* fix(tui): honor documented mouse_tracking config key
The TUI runtime was reading display.tui_mouse while docs and user-facing
examples pointed users at display.mouse_tracking. That made persistent
mouse-disable config look like a no-op for users trying to restore native
terminal selection/copy behavior on Linux/SSH/tmux terminals.
Use display.mouse_tracking as the canonical key, keep display.tui_mouse as
a legacy fallback, and have /mouse write the documented key. Both gateway
config.get and client-side config sync now share the same precedence: the
canonical key wins, then the legacy key, then default on.
* review(copilot): align mouse tracking config coercion
- Load gateway config once before deriving display.mouse_tracking state.
- Use key-presence precedence on the TUI client too, so canonical
mouse_tracking wins over legacy tui_mouse even when the value is null.
- Treat numeric 0 as disabled on both gateway and client, matching the
existing string "0" handling.
- Widen ConfigDisplayConfig mouse fields because config.get full returns raw
YAML, not normalized booleans.
This PR groups the TUI fixes that restore macOS Terminal usability and clean up the theme/composer regressions:
- copy transcript selections on macOS drag-release so Terminal.app users can copy while mouse tracking is enabled
- copy composer selections on macOS drag-release; composer selection is internal to TextInput and does not use the global Ink selection bus
- keep IDE Cmd+C forwarding setup macOS-only, and make keybinding conflict checks respect simple when-clause overlap/negation
- force truecolor before chalk initializes (unless NO_COLOR / FORCE_COLOR / HERMES_TUI_TRUECOLOR opt-outs apply) so the default banner keeps its gold/amber/bronze gradient in Terminal.app
- move TUI surfaces onto semantic theme tokens and preserve skin prompt symbols as bare tokens with renderer-owned spacing
- render focused placeholders as dim hint text in TTY mode instead of inverse/selected-looking synthetic cursor text
* feat(tui): pluggable busy-indicator styles (kaomoji/emoji/unicode/ascii)
The status-bar `FaceTicker` rotated through wide-and-variable kaomoji
glyphs (`(｡•́︿•̀｡)`, `( ͡° ͜ʖ ͡°)`, …) every 2.5s. Real display widths range
from ~5 to ~16 columns, so the rest of the bar (cwd, ctx %, voice,
bg counter) shifted on every cycle. Padding the verb alone (#17116)
helped but didn't address the dominant jitter source — the glyph
itself.
Add four indicator styles, configurable + hot-swappable:
* `kaomoji` (default — preserves the existing vibe; verb is now
pad-stable so the only width churn left is the kaomoji itself).
* `emoji` — single 2-col emoji frame (`⚕ 🌀🤔✨🍵🔮`).
* `unicode` — `unicode-animations` braille spinner (1-col, smooth).
* `ascii` — `| / - \` (1-col, max compat).
Wires:
* `display.tui_status_indicator` in `DEFAULT_CONFIG` (default
`kaomoji`).
* New JSON-RPC `config.set/get indicator` keys, narrow allow-list.
* `applyDisplay` reads the field and patches `UiState.indicatorStyle`,
so the existing `mtime` poll picks up `~/.hermes/config.yaml` edits
within ~5s without a TUI restart.
* `/indicator [style]` slash command (alias `/indicator-style`,
subcommand completion `kaomoji|emoji|unicode|ascii`). Bare form
shows the current style; setter fires `config.set` and
optimistically `patchUiState({ indicatorStyle })` so the live TUI
swaps immediately, matching the `/skin` UX.
* `CommandDef("indicator", ..., subcommands=...)` so classic CLI
autocomplete + TUI `complete.slash` both surface it.
* `FaceTicker` decouples spinner cadence from verb cadence — the
glyph runs at the spinner's authored interval (or `FACE_TICK_MS`
for kaomoji), the verb stays on the original 2.5s cycle, and both
re-arm cleanly when style changes.
Tests:
* `normalizeIndicatorStyle` rejects unknown / non-string input.
* `applyDisplay → tui_status_indicator` covers fan-out + fallback.
* `/indicator <style>` hot-swaps `UiState.indicatorStyle` after a
successful `config.set`.
* `/indicator sparkle` rejects with the usage hint and never hits
the gateway.
* Slash-parity matrix gets `'/indicator'` → `config.get`.
Validation:
cd ui-tui && npm run type-check — clean; npm test --run — 398/398.
scripts/run_tests.sh tests/test_tui_gateway_server.py
tests/hermes_cli/test_commands.py — 220/220.
* chore(tui): drop /indicator-style alias to declutter autocomplete
* fix(tui): drop verb-width pad — /indicator handles glyph jitter directly
* fix(tui): unicode indicator style hides the verb (cleanest option)
* refactor(tui): single source of truth for INDICATOR_STYLES; cleaner error format
Round 1 Copilot review on PR #17150:
- Exported `INDICATOR_STYLES` const tuple from `interfaces.ts`;
`IndicatorStyle` union type is derived from it. `useConfigSync`
builds its validation Set from the tuple, and `session.ts` uses it
for both the usage hint and the runtime allow-list — adding/removing
a style now touches one line.
- Backend `config.set indicator` error message: switched
`sorted(allowed)` list repr to `pick one of ascii|emoji|kaomoji|unicode`
(matches the TUI usage hint), and reports the normalized `raw`
instead of the original `value`. Backend allowed tuple now has a
comment pointing back at `INDICATOR_STYLES` so the two stay aligned.
Note: kept the verb portion unpadded per design intent — fixed-width
padding was the exact UX the `/indicator` command was added to remove.
Stable width comes from the glyph; verbs cycling is part of the kawaii
aesthetic. Reply on the verb thread will explain.
* fix(tui): drop type collapse + gate verb timer + DEFAULT_INDICATOR_STYLE
Round 2 Copilot review on PR #17150:
- `tui_status_indicator?: 'ascii' | ... | string` collapses to `string`
in TS — consumers got no narrowing. Documented as plain `string` with
a comment about runtime validation via `normalizeIndicatorStyle`.
- `FaceTicker` always started a 2.5s verb interval, even for the
`unicode` style which hides the verb entirely. Now gated on
`showVerb` from `renderIndicator` — `unicode` stays calm.
Pre-emptive self-review (avoid round 3):
- Three call sites duplicated the literal `'kaomoji'` default
(uiStore, normalizeIndicatorStyle, slash command). Added
`DEFAULT_INDICATOR_STYLE` to interfaces.ts and threaded it through
so changing the default touches one line.
* fix(tui-gateway): normalize config.get indicator output to match TUI render
Round 4 Copilot review on PR #17150: `config.get` for `indicator`
returned the raw `display.tui_status_indicator` value without
validation, so a hand-edited config.yaml with stray casing or an
unknown style would leave `/indicator` printing one thing while
the TUI rendered the kaomoji default (frontend's
`normalizeIndicatorStyle` does this normalization on receive).
Lifted the allow-list to module scope as `_INDICATOR_STYLES` /
`_INDICATOR_DEFAULT`, reused by both `config.set` and `config.get`.
Comment notes the alignment with `INDICATOR_STYLES` /
`DEFAULT_INDICATOR_STYLE` in interfaces.ts so adding/removing a
style is a one-line change on each end.
Tests cover: known value verbatim, casing/whitespace normalize,
unknown→default, unset→default.
* fix(tui-gateway): preserve falsy-input diagnostics in config.set indicator error
Round 5 Copilot review on PR #17150: `raw = str(value or "").strip().lower()`
collapsed any falsy non-string (`0`, `False`, `[]`) to empty string,
so the error message read `unknown indicator: ` with nothing after —
losing the original input.
Switched to `("" if value is None else str(value)).strip().lower()`
so only `None` (the genuine 'no value' case) becomes blank. Used
`{raw!r}` in the error so the diagnostic is unambiguous (`'0'` vs `0`).
Tests:
- known-value happy path (`'EMOJI'` → `'emoji'`)
- falsy non-string inputs (`0` / `False` / `[]`) surface meaningfully
- `None` keeps the blank-repr error
* feat(tui): expand light-terminal auto-detection (HERMES_TUI_THEME, BG hex)
Modern terminals (Ghostty, Warp, iTerm2) don't set COLORFGBG, so the
auto-light path was effectively COLORFGBG-only and silently broken for
many users. Two pragmatic additions, both opt-in, plus a clearer
priority chain:
1. **`HERMES_TUI_THEME=light|dark`** as a symmetric explicit override.
The existing `HERMES_TUI_LIGHT` is fine but reads as boolean noise;
a named theme env var matches `display.skin` muscle memory.
2. **`HERMES_TUI_BACKGROUND` hex/rgb hint.** Lets advanced users
(or a future OSC11 query helper that caches the answer) state a
ground-truth background colour. Decoded to Rec. 709 luma; ≥ 0.6
counts as light.
Priority order is now fully ordered and explainable:
1. `HERMES_TUI_LIGHT` (1/0/true/false/on/off).
2. `HERMES_TUI_THEME=light|dark`.
3. `HERMES_TUI_BACKGROUND` luminance.
4. `COLORFGBG` last field — light slots 7/15 → light, 0–15 → dark
(authoritative when set, so the new TERM_PROGRAM path can never
stomp on a terminal that already volunteered a dark answer).
5. `TERM_PROGRAM` allow-list — empty by default. The slot is left
in place because folks asked for it but populating it risks
wrongly flipping users on Apple_Terminal / iTerm2 dark profiles
to light. Easy to add per terminal once we have signal.
Tests: 5 new cases in `theme.test.ts` covering theme env, background
hex (3- and 6-char), invalid hex falling through, and COLORFGBG taking
precedence over the future allow-list.
Validation: `npm run type-check` clean, `npm test --run` 392/392.
* review(copilot): tighten theme detection comments + drop unnecessary cast
* review(copilot): strict hex regex so partial garbage doesn't slip into luminance
* test(tui): make TERM_PROGRAM allow-list injectable so precedence is provable
Copilot review on PR #17113: `LIGHT_DEFAULT_TERM_PROGRAMS` is empty
in production, so the prior assertion would have passed even if
`detectLightMode` ignored `COLORFGBG` entirely. That defeats the
test's purpose.
`detectLightMode` now takes the allow-list as an optional second
argument (defaults to the production set). The test injects a set
containing `Apple_Terminal`, asserts the allow-list alone WOULD
return light, then asserts `COLORFGBG: '15;0'` overrides it — the
precedence rule is now exercised, not assumed.
* fix(tui): COLORFGBG empty-trailing-field falls through; isolate DEFAULT_THEME tests
Round 2 Copilot review on PR #17113:
1. `Number(colorfgbg.split(';').at(-1))` returns 0 for an empty trailing
field (e.g. `COLORFGBG='15;'` → bg===0), which would have looked
like an authoritative dark slot and incorrectly blocked the
TERM_PROGRAM allow-list. Added a `/^\d+$/` guard before coercion;
non-numeric trailing fields now fall through.
2. Fixed the misleading '0–6 / 8–15 ranges are dark' comment — the
block returns true for bg===15, so the range is actually 0–6 / 8–14.
3. `DEFAULT_THEME` is computed from `process.env` at module-load.
A developer shell with `HERMES_TUI_THEME=light` (or a bright
`HERMES_TUI_BACKGROUND`) would flip it and break local tests.
The DEFAULT_THEME describe blocks now sterilize the relevant env
vars + dynamically import theme.ts (vi.resetModules pattern from
platform.test.ts). fromSkin tests compare against DARK_THEME
directly to decouple them from ambient env.
* test(tui): isolate ALL env-coupled theme symbols, not just DEFAULT_THEME
Round 3 Copilot review on PR #17113: the static top-level imports of
`fromSkin`, `DARK_THEME`, `LIGHT_THEME` evaluated theme.ts before
`importThemeWithCleanEnv` had a chance to clean the env. Because
`fromSkin` closes over `DEFAULT_THEME`, an ambient `HERMES_TUI_THEME=light`
or bright `HERMES_TUI_BACKGROUND` would still flip the base palette
and cause local-only failures.
Removed the static import entirely. Every test now obtains its theme
symbols via `importThemeWithCleanEnv`, including `detectLightMode`
(for consistency, even though it takes env as a parameter).
`fromSkin` tests assert against the cleaned `DEFAULT_THEME` from the
same dynamic import — preserves the actual contract (skins extend the
ambient base palette) without coupling the test to dev-shell state.
Verified by running with HERMES_TUI_THEME=light + HERMES_TUI_BACKGROUND=#ffffff:
all 20 theme tests still pass.
Self-review (avoid round 4):
- Audited other test files importing DEFAULT_THEME (syntax.test.ts,
streamingMarkdown.test.ts, constants.test.ts) — all just pass it as
a parameter or assert palette property existence (works on both
light + dark), so no env coupling there.
* fix(tui): honor display.busy_input_mode in TUI v2
The TUI v2 frontend hard-coded `composerActions.enqueue(full)` whenever
`ui.busy` was true. The classic CLI and gateway adapters honor the
`display.busy_input_mode` config key (`interrupt` | `queue` | `steer`),
but Ink ignored it — sending a message during a long-running turn always
landed in the queue regardless of config. The config default is already
`interrupt` (hermes_cli/config.py), so users who explicitly opted into
that experience were silently stuck on the legacy queue path.
This wires the value through the existing config-sync surface:
* `applyDisplay` now reads `display.busy_input_mode`, defaults to
`interrupt` (matching `_load_busy_input_mode` in tui_gateway), and
drops it into a new `UiState.busyInputMode` field.
* `dispatchSubmission` and the queue-edit fall-through call a shared
`handleBusyInput` helper that branches on the mode:
* `queue` — legacy behavior, append to the queue.
* `steer` — call `session.steer`; on rejection, fall back to
queue with a sys note.
* `interrupt` — `turnController.interruptTurn(...)` then `send()`,
so the new prompt actually moves.
* Mtime polling in `useConfigSync` already re-applies `config.full`, so
flipping `display.busy_input_mode` in `~/.hermes/config.yaml` takes
effect on the next 5s tick without restarting the TUI.
Tests:
* `applyDisplay → busy_input_mode` covers normalization + UiState fan-out.
* `normalizeBusyInputMode` mirrors the Python side's allow-list.
Validation:
* `npm run type-check` (in `ui-tui/`) — clean.
* `npm test --run` (in `ui-tui/`) — 394/394.
* review(copilot): narrow busy_input_mode type, preserve queue order on steer fallback
* review(copilot): clarify handleBusyInput comment (option, not return value)
* fix(tui): default busy_input_mode to queue in TUI (CLI keeps interrupt)
In a full-screen TUI users typically author the next prompt while the
agent is still streaming, so an unintended interrupt loses in-flight
typing. TUI fallback now defaults to `queue`; CLI / messaging
adapters keep `interrupt` as the framework default.
Override per-config via `display.busy_input_mode: interrupt` (or
`steer`) — the normalize/wire path is unchanged, only the missing-
value branch differs from the Python default.
uiStore initial value also flipped to `queue` so first-frame render
before `config.full` lands matches the eventual normalized value.
`turnController.recordMessageComplete` and `recordMessageDelta` both
prioritised `payload.rendered` over `payload.text`. `payload.rendered`
is the Rich-Console output `tui_gateway` builds for terminals that
can't render markdown themselves; the TUI already renders markdown via
`<Md>`. Two real bugs follow:
1. **Final answer garbled when `display.final_response_markdown: render`
is set** (#16391). Raw ANSI escape sequences pass through into the
React tree and the user sees overlapping coloured text instead of
their answer.
2. **Streaming silently drops content.** Per-delta `rendered` is an
*incremental* Rich fragment. The previous code did
`this.bufRef = rendered ?? this.bufRef + text`, which on every tick
replaced the whole accumulated buffer with the latest mid-sequence
ANSI fragment. Long replies arrived truncated and looked
half-painted — easy to miss as "model is being terse" instead of a
client bug.
Fix:
* `recordMessageComplete` now prefers `payload.text`, falling back to
`payload.rendered` only when the gateway elected not to send any.
* `recordMessageDelta` always accumulates `text`; `rendered` is ignored
on the streaming path entirely (Ink does its own markdown render via
`<Md>` / `streamingMarkdown.tsx`).
Tests:
* `prefers raw text over Rich-rendered ANSI on message.complete` —
the assistant message reflects raw markdown, not ANSI.
* `falls back to payload.rendered when text is missing` — preserves
the legacy "no `text`, only ANSI" path used by some adapters.
* `always accumulates raw text in message.delta and ignores rendered` —
pre-fix code would have made this assertion fail because each delta
overwrote the buffer.
Validation: `npm run type-check` clean, `npm test --run` 392/392 pass.
* fix(tui): make /browser connect actually take effect on the live agent
Reports were that `/browser connect <url>` (and "changes to CDP url
don't get picked up") didn't propagate to the live agent in `--tui`,
forcing users to fall back to setting `browser.cdp_url` in
`config.yaml` and restarting. Tracing the path on current main shows
the protocol wiring is already correct — `/browser` is registered in
`ui-tui/src/app/slash/commands/ops.ts` and dispatches `browser.manage`
through the gateway RPC, NOT the slash worker (covered by the
`browser.manage` row in `slashParity.test.ts`). But three real gaps
left the experience flaky:
1. `cleanup_all_browsers()` ran AFTER `os.environ["BROWSER_CDP_URL"]`
was rewritten. `_ensure_cdp_supervisor(...)` reads the env to
resolve its target URL, so a tool call landing in that brief window
could re-attach the supervisor to the OLD CDP endpoint just before
we reaped sessions, leaving the agent talking to a dead URL.
Reorder to clean first, swap env, clean again so the supervisor
for the default task is definitively closed.
2. `browser.manage status` reported only the env var, ignoring
`browser.cdp_url` from config.yaml. `_get_cdp_override()` (the
resolver the agent itself uses) consults both — match it so
`/browser status` answers the same question the next
`browser_navigate` will see. Closes a stealth bug where users
saw "browser not connected" while their CDP URL was perfectly
set in config.yaml.
3. `/browser disconnect` only cleared `BROWSER_CDP_URL` and reaped
once, leaving the same swap window as connect. Symmetrical
double-cleanup here too.
Frontend (`ops.ts`):
* Echo "next browser tool call will use this CDP endpoint" on success
so users see immediate confirmation that the gateway accepted the
swap, even before any tool runs.
* Mention `browser.cdp_url` in `config.yaml` in the usage hint and
the not-connected status line. Persistent config is the correct
fix for some terminal-multiplexer / sub-agent flows where env
inheritance is unreliable; surfacing it makes that workaround
discoverable.
Tests (4 new, all hermetic):
* `status` returns the resolved URL when only `browser.cdp_url` is
set in config.yaml.
* `connect` writes env AND cleans before/after, in that order.
* `connect` against an unreachable endpoint does NOT mutate env or
reap.
* `disconnect` removes env and cleans twice.
Validation:
scripts/run_tests.sh tests/test_tui_gateway_server.py — 94/94 pass.
cd ui-tui && npm run type-check — clean; npm test --run — 389/389.
* review(copilot): always defer to _get_cdp_override; normalize bare host:port
* review(copilot): collapse discovery-style CDP paths so /json/version isn't duplicated
* fix(tui): /browser status must not perform CDP discovery I/O
Copilot review on PR #17120: previous version routed through
`tools.browser_tool._get_cdp_override`, which calls
`_resolve_cdp_override` and performs an HTTP probe to /json/version
with a multi-second timeout for discovery-style URLs. That blocks
the TUI on `/browser status` whenever the configured host is slow
or unreachable.
Status now reads env-then-config directly with no network I/O. The
WS normalization still happens in `browser_navigate` for actual
tool calls, so behaviour-on-call is unchanged.
* fix(tui): skip /json/version probe for concrete ws://devtools/browser endpoints
Round 2 Copilot review on PR #17120: hosted CDP providers (Browserbase,
browserless, etc.) return concrete `ws[s]://.../devtools/browser/<id>`
URLs which are already directly connectable but don't serve the HTTP
discovery path. The previous `/json/version` probe rejected these
valid endpoints with 'could not reach browser CDP'.
For `ws[s]://...` URLs whose path starts with `/devtools/browser/` we
now do a TCP-level reachability check (`socket.create_connection`)
instead of the HTTP probe. The actual CDP handshake happens on the
next `browser_navigate` call, so we still surface unreachable hosts
as 5031 errors — just without the false negatives.
Discovery-style URLs (`http://host:port[/json[/version]]`) keep the
HTTP probe path unchanged. Updated existing test + added two new
ones (TCP-only success, TCP unreachable → 5031).
* feat(tui): opt-in auto-resume of the most recent session
`hermes --tui` always forges a fresh session at startup unless the user
sets `HERMES_TUI_RESUME=<id>`. Disconnects, terminal-window crashes,
and accidental Ctrl+D therefore lose every piece of in-flight context
even though `state.db` still has the full history a `/resume` away.
Add an opt-in path that mirrors classic CLI's `hermes -c` muscle
memory: when `display.tui_auto_resume_recent: true` is set in
`~/.hermes/config.yaml`, the TUI looks up the most recent human-facing
session and resumes it instead of starting fresh. Default off so
existing users aren't surprised; explicit `HERMES_TUI_RESUME` always
wins.
Wires:
* New `session.most_recent` JSON-RPC in `tui_gateway/server.py` that
returns the first non-`tool` row from `list_sessions_rich`, or
`{"session_id": null}` when none. Uses the same deny-list as
`session.list` so sub-agent rows can't sneak in.
* `createGatewayEventHandler.handleReady` re-ordered: explicit
`STARTUP_RESUME_ID` first (unchanged), then conditional auto-resume
via `config.get full → display.tui_auto_resume_recent`, then the
legacy `newSession()` fallback. Failures of either RPC fall back
to `newSession()` so the path is always finite.
* Default `display.tui_auto_resume_recent: False` added to
`DEFAULT_CONFIG` in `hermes_cli/config.py` (no `_config_version`
bump per AGENTS.md — deep-merge handles the additive key).
Tests:
* 4 new vitest cases in `createGatewayEventHandler.test.ts` cover
every gate-and-fallback combination (env wins, config off, config
on with hit, config on with miss).
* 3 new pytest cases for `session.most_recent` (denied row skip,
tool-only → null, db-unavailable → null).
Validation:
scripts/run_tests.sh tests/test_tui_gateway_server.py — 93/93.
cd ui-tui && npm run type-check — clean; npm test --run — 393/393.
* review(copilot): fold session.most_recent errors into null + extend ConfigDisplayConfig
* review(copilot): cover RPC-rejection fallbacks in auto-resume tests
* fix(tui): drop stale stream events after ctrl-c interrupt
Once interruptTurn() flips this.interrupted, only recordMessageDelta
short-circuited. recordReasoningDelta/Available, recordToolStart/
Progress/Complete, and recordInlineDiffToolComplete kept populating
turnState until the python loop reached its next _interrupt_requested
check (~1s on busy turns), making it look like ctrl-c was ignored
while late "thinking" + tool calls kept landing in the UI.
Add the same interrupted guard to every stream-side recorder, and
clear the flag at startMessage() so the next turn isn't suppressed
if the previous turn never delivered message.complete.
* fix(tui): guard recordTodos against post-interrupt mutation; fake-timers in test
Copilot review on PR #16706:
1. `recordToolStart` is interruption-guarded, but `tool.start`
handler also calls `recordTodos(payload.todos)` first — so a
late tool.start carrying todos could still mutate `turnState.todos`
after Ctrl-C, leaving ghost rows in the panel. Adds the same
`if (this.interrupted) return` early-exit to `recordTodos` so
*all* tool.start side-effects are dropped post-interrupt.
2. The interrupt test was leaking a real `setTimeout` (interrupt
cooldown) across test files, which could fire later and mutate
uiStore from the wrong test context. Wraps the test in
`vi.useFakeTimers()` + `vi.runAllTimers()` and restores real
timers in finally.
3. Extends the same test with a todos payload on the post-interrupt
tool.start so we have explicit regression coverage for #1.
* fix(tui): guard pushTrail post-interrupt; harden interrupt-test cleanup
Round 2 Copilot review on PR #16706:
1. `tool.generating` events route through `pushTrail`, which was not
interruption-guarded — late events could still write 'drafting …'
into `turnTrail` after Ctrl-C, leaving a stale shimmer in the UI.
Adds the same `if (this.interrupted) return` early-exit.
2. Test cleanup moved `vi.runAllTimers()` into `finally` (before
`vi.useRealTimers()`) so a mid-test assertion failure can't leak
the interrupt-cooldown setTimeout across other test files.
3. Replaced the misleading 'pre-interrupt todos … expected to be
cleared by the interrupt cycle' comment with an accurate one
reflecting current behaviour (interrupt does NOT clear todos).
4. Added an explicit assertion that a post-interrupt `tool.generating`
event does not extend `turnTrail` — regression coverage for #1.
* fix(tui): append gateway stderr tail to start_timeout activity
`gateway.start_timeout` previously published only `cwd` + `python`,
which made TUI startup failures hard to disambiguate. The user saw
`gateway startup timed out · /path/to/python /repo · /logs to inspect`
with no signal whether the actual cause was a wrong python interpreter,
a missing dependency, or a config parse failure.
Plumb a 20-line stderr tail through the event so the most useful lines
land directly in the TUI activity feed, capped to the last 8 non-empty
lines for readability:
* `gatewayClient.ts` — collect `getLogTail(20)` when the readyTimer
fires and attach it as `payload.stderr_tail`.
* `gatewayTypes.ts` — extend the `gateway.start_timeout` event union
with the new optional field.
* `createGatewayEventHandler.ts` — emit the trimmed lines after the
existing `gateway startup timed out` activity entry, classified
`error`.
Tests: regression test in `createGatewayEventHandler.test.ts` checks
that `ModuleNotFoundError` / `FileNotFoundError` lines from the tail
land in `getTurnState().activity` so they show up in the UI immediately.
Validation: `npm run type-check` clean, `npm test --run` 390/390.
* review(copilot): filter blanks before slice and cap stderr tail at 120 chars
Tables rendered through `<Md>` had no separator and no header weight,
so they read as a paragraph with extra whitespace. This adds two tiny,
border-free changes that survive Ink's grapheme-approximate column
widths better than a full outline:
* Bold the header row, keeping the existing amber colour.
* Insert a dim `─`-dashed rule between the header and body rows.
We deliberately stay away from a full outline — column widths are
measured via `stripInlineMarkup(...).length`, which is grapheme-aware
but still off by a cell on East Asian wide characters and emoji-mid-
cell strings. A header rule plus the existing 2-space column gap
gives the visual hierarchy the issue asks for without amplifying that
inaccuracy into a misaligned border.
Validation: `npm run type-check` clean, `npm test --run` 389/389.
- moveCursor(extend=true) now collapses to the bare cursor when the
computed offset equals the existing anchor instead of leaving a
zero-length sel. Without this, Shift+Left at col 0 / Shift+Home at
start would silently hide the hardware cursor (selected truthy)
without rendering any highlight.
- _tui_need_npm_install also catches UnicodeDecodeError so a corrupted
/ non-UTF8 lockfile falls back to the mtime path the docstring
promises instead of crashing.
Made-with: Cursor
* feat(tui): auto copy-on-select for transcript text
Drag in the transcript already highlighted but you had to press Cmd+C to
land it on the clipboard, and the highlight cleared on copy — most users
never realised selection existed. Now drag-release fires copySelectionNoClear
so the text is on the clipboard immediately while the highlight stays put,
matching iTerm2's "Copy to pasteboard on selection" default. Esc clears.
Behaviour:
- Single click in the input still positions the cursor (TextInput onClick).
- Single click in the transcript still does nothing destructive.
- Double / triple click select word / line, then drag extends.
- /copyselect [on|off|toggle] (alias /cos) flips the setting at runtime,
HERMES_TUI_DISABLE_COPY_ON_SELECT=1 disables at startup, persists via
display.tui_copy_on_select in config.yaml.
Help overlay now lists drag-select, multi-click, and click-to-position
so the gestures are discoverable.
Made-with: Cursor

Add mouse drag selection and Shift+Arrow/Home/End extension inside the TUI composer so prompt text behaves like a normal editable field while keeping click-to-position and right-click paste intact.

* fix(tui): allow composer selection from prompt whitespace
Give the composer a one-cell mouse capture pad before the editable text. The prompt glyph/gutter still does not become selectable, but dragging from the edge now anchors at input offset 0 so users do not need to hit the first character precisely.
Made-with: Cursor
* fix(tui): clear selections from blank composer space
Clicking blank space in the transcript or composer now clears active TUI/input selections like a normal text surface. TextInput clicks stop bubbling so cursor placement and selection gestures keep their local behavior.
Made-with: Cursor
* fix(tui): delegate prompt gutter drags to composer text
The prompt gutter is now an input gesture region, not selectable content. Dragging from the whitespace or prompt area anchors the composer selection at offset 0, while selection highlight/copy remains limited to actual input text.
Made-with: Cursor
* fix(tui): move composer cursor to end on selection clear
External clear actions now collapse the composer selection to the end of the input, matching normal text-field behavior after dismissing a selection.
Made-with: Cursor
* fix(tui): capture composer padding before prompt
Add an explicit mouse capture cell over the left padding before the prompt glyph. Drags starting there now delegate to the composer input at offset 0 instead of starting terminal-level selection over the prompt chrome.
Made-with: Cursor
* fix(tui): avoid npm install on lockfile mtime churn
Compare package-lock.json against npm's hidden node_modules lock by content instead of mtimes. Git checkouts and npm lock rewrites can make the root lockfile newer even when installed dependencies already match, causing hermes --tui to print Installing TUI dependencies on every launch.
Made-with: Cursor
* fix(tui): include prompt leading cell in gesture region
Use the prompt box's real layout region to cover the leading whitespace cell before the glyph. The cell now participates in mouse hit testing and delegates to composer selection instead of starting terminal-level selection.
Made-with: Cursor
* fix(tui): widen prompt-side gesture capture band
Capture a wider left-side band around the composer prompt row so drags starting in terminal gutter/padding cells are consumed and delegated to input selection, instead of triggering terminal-level selection chrome.
Made-with: Cursor
* fix(tui): make pre-prompt spacer non-selectable content
Replace the sticky-prompt fallback `Text(' ')` with an empty spacer box so the visual gap remains but no literal space character is rendered/copyable before the composer prompt.
Made-with: Cursor
* fix(tui): capture pre-prompt spacer without shifting prompt layout
Revert the widened negative-margin prompt capture band and instead capture drags on the dedicated spacer row above the prompt. This keeps prompt/text alignment stable while still delegating whitespace-start drags to composer selection.
Made-with: Cursor
* fix(tui): align prompt with status bar and capture full input row
Drop the leading prompt column from 3 to 2 so the input first character lines up with the status bar text. Wrap the prompt+input row in a single mouse-capture box and stop event propagation from TextInput's own handlers so any drag in that row delegates to composer selection without leaking to terminal-level selection.
Made-with: Cursor
* fix(tui): anchor hardware cursor during composer selection
When a composer selection covers a row exactly the column width, the rendered text fills the row and the terminal auto-wraps the hardware cursor to col 0 of the next row, leaving a ghost block beneath the prompt. Park the cursor at the start of the input box during selection so it can't escape the input region.
Made-with: Cursor
* fix(tui): hide hardware cursor during composer selection
Stop fighting auto-wrap by hiding the hardware cursor outright while the
composer has an active selection. This prevents both the ghost block under
the prompt (cursor wrapping past the last cell) and the parked-cursor block
on the first selected character. The cursor restores as soon as the
selection clears or focus changes.

* chore(tui): /clean — drop dead capture-pad path, dedupe gutter handlers
- TextInput: remove unused leftCaptureColumns prop and capture-pad math, drop
unused mouseApi.startAt, fold mouse offset into a single offsetAt helper,
share a MouseEventLite type across the four handlers.
- appLayout: hoist a GutterMouseEvent type and an endInputDrag callback so the
spacer/prompt/input rows share one shape.
- _tui_need_npm_install: lift the runtime-only key set to a module constant,
collapse nested isinstance checks, and document the mtime fallback.
Made-with: Cursor
* fix(tui): address copilot review on PR #16732
- Split InputSelection.clear() into clear() (cursor-preserving) and
collapseToEnd() (clear + jump to end). Cmd+C copy paths keep using
clear() so the cursor stays put; the blank-area click in useMainApp
switches to collapseToEnd() to match the requested UX.
- Spacer-row drags now force row=0 when forwarding into the input,
since the spacer's vertical origin doesn't align with the input box
and Ink mouse-capture keeps dispatching motion to the original
target. Prompt+input row drag keeps localRow because origins match.
Made-with: Cursor
* fix(tui): give TextInput Box an explicit width
After the /clean pass dropped the unused capture-pad math, the wrapping
Box also lost its explicit width and started sizing to its rendered
content. Clicks past the last character missed TextInput and fell
through to the parent prompt-row Box, which collapsed the cursor to
offset 0. Pin the Box back to `columns` so the input owns its full
column span regardless of value length.
Made-with: Cursor
* feat(tui): double-click select-all + hide cursor on terminal blur
- Track click time/offset in TextInput so a quick second click on the
same offset triggers select-all. Ink's screen-level multi-click is
bypassed once our onMouseDown captures, so the gesture has to be
detected locally.
- Extend the cursor-hide effect to also fire when the terminal loses
focus, so the hollow-rect ghost most terminals draw at the parked
cursor position disappears too.
Made-with: Cursor
* chore(tui): /clean — extract isMultiClickAt helper
Pull the click-recurrence math out of TextInput's onMouseDown into a
small isMultiClickAt(offset) helper so the handler reads as the gesture
list it actually is (multi-click → select-all, otherwise start).
Drop the redundant length>0 guard now that selectAll() already noops on
an empty value.

* docs(tui): explain _tui_need_npm_install content-vs-mtime comparison
Expand the docstring so future readers understand why we parse the
lockfiles instead of comparing mtimes, what the optional/peer skip
covers, how stale hidden-lock entries are handled, and when we fall
back to mtime.
- Rename `removeAt` → `removeAtInPlace` and document the mutation
contract; the old name read like a non-mutating helper.
- Hotkey table + queue header: use `Ctrl+X` / `Esc` to match the
rest of the UI (was `⌃X` / `esc`).
- Render the queued header as a single template literal so JSX
text-node whitespace can't sneak into the rendered line.
- Make `Esc` while editing beat the `terminal.hasSelection` clear:
the header promises 'Esc cancel', so an active selection
shouldn't silently consume the keystroke.
The text input's ctrl-passthrough whitelist only listed Ctrl+C and
Ctrl+B. Ctrl+X fell through to the printable-char branch and got
inserted as 'x' alongside the queue-delete action firing in
useInputHandlers.
Add Ctrl+X to the same whitelist so it bypasses the readline-style
fallback and reaches the app-level handler unchanged. When not in
queue-edit mode it's a no-op, which is fine — typing 'x' on Ctrl+X
was the wrong default anyway.
Today there's no way to remove a queued message — ↑ loads it for edit,
ctrl-K dispatches the head, but a draft you no longer want stays put
forever. ctrl-C just clears the composer and exits edit mode without
touching the queue.
Two new bindings, both gated on queueEditIdx !== null so they're
inert when the user isn't pointing at a queue item:
- ctrl-X — delete the queue item being edited, clear composer, exit
edit mode. "cut" matches the mental model and doesn't collide with
any existing binding.
- esc — cancel the edit (composer clears, item stays in queue).
Mirrors ctrl-C's existing behavior so muscle memory has two paths.
Header line now reads `queued (3) · editing 2 · ⌃X delete · esc cancel`
when in edit mode, so the affordance is discoverable without /help.
The /help hotkey table also gets a Ctrl+X entry.
ctrl-C is intentionally unchanged: it should never destroy queued
content. Cancel is non-destructive (esc / ctrl-C); only ctrl-X
removes the item.
Keep the parity test backed by the real Python command registry while avoiding hard failures in Node-only Vitest environments that cannot import hermes_cli.commands.
Expose a small forceRedraw API from @hermes/ink and use it for Ctrl/Cmd+L so the hotkey performs a real terminal clear + full repaint instead of a no-op state patch.
Use explicit repaint patch semantics for Ctrl/Cmd+L and narrow the hotkey assertion to the actual +L entry so unrelated descriptions do not cause false failures.
Harden busy mode config reads against invalid display config shapes and align /fast help+usage text with accepted aliases, with regression coverage for non-dict display values.
Make Ctrl+L non-destructive by redrawing the current screen state instead of starting a new session, and stop auto-appending --global for typed /model commands so session scope remains the default unless explicitly requested.
Route /browser, /reload-mcp, /rollback, /stop, /fast, and /busy through direct TUI RPC handlers so state changes hit the live gateway session instead of slash-worker fallback. Add TUI session finalize/reset parity hooks (memory commit + plugin boundaries) and parity matrix tests to keep mutating commands off fallback.
Route TUI /title through session.title RPC and queue titles when the session DB row is still initializing, so renamed sessions reliably appear in /resume and browse flows.
- drop unused TUI helpers, test-only layout scaffolding, and stale public debug exports
- remove an unused profiler import and trim test-only coverage for deleted helpers
- gateway handler: turnController always archives in recordMessageComplete,
so the post-complete archiveTodosAtTurnEnd().forEach is dead code. Drop
it and the now-unused import.
- turnController: collapse archive prepend into a single spread expression.
- gateway server: one-line comment for the tool.start todo skip.
Two bugs surfaced together while the model fired the todo tool:
1. Count flickered (e.g. 3 → 1 → 3) because tool.start echoed
args.todos as the live state. With merge=true (or any partial
replacement) args.todos is just the items being updated, not the
full list. Drop the early echo — tool.complete already carries the
canonical full list from the tool result.
2. After turn end the panel jumped from under the user prompt to below
thinking/tools because archiveDoneTodos() was pushed AFTER segments
in finalMessages. Prepend the archive trail msg so it sits right
after the user prompt — same visual slot the live panel occupied
during streaming.
Four independent session-UX bugs reported by an external user (#16294).
/save wrote hermes_conversation_<ts>.json to CWD — invisible to
'hermes sessions browse' and easy to lose. Snapshots now write under
~/.hermes/sessions/saved/ and the command prints the absolute path plus
a 'hermes --resume <id>' hint for the live DB-indexed session.
'hermes sessions browse' default --limit raised from 50 to 500. With the
old ceiling, users with moderately long histories saw only the most
recent 50 rows and assumed older sessions had been lost.
TUI session.list (`/resume` picker) switched from a hardcoded allow-list
of 13 gateway source names to a deny-list of just { 'tool' }. Sessions
tagged acp / webhook / user-defined HERMES_SESSION_SOURCE values and
any newly-added platform now surface. Default limit 20 → 200.
ollama-cloud provider setup passes force_refresh=True to
fetch_ollama_cloud_models() so a user entering their API key sees the
fresh catalog (e.g. deepseek v4 flash, kimi k2.6) immediately instead
of waiting up to an hour for the disk cache TTL to expire.
Closes#16294.
