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.

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 | $0.00150 | $0.02087 |
| Opus 5.5 | $0.00060 | $0.00835 |
| Sonnet 5.5 | $0.00030 | $0.00417 |
| Haiku 4.5 | $0.00015 | $0.00209 |
Grade A, and why
material-event-listening 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.

material-event-listening
Purpose
material-event-listening is the ear for sound as matter, vibration, duration, process, and event. It corrects the tendency to treat sound only as source, signal, object, meaning, or style.
This mode listens for what unfolds, resonates, propagates, decays, accumulates, and acts through bodies, rooms, devices, materials, and time.
When To Use
Use this skill for:
- drones, noise, feedback, resonance, hum, rumble, and sustained vibration
- microsound, grains, clicks, bursts, discontinuities, and event density
- sound sculptures, installations, loudspeakers, instruments, physical interfaces, and material sound art
- sub-bass, ultrasound, infrasound, unsound, tactile vibration, and pressure
- weather, engines, machines, infrastructure, geological or architectural sound
- questions about duration, process, flux, emergence, decay, and material agency
- cases where acoulogical object listening feels too static or source-centered
- sonic ontology or methodology questions about object versus event
Core Question
What material event is unfolding, and what does it do across bodies, spaces, devices, and time?
Conceptual Refinements
- Sound can be approached as event rather than object: something that unfolds, persists, decays, and recurs instead of something that simply is.
- Distinguish extensive traits (frequency, amplitude, duration, position) from intensive traits (density, force, grain, pressure); only the first are measurable, and the second must be marked as interpretation.
- Vibration is materially real but epistemically demanding: infrasound, ultrasound, and tactile vibration require measurement or playback context before any bodily-effect claim.
- Material supports are part of the sound: loudspeakers, rooms, surfaces, instruments, bodies, air, and water are agents in the event, not passive containers.
- Sonic materialism is a productive corrective to meaning-first listening, but it must not become a new mysticism; ontology never substitutes for evidence.

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.

material-event-listening is a skill published in the GitHub repository sonicfieldlabs/akouo (10 stars, last pushed 2d ago), licensed MIT. It adds 150 tokens to every session and 2,087 once invoked, about $0.0006 per session on Opus 5.5. 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.
