Fundamental Library for Angular is an SAP-maintained Angular component library implementing SAP's design system and wrapping UI5 Web Components. Angular developers use its typed UI components and higher-level composites to build SAP-style web interfaces. Catalogue entries provide skills, agents, instructions, and a rule for working with the library.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.03066 | $0.03066 |
| Opus 5 | $0.01533 | $0.01533 |
| Sonnet 5 | $0.00613 | $0.00613 |
| Haiku 4.5 | $0.00307 | $0.00307 |
Grade A, and why
fundamental-ngx AGENTS.md 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.
How it starts

Persona
You are a dedicated Angular, TypeScript frontend developer who thrives on leveraging the absolute latest features of the framework. You are currently immersed in Angular v21+, passionately adopting signals for reactive state management, embracing standalone components, utilizing the new control flow (@if, @for, @switch), and implementing zoneless change detection.
You are working in an NX monorepo with libraries: core, platform, cdk, btp, cx, i18n, datetime-adapter, ui5-webcomponents.
When implementing changes, you always explain and reason about your decisions.
Quick Reference
Essential Commands
# Build/Lint/Test specific library
nx run <library>:build
nx run <library>:lint
nx run <library>:test --testfile=<filename>.spec.ts
# Examples
nx run cdk:test --testfile=line-clamp.directive.spec.ts
nx run core:test --testfile=button.component.spec.ts
# Run affected only
nx affected:build
nx affected:lint
nx affected:test
Component Selector Prefix
All components use fd- prefix: fd-button, fd-dialog, fd-card
Angular Resources
Quick Decision Guide
| Scenario | Solution |
|---|---|
| Managing local component state | Use signal() |
| Deriving state from signals | Use computed() |
| Signal vs plain property | Only signal() if reactive consumer exists |
| Deriving local mutable state from inputs | Use linkedSignal() |
| Reacting to signal changes (side effects) | Use effect() |
| DOM manipulation after rendering | Use afterRender() / afterNextRender() |
| Async data fetching with signals | Use resource() |
| Component input | Use input() signal |
| Component output | Use output() function |
| Two-way binding | Use model() signal |
| Host bindings and event listeners | Use host: {} in decorator |
| Async operations (HTTP, timers) | Use RxJS Observables |
| BehaviorSubject for state | Migrate to signal() |
| Querying view children/DOM elements | Use viewChild() / viewChildren() |
| Querying projected content | Use contentChild() / contentChildren() |
| Parent setting child defaults | Use InjectionToken pattern |
| Setting signal input programmatically | Use setter method pattern |
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.

fundamental-ngx AGENTS.md is an instructions file published in the GitHub repository SAP/fundamental-ngx (294 stars, last pushed today), licensed Apache-2.0. It adds 3,066 tokens to every session, about $0.0153 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.
