Engine: streaming `_generate_reply` (`engine.py`) + +The graph stream runs on a **throwaway daemon producer thread** that pushes typed items +onto a `queue.Queue`; the reply worker thread consumes them.

The consumer's `queue.get` uses a `time.monotonic` deadline so the total-turn +timeout and its "took longer than {n}s to respond" message are unchanged +(`_REPLY_TIMEOUT_SECONDS` stays 60s). On timeout the producer is abandoned (daemon, dies +with the process) and a `CLIError(error_type="agent_timeout")` is raised, as today. + +Producer items: `ToolNotice`/`SpeechDelta` (forwarded from the brain), plus engine +sentinels `Done` and `Error(exc)`. + +Consumer loop, per item: + +- `ToolNotice(label)` → `renderer.tool_call(label)` **and clear the pending clause + buffer** (the "drop unspoken preamble on a tool call" decision).

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Give the `assembly live` voice agent a keyless, always-available weather tool (current conditions + short forecast) backed by Open-Meteo. + +**Architecture:** A new live-only module `aai_cli/agent_cascade/weather_tool.py` following the `fetch_tool.py` shape — pure, directly-tested helpers (WMO-code text, formatting) plus a single injectable network seam (`Fetcher = Callable[[str], object]`). The tool geocodes a place name, fetches a 3-day forecast, and renders a short speakable string. `brain.py` binds it into the deepagents graph, advertises it in the system prompt, and gives it a live-UI affordance label. + +**Tech Stack:** Python 3.12+, `httpx` (already a dependency, used by `fetch_tool.py`), LangChain `@tool`, `aai_cli.core.jsonshape` for safe JSON parsing, pytest. + +## Global Constraints + +Copied verbatim from the repo invariants — every task's requirements include these: + +- `from __future__ import annotations` at the top of every module; modern typing (`X | None`). +- mypy is **strict** on `aai_cli` (`disallow_untyped_defs`); no new `# type: ignore` / `Any` / `cast(` — the gate count-checks these against the merge-base. Parse untyped JSON through `aai_cli.core.jsonshape` (`as_mapping`, `mapping_list`, `object_list`, `as_int`, `as_float`) rather than indexing raw `object`. +- The tool is **keyless** — it must **not** read any env var (no `aai_cli.core.env` use, no API key); Open-Meteo needs none. +- Tests are **hermetic**: pytest-socket is armed (`--disable-socket`). Never make a real HTTP call in a test — always drive the tool through the injected `fetch` seam. +- The gate requires **100% patch coverage** vs `origin/main` **and** survives **diff-scoped mutation testing**: every changed line needs an assertion that would *fail* if the line broke (assert behavior, not just execution). A pure tuning constant that can't be asserted gets `# pragma: no mutate`. +- Docstrings on public functions are imperative, sentence-case; internal helper docstrings keep normal punctuation.

Today its toolset is +deliberately tiny and **read-only** (Firecrawl web search when keyed, plus opt-in +read-only MCP tools), because a spoken turn cannot pause for a keyboard +confirmation. Users want the agent to act on local files during a conversation +("read me notes.txt", "save that summary to summary.md") without leaving the voice +session. + +## Decisions (locked during brainstorming) + +1. **Opt-in, not default.** A new flag enables the capability; default behavior is + unchanged (tool-free / web-search-only). Mirrors the strictly-opt-in posture of + `--mcp-config`. +2. **Reads free, writes confirmed.** Read tools auto-approve; `write_file` / + `edit_file` require explicit confirmation. +3. **Confirmation is a TUI keypress (y/n).** A pending write pauses the turn and the + voice TUI shows the target path with a `y/n` prompt. Robust and unambiguous; + reuses `assembly code`'s interrupt/resume `Approver`. (Spoken yes/no was + considered and rejected as fragile and a larger change to the turn flow.) +4. **Files, not a shell.** Use `FilesystemBackend` (read/write/edit/ls/glob/grep), + **not** `LocalShellBackend` — so no `execute` tool is exposed. +5. **Rooted at the launch directory (cwd)**, with `virtual_mode=True` blocking + traversal escapes — identical containment to `assembly code`. + +### Open choices to confirm at spec review + +- **Flag name:** proposed `--files` (boolean). Alternatives: `--workdir`, + `--allow-files`. The root is always cwd for now (no path argument — YAGNI). +- **Read-tool gating:** reads ungated (`read_file` / `ls` / `glob` / `grep` + auto-approve). Only `write_file` / `edit_file` are confirmed. + +## Architecture + +### Toolset (reuse from `assembly code`) + +`assembly code` builds its graph over +`LocalShellBackend(root_dir=cwd, virtual_mode=True)`, which exposes both filesystem +tools **and** the `execute` shell tool. We instead use +`FilesystemBackend(root_dir=cwd, virtual_mode=True)` from `deepagents.backends`, +which provides `read`/`write`/`edit`/`ls`/`glob`/`grep` and **no** `execute`. Same +`virtual_mode` rooting: the model's `/`-rooted paths map under cwd and traversal +escapes are blocked. + +`aai_cli/agent_cascade/brain.py::build_graph` gains the backend when the feature is +enabled. Currently `build_graph` calls `create_deep_agent` with no backend (an +in-memory virtual filesystem); enabling files passes the real `FilesystemBackend`. + +### Approval (reuse `assembly code`'s interrupt/resume) + +When files are enabled, `build_graph`: + +- sets `interrupt_on={"write_file": True, "edit_file": True}` (reads are **not** + gated), and +- attaches an `InMemorySaver` checkpointer (interrupt/resume requires one) plus a + stable `thread_id` in the per-invoke config. + +The brain's completer (`build_completer` / `_run_graph`) gains an +interrupt-resolution loop modeled on `aai_cli/code_agent/session.py::_resolve_interrupts`: +on a write interrupt it calls an injected `Approver(name, args) -> bool` and resumes +the graph with an approve/reject `Command(resume=...)`, looping until the turn no +longer pauses. The `Approver` type and the resume-decision shape are lifted from the +code agent. + +When files are **disabled**, none of this is wired — `build_graph` behaves exactly +as today (no backend, no checkpointer, no interrupt_on). + +### Confirmation channel (front-end supplies the `Approver`) + +The `Approver` is injected from the front-end through `CascadeDeps`, so the engine +and brain stay testable against plain functions. + +- **Voice TUI (`LiveAgentApp`)** — interactive mic, human mode. A pending write + pauses the reply turn; the TUI surfaces the target path and a `y/n` prompt (a + small approval line/modal — the TUI already owns the keyboard via its `BINDINGS`). + The reply worker thread blocks on a `threading.Event` that the UI thread sets on + keypress, then resumes the graph — the same block-the-worker pattern the code + agent's TUI approver uses. +- **Plain / headless renderer** — file/URL input, `--json`, `-o text`, or non-TTY + (where `_should_use_tui` is false). No keyboard channel, so the approver + **auto-denies** writes (reads still work). The declined write is surfaced inline + so the turn explains itself rather than silently doing nothing. + +### Capability advertisement (system prompt) + +`brain.build_system_prompt` / `_tool_capabilities` already tailor the prompt to the +bound tools (so the agent never promises a capability it lacks). When the filesystem +tools are bound, add a phrase like "read and write files in your working directory" +to the capability clause. The existing `_SPOKEN_TAIL` still applies — replies stay +short, spoken, and markdown-free even though the agent can now write files. Tool +labels (`_TOOL_LABELS`, shown as the live "…" affordance) get speakable entries: +"Reading a file", "Writing a file", "Editing a file", "Listing files", +"Searching files". + +## Data flow (a write turn, TUI) + +1. User speaks → STT finalizes a turn → `CascadeSession.on_turn` starts a reply. +2. The reply worker drives the deepagents graph. The model calls `write_file`. +3. The graph **interrupts** (write is in `interrupt_on`). The completer's resolution + loop calls the injected `Approver` with `("write_file", {path, content, …})`. +4. The TUI approver hops to the UI thread, shows the path + `y/n`, and blocks the + worker on an `Event` until a keypress sets approve/reject. +5. The completer resumes the graph with the decision. On approve the file is written + under cwd; on reject the model is told the user declined (the code agent's + `_DECLINED` message pattern). +6. The graph finishes; the spoken reply streams out through TTS as usual. + +## Error handling + +- **Reply timeout vs. human think time.** The reply worker runs the graph under a + 60s wall-clock backstop (`_REPLY_TIMEOUT_SECONDS` in `engine.py`). Time spent + awaiting human approval must **not** count against that deadline, or a slow + keypress would cut off the write mid-turn. The design excludes approval-wait time + from the reply timeout (pause/restart the clock around the approval round-trip, or + restructure so the approval wait is not under the timed call). +- **Containment.** `virtual_mode=True` rejects paths that escape cwd; such a tool + call fails inside the graph and is surfaced like any other tool error (the existing + `brain._run_graph` wraps graph/tool failures as a `CLIError` shown in the + transcript). +- **Headless writes.** Auto-denied (above) — never a silent no-op. + +## Out of scope / minimal touch + +- **No shell.** `execute` is never bound; `FilesystemBackend` only. +- **No access outside cwd.** No path argument; root is always the launch directory. +- **Default unchanged.** Without the flag, `live` is exactly as today. +- **`--show-code`.** Verify whether the generated SDK snippet models the brain's + tools at all.

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Overlap LLM token generation, TTS synthesis, and playback in a live cascade turn so audio starts on the first clause instead of after the whole reply is generated. + +**Architecture:** The reply leg becomes a stream. `brain.build_streamer` drives the deepagents graph with `stream_mode="messages"` and yields `SpeechDelta`/`ToolNotice` events. The engine consumes them on the reply-worker thread (fed by a throwaway daemon producer thread + a `queue.Queue` that preserves today's wall-clock timeout), buffers token deltas, flushes complete clauses via a new `text.pop_clauses`, and synthesizes each clause with **streaming TTS** (`tts_session.synthesize(..., on_audio=...)`) so playback begins on its first audio frame. + +**Tech Stack:** Python 3.12–3.13, deepagents/langgraph (`graph.stream`), `langchain_core` message chunks, the streaming-TTS WebSocket in `aai_cli/tts/session.py`, `threading`/`queue`, pytest + syrupy. + +## Global Constraints + +Copied verbatim from the repo invariants (every task's requirements include these): + +- `from __future__ import annotations` at the top of every module; modern typing (`X | None`). +- Errors → stderr, data → stdout. Help/option copy is terse, imperative, sentence-case, **no trailing period** (not relevant here — no new flags — but keep docstrings periodful). +- **The gate is the source of truth.** `./scripts/check.sh` must print `All checks passed.` Notable diff-scoped gates: **100% patch coverage** vs `origin/main`, a **diff-scoped mutation gate** (a changed line needs a test that *fails* if the line breaks — not just coverage), **vulture** (no dead code — flags both unused new functions *and* code that becomes unused), **xenon** (function complexity ≤ B), the **500-line max file length**, and a **"no new escape hatches"** count gate (`# pragma: no mutate` / `# noqa` / `pragma: no cover` / `cast(` / `Any` counted against merge-base — a *net-new* one fails). The **Textual-module ≥90% coverage floor** also applies, but this change does not touch `tui.py`. +- **Commit discipline:** iterate with fast targeted `uv run pytest …`, then gate once at the end. Use `AAI_ALLOW_COMMIT=1 git commit …` for intermediate per-task WIP commits; the **final** commit must follow a full green `./scripts/check.sh` (the PreToolUse hook enforces this). End every commit message with `Co-Authored-By: Claude Opus 4.8 (1M context) `. +- Run every tool through `uv run`. +- **Escape-hatch budget is net-neutral by design:** Task 3 removes `_complete_within`'s `daemon=True # pragma: no mutate`; the new producer thread adds exactly one back. `_MIN_CLAUSE_CHARS` is pinned by a test (Task 1/3), so it needs **no** pragma. Do not introduce other new pragmas. +- **Do not touch `uv.lock`** — no dependency changes in this work. + +--- + +## File Structure + +- `aai_cli/agent_cascade/text.py` — add `pop_clauses` (pure incremental clause splitter). Keep `split_sentences`/`trim_history`. +- `aai_cli/agent_cascade/brain.py` — add `SpeechDelta`/`ToolNotice` + `build_streamer` + `_stream_graph` (messages-mode iteration with verbose logging).

Extend the protocol: + +- `begin_output()` — called when audible output starts. +- `end_output()` — called when the engine has finished enqueuing the last frame + of the speaking phase. + +Implementations: + +- `_DuplexPlayer` (audio.py) delegates to its `DuplexAudio.set_output_active` + (`begin_output` → `set_output_active(on=True)`, `end_output` → + `set_output_active(on=False)`). +- `NullPlayer` (file-driven / headless) — no-ops (no live mic; `pending()` is + always 0, so the drain term is moot there too). +- The cascade test fake player gains the two no-op/recording methods. + +### 3. `engine.py` `CascadeSession` — drive the hooks + +Mute around every audible phase, leaving the drain term to cover the tail: + +- **Greeting** (`greet`): `player.begin_output()` before `synthesize(greeting, + …)`, `player.end_output()` after it returns. The greeting audio keeps the mic + muted while it drains via the buffer term. +- **Reply** (`_consume` / `_generate_reply`): call `begin_output()` at the point + `started` flips True (the first audible clause — same place `reply_started()` + fires), and `end_output()` in the reply's teardown alongside + `_speaking.clear()` / `reply_done(...)`, so it runs on every exit path (clean + finish, barge-in, TTS/leg failure, timeout). +- **Thinking / tool calls produce no audio**, so the mic stays open during them + — the user can still speak while the agent thinks or runs a tool (no echo to + guard against there). Muting is strictly tied to *audible output*. + +`on_turn` is **unchanged**: with the mic fed silence during playback, STT simply +emits no interim/final turns then, so the existing barge-in code never fires on +echo.

(Kills a mutant dropping the `len(_out)>0` term.) +3. **User mute composes.** `set_listening(off)` alone still mutes; clearing + output-active does not un-mute a user-muted mic.

It needs no terminal: recording starts immediately and `dictate_exec._record` polls `signals.stop_on_terminate` between ~100 ms mic chunks for a SIGTERM, which finishes the utterance (clean exit 0) — so a hotkey tool like Hammerspoon can launch it as a background task and `kill -TERM`/`task:terminate()` to transcribe. SIGINT (Ctrl-C) still cancels (exit 130). Both boundaries (the stop latch, mic, HTTP) are injectable, so the suite never needs a real signal or microphone (`tests/test_dictate_exec.py` scripts the SIGTERM latch). Contrast `signals.terminate_as_interrupt` (used by `stream`/`agent`/`speak`), which routes SIGTERM into the *cancel* path instead. - **`agent/`** — full-duplex voice agent (mic in, TTS out via `voices.py`). -- **`agent_cascade/`** + `commands/agent_cascade/` — `assembly agent-cascade`: the same live terminal conversation as `assembly agent`, but **client-orchestrated** — `engine.run_cascade` wires Streaming STT → the LLM Gateway → streaming TTS itself instead of talking to the Voice Agent endpoint, mirroring what the `agent-cascade` `assembly init` template does server-side. **Sandbox-only** (streaming TTS has no prod host; guarded via `tts.session.require_available`). Reuses the agent slice's `DuplexAudio`/`AgentRenderer` and `core.client.stream_audio`/`core.llm.complete`/`tts.session.synthesize`; the three network legs are injected through `engine.CascadeDeps` (the `tts/session.py` seam) so the cascade — greeting, per-sentence TTS, barge-in, history window — is unit-tested against fakes with no sockets/mic/speaker. The LLM leg is a deepagents graph (`brain.py`); under `-v` (`debuglog.active()`) `brain._run_graph` *streams* that graph instead of `invoke`-ing it and logs each tool call/result/interim line as it lands (reusing `code_agent.events.message_events`), so a spoken turn that stalls mid-tool is debuggable — plain `invoke` runs the whole loop internally and `-v` would otherwise show only the httpx lines. **Front-end:** an interactive mic session in human mode runs a **voice-only Textual TUI** (`agent_cascade/tui.py`, `LiveAgentApp`) by default — there's no text input (you can't type to it), just a transcript + an animated voice bar tracking listening/thinking/speaking. It shares the `assembly code` TUI's chrome (`code_agent.banner` wordmark, `code_agent.messages` widgets, `code_agent.tui_status.voicebar_markup`/`VOICE_FRAMES`); the blocking `run_cascade` runs on a worker thread and reaches the UI through a `_TuiRenderer` (the `engine.Renderer` protocol) that hops each call onto the UI thread, and a quit calls `DuplexAudio.close` to end the mic iterator and unblock that worker. `_exec._should_use_tui` gates it: file/sample input, `--json`/`-o text`, and a non-TTY all fall back to the plain `AgentRenderer` line output. +- **`agent_cascade/`** + `commands/agent_cascade/` — `assembly agent-cascade`: the same live terminal conversation as `assembly agent`, but **client-orchestrated** — `engine.run_cascade` wires Streaming STT → the LLM Gateway → streaming TTS itself instead of talking to the Voice Agent endpoint, mirroring what the `agent-cascade` `assembly init` template does server-side. **Sandbox-only** (streaming TTS has no prod host; guarded via `tts.session.require_available`). Reuses the agent slice's `DuplexAudio`/`AgentRenderer` and `core.client.stream_audio`/`core.llm.complete`/`tts.session.synthesize`; the three network legs are injected through `engine.CascadeDeps` (the `tts/session.py` seam) so the cascade — greeting, clause-level streaming TTS, barge-in, history window — is unit-tested against fakes with no sockets/mic/speaker. The LLM leg is a deepagents graph (`brain.py`) streamed token-by-token via `brain.build_streamer` (`graph.stream(stream_mode="messages")`): the engine buffers `SpeechDelta`s, flushes complete clauses with `text.pop_clauses` (soft-separator clauses gated by `engine._MIN_CLAUSE_CHARS`), and synthesizes each clause with **streaming TTS** (`tts.session.synthesize(on_audio=…)`) so audio starts on the first frame instead of after the whole reply. The reply runs on a throwaway producer thread feeding a `queue.Queue` the worker drains under a monotonic deadline (the wall-clock backstop that replaced `_complete_within`), and an abandoned-on-timeout graph leg's langchain `ThreadPoolExecutor` worker is detached (`_detach_executor_threads_since`) so it can't wedge interpreter exit. A `ToolNotice` surfaces the "Searching the web…" affordance and drops any unspoken preamble. Under `-v` (`debuglog.active()`) `brain._stream_graph` logs each accumulated assistant line, tool call, and tool result as it streams. **Front-end:** an interactive mic session in human mode runs a **voice-only Textual TUI** (`agent_cascade/tui.py`, `LiveAgentApp`) by default — there's no text input (you can't type to it), just a transcript + an animated voice bar tracking listening/thinking/speaking. It shares the `assembly code` TUI's chrome (`code_agent.banner` wordmark, `code_agent.messages` widgets, `code_agent.tui_status.voicebar_markup`/`VOICE_FRAMES`); the blocking `run_cascade` runs on a worker thread and reaches the UI through a `_TuiRenderer` (the `engine.Renderer` protocol) that hops each call onto the UI thread, and a quit calls `DuplexAudio.close` to end the mic iterator and unblock that worker. `_exec._should_use_tui` gates it: file/sample input, `--json`/`-o text`, and a non-TTY all fall back to the plain `AgentRenderer` line output. - **`tts/`** + `commands/speak.py` — `assembly speak` synthesizes text to speech over the sandbox streaming-TTS WebSocket (`streaming-tts.sandbox000.…`). **Sandbox-only:** `session.is_available()` is false in production (empty `Environment.streaming_tts_host`), so the command exits 2 with a `--sandbox` hint. `session.synthesize` drives a Begin→Generate→Flush→Audio→Terminate protocol with an injectable `connect` for hermetic tests (mirrors `agent/session.py`); `audio.py` plays the PCM (default) or writes a WAV (`--out`). The single-voice default-playback path **streams**: `synthesize`'s `on_audio(chunk, sample_rate)` callback is wired to `audio.PcmPlayer.feed`, so speech starts on the first Audio frame (it opens the device lazily, since the rate is only known at Begin) instead of after the whole text — the win for a long `--url` page. `--out` (needs the full buffer) and the multi-voice dialogue path (`synthesize_dialogue` → `_output_audio` → buffered `play_pcm`) stay buffered; `synthesize` still returns the complete PCM for the summary regardless. - **`code_agent/`** + `commands/code/` — `assembly code`: a terminal coding agent (a bespoke port of langchain-ai/deepagents' `code` agent) that talks **only** to the LLM Gateway. `model.py` pins the model to `ChatOpenAI` against `llm_gateway_base`; `agent.py` builds the deepagents graph over a cwd-scoped `LocalShellBackend` (filesystem + shell tools), plus extra tools: the custom `assembly` CLI tool (`cli_tool.py`, runs `python -m aai_cli` with the key via child env, never argv), a URL `fetch_url` tool (`fetch_tool.py`), Firecrawl web search when `FIRECRAWL_API_KEY` is set (`firecrawl_search.py`, shared with the live voice agent), an `ask_user` tool routed through an `AskBridge` to the front-end (`ask_tool.py`), and best-effort docs MCP tools (`docs_mcp.py`). Middleware adds installed skills (`skills.py`) and long-term memory (`memory.py`), each over its own dedicated backend. Sessions persist via a SQLite checkpointer (`store.py`) keyed by `--session`, so conversations resume. Approval gates the mutating tools (write/edit/execute/`assembly`/`fetch_url`); the general-purpose `task` subagent comes from deepagents by default. `session.py` drives the graph turn-by-turn (interrupt/resume = human approval), emitting framework-agnostic `events.py` to either the Textual TUI (`tui.py`, modeled on deepagents-code: transcript + input + approval/ask modals + clipboard copy) or the Rich fallback (`render.py`). The whole orchestration is tested by driving the **real** graph with a fake `BaseChatModel` (`tests/test_code_agent.py`), so no network/TTY is needed. **Voice is the default front-end in an interactive TTY** (`voice.py` + `_exec._run_voice`): `VoiceSession.listen` captures one spoken turn over Streaming STT (gating the mic shut the instant a turn finalizes) and `VoiceSession.speak` reads each assistant reply back over streaming TTS. It runs the **Rich REPL** loop (not the keyboard TUI) with a voice `read_line` + a reply-speaking sink. Readback needs streaming TTS, so it's **sandbox-only** (`tts.session.is_available`); in production the mic input still works and replies stay on screen. A mic-less box degrades to typed input on the first `AUDIO_ERROR_TYPES` `CLIError`; `--no-voice` selects the TUI, and a non-TTY (pipe/CI) the headless loop. Both legs (STT/TTS) are injected like the cascade's, so `tests/test_code_voice.py` drives it with fakes — no mic/speaker/socket. - **`code_gen/`** — backs `--show-code` on `transcribe`/`stream`/`agent`: builds a ready-to-run Python SDK script from exactly the flags passed (no API key needed; generated code reads `ASSEMBLYAI_API_KEY`).

It shares the `assembly code` TUI's chrome (`code_agent.banner` wordmark, `code_agent.messages` widgets, `code_agent.tui_status.voicebar_markup`/`VOICE_FRAMES`); the blocking `run_cascade` runs on a worker thread and reaches the UI through a `_TuiRenderer` (the `engine.Renderer` protocol) that hops each call onto the UI thread, and a quit calls `DuplexAudio.close` to end the mic iterator and unblock that worker. `_exec._should_use_tui` gates it: file/sample input, `--json`/`-o text`, and a non-TTY all fall back to the plain `AgentRenderer` line output. **`--files`** (off by default) swaps the brain's default in-memory backend for a real-cwd deepagents `FilesystemBackend(virtual_mode=True)` (traversal-blocked, no shell — the always-bound `execute` stays inert without a sandbox backend) and gates `write_file`/`edit_file` via `interrupt_on` + an `InMemorySaver`; `brain._stream_gated` detects the post-stream interrupt (`graph.get_state(config).interrupts`), asks an injected `Approver`, and resumes with `Command(resume=…)`, bracketing the human wait in `ApprovalPause` events so `engine._consume` suspends its reply deadline. The voice TUI supplies the approver by reusing `code_agent.modals.ApprovalScreen` (`y`/`a`/`n`); headless runs auto-deny writes (`_exec._deny_writes`). Reads (incl. `grep`) stay ungated. - **`tts/`** + `commands/speak.py` — `assembly speak` synthesizes text to speech over the sandbox streaming-TTS WebSocket (`streaming-tts.sandbox000.…`). **Sandbox-only:** `session.is_available()` is false in production (empty `Environment.streaming_tts_host`), so the command exits 2 with a `--sandbox` hint. `session.synthesize` drives a Begin→Generate→Flush→Audio→Terminate protocol with an injectable `connect` for hermetic tests (mirrors `agent/session.py`); `audio.py` plays the PCM (default) or writes a WAV (`--out`). The single-voice default-playback path **streams**: `synthesize`'s `on_audio(chunk, sample_rate)` callback is wired to `audio.PcmPlayer.feed`, so speech starts on the first Audio frame (it opens the device lazily, since the rate is only known at Begin) instead of after the whole text — the win for a long `--url` page. `--out` (needs the full buffer) and the multi-voice dialogue path (`synthesize_dialogue` → `_output_audio` → buffered `play_pcm`) stay buffered; `synthesize` still returns the complete PCM for the summary regardless. - **`code_agent/`** + `commands/code/` — `assembly code`: a terminal coding agent (a bespoke port of langchain-ai/deepagents' `code` agent) that talks **only** to the LLM Gateway. `model.py` pins the model to `ChatOpenAI` against `llm_gateway_base`; `agent.py` builds the deepagents graph over a cwd-scoped `LocalShellBackend` (filesystem + shell tools), plus extra tools: the custom `assembly` CLI tool (`cli_tool.py`, runs `python -m aai_cli` with the key via child env, never argv), a URL `fetch_url` tool (`fetch_tool.py`), Firecrawl web search when `FIRECRAWL_API_KEY` is set (`firecrawl_search.py`, shared with the live voice agent), an `ask_user` tool routed through an `AskBridge` to the front-end (`ask_tool.py`), and best-effort docs MCP tools (`docs_mcp.py`). Middleware adds installed skills (`skills.py`) and long-term memory (`memory.py`), each over its own dedicated backend. Sessions persist via a SQLite checkpointer (`store.py`) keyed by `--session`, so conversations resume. Approval gates the mutating tools (write/edit/execute/`assembly`/`fetch_url`); the general-purpose `task` subagent comes from deepagents by default. `session.py` drives the graph turn-by-turn (interrupt/resume = human approval), emitting framework-agnostic `events.py` to either the Textual TUI (`tui.py`, modeled on deepagents-code: transcript + input + approval/ask modals + clipboard copy) or the Rich fallback (`render.py`). The whole orchestration is tested by driving the **real** graph with a fake `BaseChatModel` (`tests/test_code_agent.py`), so no network/TTY is needed. **Voice is the default front-end in an interactive TTY** (`voice.py` + `_exec._run_voice`): `VoiceSession.listen` captures one spoken turn over Streaming STT (gating the mic shut the instant a turn finalizes) and `VoiceSession.speak` reads each assistant reply back over streaming TTS. It runs the **Rich REPL** loop (not the keyboard TUI) with a voice `read_line` + a reply-speaking sink. Readback needs streaming TTS, so it's **sandbox-only** (`tts.session.is_available`); in production the mic input still works and replies stay on screen. A mic-less box degrades to typed input on the first `AUDIO_ERROR_TYPES` `CLIError`; `--no-voice` selects the TUI, and a non-TTY (pipe/CI) the headless loop. Both legs (STT/TTS) are injected like the cascade's, so `tests/test_code_voice.py` drives it with fakes — no mic/speaker/socket. - **`code_gen/`** — backs `--show-code` on `transcribe`/`stream`/`agent`: builds a ready-to-run Python SDK script from exactly the flags passed (no API key needed; generated code reads `ASSEMBLYAI_API_KEY`). diff --git a/aai_cli/agent_cascade/brain.py b/aai_cli/agent_cascade/brain.py index edf1d28c..8ba9f184 100644 --- a/aai_cli/agent_cascade/brain.py +++ b/aai_cli/agent_cascade/brain.py @@ -371,7 +371,13 @@ def flush_log() -> None: try: if gated: yield from _stream_gated( - graph, conversation, approver, config, verbose, pending, flush_log + graph, + conversation, + approver, + config, + verbose=verbose, + pending=pending, + flush_log=flush_log, ) else: for chunk, _m in graph.stream( @@ -394,6 +400,7 @@ def _stream_gated( conversation: list[ChatCompletionMessageParam], approver: Approver | None, config: dict[str, object] | None, + *, verbose: bool, pending: list[str], flush_log: Callable[[], None], diff --git a/docs/superpowers/plans/2026-06-22-live-file-readwrite.md b/docs/superpowers/plans/2026-06-22-live-file-readwrite.md index a9de80c0..cc656015 100644 --- a/docs/superpowers/plans/2026-06-22-live-file-readwrite.md +++ b/docs/superpowers/plans/2026-06-22-live-file-readwrite.md @@ -1,26 +1,19 @@ # `assembly live` File Read/Write Implementation Plan -> **⛔ BLOCKED — DO NOT IMPLEMENT AS WRITTEN (decided 2026-06-22).** -> This plan targets the blocking reply path (`build_completer` / `_run_graph` / -> `_drive_graph` / `_complete_within`).

From e19ba15e7942e3fc2799b2d586a8fa5c1cb0e7be Mon Sep 17 00:00:00 2001 From: Alex Kroman Date: Mon, 22 Jun 2026 14:24:03 -0700 Subject: [PATCH 049/102] fix(tests): mypy narrowing in live TUI toggle test; regenerate code-TUI snapshots The code-TUI visual goldens were stale from the in-flight tool-call/streaming work; regenerate them to match current rendering. Fix a mypy unreachable false-positive where an opaque Textual-binding mutation defeats is-True/is-False narrowing.

All five are **always +bound** (none needs an API key): four use keyless public APIs or pure local +computation, and `convert_units` additionally leans on the bundled `pint` +library for physical units (keyless frankfurter.app for currency). Each returns +output short enough to read aloud, extending the existing weather / read-url / +datetime trio toward "talk to a multimodal assistant" parity — with no API-key +setup for the user. + +The five tools: + +1. `look_up_topic` — Wikipedia REST summary ("who is…", "what is…", "tell me about…"). +2. `calculate` — pure, safe arithmetic ("what's 15% of 240", "split 87 three ways"). +3. `convert_units` — physical units (via `pint`) + currency (via keyless frankfurter.app). +4. `define_word` — dictionary definition + synonyms (dictionaryapi.dev, keyless). +5. `get_time_in` — current local time in a named place (Open-Meteo geocode → `zoneinfo`). + +## Context + +`assembly live` answers each spoken turn with a deepagents graph +(`aai_cli/agent_cascade/brain.py`). Its built-in tools today are `get_weather`, +`read_url`, and `get_current_datetime` (all keyless, always present) plus +`firecrawl_search` (bound only when `FIRECRAWL_API_KEY` is set). The only path +to "tell me about X" today is the *keyed* Firecrawl search; `look_up_topic` +closes that gap keylessly. + +Tools are LangChain `BaseTool`s. The established pattern for a custom tool is +`aai_cli/agent_cascade/weather_tool.py` (and `datetime_tool.py`, +`webpage_tool.py`): pure, directly-testable helpers plus at most one thin seam +(a `Callable`) injected in tests so the suite needs no sockets/clock, and a tool +body that **never raises** — it catches its own failures and returns a short +spoken apology so a single tool outage can't sink a live turn. + +## Scope + +- **Live-only.** All five modules live in `aai_cli/agent_cascade/` and are bound + only in the live voice agent. The coding agent's toolset is unchanged. +- **Keyless-first.** `look_up_topic`, `define_word`, and `get_time_in` use + keyless public APIs; `calculate` needs no network; `convert_units` uses + keyless frankfurter.app for currency and the bundled `pint` library for + physical units. No new environment variables. +- **Speakable output.** Each tool returns one short string suitable for TTS. + +### Out of scope (YAGNI) + +- No per-tool opt-out flags — the tools are read-only and cheap; they are always + bound (no key gate, since none needs a key). +- No disambiguation UI anywhere — `look_up_topic` and `get_time_in` take the top + match; ambiguity is handled in the spoken reply, not a prompt. +- No locale/units configuration — `convert_units` converts exactly the units the + model names; `calculate` returns a plainly-formatted number. + +## Dependency: `pint` (separate PR) + +`convert_units`'s physical-unit path uses [`pint`](https://pint.readthedocs.io/). +Per the repo rule that dependency/`uv.lock` changes ship in their own +single-purpose PR, `pint` is added in **PR-A** (dependency only), and the feature +**PR-B** lands on top of it. + +- Add `pint` to `[project.dependencies]` in `pyproject.toml` + regenerate + `uv.lock`. +- Heed the safe-chain version-floor caveat: pin the floor to the second-newest + release, or resolution fails under the age gate. +- `pint` is imported **lazily** inside `convert_units` (it is a non-trivial + import) so it never slows CLI startup — matching `webpage_tool`'s lazy + `core.webpage` import. + +## Shared component: `geocode.py` (refactor) + +Both `weather_tool` and `get_time_in` resolve a spoken place name to +coordinates via Open-Meteo's keyless geocoding endpoint, and `get_time_in` +additionally needs the IANA `timezone` field that endpoint already returns. + +A new module `aai_cli/agent_cascade/geocode.py` factors this out: + +- `Fetcher = Callable[[str], object]` — GETs a URL → parsed JSON (the existing + weather-tool seam shape). +- `GeoResult` — `(name: str, latitude: float, longitude: float, timezone: str)`. +- `geocode(name, *, fetch) -> GeoResult | None` — query + `https://geocoding-api.open-meteo.com/v1/search?name=&count=1&language=en&format=json`, + return the top match (now including `timezone`), or `None` when there is no + match. + +`weather_tool._geocode` is refactored to delegate to `geocode.geocode` (it +ignores the extra `timezone` field). This keeps one geocoding implementation and +gives `get_time_in` the timezone it needs. The weather tool's public behavior +and its `format_report`/`describe_weather_code` helpers are unchanged; only the +internal geocode call moves. + +## The five tools + +Each is a new module beside `weather_tool.py`. All expose exactly two public +names: the `*_TOOL_NAME` constant and the `build_*_tool(...)` factory. + +### 1. `topic_tool.py` — `look_up_topic` + +- `LOOKUP_TOOL_NAME = "look_up_topic"`. +- Seam: `Fetcher` (the weather-tool shape). Default `_get_json` uses `httpx`. +- Endpoint: `https://en.wikipedia.org/api/rest_v1/page/summary/` with the + title URL-encoded. The response carries `extract` (a clean ~1-paragraph plain + text purpose-built to read aloud), `title`, and `type`. +- `build_lookup_tool(fetch=_get_json)` exposes + `look_up_topic(topic: str) -> str`: fetch, return the `extract`, capped to a + speakable length (`_MAX_CHARS`, `# pragma: no mutate` — a tuning knob). +- Failure → apology: + - `type == "disambiguation"` or empty `extract` → *"I couldn't find a clear + summary for '<topic>'."* + - 404 / HTTP / network error (the `fetch` seam raises) → *"I couldn't look + that up right now."* + +### 2. `calc_tool.py` — `calculate` + +- `CALC_TOOL_NAME = "calculate"`. +- **No seam — fully deterministic and offline** (the only tool with no + non-determinism, so no injected callable). +- A safe `ast`-based evaluator: `ast.parse(expr, mode="eval")`, then a recursive + walk that permits only `Expression`, `BinOp` over `+ - * / // % **`, + `UnaryOp` over `+ -`, parentheses (implicit in the AST), and numeric + constants. Any other node (`Name`, `Call`, `Attribute`, `Subscript`, …) is + rejected. The `**` exponent is bounded (reject an exponent above a small cap) + so `2 ** 99999999` can't wedge a turn. +- `build_calc_tool()` exposes `calculate(expression: str) -> str`.

17 00:00:00 2001 From: Alex Kroman <alex@assemblyai.com> Date: Mon, 22 Jun 2026 14:57:17 -0700 Subject: [PATCH 054/102] feat(models): default streaming, live, and batch to universal-3-5-pro Point the realtime defaults at the new universal-3-5-pro model: - stream: DEFAULT_SPEECH_MODEL -> SpeechModel.universal_3_5_pro - live (agent cascade): DEFAULT_SPEECH_MODEL -> "universal-3-5-pro" Batch transcribe defaults to universal-3-5-pro too, delivered via the plural speech_models list field since it is not in the SDK's SpeechModel enum; an explicit --speech-model / --config still wins. Sync STT (dictate) is left on u3-sync-pro (no 3.5 sync model).

The single-voice default-playback path **streams**: `synthesize`'s `on_audio(chunk, sample_rate)` callback is wired to `audio.PcmPlayer.feed`, so speech starts on the first Audio frame (it opens the device lazily, since the rate is only known at Begin) instead of after the whole text — the win for a long `--url` page. `--out` (needs the full buffer) and the multi-voice dialogue path (`synthesize_dialogue` → `_output_audio` → buffered `play_pcm`) stay buffered; `synthesize` still returns the complete PCM for the summary regardless. -- **`code_agent/`** + `commands/code/` — `assembly code`: a terminal coding agent (a bespoke port of langchain-ai/deepagents' `code` agent) that talks **only** to the LLM Gateway. `model.py` pins the model to `ChatOpenAI` against `llm_gateway_base`; `agent.py` builds the deepagents graph over a cwd-scoped `LocalShellBackend` (filesystem + shell tools), plus extra tools: the custom `assembly` CLI tool (`cli_tool.py`, runs `python -m aai_cli` with the key via child env, never argv), a URL `fetch_url` tool (`fetch_tool.py`), Firecrawl web search when `FIRECRAWL_API_KEY` is set (`firecrawl_search.py`, shared with the live voice agent), an `ask_user` tool routed through an `AskBridge` to the front-end (`ask_tool.py`), and best-effort docs MCP tools (`docs_mcp.py`). Middleware adds installed skills (`skills.py`) and long-term memory (`memory.py`), each over its own dedicated backend. Sessions persist via a SQLite checkpointer (`store.py`) keyed by `--session`, so conversations resume. Approval gates the mutating tools (write/edit/execute/`assembly`/`fetch_url`); the general-purpose `task` subagent comes from deepagents by default. `session.py` drives the graph turn-by-turn (interrupt/resume = human approval), emitting framework-agnostic `events.py` to either the Textual TUI (`tui.py`, modeled on deepagents-code: transcript + input + approval/ask modals + clipboard copy) or the Rich fallback (`render.py`). The whole orchestration is tested by driving the **real** graph with a fake `BaseChatModel` (`tests/test_code_agent.py`), so no network/TTY is needed. **Voice is the default front-end in an interactive TTY** (`voice.py` + `_exec._run_voice`): `VoiceSession.listen` captures one spoken turn over Streaming STT (gating the mic shut the instant a turn finalizes) and `VoiceSession.speak` reads each assistant reply back over streaming TTS. It runs the **Rich REPL** loop (not the keyboard TUI) with a voice `read_line` + a reply-speaking sink. Readback needs streaming TTS, so it's **sandbox-only** (`tts.session.is_available`); in production the mic input still works and replies stay on screen. A mic-less box degrades to typed input on the first `AUDIO_ERROR_TYPES` `CLIError`; `--no-voice` selects the TUI, and a non-TTY (pipe/CI) the headless loop. Both legs (STT/TTS) are injected like the cascade's, so `tests/test_code_voice.py` drives it with fakes — no mic/speaker/socket. - **`code_gen/`** — backs `--show-code` on `transcribe`/`stream`/`agent`: builds a ready-to-run Python SDK script from exactly the flags passed (no API key needed; generated code reads `ASSEMBLYAI_API_KEY`). - **`auth/`** — browser-assisted `assembly login` via AMS + **Stytch B2B OAuth discovery** (`discovery.py`, `flow.py`, `loopback.py`, `ams.py`). Not Stytch Connected Apps. - **`init/`** — scaffolds a self-contained FastAPI + HTML starter (`audio-transcription`/`live-captions`/`voice-agent` templates), optionally installs deps and opens the browser; writes the key to a git-ignored `.env`. diff --git a/tests/test_live_modals.py b/tests/test_live_modals.py index 80986d59..0a1653a8 100644 --- a/tests/test_live_modals.py +++ b/tests/test_live_modals.py @@ -2,7 +2,7 @@ The ``ApprovalScreen`` keyboard path is driven through the real Textual app headless.

Today that tool is bound but +inert: `--files` uses a plain `FilesystemBackend`, which is not a +`SandboxBackendProtocol`, so `execute` only returns an error. We make `execute` +real, but confine it to an OS-kernel-isolated, throwaway workspace so a spoken +turn can run arbitrary shell **without** a confirmation prompt and without any +risk to the user's machine or files. + +## Context + +`assembly live` answers each spoken turn with a deepagents graph +(`aai_cli/agent_cascade/brain.py`). Tools are normally auto-approved — a +low-latency spoken turn can't pause for a keyboard confirmation. The `--files` +flag is the one exception: it swaps the in-memory backend for a real-cwd +`FilesystemBackend(virtual_mode=True)` and gates `write_file`/`edit_file` behind +a TUI `y/a/n` approval (`brain._stream_gated` + `agent_cascade.modals`). Reads +(incl. `grep`) stay ungated. + +deepagents adds the `execute` tool automatically when the backend implements +`SandboxBackendProtocol`; for non-sandbox backends the tool returns an error +("inert"). The shipped options are `LocalShellBackend` (unrestricted host shell +— deepagents explicitly warns against untrusted/auto-approved use) or a +`BaseSandbox` subclass that implements `execute()` against real isolation. The +codebase already anticipates `execute`: `brain.py` comments call it +"always-bound … inert", and `risk.py` carries dormant shell-risk scoring for it. + +There is **no first-class Python library** for macOS sandboxing. The idiomatic +mechanism is `sandbox-exec -p '<SBPL profile>' <command>` (Apple Seatbelt, +still shipping on current macOS, used by AI coding-agent sandboxes); on Linux +the equivalent is the `bwrap` (bubblewrap) binary. Both are pure-subprocess +patterns — no new dependency — which fits this repo (it already shells out to +controlled subprocesses; `S603/S607` are ignored project-wide for this). + +## Decisions + +1. **Isolation:** OS-level sandbox. `sandbox-exec -p '<SBPL>'` on macOS, + `bwrap` on Linux. **Inert (safe refusal) on every other platform or when the + sandbox binary is missing — never a fallback to unconfined execution.** +2. **Scope:** general shell — deepagents' native `execute(command)`. +3. **Activation:** folded into the existing `--files` flag (no new flag). +4. **Workspace:** file tools stay rooted at the **real cwd** (unchanged from + today); `execute` runs in an **ephemeral `/tmp/aai-live-XXXX`**, fully + isolated — it cannot read the cwd, has no network, is time-bounded, and is + deleted on session exit. +5. **Gating:** keep today's TUI approval for `write_file`/`edit_file` (they + touch real files); `execute` runs **unprompted** — the sandbox is the + boundary. + +### Why these, over the alternatives (rejected) + +- **`LocalShellBackend` unconfined + approve every `execute`** — rejected: + approving shell commands by voice/TUI is clumsy, and deepagents itself warns + the backend gives no isolation. The sandbox lets us drop the friction safely. +- **Docker / container sandbox** — rejected: a heavy daemon dependency and slow + per-session cold start for a keyless CLI voice agent. +- **`execute` reads the real cwd (read-only)** — rejected in favor of full + isolation: a read-only cwd would expose the user's project (including `.env` + / secrets) to executed code. The model copies any needed data into the + scratch workspace instead. + +## Scope + +- **Live-only.** All new code lives in `aai_cli/agent_cascade/`; the change is + gated behind `--files`. Nothing else in the CLI changes. +- **No new dependency.** Pure subprocess over OS-provided binaries. +- **Speakable contract preserved.** `execute` never raises into the graph; on + any failure it returns a short string for the agent to speak. + +### Out of scope (YAGNI) + +- Windows sandboxing → `execute` stays inert there. +- Docker / remote / cloud sandboxes. +- Network access or package installation inside the sandbox. +- Persisting the scratch workspace across sessions or turns. +- Per-tool opt-out flags; a separate `--sandbox`/`--exec` flag. + +## Architecture + +### New module: `aai_cli/agent_cascade/sandbox.py` + +The entire sandbox concern in one focused, independently-testable module. + +- **`class SandboxedShellBackend(LocalShellBackend)`** — inherits + `FilesystemBackend` file operations rooted at cwd (so + `read_file`/`write_file`/`edit_file`/`ls`/`glob`/`grep` behave exactly as + `--files` does today) and **overrides `execute()`** so it never delegates to + the inherited host-shell `execute`. Implementing `SandboxBackendProtocol` (via + `LocalShellBackend`) is what makes deepagents auto-add the `execute` tool. + - `execute(command, *, timeout=None) -> ExecuteResponse`: resolve capability → + render the policy → run the wrapped command through the injected `Runner` + with `cwd=<scratch>` → return combined stdout + exit code as + `ExecuteResponse`.

The model copies any needed data into the scratch workspace instead. +- **Ephemeral scratch dir / fully isolated from cwd** — rejected: that is "run + arbitrary code safely," not cowork.

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Make `assembly live --files` able to run shell commands in the real cwd, OS-sandbox-confined (can't reach the network or escape cwd) and human-approved per run, and remember its work across sessions via a per-project memory file. + +**Architecture:** One new focused module `aai_cli/agent_cascade/sandbox.py` holds the entire sandbox concern: a `SandboxedShellBackend(LocalShellBackend)` whose `execute()` never delegates to the unconfined host shell but instead wraps the command in an OS sandbox (`sandbox-exec` SBPL on macOS, `bwrap` on Linux, refuse on every other platform / missing binary), driven by pure policy renderers and injectable `Runner`/capability seams so the suite is hermetic. `brain.py` swaps its filesystem backend for this one (which makes deepagents auto-add a *functional* `execute` tool), adds `execute` to the existing approval gate, and turns on `MemoryMiddleware` via `memory=["./.deepagents/AGENTS.md"]`. + +**Tech Stack:** Python 3.12+, deepagents + langgraph, Typer/Textual, pytest + syrupy, `uv`.

Do **not** touch `uv.lock`. +- **Live-only.** All new code lives in `aai_cli/agent_cascade/`; everything is gated behind `--files`. The `--files`-off path must be byte-for-byte unchanged. +- **Inert (safe refusal), never a fallback to unconfined execution.** On any platform other than macOS/Linux, or when the sandbox binary is missing, capability is `"none"` and `execute` returns a refusal string and **runs nothing**. The override must **never** call `super().execute()` (the unconfined host shell). This refuse-don't-fall-back branch is the single most safety-critical line. +- **`execute` never raises into the graph** — on any failure it returns a short string for the model to speak (the never-raise contract every live tool follows). +- **Errors → stderr, data → stdout** (repo invariant; not directly relevant here but preserve it). +- **Help copy is terse, imperative, sentence-case, no trailing period** (Codex-CLI style). Help strings are pinned by syrupy `--help` goldens — regenerate with `--snapshot-update`, never hand-edit `.ambr`. +- **`subprocess` is fenced by ruff `TID251`.** `sandbox.py` needs a deliberate per-file allowlist entry in `pyproject.toml`. Build the child env via `aai_cli/core/env.child_env`. +- **Max file length is 500 lines** (`scripts/max_file_length.py`) — keep `sandbox.py` under it. +- **Gate reality (from memory + `CLAUDE.md`):** `./scripts/check.sh` enforces **100% patch coverage vs `origin/main`** *and* a **diff-scoped mutation gate** — a changed boolean/string/branch survives unless a test asserts the behavioral *difference* between its two values, not merely that the line ran. There is also a **no-new-escape-hatches** gate (no net-new `# type: ignore`/`# noqa`/`pragma: no cover`/`Any`/`cast(`/test skip/xfail/sleep vs merge-base). `# pragma: no mutate` is the sanctioned way to exempt a genuinely unassertable tuning literal (use it for the `ulimit` caps only). +- **Commit hook:** a PreToolUse hook blocks `git commit` unless `./scripts/check.sh` last passed for the current working-tree signature. Use `AAI_ALLOW_COMMIT=1 git commit …` for the per-task WIP commits below, then run the **full** `./scripts/check.sh` once at the end (Task 7) and let that gate the final state. +- **Workspace:** execute on the current `live-tool-call-ux` branch (it already carries this feature's design docs).

The single-voice default-playback path **streams**: `synthesize`'s `on_audio(chunk, sample_rate)` callback is wired to `audio.PcmPlayer.feed`, so speech starts on the first Audio frame (it opens the device lazily, since the rate is only known at Begin) instead of after the whole text — the win for a long `--url` page. `--out` (needs the full buffer) and the multi-voice dialogue path (`synthesize_dialogue` → `_output_audio` → buffered `play_pcm`) stay buffered; `synthesize` still returns the complete PCM for the summary regardless. - **`code_gen/`** — backs `--show-code` on `transcribe`/`stream`/`agent`: builds a ready-to-run Python SDK script from exactly the flags passed (no API key needed; generated code reads `ASSEMBLYAI_API_KEY`). - **`auth/`** — browser-assisted `assembly login` via AMS + **Stytch B2B OAuth discovery** (`discovery.py`, `flow.py`, `loopback.py`, `ams.py`).

Defer the reply widget to the first streamed sentence (show_agent_sentence already mounts lazily) so the answer always lands below every tool affordance, with no placeholder gap. Also replace the brittle recursion cap with a per-turn tool-call budget: ToolCallLimitMiddleware(run_limit=CascadeConfig.tool_call_limit=10, exit_behavior="continue") wired into the deepagents middleware stack. Once the budget is hit, further tool calls are blocked and the model is forced to answer with what it gathered — a graceful stop instead of GraphRecursionError surfaced as a raw turn error. langgraph's own recursion_limit rides the deepagents default as a far-off safety net.

From b76ed28ecc3cfb10c8a3acac4dcc371b12d8ee92 Mon Sep 17 00:00:00 2001 From: Alex Kroman <alex@assemblyai.com> Date: Mon, 22 Jun 2026 19:27:25 -0700 Subject: [PATCH 089/102] Add honesty and file-safety guidance to live agent prompt Apply two principles to the live cascade's generated guidance layer: - Faithful reporting: whenever tools are bound, tell the model not to claim an action happened until the tool returns, and to admit failures briefly instead of inventing an answer. - Reversibility/consent: under --files, warn that file writes and code execution can't be undone, so confirm out loud before destructive actions and never narrate a change as done before it lands. Both live in build_system_prompt (tool-aware, non-overridable) rather than the user-overridable persona. Adds tests pinning each behavior.

The single-voice default-playback path **streams**: `synthesize`'s `on_audio(chunk, sample_rate)` callback is wired to `audio.PcmPlayer.feed`, so speech starts on the first Audio frame (it opens the device lazily, since the rate is only known at Begin) instead of after the whole text — the win for a long `--url` page. `--out` (needs the full buffer) and the multi-voice dialogue path (`synthesize_dialogue` → `_output_audio` → buffered `play_pcm`) stay buffered; `synthesize` still returns the complete PCM for the summary regardless. - **`code_gen/`** — backs `--show-code` on `transcribe`/`stream`/`agent`: builds a ready-to-run Python SDK script from exactly the flags passed (no API key needed; generated code reads `ASSEMBLYAI_API_KEY`). - **`auth/`** — browser-assisted `assembly login` via AMS + **Stytch B2B OAuth discovery** (`discovery.py`, `flow.py`, `loopback.py`, `ams.py`).

The production impl reads from the live STT leg (a queue the `on_turn` final-transcript path feeds during a pause); tests inject a fake that returns a scripted phrase or None — **no mic, no sockets** (mirrors the existing `CascadeDeps` fakes). +- The voice-aware approver: when invoked, it (1) consults `risk.risk_warning(name, args)` — if it fires (destructive tier), **ignore voice, require the keyboard** (delegate to the existing keypress approver); else (2) races the spoken-token source against the keypress, resolving with whichever lands first: a spoken token → `interpret_spoken_approval(token)`; a keypress → its decision; timeout/None/ambiguous → reject (the existing `_DECLINED` path). +- Keep `modals.ApprovalScreen` (keypress) as the fallback and the floor for the destructive tier; `_deny_writes` (headless) unchanged. + +### Task B — wire it through `_exec.py` / `tui.py` +- The TUI run currently passes `approver=approve_write` (keypress). Wrap it in the voice-aware approver, handing it the spoken-token source (from the engine's STT leg) and the keypress approver as the fallback. The destructive-tier branch routes to `approve_write` (keyboard) directly. +- Surface the spoken-vs-keyboard affordance on `ApprovalScreen` copy ("say 'approve' or press y") — regenerate the TUI snapshot if the modal chrome changes. + +### Task C — tests (hermetic, via the injected seams) +- An explicit affirmative phrase from the fake token source approves; a bare "yes", a negative, an unrecognized utterance, and a timeout each reject; a keypress still approves; and a `risk.py`-flagged destructive command **ignores** the spoken affirmative and requires the keypress. Assert the *resolved decision*, not mere execution (kills the mutation-gate mutants on the race/risk branches). +- `risk.py`'s destructive branch is exercised by the destructive-tier test (it's already covered by `tests/test_live_risk.py`). + +## Constraints (carry from M1/M2) +- Hermetic: inject the spoken-token source + keypress; no mic/sockets. `from __future__ import annotations`; no new dependency. +- Fail-safe to reject is the invariant: every non-clear-affirmative path → reject. +- 100% patch coverage + mutation gate; no new escape hatches; tests-pyright via `-p pyrightconfig.tests.json` (add the file to its ignore list if it builds real deepagents graphs). +- Concurrent session churns `engine.py`/`tui.py`: commit only M3 files; `AAI_ALLOW_COMMIT=1` per task; final `./scripts/check.sh` (sandbox-disabled).

The single-voice default-playback path **streams**: `synthesize`'s `on_audio(chunk, sample_rate)` callback is wired to `audio.PcmPlayer.feed`, so speech starts on the first Audio frame (it opens the device lazily, since the rate is only known at Begin) instead of after the whole text — the win for a long `--url` page. `--out` (needs the full buffer) and the multi-voice dialogue path (`synthesize_dialogue` → `_output_audio` → buffered `play_pcm`) stay buffered; `synthesize` still returns the complete PCM for the summary regardless. - **`code_gen/`** — backs `--show-code` on `transcribe`/`stream`/`agent`: builds a ready-to-run Python SDK script from exactly the flags passed (no API key needed; generated code reads `ASSEMBLYAI_API_KEY`). - **`auth/`** — browser-assisted `assembly login` via AMS + **Stytch B2B OAuth discovery** (`discovery.py`, `flow.py`, `loopback.py`, `ams.py`).
