What is sflow CLAUDE.md?

A historical development guide for SFlow v1/v2, a macOS voice-to-text app that records speech through keyboard shortcuts, sends it to the Groq Whisper transcription service, and pastes the text where the cursor is.

Use it only as a reference for the older Python app's setup and behavior; new SFlow work should use the sflow-next project described in the guide.

It prevents developers from working on an old Python version when current SFlow development belongs in the separate Swift-based v3 project.

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	$0.04518	$0.04518
Opus 5.5	$0.01807	$0.01807
Sonnet 5.5	$0.00904	$0.00904

Security

Grade A, and why

sflow CLAUDE.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.

CLAUDE.md — SFlow Development Instructions

⚠️ ESTE ES SFlow v1/v2 (Python) — SUPERADO POR v3

La versión viva es SFlow v3, un rebuild nativo en Swift: repo daniel-carreon/sflow-next · local ~/Developer/software/sflow-next/. Es la que está instalada en /Applications/SFlow.app (aquí quedó SFlow-v1-backup.app).

Este repo se conserva SOLO como referencia histórica. No lo desarrolles. Si te pidieron trabajar en "SFlow", es casi seguro que quieren sflow-next. v3 comparte el mismo data dir (~/Library/Application Support/SFlow/) y los mismos IDs de modelo — la migración v1→v3 fue cero copia.

What is SFlow?

SFlow is a macOS voice-to-text desktop tool that replaces Wispr Flow ($15/month). It captures audio via global hotkeys, transcribes using Groq Whisper API (~$0.02/hour), and auto-pastes text wherever the cursor is. It includes a floating pill UI overlay, real-time audio visualization, SQLite history, and a web dashboard.

Quick Start (Dev Mode)

# 1. Install system dependency
brew install portaudio

# 2. Create virtual environment
python3 -m venv venv
source venv/bin/activate

# 3. Install Python dependencies
pip install -r requirements.txt

# 4. Set up environment
cp .env.example .env
# Edit .env and add your GROQ_API_KEY (get one at https://console.groq.com/keys)

# 5. Run
python3 main.py

Build Desktop App (.app bundle)

# Recommended: full install dance (build + ditto + kill old proc + relaunch + open Accessibility panel)
bash install.sh

# Or just build the bundle without installing
bash build.sh

install.sh exists because build.sh alone leaves you with a broken paste — see "Critical: ad-hoc rebuild → silent Accessibility revocation" below.

The .app bundle is self-contained (~478MB — INCLUYE el stack MLX: mlx-whisper + parakeet-mlx + librosa/numba/scipy + los Metal .metallib). No Python, no venv, no terminal. On first launch, if no API key exists in ~/Library/Application Support/SFlow/.env, a dialog asks for it. Menu-bar app.

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.
