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 | $0.00046 | $0.01423 |
| Opus 5 | $0.00023 | $0.00711 |
| Sonnet 5 | $0.00009 | $0.00285 |
| Haiku 4.5 | $0.00005 | $0.00142 |
Grade A, and why
eea-design-system 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.

EEA Design System
Version: 1.0.0 Source: https://github.com/eea/volto-eea-design-system Docs: https://eea.github.io/volto-eea-design-system/
This skill governs how agents apply the EEA Design System when generating, reviewing, or refactoring UI code for EEA web applications.
How to Use This Skill
- Read references/DESIGN.md for the canonical design tokens (colors, typography, spacing, components).
- Use
assets/for official EEA and thematic platform logos. - Follow
EEA-OVERRIDES.mdfor EEA-specific constraints (logo legal rules, proxy compliance, corporate identity manual links). - Reference the Logo component page for implementation details: https://eea.github.io/volto-eea-design-system/docs/webdev/Components/Logo/
Agent Workflow
When a task involves UI, UX, or branding for an EEA project:
- Load this skill.
- Open references/DESIGN.md and apply the relevant tokens.
- If logos are needed, pick the correct variant from
assets/and respect the usage rules inEEA-OVERRIDES.md. - Ensure all color combinations meet WCAG 2.1 AA contrast ratios.
- Prefer sharp edges (
border-radius: 0px) unless the component variant explicitly requires rounding. - Use the 8px grid for spacing and sizing decisions.

Key Constraints
- Never crop, amend, or distort EEA logos.
- Thematic platform logos follow the same legal rules as the main EEA logo.
- All public-facing applications must comply with WCAG 2.1 Level AA.
- Default
border-radiusis0pxacross the system. - Typography: Roboto (fallback Arial), base 16px, bold for headings only.

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.

eea-design-system is a skill published in the GitHub repository eea/eea.agent.skills (2 stars, last pushed 28d ago), licensed MIT. It adds 46 tokens to every session and 1,423 once invoked, about $0.0002 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.
