Fundamental Library Styles is a framework-independent CSS component library for creating SAP web interfaces with reusable styles and components. Developers can use it with Angular, React, Vue, or plain HTML to build consistent SAP applications and apply supported visual themes.
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.

SkillSpector: 4 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00028 | $0.03211 |
| Opus 5.5 | $0.00011 | $0.01284 |
| Sonnet 5.5 | $0.00006 | $0.00642 |
| Haiku 4.5 | $0.00003 | $0.00321 |
Grade A, and why
content-density 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 1mo 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.

Content Density in Fundamental Styles
SAP Fiori provides content density modes that allow you to render components at different sizes to optimize for different devices and use cases.
When to Use This Skill
Use this skill when you need to:
- Choose between cozy, compact, or condensed modes
- Apply content density to your application or specific sections
- Understand when to use touch-friendly vs information-dense layouts
- Optimize UI for different device types (touch vs mouse/keyboard)
Content Density Modes
Cozy Mode (Default)
Description: Cozy mode displays components with dimensions large enough for fingertip interaction. The default touch area is 2.75 rem (44 px).
When to use:
- Touch screen devices (mobile, tablets)
- Products that benefit from spacious layouts
- Apps where user comfort is prioritized over information density
- Default mode when no density class is specified
Metrics:
- Touch area: 2.75 rem (44 px)
- Larger spacing between components
- Optimized for finger interaction
Best practices:
- ✅ Use for entire app on touch devices
- ✅ Set as default for mobile-first applications
- ✅ Use when users need larger tap targets
Compact Mode
Description: Compact mode reduces component dimensions to display more information on screen. The touch area is reduced to 2 rem (32 px). Font sizes remain the same, but components and spacing are smaller.
When to use:
- Devices operated with mouse and keyboard
- Desktop applications
- Products requiring high information density
- Data-heavy interfaces (tables, forms, dashboards)
Metrics:
- Touch area: 2 rem (32 px)
- Smaller margins and padding
- Same font size as cozy mode
- Visually more compact appearance
Best practices:
- ✅ Use for entire app on desktop devices
- ✅ Set as default for products requiring high information density
- ✅ Use for data tables and complex forms
- ✅ Apply at application level, not per component
Condensed Mode
Description: Condensed mode further reduces component dimensions and letter spacing for maximum information density. Primarily used on small screens or very information-dense layouts.
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.
- 1mo ago First seen · 508 lines · 28 tokens per session scan A 47a3bf8ac20f
content-density is a skill published in the GitHub repository SAP/fundamental-styles (237 stars, last pushed yesterday), licensed Apache-2.0. It adds 28 tokens to every session and 3,211 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 2026-08-30.
