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 | $0.00231 | $0.02347 |
| Opus 5 | $0.00115 | $0.01174 |
| Sonnet 5 | $0.00046 | $0.00469 |
| Haiku 4.5 | $0.00023 | $0.00235 |
Grade A, and why
embedded-ui-svg-doc-from-source 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 10d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Embedded-UI SVG Doc from Source
When the embedded device already draws its UI with literal pixel coordinates in code, translate those coordinates 1:1 into SVG <rect>/<text>/<line> elements. Do not rebuild the layout semantically with CSS — that path is lossy and produces 4-8 iterations of "wrong pill width", "wrong text offset", "wrong padding".
The maxim is the CAD principle applied to docs: measure, don't estimate. The source code IS the measurement.
When to use
- Writing a printable end-user manual (PDF/HTML) for an embedded touchscreen device where the screen layouts must appear in the manual
- Producing design-review mockups when the device is not at hand
- Updating existing UI docs after a screen refactor in source — diff the draw calls, diff the SVG
- Onboarding a gifted-recipient with no software background (typical use case: a small embedded controller given to a hobbyist)
When NOT to use
- Web-frontend mockups → use
frontend-design,marketing, orui-ux-pro-max - Real photos of the device screen suffice → just photograph and embed; this skill is for the case where the hardware is not available or photos are awkward (glare, font rendering, parallax)
- LVGL with style objects only and no literal coordinates → harder; this skill assumes literal
x, y, w, hin the source - CAD or mechanical drawings →

The core translation pattern
| Source-Code Call (LovyanGFX / generic) | SVG Element |
|---|---|
gfx.fillRect(x, y, w, h, color) |
<rect x="X" y="Y" width="W" height="H" fill="#color"/> |
gfx.drawRect(x, y, w, h, color) |
<rect ... fill="none" stroke="#color"/> |
gfx.fillRoundRect(x, y, w, h, r, color) |
<rect ... rx="R"/> |
gfx.drawString("text", x, y) |
<text x="X" y="Y" font-family="..." font-size="...">text</text> |
gfx.drawLine(x1, y1, x2, y2, color) |
<line x1="X1" y1="Y1" x2="X2" y2="Y2" stroke="#color"/> |
gfx.fillCircle(cx, cy, r, color) |
<circle cx="CX" cy="CY" r="R" fill="#color"/> |
gfx.drawTriangle(x1,y1,x2,y2,x3,y3,color) |
<polygon points="X1,Y1 X2,Y2 X3,Y3"/> |
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.

embedded-ui-svg-doc-from-source is a skill published in the GitHub repository Ed3Design/ed3design-engineering-bundles (2 stars, last pushed 1mo ago), licensed MIT. It adds 231 tokens to every session and 2,347 once invoked, about $0.0012 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 2026-08-31.
