Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00094 | $0.03008 |
| Opus 5 | $0.00047 | $0.01504 |
| Sonnet 5 | $0.00019 | $0.00602 |
| Haiku 4.5 | $0.00009 | $0.00301 |
Grade A, and why
win31-audio-design 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 9d 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.

Win31 Audio Design: Satisfying Retro Sound Vocabulary
Expert in creating authentic Windows 3.1 era sound experiences for modern web and mobile applications. Focuses on CC-licensed alternatives to the classic sound vocabulary while capturing the satisfying, lo-fi essence of early 90s computing.
When to Use
Use for:
- Win31-themed web applications needing audio feedback
- Retro game interfaces with 90s desktop sounds
- Mobile apps wanting satisfying micro-interaction sounds
- Converting modern flat sounds to vintage 8-bit aesthetic
- Creating sound palettes that evoke early Windows nostalgia
Do NOT use for:
- Modern flat/material sound design → sound-engineer
- Voice synthesis → voice-audio-engineer
- Music composition → DAW tools
- Film sound design → Linear audio workflows
Windows 3.1 Sound Vocabulary
The Original Sounds (Copyrighted - DO NOT USE)
| File | Character | Duration | Function |
|---|---|---|---|
| CHIMES.WAV | Ethereal bells | ~1.5s | System notifications |
| CHORD.WAV | Major chord resolve | ~1.2s | Task completion |
| DING.WAV | Single bell strike | ~0.5s | Attention/alert |
| TADA.WAV | Triumphant fanfare | ~2s | Startup/major success |
| RINGIN.WAV | Rising tone | ~0.3s | Modal open |
| RINGOUT.WAV | Falling tone | ~0.2s | Modal close |

Sound Characteristics (What Made Them Satisfying)
| Quality | Win31 Sound Profile |
|---|---|
| Sample Rate | 11kHz-22kHz (lo-fi charm) |
| Bit Depth | 8-bit (quantization warmth) |
| Frequency Range | 400Hz-4kHz (no sub-bass, gentle highs) |
| Envelope | Fast attack, medium decay, no sustain |
| Reverb | Dry or short room (no cathedral halls) |
| Character | Bright, plasticky, cheerful |
The Win31 "Ding" Formula
┌─────────────────────────────────────────────────────┐
│ Attack: 5-10ms │ Pure sine starts BRIGHT │
│ Peak: ~880Hz (A5) │ Classic 8-bit "bleep" │
│ Decay: 200-400ms │ Natural damping feel │
│ Overtones: 2nd+3rd│ Bell-like shimmer │
│ Processing: 8-bit │ Adds warmth via quantization │
└─────────────────────────────────────────────────────┘
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.

win31-audio-design is a skill published in the GitHub repository curiositech/some_claude_skills (221 stars, last pushed 6d ago), licensed MIT. It adds 94 tokens to every session and 3,008 once invoked, about $0.0005 per session on Opus 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 2026-09-03.
