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 | $0.00045 | $0.01634 |
| Opus 5 | $0.00023 | $0.00817 |
| Sonnet 5 | $0.00009 | $0.00327 |
| Haiku 4.5 | $0.00005 | $0.00163 |
Grade A, and why
audio-router 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 12d 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.

Audio Router
Routes to 3 specialized skills based on audio requirements.
Routing Protocol
- Classify — Identify audio task from user request
- Match — Apply signal matching rules below
- Combine — Audio-visual projects need 2-3 skills together
- Load — Read matched SKILL.md files before implementation
Quick Route
Tier 1: Core Skills
| Need | Skill | Signals |
|---|---|---|
| Playing audio, music, SFX | audio-playback |
play, load, music, sound, mp3, transport, player, loop |
| Extracting audio data | audio-analysis |
FFT, frequency, spectrum, amplitude, waveform, beat detection |
| Visual-audio connection | audio-reactive |
visualizer, reactive, respond to audio, sync, pulse, beat-driven |
Signal Matching
Primary Signals
audio-playback:
- "play audio", "load music", "sound effect"
- "Tone.js", "Player", "transport"
- "loop", "crossfade", "volume"
- "schedule", "timing", "sync to beat"
- "background music", "ambient sound"
audio-analysis:
- "FFT", "frequency", "spectrum"
- "beat detection", "amplitude"
- "waveform", "audio data"
- "frequency bands", "bass", "treble"
- "analyze", "extract", "measure"
audio-reactive:
- "visualizer", "audio reactive"
- "respond to music", "sync visuals"
- "pulse on beat", "frequency to color"
- "music driven", "audio visualization"
- "bloom on bass", "particles on beat"
Confidence Scoring
- High (3+ signals) — Route directly to matched skill
- Medium (1-2 signals) — Route with supporting skills
- Low (0 signals) — Start with
audio-playback
Common Combinations
Simple Audio Player (1 skill)
audio-playback → Load and play audio files
Audio Visualizer (3 skills)
audio-playback → Load and control audio
audio-analysis → Extract frequency/beat data
audio-reactive → Map data to visual properties
Background Music (1-2 skills)
audio-playback → Looping, crossfade, volume
audio-analysis → Optional: beat sync features
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 12d ago First seen · 230 lines · 45 tokens per session scan A 2560d9752a84
audio-router is a skill published in the GitHub repository Bbeierle12/Skill-MCP-Claude (8 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 1,634 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
