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 | $0.00057 | $0.01012 |
| Opus 5.5 | $0.00023 | $0.00405 |
| Sonnet 5.5 | $0.00011 | $0.00202 |
| Haiku 4.5 | $0.00006 | $0.00101 |
Grade A, and why
steamdeck-ui-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 yesterday.
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.

Steam Deck UI Design for decky-music
Use this project-specific skill for decky-music UI work.
Project source of truth
Read these before changing UI behavior:
docs/design/ui-rules.md: architecture-level UI constraints plus the shared visual, focus, button, Footer Legend, and host-safety contract.docs/design/ui-qq.md: QQ provider page rules.docs/design/ui-ncm.md: NCM provider page rules.docs/plan/backlog.md: remaining UI work.
Core layout contract
/musicuses top horizontal provider Tabs and full-width content.- QQ pages: 推荐 / 搜索 / 我的音乐 / 智能电台 / 正在播放.
- NCM pages: 发现 / 私人 FM / 搜索 / 我的 / 正在播放.
- SteamOS global chrome is system-owned: search, notifications, Wi-Fi, battery, time, avatar. Do not draw or focus it.
- Put provider logo, top Tabs,
L1/R1hints, and the current-track status badge in the content header row. - Personal asset pages use the Steam library pattern: second-level Tabs with counts plus full-width list/grid content.
- Search pages must survive soft-keyboard resize without overlapping or fixed-bottom controls.
- Do not add persistent sidebars inside
/music. - Footer Legend is system-rendered through
Focusableaction descriptions; never draw a footer bar. - Do not add a fixed bottom MiniPlayer. Use the status badge, queue overlay, and Now Playing pages.
Focus and gamepad contract
Every interactive element must be reachable by gamepad focus.
| Button | decky-music meaning |
|---|---|
| A | Confirm, play, enter detail, submit search, refresh QR. |
| B | Back, close overlay, cancel manual lyric/comment browsing. |
| X | Context menu; NCM lyrics/comment toggle; radio page may override for trash/next. |
| Y | Queue overlay on normal pages; radio pages may override for like/favorite. |
| Start | Global play/pause blind operation. Hide the hint when queue is empty or backend is unavailable. |
| View | Reserved; do not use for required flows. |
| L1/R1 | Top-level provider page switching. |
| L2/R2 | Secondary Tabs or long-list paging. |
| D-Pad / left stick | Focus roaming; lyrics manual scroll; slider micro-adjustment. |
| Steam / QAM | System reserved, never bind. |
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.
