## Rules to follow
- Keep the MIT license notice with the code you distribute; the CC0 audio needs no credit.
- Never autoplay on page load; call unlock() from a real pointer or keyboard handler.
- Keep visible feedback alongside sound and give users a persistent mute setting.
- Stop loop cues (loading, processing, recording) when their state ends.

## How an agent gets files
- npm install uisfx; the package ships sounds/{pack}/{cue}.mp3 and .ogg files, and a Web Audio player that synthesizes the sounds locally (sign-in: none)
- Formats: mp3, ogg
- Not allowed: Code is MIT: keep the license notice when you distribute it.
- Not allowed: Audio is CC0; the CC0 dedication does not cover files under .generated.
- Not allowed: Start audio only after a user interaction (call unlock() from a pointer or keyboard handler).

## How to connect

AgentGid's catalog is curated: every entry was checked against the maker's official pages (registry, repository, license and pricing pages) on the date shown; a license value shows the quote it stands on wherever AgentGid has one. Usage numbers come from AgentGid's own scan of public repositories set up for AI coding agents. Claims by makers are reported, not tested by AgentGid.
