)
- server.py uses a walrus + frozenset and trims the compat helper
Net -43 LoC. 237 vitest + 46 pytest green, layouts unchanged.
'top' and 'bottom' are positions relative to the input row, not the alt
screen viewport:
- top (default) → inline above the input, where the bar originally lived
(what 'on' used to mean)
- bottom → below the input, pinned to the last row
- off → hidden
Drops the literal top-of-screen placement; 'on' is kept as a backward-
compat alias that resolves to 'top' at both the config layer
(normalizeStatusBar, _coerce_statusbar) and the slash command.
Default is back to 'on' (inline, above the input) — bottom was too far
from the input and felt disconnected. Users who want it pinned can
opt in explicitly.
- UiState.statusBar: boolean → 'on' | 'off' | 'bottom' | 'top'
- /statusbar [on|off|bottom|top|toggle]; no-arg still binary-toggles
between off and on (preserves muscle memory)
- appLayout renders StatusRulePane in three slots (inline inside
ComposerPane for 'on', above transcript row for 'top', after
ComposerPane for 'bottom'); only the slot matching ui.statusBar
actually mounts
- drop the input's marginBottom when 'bottom' so the rule sits tight
against the input instead of floating a row below
- useConfigSync.normalizeStatusBar coerces legacy bool (true→on,
false→off) and unknown shapes to 'on' for forward-compat reads
- tui_gateway: split compact from statusbar config handlers; persist
string enum with _coerce_statusbar helper for legacy bool configs
- input wrap: add <Text wrap="wrap-char"> mode that drives wrap-ansi with
wordWrap:false, and align cursorLayout/offsetFromPosition to that same
boundary (w=cols, trailing-cell overflow). Word-wrap's whitespace
reshuffle was causing the cursor to jump a word left/right on each
keystroke near the right edge — blitz row 9
- shift-tab: toggle per-session yolo without submitting a turn (mirrors
Claude Code's in-place dangerously-approve); slash /yolo still works
for discoverability — blitz row 5 sub-item 11
- statusline: lift StatusRule out of ComposerPane to a new StatusRulePane
anchored at the bottom of AppLayout, below the input — blitz row 5
sub-item 12
Pull duplicated rules into ui-tui/src/lib/subagentTree so the live overlay,
disk snapshot label, and diff pane all speak one dialect:
- export fmtDuration(seconds) — was a private helper in subagentTree;
agentsOverlay's local secLabel/fmtDur/fmtElapsedLabel now wrap the same
core (with UI-only empty-string policy).
- export topLevelSubagents(items) — matches buildSubagentTree's orphan
semantics (no parent OR parent not in snapshot). Replaces three hand-
rolled copies across createGatewayEventHandler (disk label), agentsOverlay
DiffPane, and prior inline filters.
Also collapse agentsOverlay boilerplate:
- replace IIFE title + inner `delta` helper with straight expressions;
- introduce module-level diffMetricLine for replay-diff rows;
- tighten OverlayScrollbar (single thumbColor expression, vBar/thumbBody).
Adds unit coverage for the new exports (fmtDuration + topLevelSubagents).
No behaviour change; 221 tests pass.
- delegate_task: use shared tool_error() for the paused-spawn early return
so the error envelope matches the rest of the tool.
- Disk snapshot label: treat orphaned nodes (parentId missing from the
snapshot) as top-level, matching buildSubagentTree / summarizeLabel.
Four real issues Copilot flagged:
1. delegate_tool: `_build_child_agent` never passed `toolsets` to the
progress callback, so the event payload's `toolsets` field (wired
through every layer) was always empty and the overlay's toolsets
row never populated. Thread `child_toolsets` through.
2. event handler: the race-protection on subagent.spawn_requested /
subagent.start only preserved `completed`, so a late-arriving queued
event could clobber `failed` / `interrupted` too. Preserve any
terminal status (`completed | failed | interrupted`).
3. SpawnHud: comment claimed concurrency was approximated by "widest
level in the tree" but code used `totals.activeCount` (total across
all parents). `max_concurrent_children` is a per-parent cap, so
activeCount over-warns for multi-orchestrator runs. Switch to
`max(widthByDepth(tree))`; the label now reads `⚡W/cap+extra` where
W is the widest level (drives the ratio) and `+extra` is the rest.
4. spawn_tree.list: comment said "peek header without parsing full list"
but the code json.loads()'d every snapshot. Adds a per-session
`_index.jsonl` sidecar written on save; list() reads only the index
(with a full-scan fallback for pre-index sessions). O(1) per
snapshot now vs O(file-size).
- createGatewayEventHandler: remove dead `return` after a block that
always returns (tool.complete case). The inner block exits via
both branches so the outer statement was never reachable. Was
pre-existing on main; fixed here because it was the only thing
blocking `npm run fix` on this branch.
- agentsOverlay + ops: prettier reformatting.
`npm run fix` / `npm run type-check` / `npm test` all clean.
Adds a live + post-hoc audit surface for recursive delegate_task fan-out.
None of cc/oc/oclaw tackle nested subagent trees inside an Ink overlay;
this ships a view-switched dashboard that handles arbitrary depth + width.
Python
- delegate_tool: every subagent event now carries subagent_id, parent_id,
depth, model, tool_count; subagent.complete also ships input/output/
reasoning tokens, cost, api_calls, files_read/files_written, and a
tail of tool-call outputs
- delegate_tool: new subagent.spawn_requested event + _active_subagents
registry so the overlay can kill a branch by id and pause new spawns
- tui_gateway: new RPCs delegation.status, delegation.pause,
subagent.interrupt, spawn_tree.save/list/load (disk under
\$HERMES_HOME/spawn-trees/<session>/<ts>.json)
TUI
- /agents overlay: full-width list mode (gantt strip + row picker) and
Enter-to-drill full-width scrollable detail mode; inverse+amber
selection, heat-coloured branch markers, wall-clock gantt with tick
ruler, per-branch rollups
- Detail pane: collapsible accordions (Budget, Files, Tool calls, Output,
Progress, Summary); open-state persists across agents + mode switches
via a shared atom
- /replay [N|last|list|load <path>] for in-memory + disk history;
/replay-diff <a> <b> for side-by-side tree comparison
- Status-bar SpawnHud warns as depth/concurrency approaches caps;
overlay auto-follows the just-finished turn onto history[1]
- Theme: bump DARK dim #B8860B → #CC9B1F for readable secondary text
globally; keep LIGHT untouched
Tests: +29 new subagentTree unit tests; 215/215 passing.
Restore the old-CLI contract where only complete failures tint Activity
red. Everything else is still visible for debugging but no longer
commandeers attention.
- gateway.stderr: always tone='info' (drops the ERRLIKE_RE regex)
- gateway.protocol_error: both pushes demoted to 'info'
- commands.catalog cold-start failure: demoted to 'info'
- approval.request: no longer duplicates the overlay into Activity
Kept as 'error': terminal `error` event, gateway.start_timeout,
gateway-exited, explicit status.update kinds.
After the prior inline-diff fix, the gateway still prepends a literal
" ┊ review diff" line to inline_diff (it's terminal chrome written by
`_emit_inline_diff`). Wrapping that in a ```diff fence left that header
inside the code block. The agent also often narrates its own edit in a
second fenced diff, so the assistant message ended up stacking two
diff blocks for the same change.
- Strip the leading "┊ review diff" header from queued inline diffs
before fencing.
- Skip appending the fenced diff entirely when the assistant already
wrote its own ```diff (or ```patch) fence.
Keeps the single-surface diff UX even when the agent is chatty.
When tool.complete already carries inline_diff, the assistant message owns the full diff block. Suppress the tool-row summary/detail in that case so the turn shows one detailed diff surface instead of a rich diff plus a duplicated tool-detail payload.
Avoid duplicate diff rendering in #13729 flow. We now skip queued inline diffs that are already present in final assistant text and dedupe repeated queued diffs by exact content.
Follow-up for #13729: segment-level system artifacts still looked detached in real flow.\n\nInstead of appending inline_diff as a standalone segment/system row, queue sanitized diffs during tool.complete and append them as a fenced diff block to the assistant completion text on message.complete. This keeps the diff in the same message flow as the assistant response.
Follow-up on multiline arrow behavior: Up/Down now fall back to queue/history whenever there is no logical line above/below the caret (not only at absolute start/end character positions). This makes Up from the end of the top line cycle history, matching expected readline-ish behavior.
Follow-up on #13729 from blitz screenshot feedback.\n\n- When tool.complete carried inline_diff but no buffered assistant text existed, pending tool rows were still in streamPendingTools, so diff rendered above the tool row section. appendSegmentMessage now emits pending tool rows as a trail segment before appending the diff artifact.\n- Strip ANSI color escapes from inline_diff payloads so we don't render loud red/green terminal palettes in the transcript.
Follow-up on #13726 from blitz feedback: Up/Down history cycling should only trigger when the caret is at the start/end boundary (or the input is empty).\n\nPreviously useInputHandlers intercepted arrows whenever inputBuf was empty, which still stole Up/Down from normal multiline editing. textInput now publishes caret position through inputSelectionStore even with no active selection, and useInputHandlers gates history/queue cycling on those boundaries.
Reported during TUI v2 blitz retest: code-review diffs from tool.complete
appeared at the top of the current interaction thread, out of sequence
with the agent's messages and tool rows below them.
Root cause — `sys(inline_diff)` appends to `historyItems`, which sits
above the `StreamingAssistant` pane that renders the active turn.
Until the turn closed, the diff visually floated above everything
else happening in the same turn.
Route the diff through `turnController.appendSegmentMessage` instead
so it flushes any pending streaming text first, then lands in the
segment stream beside assistant output and tool calls. On
`message.complete` the segment list is committed to history in emit
order (diff → final text), matching what the gateway sent.
Adds a regression test that exercises tool.complete → message.complete
with an inline_diff payload and asserts both the streaming and final
placement.
Reported during TUI v2 blitz retest: `/history` in the TUI only shows
prompts from non-TUI Hermes runs and can't scroll the window. Root
cause is the slash-worker subprocess: it's a detached HermesCLI that
never sees the TUI's turns, so its `conversation_history` starts empty
and `show_history` surfaces whatever was persisted from earlier CLI
sessions — not what the user just did inside the TUI.
Intercept `/history` as a local slash command so it dumps
`ctx.local.getHistoryItems()` — the TUI's own transcript — routed
through the pager (which scrolls after #13591). Accepts an optional
preview-length argument (default 400 chars per message).
Adds createSlashHandler coverage.
Two bugs that allow dangerous commands to execute without informed user consent.
TUI (Ink): useInputHandlers consumes the isBlocked return path, but Ink's
EventEmitter delivers keystrokes to ALL registered useInput listeners. The
ApprovalPrompt component receives arrow keys, number keys, and Enter even
though the overlay appears frozen. The user sees no visual feedback, but
keystrokes are processed — allowing blind approval, session-wide auto-approve
(choice "session"), or permanent allowlist writes (choice "always") without
the user knowing.
Discovered while replicating #13618 (TUI approval overlay freezes terminal).
Fix: in useInputHandlers, when overlay.approval/clarify/confirm is active,
only intercept Ctrl+C. All other keys pass through. This makes the overlay
visually responsive so the user can see what they are selecting.
CLI (prompt_toolkit): _callback_tls in terminal_tool.py is threading.local().
set_approval_callback() is called in the main thread during run(), but the
agent executes in a background thread. _get_approval_callback() returns None
in the agent thread, falling back to stdin input() which prompt_toolkit
blocks. The user sees the approval text but cannot respond — the terminal is
unusable until the 60s timeout expires with a default "deny".
Fix: set callbacks inside run_agent() (the thread target), matching the
pattern already used by acp_adapter/server.py. Clear on thread exit to avoid
stale references.
Closes#13618
interruptTurn only flushed the in-flight streaming chunk (bufRef) to
the transcript before calling idle(), which wiped segmentMessages and
pendingSegmentTools. Every tool call and commentary line the agent had
already emitted in the current turn disappeared the moment the user
cancelled, even though that output is exactly what they want to keep
when they hit Ctrl+C (quote from the blitz feedback: "everything was
fine up until the point where you wanted to push to main").
Append each flushed segment message to the transcript first, then
render the in-flight partial with the `*[interrupted]*` marker and its
pendingSegmentTools. Sys-level "interrupted" note still fires when
there is nothing to preserve.
The pager overlay backing /history, /toolsets, /help and any paged slash
output only advanced with Enter/Space and closed at the end. Could not
scroll back, scroll line-by-line, or jump to endpoints.
Adds Up/Down (↑↓, j/k), PgUp (b), g/G for top/bottom, keeps existing
Enter/Space/PgDn forward-and-auto-close, and clamps offset so
over-scrolling past the last page is a no-op.
