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 | $0.10789 | $0.10789 |
| Opus 5.5 | $0.04316 | $0.04316 |
| Sonnet 5.5 | $0.02158 | $0.02158 |
| Haiku 4.5 | $0.01079 | $0.01079 |
Grade A, and why
paper-cranes CLAUDE.md scanned grade A with 1 finding 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 5d 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.

Paper Cranes / Beadfamous - Music Visualization System
Project Overview
A real-time browser-based music visualization system that:
- Performs advanced audio analysis from microphone input
- Drives GPU-accelerated WebGL visualizations
- Controls LED lights through screen scraping
- Works on mobile devices
- Supports physical bead bracelets that link to specific visualizations
Architecture
Audio Processing Pipeline
Microphone → MediaStream → AudioContext → WindowNode (Hanning) → FFT Analyzer → Workers → Features → Shader
Key Components
1. AudioProcessor (src/audio/AudioProcessor.js)
- FFT Size: 4096 (optimized from 32768 for ~85ms latency)
- Smoothing: 0.15 exponential smoothing factor
- Analyzer Smoothing: 0.2 time constant
- Uses Web Workers for parallel feature extraction
- Extracts 15 audio features from hypnosound library
2. WorkerRPC (src/audio/WorkerRPC.js)
- Manages worker communication with 30ms timeout
- Handles feature calculation in parallel
- Returns smoothed default values on timeout
3. Visualizer (src/Visualizer.js)
- WebGL2 context with frame buffer ping-ponging
- Passes audio features as uniforms to shaders
- Supports previous frame access for feedback effects
- Dynamic resolution scaling for performance
Audio Features Available
Each feature has 11 statistical variations:
- Current value (e.g.,
bass) - Normalized (0-1 range, e.g.,
bassNormalized) - Mean (historical average)
- Median (historical median)
- Min/Max (historical range)
- StandardDeviation (variability)
- ZScore (-1 to 1, for detecting anomalies/drops)
- Slope (linear regression slope over history window — is the feature rising or falling?)
- Intercept (predicted value at start of history window)
- RSquared (0-1, how well a linear trend fits — 1.0 = perfect trend, 0 = no trend)
Core Features:
- SpectralCentroid, SpectralFlux, SpectralSpread, SpectralRolloff
- SpectralRoughness, SpectralKurtosis, SpectralEntropy, SpectralCrest
- SpectralSkew, PitchClass
- Bass, Mids, Treble
- Energy
- Beat detection
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.

paper-cranes CLAUDE.md is an instructions file published in the GitHub repository loqwai/paper-cranes (7 stars, last pushed 3d ago), licensed BSD-3-Clause. It adds 10,789 tokens to every session, about $0.0432 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-02.
