What is blurt AGENTS.md?

A set of instructions for Blurt, an on-device voice-to-text app for Apple Silicon Macs. Voice recordings are transcribed locally and pasted where the cursor is.

Use it when installing, running, testing, formatting, releasing, or changing the single-file Blurt application.

It gives coding agents the project's operating details, commands, architecture, and release process so they can work without guessing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00729	$0.00729
Opus 5.5	$0.00292	$0.00292
Sonnet 5.5	$0.00146	$0.00146
Haiku 4.5	$0.00073	$0.00073

Security

Grade A, and why

blurt AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What is Blurt

On-device voice-to-text for macOS Apple Silicon. Single-file Python app - press right ⌘ to start, press it again to stop, and text pastes at the cursor. Uses Qwen3-ASR through MLX locally, no cloud/API.

Commands

# Dev install
uv pip install -e ".[dev]"

# Run
blurt

# Tests
pytest
pytest tests/test_blurt.py::test_get_model_mode_default  # single test

# Lint
ruff check .
ruff format .

# Release (tags + pushes, triggers PyPI publish via CI)
./release.sh 0.5.0

Requires portaudio system dep (brew install portaudio).

Architecture

Single package: blurt/__init__.py contains everything. No submodules.

Flow: main() → starts pynput keyboard listener → successive shortcut presses toggle start_recording() and stop_recording() → stopped audio is concatenated and saved to ~/.blurt/audio/ → the selected Qwen3-ASR model transcribes it → pbcopy+osascript pastes it → the transcript is logged to ~/.blurt/blurts.jsonl.

Key design details:

The fast (Qwen3-ASR-0.6B-8bit) and accurate (Qwen3-ASR-1.7B-8bit) models are lazy-loaded and pre-warmed in a background thread at startup
Transcription paste works by saving/restoring clipboard (pbcopy/pbpaste) and simulating ⌘V via osascript
Silence is filtered using audio amplitude and RMS thresholds; prompt echo and repetition detection filter unsafe output before paste
Global mutable state (recording, audio_buffer, stream, etc.) protected by threading.Lock
Versioning via setuptools-scm (git tags), no hardcoded version
Sound feedback files bundled in blurt/sounds/*.mp3

CLI Subcommands

blurt (run), blurt add <phrase>, blurt rm <phrase>, blurt vocab (list words), blurt log (view transcripts), blurt upgrade (self-update via pipx).

Vocab

~/.blurt/vocab.txt - one word/phrase per line. Passed to Qwen as transcription context to bias recognition.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
