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 | $0.00030 | $0.00458 |
| Opus 5.5 | $0.00012 | $0.00183 |
| Sonnet 5.5 | $0.00006 | $0.00092 |
| Haiku 4.5 | $0.00003 | $0.00046 |
Grade A, and why
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 2mo 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.
What it actually says
Role
Use Aura as the default UI system for customer-facing product work. Prefer decision-level guidance over exhaustive rules:
- choose the right primitive first,
- apply semantic tokens (no raw values),
- keep layouts and UX states consistent,
- write concise, action-oriented copy.
Note: Make sure the project is using the latest version of Aura (
@cognite/aura) to access the most up-to-date guidance and components.
Everything you need to know is:
- In the node_modeules/@cognite/aura folder
- Aura Design Guidlines can be found at:
./node_modules/@cognite/aura/DESIGN.md - At the storybook https://master--695bb4b1b8041ae09768950a.chromatic.com/?path=/docs/primitives
- On the docs site https://docs.cognite.com/aura-design-system/primitives
Consult this skill whenever you are:
- Creating or migrating interactive UI, forms, tables, navigation, or data display
- Writing or modifying styles, colors, spacing, or typography
- Choosing components, tokens, or layout patterns
- Creating or restructuring pages and responsive layouts
- Writing or editing any user-facing text
- Building forms, handling API responses, async actions, confirmations, or dynamic content
- Implementing accessibility (keyboard, focus, headings, ARIA, alt text)
- Applying Aura correctly in a Flows or React app
Operating principles
- Use Aura primitives before custom UI.
- Follow foundations through semantic tokens and Aura defaults; do not hardcode raw values.
- If a primitive almost fits, do not override visuals to force it; check variants/props first, then document the gap.
- Keep behavior predictable and accessible: keyboard support, visible focus, and clear feedback for loading/success/error.
- Use publicly reachable links — Aura design system docs, Storybook, and Figma.
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.

design is a skill published in the GitHub repository cognitedata/builder-skills (6 stars, last pushed yesterday), licensed Apache-2.0. It adds 30 tokens to every session and 458 once invoked, about $0.0001 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 2026-08-31.
