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 | $0.00060 | $0.10275 |
| Opus 5 | $0.00030 | $0.05137 |
| Sonnet 5 | $0.00012 | $0.02055 |
| Haiku 4.5 | $0.00006 | $0.01027 |
Grade A, and why
acoustic-design 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 13d 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.

Acoustic Design
Section 1: Acoustic Fundamentals for Architects
Sound is mechanical energy propagated as pressure waves through air, solids, and liquids. Architectural acoustics splits into two complementary domains: sound insulation (preventing unwanted sound transmission between spaces) and room acoustics (controlling how sound behaves within a space). Every building design decision — from structural material to partition detailing to room volume — has acoustic consequences.
1.1 Sound Transmission Modes
Airborne sound originates in the air and strikes a building element (wall, floor, facade), causing it to vibrate and re-radiate sound on the other side. Sources include speech, music, television, traffic noise, and mechanical plant. The transmission follows a source-path-receiver model: sound pressure at the source excites the separating element, energy is transmitted through the element (and around it via flanking paths), and the receiver perceives the residual sound.
Impact / structure-borne sound originates from direct mechanical excitation of a building element — footsteps on a floor, a door slamming, a pipe vibrating against a wall. The impact creates vibrational waves that travel through the structure, often far from the point of origin, and radiate as airborne sound into receiving rooms. Structure-borne sound is particularly difficult to control because rigid structural connections act as efficient transmission paths. Footfall on an upper floor can be clearly audible two storeys below if the structure is continuous concrete without isolation.
Flanking transmission is indirect sound transmission via paths other than the direct separating element. A high-performance party wall is worthless if sound bypasses it through a continuous floor slab, a shared window reveal, a back-to-back electrical socket, or a common ceiling void. In lightweight construction (steel frame, timber frame), flanking paths routinely limit achieved performance to 5–10 dB below the laboratory rating of the separating element.
What ships with it
2 files 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.

acoustic-design is a skill published in the GitHub repository Abhinavbwj/Skills-Architects (285 stars, last pushed 3mo ago), licensed MIT. It adds 60 tokens to every session and 10,275 once invoked, about $0.0003 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 2026-08-30.
