fundamental-ngx: Skill for Claude Code

.claude/skills/scaffold/SKILL.md

scaffold is a skill for Claude Code from SAP/fundamental-ngx. It costs 26 tokens per session (1,008 once invoked), scanned A, original, Apache-2.0.

A component-scaffolding skill for Angular applications that use fundamental-ngx, a UI component library. It generates starting structures for dialogs, tables, cards, forms, app shells, and responsive grids.

In plain words
What is it for?
Creating a dialog, data table, content card, form, application shell, or responsive layout grid. It can use library usage guides, APIs, and documented examples to shape the result.
Why use it?
It provides the correct component patterns, selectors, inputs, imports, and examples needed to start a working UI component. This reduces mistakes when combining library components.

About the project

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.

Token cost

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.

Security

Grade A, and why

scaffold 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.

How it starts

The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scaffold: $ARGUMENTS

If $ARGUMENTS is empty, ask the user which pattern they want. Supported patterns:

  • dialog — modal dialog (template / component-ref / object-based variants)
  • table — data table (fd-table / fdp-table / ui5-table variants)
  • card — content card with header and body
  • form — form layout with form-items and validation
  • shell — app shell with shellbar and navigation
  • layout-grid — responsive grid layout

Phase 1: Identify Pattern

Parse the pattern name from $ARGUMENTS. If a variant is specified (e.g., dialog component-ref), note it for Phase 3.

Phase 2: Gather Context

Use the @fundamental-ngx/mcp MCP server tools to get accurate, up-to-date information:

  1. Call get_usage_guide with the pattern name to get:

    • Decision tree for choosing variants
    • Composition patterns (correct parent/child nesting)
    • Common pitfalls to avoid
    • Related components
  2. Call get_component_api for the primary component to get:

    • Correct selector (element vs attribute)
    • Available inputs and their types
    • Required imports
  3. Call get_component_examples to get real working examples from the docs app.

If the MCP server is not available, fall back to reading libs/mcp-server/src/data/usage-guides.ts directly.

Phase 3: Choose Variant

If the pattern has multiple variants (e.g., dialog has 3 API surfaces):

  • If the user specified a variant in $ARGUMENTS, use it
  • Otherwise, present the decision tree from get_usage_guide and ask the user to choose

Phase 4: Determine Target Location

Ask the user where to generate the component:

  • Path relative to their project (e.g., src/app/dialogs/confirm-dialog)
  • Component name (e.g., ConfirmDialog)

If the user provides just a name, default to src/app/components/<name>/.

Phase 5: Generate Component

Create a complete Angular component with:

  1. TypeScript file (.component.ts):

    • Correct imports from @fundamental-ngx/core, @fundamental-ngx/platform, or @fundamental-ngx/ui5-webcomponents
    • ChangeDetectionStrategy.OnPush
    • Signal-based state (signal(), computed())
    • input() / output() for component API
    • Proper selector with fd- prefix conventions

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.
