feat(voice): flash ⚡ / default / think 🧠 modes + consent-gated gmail send#191
Merged
Conversation
Three modes on the live voice-to-voice chat, same interface
(docs/VOICE-MODES-DESIGN.md, operator-approved):
- flash: prefill-surgery for snappy turns — context trim 20→8 turns, skip
per-turn memory + observer injections, max_tokens 2000→400, one-sentence
rule, TTS 1.25x. Same local Qwen 35B.
- default: byte-identical to previous behavior.
- think: live multi-step tool calling — utterances route through a
voice-scoped codec_agents.Agent over a curated allowlist (hue, music,
chrome, web search/fetch, calendar, gmail, imessage, timers, reminders,
weather, notes). Each tool call is narrated over TTS (extended-wait
keepalive); speaking interrupts the loop; 6-tool + 120s budgets. Terminal/
python_exec/file_write etc. are hard-excluded and config-immune. The
single-skill fast path still fires first.
Switching: voice command ("flash/think/normal mode", terse-utterance guard so
"i think mode collapse…" can't hijack) + three UI pills on /voice + additive
WS {"type":"mode"} protocol. Kill switch VOICE_MODES_ENABLED. New audit event
voice_mode_changed (AGENTS.md §6 updated); think tool calls ride the existing
run_with_hooks audit chokepoint.
gmail: new consent-gated `send` action (think-mode "send an email" demo).
Strict Step-3 consent — CODEC reads the draft, only the literal spoken word
"send" sends; timeout/disabled/generic-yes fail CLOSED. gmail.modify scope
already covers send (no re-auth). Manifest regenerated (PR-1A).
Tests (TDD red-then-green): tests/test_voice_modes.py (11) +
tests/test_gmail_send.py (6). Full suite 2391 passed.
