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 | $0.00058 | $0.06695 |
| Opus 5.5 | $0.00023 | $0.02678 |
| Sonnet 5.5 | $0.00012 | $0.01339 |
| Haiku 4.5 | $0.00006 | $0.00670 |
Grade A, and why
atlas-design scanned grade A 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 11d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

Atlas Design — Make a Mendix App Look Designed, Not Bland
Reference files
SKILL.md covers the thesis, the layer architecture, the workflow and the
gotchas. The inventories are next door:
reference/building-blocks.md— what Atlas ships out of the box (layouts, page templates, building blocks, widgets) and the appearance vocabulary: the classes and design properties available on each. Look here before writing custom SCSS — most of what people hand-roll already exists as a class.reference/dark-mode-and-charts.md— a dataviz-grade theme for the Mendix chart widgets, and the optional per-widget overrides that make dark mode look deliberate rather than inverted.
When to Use This Skill
Use this skill when:
- The user asks to make an app "look good / professional / branded / less bland"
- You are about to style a Mendix web app or a group of pages
- You are matching a design mock and want it to reach "designed product" quality
- You are re-branding an existing app to a new identity (palette, type, corners)
This is the taste + workflow layer. It sits on top of the styling mechanics
(theme-styling), the widget syntax (create-page), the composition
primitives (fragments), and the design-handoff pipeline
(migrate-design-prototype). It does not re-teach SCSS compilation or
Class:/DesignProperties: syntax — those skills own that. It adds which
tokens/classes to use, when, and the discover → inspect → use method
built on the Atlas building blocks every Mendix project already ships.
What ships with it
2 files 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.

atlas-design is a skill published in the GitHub repository mendixlabs/mxcli (132 stars, last pushed yesterday), licensed Apache-2.0. It adds 58 tokens to every session and 6,695 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
