SimpMusic is a free and open-source music app for Android and desktop that uses YouTube Music and YouTube as its music backend. It is for people who want to browse, stream, organize, and listen to music with features such as lyrics, equalization, playlists, analytics, caching, and offline playback. The catalogue entries are skills, an instruction, and an agent associated with the app's development.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00207 | $0.02313 |
| Opus 5 | $0.00103 | $0.01156 |
| Sonnet 5 | $0.00041 | $0.00463 |
| Haiku 4.5 | $0.00021 | $0.00231 |
Grade B, and why
ui-ux-pro-max scanned grade B 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 6d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

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.

ui-ux-pro-max is a skill published in the GitHub repository maxrave-dev/SimpMusic (10,953 stars, last pushed yesterday), licensed GPL-3.0. It adds 207 tokens to every session and 2,313 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
