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 | $0.00074 | $0.10602 |
| Opus 5.5 | $0.00030 | $0.04241 |
| Sonnet 5.5 | $0.00015 | $0.02120 |
| Haiku 4.5 | $0.00007 | $0.01060 |
Grade A, and why
migrate-design-prototype 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 5d 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 — 724 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Find it fast
sed -n '<from>,<to>p' SKILL.md one section rather than reading the file;
./mxcli syntax <topic> answers how do I write this for a fraction of either.

Migrate a Claude Design Prototype into a Mendix App (Theme + Pages)
When to Use This Skill
Use this skill when you are given a Claude Design prototype / design handoff (an HTML/CSS
prototype, a *.dc.html design-console export, a tokens file, a PRD, and/or screenshots) and need to reproduce that look in a Mendix app using mxcli + MDL.
It covers the two halves of the job:
- Build the SCSS theme — turn the prototype's design language (colours, fonts, spacing, component styles) into a Mendix theme in
theme/web/main.scss. - Apply it in pages — attach the theme's classes to widgets with MDL
(
Class:/DynamicClasses:oncreate page/alter page).
Related skills: atlas-design (read first — the Atlas-first taste + workflow layer),
theme-styling (SCSS compilation chain, hot-reload, styling caveats),
create-page (widget syntax), alter-page (in-place widget edits),
bulk-widget-updates (apply a class across many widgets).
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.

migrate-design-prototype is a skill published in the GitHub repository mendixlabs/mxcli (130 stars, last pushed yesterday), licensed Apache-2.0. It adds 74 tokens to every session and 10,602 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-30.
