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.

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 | $0.00026 | $0.02779 |
| Opus 5 | $0.00013 | $0.01389 |
| Sonnet 5 | $0.00005 | $0.00556 |
| Haiku 4.5 | $0.00003 | $0.00278 |
Grade A, and why
component-guidance-navigation 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 9d 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.

Navigation and wayfinding components.
When to Use This Skill
Use this skill when:
- The user asks "Should I use [component] for [use case]?"
- The user needs to choose between similar components
- The user asks about component best practices
- The user wants to know when NOT to use a component
This skill covers: Breadcrumb, Icon Tab Bar, Link, Menu, Pagination, Shellbar, Toolbar, Vertical Navigation
Breadcrumb
Description: A breadcrumb (or breadcrumb trail) is a type of secondary navigation that indicates the position of a page in its application hierarchy. It is typically used for drilldown scenarios where users navigate through related object pages, tables, and charts.
When to use:
- Show secondary navigation on the object page
- Show navigation in a table
- Show navigation in charts
- Support a user flow that involves drilling down through multiple related object pages (Parent → Child 1 → Child 2 → Child 3)
- Display the current location in a hierarchy
- Enable navigation back to parent pages
When to avoid:
- ❌ Your hierarchy contains only one level
- ❌ Linking to other floorplans, such as overview pages or list reports
- ❌ Navigating across applications to unrelated object pages
- ❌ Linking to standalone object pages, such as fact sheets → Use global navigation instead
Best practices:
- ✅ Use separator modifiers:
fd-breadcrumb--backslashorfd-breadcrumb--double-greater-than - ✅ Current item can be displayed as non-interactive (without separator) or as a regular link
- ✅ Use overflow breadcrumb with
fd-popoverfor long paths with insufficient horizontal space - ✅ Make each breadcrumb item clickable to navigate to that level
- ✅ Display breadcrumbs horizontally in a single line
- ✅ Use overflow dropdown menu when there are too many levels
- ⚠️ Implement responsive behavior to collapse into dropdown on small screens
- ⚠️ Keep breadcrumb hierarchy meaningful and accurate
Icon Tab Bar
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.

component-guidance-navigation is a skill published in the GitHub repository SAP/fundamental-styles (232 stars, last pushed 5d ago), licensed Apache-2.0. It adds 26 tokens to every session and 2,779 once invoked, about $0.0001 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 2026-08-30.
