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 | $0.00110 | $0.00857 |
| Opus 5 | $0.00055 | $0.00428 |
| Sonnet 5 | $0.00022 | $0.00171 |
| Haiku 4.5 | $0.00011 | $0.00086 |
Grade A, and why
audio-plugin-ui-ux 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Audio Plugin UI/UX
Core principle
Audio plugins are real-time, performance-critical, mouse-and-keyboard instruments living inside someone else's host. They are not websites. Defaults imported from web/mobile UX (large hit areas, hover-reveal everything, generous whitespace, animation everywhere) frequently make plugins worse. Reason from first principles for this medium.
When to use
- Designing or modifying a plugin's GUI in any framework
- Laying out knobs, faders, meters, segment displays, chassis
- Choosing a typography / color / skeuomorphism stance
- Reviewing UI work before committing
- Implementing presets, A/B compare, modulation visualisation, DPI scaling
- Establishing or honouring the developer's house style (Hyperfocus DSP / REXIST)
Mandatory workflow
- Read
guidelines.mdin this skill directory before designing or modifying any plugin UI. - Cite specific rules (
P1.3,L2.4,C4.1,H5.2,R7.4) when justifying decisions in commits, PR descriptions, or your responses to the user. - Run the §8 pre-completion checklist in
guidelines.mdbefore claiming UI work is done. - Surface conflicts between
guidelines.mdand the current task to the user before acting. Never silently override.
Hard rules (excerpt — full list in §7 of guidelines.md)
- Never move a user-approved knob row without explicit request.
- Never auto-shrink text to fit — fix the layout instead.
- Never claim UI work is done without running and visually verifying.
- Never mix skeuomorphic and flat controls in the same plugin.
- Never use pure
#FFFFFFas the brand highlight; use bone#F4F1EA. - Never invent or alter plugin names, parameter names, brand marks, or version numbers.
- Never overload a modifier key silently (must be discoverable via tooltip or docs).
- Never use linear frequency axes for spectrum displays — log only.
- Always render values with units, no bare numbers.
- Always provide both double-click reset and Cmd/Ctrl-click reset.
- Always integer-scale baked assets across DPI; don't re-flow at different scales.
- Always group with proximity before bounding boxes.
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.
