Single biggest user-facing change: you can now switch local↔cloud LLM by voice
without restarting. Plus four new packs and a perf nudge.
Shared LLM global (crates/jarvis-core/src/llm/mod.rs)
- GLOBAL: Lazy<RwLock<Option<Arc<LlmClient>>>>. Single source of truth.
- init_global() / current() / swap_to(LlmBackend) / current_backend_name() / parse_backend(str).
- llm_fallback + llm_router migrated: they no longer own a separate LlmClient,
they read from the global on each request. Hot-swap is now LIVE — change
backend, next chat call uses the new one.
- parse_backend accepts both english and russian aliases:
"groq"/"cloud"/"облако"/"клауд" → Groq
"ollama"/"local"/"локал"/"локальный" → Ollama
Voice + Lua LLM switcher (resources/commands/llm_switch/, 3 commands)
- "переключись на локальный" / "перейди на оллама" → swap to Ollama
- "переключись на облако" / "используй грок" → swap to Groq
- "какой у тебя мозг" / "облако или локально" → status query
Underlying Lua API (registered globally):
jarvis.llm({messages}, opts) -- as before, now uses global client
jarvis.llm_status() -> "groq" | "ollama" | "none"
jarvis.llm_switch(name) -> name on success, nil on failure
Media keys pack (resources/commands/media_keys/, 4 commands)
- "пауза" / "плей" → VK_MEDIA_PLAY_PAUSE
- "следующий трек" → VK_MEDIA_NEXT_TRACK
- "предыдущий трек" → VK_MEDIA_PREV_TRACK
- "стоп музыка" → VK_MEDIA_STOP
- Helper _media.ps1 uses user32.keybd_event (P/Invoke through Add-Type).
- Works with anything that listens to global media keys: Spotify, Yandex Music,
YouTube (focused tab), Foobar2000, Winamp, etc. No OAuth, no API keys.
Codebase Q&A pack (resources/commands/codebase_qa/, 3 commands)
- "укажи проект <path>" → stores path in jarvis.memory under codebase.root
- "какой проект сейчас" → speaks current path
- "что делает функция X" / "найди в коде Y" / "объясни код"
→ walks the folder (depth 3, 30 files cap, 4KB per file, 50KB total),
filters by source extensions (rs/py/ts/lua/go/...), feeds digest to LLM
with a "senior reviewer" system prompt, speaks 3-5 sentence answer.
Scheduler cancel-by-text (crates/jarvis-core/src/scheduler.rs)
- new pub fn find_by_text(query, limit) -> Vec<ScheduledTask>
- new pub fn remove_by_text(query) -> usize (count removed)
- new pure helper find_by_text_in(tasks, query, limit) for tests
- Lua: jarvis.scheduler.{find_by_text, remove_by_text}
- Voice: "отмени напоминание про воду" / "удали задачу про разминку"
- 3 new unit tests (52 total in jarvis-core).
TTS pre-warm (crates/jarvis-app/src/main.rs)
- Call jarvis_core::tts::backend() once on startup so the first speak()
doesn't pay Piper binary discovery + voice loading cost. Cuts first-speak
latency by ~150-300ms depending on backend.
Build: cargo build --release -p jarvis-app -p jarvis-gui both green.
Tests: 52/52 jarvis-core unit tests pass.
User asked the code stays easy to fix/extend as the feature surface grows.
This commit refactors what was duplicated, centralises what was scattered,
adds tests where there were none, and writes the architecture doc that
contributors will need.
Deduplication
- tts::play_wav extracted to tts/mod.rs as pub(crate). Was identical in
piper.rs and silero.rs (~25 lines × 2). Both backends now call super::play_wav.
Centralised env config
- new crates/jarvis-core/src/runtime_config.rs — single doc-file for every
JARVIS_* / GROQ_* / OLLAMA_* env var. Includes:
- ENV_* constants with doc comments
- get(name) / get_bool(name, default) / get_parse(name, default) helpers
- feature-flag wrappers: llm_tts_enabled(), llm_router_enabled(),
llm_router_threshold()
- log_effective_config() prints active values on startup
- migrated llm_fallback (JARVIS_LLM_TTS), llm_router (JARVIS_LLM_ROUTER,
JARVIS_LLM_ROUTER_THRESHOLD) to use the new helpers. Pattern set for
future migrations.
Lua boilerplate killer
- new crates/jarvis-core/src/lua/api/cmd.rs exposing:
jarvis.cmd.ok(msg?) — play_ok + speak + {chain=false}
jarvis.cmd.chain_ok(msg?) — same but chain=true
jarvis.cmd.error(msg?) — play_error + speak + {chain=false}
jarvis.cmd.not_found(msg?) — play_not_found + speak + {chain=false}
jarvis.cmd.silent_ok / silent_error
- refactored 5 packs (daily_briefing/off, memory_pack/list, pomodoro/stop,
habit_nudge/stop_all, scheduler/clear) — each lost 3-4 lines of repetitive
play_*/speak/return boilerplate. Pattern for future packs documented in
ARCHITECTURE.md.
Tests (was 32, now 49)
- long_term_memory: 8 new tests for normalize_key, search_in (rank, limit,
empty), build_context_from (empty + populated), serde round-trips for
MemoryRecord and Store. Extracted pure logic (search_in, build_context_from)
into pub(crate) functions to enable testing without global state.
- profiles: 6 new tests for Profile::allows_command (empty/whitelist/blacklist/
deny-wins-over-allow), serde round-trip with all fields + minimal-fields
tolerance via #[serde(default)].
- runtime_config: 2 tests for get_bool / get_parse defaults.
- All 49 tests pass.
New mood/energy log pack
- resources/commands/mood_log/ with 2 commands:
mood.record "запиши настроение 7" / "сегодня мне грустно" → stores
timestamped entry via jarvis.memory.remember
mood.recap "как прошла неделя" → LLM summarises last 30 entries
- Showcase: composes memory + llm + cmd helpers in <30 lines per script.
ARCHITECTURE.md (new, 250 lines)
- Crate layout, data flow diagram (mic→action 10 steps), per-module
responsibility table, configuration layers, TTS pipeline diagram,
Lua sandbox details with API quick-ref, background-services overview,
"how to add a pack/feature/TTS backend" recipes, test coverage map,
build instructions with MSVC env, git workflow with Forgejo NO_PROXY trick.
- Aimed at someone who just cloned the repo and needs to fix a bug fast.
Build: cargo build --release -p jarvis-app -p jarvis-gui both green.
Tests: 49/49 jarvis-core unit tests pass.
Big push driven by user feedback ("делай имбу") and web research on what
voice assistants need to be the ideal:
TTS backend abstraction (P0.1)
- new module crates/jarvis-core/src/tts/{mod,sapi,piper,silero}.rs
- TtsBackend trait with SapiBackend (current PowerShell), PiperBackend
(rhasspy/piper, neural quality), SileroBackend (python subprocess)
- JARVIS_TTS env var picks (sapi|piper|silero). Auto-detect Piper if
binary + voice present in tools/piper/. Falls back to SAPI on missing.
- SpeakOpts {lang, detached, raw} replaces ad-hoc args. text_utils
sanitiser applied unless raw=true.
- llm_fallback + lua/api/tts both routed through tts::backend().
- tools/piper/install.ps1 downloads piper.exe + ru_RU-irina-medium.onnx
from rhasspy releases + huggingface. Smoke-test included.
- tools/silero/silero_tts.py helper (PyTorch); rust spawns it as subprocess.
IMBA-1 Agentic LLM router
- crates/jarvis-app/src/llm_router.rs
- When fuzzy/intent matcher fails, LLM picks the closest command from the
full registry. Returns JSON {command_id, confidence, reason}.
- Threshold-gated re-dispatch via substitute phrase. JARVIS_LLM_ROUTER=1
enables; JARVIS_LLM_ROUTER_THRESHOLD overrides 0.55 default.
- Inserted in app.rs::execute_command between "no match" and existing
llm_fallback chat fallback.
IMBA-2 Long-term memory
- crates/jarvis-core/src/long_term_memory.rs — JSON store at
APP_CONFIG_DIR/long_term_memory.json. Atomic write-through.
- remember/recall/search/forget/all/build_context API.
- Lua bindings: jarvis.memory.* (5 functions).
- llm_fallback auto-injects relevant facts (substring search of prompt)
into system message before LLM call.
- Pack resources/commands/memory_pack/ with 4 commands: remember, recall,
forget, list.
IMBA-3 Profile switching (work/game/sleep/driving/default)
- crates/jarvis-core/src/profiles.rs — JSON profiles at APP_CONFIG_DIR/profiles/
Auto-seeds 5 defaults on first run with personality + allow/deny lists +
greetings + emoji icons.
- active_profile.txt persists choice across restart.
- Lua bindings: jarvis.profile.{active,set,list,allows,active_name}.
- llm_fallback prepends profile personality to system prompt.
- Pack resources/commands/profile_switch/ with 6 voice triggers.
IMBA-4 Multimodal screenshot + vision LLM
- crates/jarvis-core/src/lua/api/vision.rs — gated on HTTP sandbox.
- jarvis.vision.screenshot() captures via PowerShell System.Drawing.
- jarvis.vision.describe(prompt?) sends base64 PNG to Groq vision model
(default llama-3.2-11b-vision-preview, override via GROQ_VISION_MODEL).
- Pack resources/commands/vision/ with 2 commands: describe + read_error.
P0.2 Continuous conversation grace window
- config::CONVERSATION_GRACE_MS = 30_000.
- app.rs: after command result, if grace_ms > 0 keep listening WITHOUT
re-wake for the grace duration. Existing CMS_WAIT_DELAY back-dated so
the existing timeout fires at start + grace_ms.
Tests: 24/24 jarvis-core unit tests pass (including 5 text_utils).
Build: cargo build --release -p jarvis-app and -p jarvis-gui both succeed
on Windows MSVC (VS 2026 Enterprise vcvars64).
Notes for setup:
- Piper voice install: pwsh tools/piper/install.ps1 (downloads ~90 MB).
- GROQ_TOKEN needed for IMBA-1 (router) and IMBA-4 (vision).
- All features are opt-in via env vars or auto-detect; existing SAPI +
fuzzy match path remains the default.
User complaint: SAPI reads every dotted acronym character-by-character with a
"точка" between letters. Unbearable on every speak. No real TTS analog
shipping yet (Silero/Coqui/Inworld in roadmap), so the immediate fix is text
preprocessing.
New module `jarvis-core::text_utils` with `sanitize_for_speech()`:
- Specific brand mapping: J.A.R.V.I.S. → Джарвис, U.S.A. → США, U.K. →
Британия, U.S. → США, S.O.S. → сос.
- Generic dotted-acronym collapse: any `[letter].[letter].[letter].(...)`
run of 3+ letters gets its dots stripped. "T.O.N." → "TON".
- URL stripping: anything starting with http/https gets replaced with the
word "ссылка". SAPI reading URLs char-by-char is unlistenable.
- Em/en-dash normalisation: — → -, « » " stripped.
- Whitespace collapse.
Wired in two places:
- `jarvis.speak(text, opts?)` Lua API runs sanitiser unless opts.raw=true.
- `jarvis-app/llm_fallback::speak_via_sapi` runs sanitiser before the SAPI
PowerShell shell-out for LLM auto-fallback replies.
5 unit tests in `text_utils::tests` covering jarvis-name collapse, generic
acronym pattern, URL stripping, dash normalisation, and "leave clean
russian sentences alone" — all green.
Real TTS upgrade (Silero v4 first cut) tracked as P0.1 in roadmap.
Architecture — close the trigger-strip duplication:
lua/api/text.rs (new):
+ jarvis.text.strip_trigger(phrase, triggers) — case-insensitive
"longest trigger wins" stripping, returns trimmed remainder. The
11 packs that previously inlined a `for _, t in ipairs(triggers) do
string.find ... s == 1 then sub` loop can drop to one call.
Demonstrated in spelling/, window_switch/, summarize/.
+ jarvis.text.contains_any(phrase, needles) — boolean check for any
of N substrings, case-insensitive. Useful for keyword routing.
5 new portable Lua packs (sandbox=full). 36 → 41 total. cargo test
commands::tests still 3/3.
brightness/ — brightness_up / down / max / min. WMI WmiMonitorBrightness
(read CurrentBrightness) + WmiMonitorBrightnessMethods.WmiSetBrightness
(write). ±20% step for up/down; max=100, min=10. Desktop monitors that
don'\''t expose the WMI namespace get a friendly "не поддерживается"
toast instead of a silent failure.
window_switch/ — switch_to_window. Strip trigger ("переключись на" /
"switch to" / etc.), apply the same alias map as process_kill
(хром→chrome, телега→telegram, ...), then PowerShell finds processes
by name OR window-title substring sorted by StartTime desc and uses
(New-Object -ComObject WScript.Shell).AppActivate($pid) on the top
match. Speaks the window title that got focus.
spelling/ — spell_out. Strips "произнеси по буквам" / "spell out" /
etc., iterates `word:gmatch(".")`, joins letters with ". " so SAPI
gives each one a natural micro-pause. Uses jarvis.text.strip_trigger
+ jarvis.speak — 24 lines total.
network/ — open_wifi_settings (ms-settings:network-wifi) +
open_bluetooth_settings (ms-settings:bluetooth) + my_ip. my_ip pulls
the first non-loopback, non-APIPA IPv4 with Get-NetIPAddress and
fetches WAN IP from api.ipify.org (5s timeout); speaks "Локальный X.
Внешний Y".
summarize/ — summarize_selection. Synthesises Ctrl+C through user32!
keybd_event (so the focused window copies its selection), waits
220 ms for the clipboard to populate, reads via
jarvis.system.clipboard.get(), bails if < 20 chars, truncates at
8000, sends to Groq @ temp 0.3 with a "3-5 sentences, keep names"
prompt, drops the summary back into the clipboard and speaks it.
Lets you select ANY text in ANY app (browser, PDF, IDE) and say
"суммируй" to get a spoken TL;DR.
The new packs explicitly use the new jarvis.text + jarvis.llm +
jarvis.speak API surface — no inline PS-SAPI boilerplate, no inline
Groq plumbing. Code is now intent-first.
Architecture — DRY at the Lua API surface:
lua/api/tts.rs (new): jarvis.speak(text, opts?). opts.lang = ISO
two-letter code (default "ru"); auto-picks first installed voice
matching the culture. opts.async = true|false (default true). The
9 packs that previously inlined a 60-character PS-SAPI string for
every spoken reply can now reduce to one line. Refactored fun/,
dice/, clipboard_read/ as proof — fun/ask.lua went from 75 lines
of HTTP+SAPI boilerplate to ~28 lines of intent code.
lua/api/llm.rs (new): jarvis.llm(messages, opts?). messages is a
list of {role, content} tables, opts.max_tokens / .temperature /
.top_p. Returns the assistant string or nil. Gated by sandbox
allows_http() (so Standard+ packs only). Internally uses the
existing jarvis_core::llm::LlmClient::complete_with, no duplicated
HTTP plumbing.
llm/client.rs: split complete() into complete_with(messages,
max_tokens, temperature, top_p) for the new caller; old complete()
is now a thin wrapper at temp=0.7 top_p=1.0 for backward compat.
GUI — /commands page rewrite:
Replaces the "Раздел в разработке" placeholder. Calls Tauri command
get_commands_list (already existed in tauri_commands/commands.rs,
was wired but unused). Renders a search-filterable card grid:
- cmd id (monospace)
- type badge with colour by kind (lua=blue, ahk=red, cli=grey,
voice=green, terminate=red, stop_chaining=violet)
- sandbox badge
- description line (if non-empty)
- all phrases for currentLanguage, fallback to en, fallback to
first available; each phrase in a small inline pill
Toolbar: text input with magnifier icon + reload button (↻).
Counter line shows visible/total + "Скажи Джарвис + любую фразу"
hint. Counts down as you type the filter.
New packs (3, total 33 → 36):
games/ — launch_game / list_games. Reads or creates
%USERPROFILE%\Documents\jarvis-games.json (the sample preloads dota,
cs2, elden ring, witcher 3, factorio + minecraft launcher path +
fortnite epic URI). Trigger-strip + fuzzy name/alias match, then
launches via steam://rungameid/N (Steam), epic:// (Epic Games), or
start "" "path" (anything else). list_games speaks the configured
library.
mouse/ — left/right/middle/double click + scroll up/down. Single
dispatch.lua + _mouse_helper.ps1. PS P/Invokes user32!mouse_event
with the right flag pair (LEFTDOWN+LEFTUP / etc.), 30ms gap, doubles
do two LEFT cycles with a 50ms gap, wheel uses ±360 ticks.
random_choice/ — "выбери из X или Y или Z". Strips the trigger,
splits on " или " / " or " / ", " / " либо " / " чи ", math.random
picks one, speaks "Я выбираю N".
cargo test commands::tests still 3/3. 36 packs verified via
jarvis-gui startup log.
LLM auto-fallback (jarvis-app/src/app.rs + jarvis-core/src/config.rs):
- When neither intent classifier nor levenshtein finds a command match,
route the utterance straight to the LLM instead of just playing the
"not found" sound. Triggers ("скажи X", "answer Y") still work and
take precedence — they short-circuit before command lookup.
- Two new config knobs:
LLM_AUTO_FALLBACK = true — master toggle
LLM_AUTO_FALLBACK_MIN_CHARS = 4 — suppress for very short utterances
so background noise doesn't burn
Groq quota
- Requires GROQ_TOKEN; if absent, behaviour is unchanged (play_not_found).
codegen/ command pack:
- Phrases: "напиши код X", "сгенерируй скрипт Y", "write code Z", etc.
- Strips the trigger from the recognized phrase, sends what remains to
Groq with a strict system prompt ("return ONLY code, no fences, no
commentary") at temperature 0.2.
- Parses the JSON content, unescapes \n / \" / \\ / \t, strips any
remaining ```lang ... ``` fences, drops the result into the clipboard
via jarvis.system.clipboard.set.
- Notifies a 120-char preview + plays ok-sound. Works for any language
the model handles (Python by default if unspecified).
- GROQ_TOKEN / GROQ_MODEL / GROQ_BASE_URL read from env at call time —
same envvars the voice-loop fallback already uses.
ocr/ command pack:
- Phrases: "прочитай экран", "что на экране", "read screen", etc.
- Captures the primary screen via System.Windows.Forms + System.Drawing
to a temp PNG, then shells to tesseract.exe (-l rus+eng for ru/ua,
-l eng for en).
- Resolves Tesseract by PATH first, then C:\Program Files\Tesseract-OCR
and the x86 install dir; if none works the user gets a friendly
"winget install UB-Mannheim.TesseractOCR" hint in a notification.
- Recognized text goes to clipboard + a 200-char preview notification.
All three features are portable (env-var resolution, no hardcoded user
paths). Command-pack total is now 11. cargo test -p jarvis-core --lib
commands::tests passes 3/3.
Three unit tests catch the kind of bug that broke weather/set_city (a
phrases array instead of lang→array map silently dropped the whole pack):
- every_command_toml_parses: every resources/commands/*/command.toml round-
trips through toml::from_str::<JCommandsList>. Reports all failures at
once instead of failing on the first.
- lua_command_scripts_exist: for every type="lua" command, the named (or
default script.lua) script file exists in the pack dir.
- every_command_has_phrases: structural commands (terminate/stop_chaining)
excluded, every other command has ≥1 phrase across all languages.
Tests use env!("CARGO_MANIFEST_DIR") -> ../.. -> resources/commands so they
work from any cwd.
NB: cargo test does not run on this machine right now — aws-lc-sys needs
cl.exe (MSVC Build Tools missing). The release binary was built earlier
with MSVC available; toolchain install is a follow-up. The tests are still
valid for CI / a re-armed dev box.
new module crates/jarvis-app/src/llm_fallback.rs holds an optional
LlmClient + ConversationHistory built once at startup. if GROQ_TOKEN is
unset the module logs a warning and stays disabled — voice commands keep
working as before.
both the wake-word voice path (recognize_command in app.rs) and the
gui-side text command path (process_text_command) now check whether the
recognized phrase starts with one of the configured trigger phrases
(ru: 'скажи' / 'ответь' / 'произнеси'). when it does, the remainder of
the phrase is sent to Groq and the reply is published as a new
IpcEvent::LlmReply { text } so the gui can speak it.
on api error the trailing user turn is popped from history, the russian
fallback line is sent over ipc and a 'error' voice cue plays. the loop
itself never panics.
add LLM_DEFAULT_ENABLED / LLM_DEFAULT_MAX_HISTORY / LLM_DEFAULT_MAX_TOKENS
defaults, the russian J.A.R.V.I.S. system prompt, a fallback error line,
and per-language helpers get_llm_trigger_phrases() and get_llm_system_prompt()
so the voice loop can opt into Groq with a 'скажи …' style prefix.
split llm.rs into a module with separate client and history submodules.
ConversationHistory holds an optional system prompt plus a FIFO of user/
assistant turns capped at max_turns; oldest turns evict on overflow,
system prompt is preserved across truncation and clear().
New jarvis-core::llm module providing a blocking client for
OpenAI-compatible chat completions endpoints (Groq by default).
- LlmClient::new / from_env (GROQ_TOKEN, GROQ_BASE_URL, GROQ_MODEL)
- complete(messages, max_tokens) -> String
- thiserror-based LlmError / ConfigError
- gated behind a new llm feature, included in default jarvis_app
Not yet wired into the wake-word/intent loop; that lands in v0.3.
