The Ink TUI (\`hermes --tui\` + dashboard \`/chat\`) had no wiring for the
background self-improvement review. When the review fired and patched
a skill or saved a memory entry, the change landed but the user had
no visual indication it happened — only the CLI had a print surface
for the '💾 Self-improvement review: …' line.
Changes:
- tui_gateway/server.py: in _init_session, attach
agent.background_review_callback to an _emit('review.summary',
sid, {text}) closure. Wrapped in try/except so agents with locked
attribute slots don't break session startup.
- ui-tui/src/app/createGatewayEventHandler.ts: handle 'review.summary'
by routing ev.payload.text through sys(…), matching the existing
'background.complete' pattern. Empty / whitespace payloads are
ignored so the transcript never gets a blank system line.
- ui-tui/src/gatewayTypes.ts: extend the GatewayEvent discriminated
union with { type: 'review.summary', payload?: { text?: string } }.
Gateway platforms (Telegram, Discord, Slack, …) already route the
review summary via background_review_callback → post-delivery queue
in gateway/run.py, so they pick up the new 'Self-improvement review:'
prefix from the companion run_agent change with no platform edits.
Tests:
- tests/tui_gateway/test_review_summary_callback.py (Python, 2 tests):
_init_session attaches a callback that emits the right event; the
callback path survives agents that can't accept the attribute.
- ui-tui/src/__tests__/createGatewayEventHandler.test.ts (vitest, 2
new cases): review.summary events feed sys(...) with the full text;
empty / missing payloads are no-ops.
- TypeScript type-check passes.
- tui_gateway suite: 64/64 pass.
Three narrow fixes targeting the remaining red checks after #17828:
1. ui-tui/src/app/slash/commands/ops.ts (Docker Build):
/reload-mcp's local params type annotated session_id: string
while ctx.sid is string | null. Widen to string | null —
matches every other rpc call site and the test harness which passes
{ session_id: null }. Fixes TS2322 on line 86. The rpc signature
itself is Record<string, unknown>, so this is purely a local
typing fix, no behavioral change.
2. tests/plugins/test_achievements_plugin.py (13 cascading test failures):
_install_fake_session_db did a raw sys.modules['hermes_state'] =
fake_module without restoration, leaking the fake across xdist
worker boundaries. Downstream tests doing from hermes_state import
SessionDB got a module whose SessionDB was lambda: fake_db
— 6 test_hermes_state.py tests failed with AttributeError: 'function'
object has no attribute '_sanitize_fts5_query' / _contains_cjk,
and 7 test_860_dedup.py tests failed with TypeError: got unexpected
keyword argument 'db_path' (real code calls SessionDB(db_path=...)).
Fix: stash monkeypatch on the plugin_api module object in the
fixture, and have the helper do monkeypatch.setitem(sys.modules,
'hermes_state', fake_module) for auto-restoration at test teardown.
3. tests/hermes_cli/test_web_server.py (WS race):
TestPtyWebSocket::test_pub_broadcasts_to_events_subscribers hit the
30s test timeout on CI. websocket_connect returns after
ws.accept() — but /api/events registers the subscriber in
_event_channels on the NEXT await (inside _event_lock). A
publish immediately after connect could race ahead of registration
and be dropped, and the subsequent receive_text() blocked until
SIGALRM killed the test. Fix: poll _event_channels after the
subscriber connects, before publishing.
Validation:

Remaining red checks are pure infra (Nix ubuntu hits
TwirpErrorResponse ResourceExhausted on the GH Actions cache API; Nix
macos bounces between npm build openssl-legacy and cache rate-limits)
and cannot be fixed in the codebase.
feat(gateway): refine Platform._missing_ and platform-connected dispatch
Restricts plugin-name acceptance to bundled plugin scan + registry
(no arbitrary string -> enum-pollution), pulls per-platform connectivity
checks into a _PLATFORM_CONNECTED_CHECKERS lambda map with a clean
_is_platform_connected method, and adds tests covering the checker map,
plugin platform interface, and IRC setup wizard.
Reloading MCP servers rebuilds the tool set for the active session, which
invalidates the provider prompt cache (tool schemas are baked into the
system prompt). The next message re-sends full input tokens — can be
expensive on long-context or high-reasoning models.
To surface that cost, /reload-mcp now routes through a new slash-confirm
primitive with three options: Approve Once / Always Approve / Cancel.
'Always Approve' persists approvals.mcp_reload_confirm: false so future
reloads run silently.
Coverage:
* Classic CLI (cli.py) — interactive numbered prompt.
* TUI (tui_gateway + Ink ops.ts) — text warning on first call; `now` /
`always` args skip the gate; `always` also persists the opt-out.
* Messenger gateway — button UI on Telegram (inline keyboard), Discord
(discord.ui.View), Slack (Block Kit actions); text fallback on every
other platform via /approve /always /cancel replies intercepted in
gateway/run.py _handle_message.
* Config key: approvals.mcp_reload_confirm (default true).
* Auto-reload paths (CLI file watcher, TUI config-sync mtime poll) pass
confirm=true so they do NOT prompt.
Implementation:
* tools/slash_confirm.py — module-level pending-state store used by all
adapters and by the CLI prompt. Thread-safe register/resolve/clear.
* gateway/platforms/base.py — send_slash_confirm hook (default 'Not
supported' → text fallback).
* gateway/run.py — _request_slash_confirm helper + text intercept in
_handle_message (yields to in-progress tool-exec approvals so
dangerous-command /approve still unblocks the tool thread first).
Tests:
* tests/tools/test_slash_confirm.py — primitive lifecycle + async
resolution + double-click atomicity (16 tests).
* tests/hermes_cli/test_mcp_reload_confirm_gate.py — default-config
shape + deep-merge preserves user opt-out (5 tests).
Targeted runs (hermetic): 89 passed (slash-confirm, config gate,
existing agent cache, existing telegram approval buttons).
Single-key confirm matches how the picker already accepts 1-9 to
resume — no separate y/n keymap to learn — and "press d again" is
self-documenting next to the cursor.
Pressing `d` on the highlighted row in the resume picker prompts
`delete? y/n`; `y` deletes the session (DB row + on-disk transcript
files), anything else cancels. The active session is excluded from
deletion server-side.
Adds a new `session.delete` JSON-RPC handler that wraps
`SessionDB.delete_session`, forwarding the per-profile `sessions/`
directory so transcripts get cleaned up alongside the row.
Reset sticky mouse/focus/paste terminal modes before the TUI starts and during graceful shutdown paths so stale tab state from prior crashes cannot poison the next session.
Route Option/Alt or Ctrl wheel input through a gated precision path that scrolls at most one row per short interval, while preserving the existing accelerated behavior for plain wheel input. Keep precision active briefly after modifier release so queued wheel events from the same gesture do not jump into acceleration mid-stream.
* fix(tui): offload manual compaction RPC
Route TUI session compression through the existing long-handler pool so slow compaction does not block other gateway RPCs.
* fix(tui): show compaction progress immediately
Print a local status line before the compress RPC starts so slow manual compaction does not look like a no-op.
* feat(tui): rich /compress feedback parity with CLI
Show pre-compaction message count and rough token estimate immediately, emit a status update so the bottom bar reflects ongoing compaction, and report a multi-line summary (headline + token delta + optional note) using the shared summarize_manual_compression helper.
* fix(tui): show live compaction estimate in transcript
Mirror compression progress status into the transcript so users see the backend message count and token estimate while /compress is still running.
* fix(tui): single live compaction line with spinner glyph
Drop the redundant local "compressing context..." placeholder and prefix the live backend status line with a braille spinner glyph so /compress reads as a single in-progress row.
* fix(tui): address review nits on /compress feedback
Reuse the precomputed token estimate inside _compress_session_history so the gateway does not redo the O(n) work while holding history_lock, keep the status bar pinned during long manual compactions instead of auto-restoring after 4s, and drop the redundant noop bullet that doubled with the system role glyph.
* fix(tui): release history_lock during compaction LLM call
Move the snapshot/commit pattern into _compress_session_history so the lock is held only across the in-memory bookkeeping, not during agent._compress_context. Also emit a final neutral status update from session.compress so the pinned compressing indicator clears even on errors.
* fix(tui): rebuild prompt cleanly + sync session_key after compress
Pass system_message=None so AIAgent._compress_context rebuilds the system prompt without nesting the cached identity block. Reuse the handler's pre-snapshotted history inside _compress_session_history to avoid a second O(n) copy under the lock. After compaction, when AIAgent._compress_context rotates session_id, sync the gateway session_key, migrate approval notify + yolo state, restart the slash worker, and clear the stale pending title. Mirrors HermesCLI._manual_compress.
* Avoid /compress lock re-entry in slash side effects.
Stop pre-locking history before _compress_session_history in slash command mirroring, keep session-key sync parity with manual compression, and add a regression test that asserts /compress is invoked without holding history_lock.
* fix(tui): word-wrap composer input
Wrap composer input at word boundaries and anchor the good-vibes heart to the full composer row.
* test(tui): cover composer word wrap edge
Add regression coverage for moving the next word instead of splitting it at the composer edge.
Copilot caught that clearing inFlight on a transient normal-memory tick could
allow a second dump/eviction to start before the first async tick completed.
Only clear dumped on normal; let the in-flight tick's finally remove its own
level.
Tests:
- cd ui-tui && npm run type-check && npm run build
Classic CLI exposes ``/reload`` (re-reads ~/.hermes/.env into
``os.environ`` via ``hermes_cli.config.reload_env``) so newly added API
keys take effect without restarting the session. The TUI was missing
the parity command, so users had to Ctrl+C out and ``hermes --tui``
again whenever they added or rotated a credential.
Three small wires:
* New ``reload.env`` JSON-RPC method in ``tui_gateway/server.py`` that
delegates to ``hermes_cli.config.reload_env`` and returns the count
of vars updated.
* New ``/reload`` slash command in ``ui-tui/src/app/slash/commands/ops.ts``
matching the existing ``/reload-mcp`` pattern (native RPC, no slash
worker).
* Drop ``cli_only=True`` from the ``reload`` ``CommandDef`` in
``hermes_cli/commands.py`` so help/menus surface it in the TUI too.
``reload_env`` itself is environment-agnostic.
Same caveat as classic CLI: the *currently constructed* agent's
credential pool / provider routing does not auto-rebuild. Users who
want a brand-new credential resolution should follow with ``/new``.
Tests:
* New ``test_reload_env_rpc_calls_hermes_cli_reload_env`` confirms
RPC delegates and reports the count.
* New ``test_reload_env_rpc_surfaces_errors`` confirms exceptions are
rendered as JSON-RPC errors.
* ``createSlashHandler.test.ts`` slash-parity matrix extended with
``['/reload', 'reload.env', {}]`` so we can't regress the routing.
Validation:
scripts/run_tests.sh tests/test_tui_gateway_server.py — 92/92.
scripts/run_tests.sh tests/hermes_cli/test_commands.py — 128/128.
cd ui-tui && npm run type-check — clean; npm test --run — 390/390.
Fixes from Copilot's two passes on PR #17238:
* Validate parsed URL once: reject missing host, invalid port, and
unsupported scheme up front so malformed inputs (e.g. http://:9222
or http://localhost:abc) don't fall through to a generic 5031.
* Tighten _is_default_local_cdp to require a discovery-style path so
ws://127.0.0.1:9222/devtools/browser/<id> is not collapsed to bare
http://127.0.0.1:9222 (which would lose the path and break the
connect).
* Move browser.manage into _LONG_HANDLERS so the up-to-10s
launch-and-retry loop runs on the RPC pool instead of blocking the
main dispatcher.
* try_launch_chrome_debug uses Windows-appropriate detach kwargs
(creationflags=DETACHED_PROCESS|CREATE_NEW_PROCESS_GROUP) instead
of POSIX-only start_new_session=True.
* manual_chrome_debug_command uses subprocess.list2cmdline on
Windows so the printed instruction is cmd.exe-compatible.
* Mirror host/port validation in cli.py /browser connect so the
classic CLI never persists an invalid BROWSER_CDP_URL.
Split browser.manage into a small dispatcher with named connect/disconnect
helpers, fold _http_ok / _probe_urls / _normalize_cdp_url out of the nested
probe loop, collapse the failure-message scaffolding, and DRY the chrome
candidate path tables. Behaviour and event shape unchanged.
Emit browser.progress JSON-RPC notifications during the connect work and render them in the TUI as system transcript lines, so users see the same step-by-step status the base CLI prints instead of nothing for ~1m followed by a final result.
Return CLI-style browser connect status messages from the gateway and render them in the TUI so local Chrome launch attempts are visible instead of ending in a silent delayed failure.
Share Chrome CDP launch helpers between the classic CLI and TUI so default /browser connect uses loopback consistently, retries local Chrome launch, and reports a copyable manual-start command instead of claiming a dead connection.
Clean up the remaining review nits:
- let the deferred @hermes/ink import retry after a transient failure instead
of memoizing a rejected promise forever
- keep memory-monitor in-flight state inside a finally so future exceptions
cannot suppress that memory level indefinitely
- use read_raw_config for the TUI MCP cold-start probe instead of full
load_config()
- keep input.detect_drop for explicit relative path prefixes (./ and ../)
while preserving the no-RPC fast path for ordinary plain prompts
Tests:
- python -m py_compile tui_gateway/server.py tui_gateway/entry.py
- cd ui-tui && npm run type-check && npm run build
- scripts/run_tests.sh tests/tui_gateway/test_protocol.py::test_sess_found tests/tools/test_code_execution_modes.py tests/tools/test_code_execution.py
- cd ui-tui && npm test -- --run src/__tests__/useSessionLifecycle.test.ts src/__tests__/useConfigSync.test.ts
Copilot correctly flagged two concurrency windows:
- memoryMonitor could re-enter while awaiting the lazy @hermes/ink import or
heap dump, producing duplicate imports/dumps under sustained pressure.
- _start_agent_build used a check-then-set guard without synchronization, so
concurrent agent-backed RPCs could start duplicate agent builders.
Fix both with single-flight guards: cache the dynamic import promise and track
per-level dump in-flight state in memoryMonitor, and protect the TUI agent build
flag with a per-session lock.
Tests:
- python -m py_compile tui_gateway/server.py
- cd ui-tui && npm run type-check && npm run build
- cd ui-tui && npm test -- --run src/__tests__/useSessionLifecycle.test.ts src/__tests__/useConfigSync.test.ts
- scripts/run_tests.sh tests/tui_gateway/test_protocol.py::test_sess_found tests/tools/test_code_execution_modes.py tests/tools/test_code_execution.py
The lazy startup panel could remain stuck on the placeholder when no first
prompt was submitted because agent construction only started from _sess(). Keep
session.create cheap, but schedule _start_agent_build shortly after returning
the placeholder so tools/skills hydrate automatically.
Also replace the ugly placeholder bar rows with compact unicode-animations
braille loaders for the tools and skills sections.
Tests:
- python -m py_compile tui_gateway/server.py
- cd ui-tui && npm run type-check && npm run build
- cd ui-tui && npm test -- --run src/__tests__/useSessionLifecycle.test.ts src/__tests__/useConfigSync.test.ts
- scripts/run_tests.sh tests/tui_gateway/test_protocol.py::test_sess_found tests/tools/test_code_execution_modes.py tests/tools/test_code_execution.py
Match classic CLI perceived startup behavior: show the TUI shell and composer
before constructing the full AIAgent. session.create now returns a lightweight
placeholder session with lazy=true and no longer starts _make_agent eagerly.
The first method that needs the agent triggers _start_agent_build() via _sess();
prompt.submit is routed through the RPC worker pool so that the initial wait for
agent construction does not block the stdio dispatcher.
The intro panel renders skeleton rows for tools/skills while the real
session.info payload is absent, then hydrates to the real tools/skills panel once
AIAgent initialization completes. Also skip the startup /voice status probe and
avoid the input.detect_drop RPC for ordinary plain-text prompts to keep early
startup/first-submit paths cheap.
Measurements on macOS Terminal.app:
- Previous full ready p50 after earlier PR commits: ~1537ms
- Lazy skeleton panel p50: ~794ms
- Original baseline full ready p50: ~1843ms
So the visible startup surface is now ~743ms faster than the prior PR state and
~1.05s faster than the original baseline. First prompt still pays the same agent
construction cost if it races the background/skeleton state, matching classic
CLI's deferred behavior.
Tests:
- python -m py_compile tui_gateway/server.py
- cd ui-tui && npm run type-check && npm run build
- scripts/run_tests.sh tests/tui_gateway/test_protocol.py::test_sess_found tests/tools/test_code_execution_modes.py tests/tools/test_code_execution.py
- cd ui-tui && npm test -- --run src/__tests__/useSessionLifecycle.test.ts src/__tests__/useConfigSync.test.ts
Keep the latest prompt sticky while the viewport is in live assistant output beyond history, and clear stale sticky state at the real bottom using fresh scroll height.
Address two Copilot review comments on PR #17175.
- `wrapForFrac` doc said "additive operators or whitespace" but the
implementation also matches `*` and `/`. The wider behaviour is the
one we want (nested products and fractions need parens to disambiguate
inline `/`), so the doc is updated to match instead of tightening the
regex.
- `fenceOpenAt` was flagged as "overly conservative" vs. `markdown.tsx`,
which falls back to paragraph rendering for unclosed `$$` openers.
Mirroring that fallback in the streaming chunker would prematurely
commit a paragraph rendering of the unclosed opener to the monotonic
stable prefix, where it would be frozen and become wrong the moment
the closer streams in. The asymmetry is deliberate; document why so
it isn't "fixed" again later.
Made-with: Cursor
Two targeted fixes on the critical path from `hermes --tui` launch to
`gateway.ready`:
1. **Defer `@hermes/ink` import in memoryMonitor.ts.** The static top-level
import dragged the full ~414KB Ink bundle (React + renderer + all
components/hooks) onto the critical path *before* `gw.start()` could
spawn the Python gateway — serialising ~155ms of Node work in front of
it on every launch. `evictInkCaches` only runs inside the 10-second
tick under heap pressure, so it moves to a lazy dynamic import. First
tick hits the ESM cache because the app entry has long since imported
`@hermes/ink`.
2. **Gate `tools.mcp_tool` import on config in tui_gateway/entry.py.**
Importing the module transitively pulls the MCP SDK + pydantic + httpx
+ jsonschema + starlette formparsers (~200ms). The overwhelming
majority of users have no `mcp_servers` configured, so this runs for
nothing. A cheap `load_config()` check (~25ms) skips the 200ms import
when no servers are declared, with a conservative fallback to the old
behaviour if the config probe itself fails.
## Measurements (macOS Terminal.app, Apple Silicon, n=12)
| Metric | Before (p50) | After (p50) | Δ |
|----------------------------|--------------|-------------|----------|
| Python gateway boot alone | 252–365ms | 105–151ms | −180ms |
| `hermes --tui` banner paint | 686ms | 665ms | −21ms |
| `hermes --tui` → ready | **1843ms** | **1655ms** | **−188ms (−10.2%)** |
| `hermes --tui` → ready p90 | 1932ms | 1778ms | −154ms |
| stdev (ready) | 126ms | 83ms | also more consistent |
## Tests
- `scripts/run_tests.sh tests/tui_gateway/ tests/tools/test_mcp_tool.py`:
195 passed. (The one pre-existing failure in
`test_session_resume_returns_hydrated_messages` reproduces on main —
unrelated, it's a mock-DB kwarg mismatch.)
- `ui-tui` vitest: 430 tests, all pass.
- `npm run type-check` in ui-tui: clean.
## Notes
- Node-side first paint ("banner") didn't move meaningfully because that
latency is dominated by Ink's render pipeline + React mount, not by
which imports load first.
- The win shows up entirely in the time from banner to `gateway.ready`
— exactly where we expected it, since both fixes shorten the Python
gateway's boot path or let it overlap more with Node startup.
- No user-visible behaviour change. Memory monitoring still fires every
10s; MCP still works when `mcp_servers` is configured.
* 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.
