fundamental-ngx: Skill for Claude Code

.claude/skills/update-docs/SKILL.md

update-docs is a skill for Claude Code from SAP/fundamental-ngx. It costs 17 tokens per session (688 once invoked), scanned A, original, Apache-2.0.

A documentation-checking command that compares examples and descriptions with a component's current public interface. A component is a reusable part of an application.

In plain words
What is it for?
Use it with a component or documentation path to check public inputs, outputs, models, descriptions, and example files.
Why use it?
It finds documentation that is missing, outdated, or inconsistent with the code, reducing confusion for users of the component.

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

update-docs 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 2mo 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 — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Update Documentation: $ARGUMENTS

If $ARGUMENTS is empty, ask the user for a component path or folder before proceeding.

Verify that documentation examples are in sync with the component's current public API. If a path to a component is given, find its corresponding docs. If a docs path is given, find the component it documents.

Phase 1: Map component to docs

Component locations: libs/core/<component>/ or libs/platform/<component>/ Docs locations: libs/docs/core/<component>/ or libs/docs/platform/<component>/

Read:

  • The component .ts file — extract all input(), output(), model(), @Input(), @Output() declarations
  • The docs component (e.g. <component>-docs.component.ts and .html)
  • All example files in the docs examples/ folder

Phase 2: Audit

API coverage

For each public input/output/model on the component:

  • Is it demonstrated in at least one example?
  • Is it mentioned in a <description> block?
  • If it has non-obvious behavior, is there a dedicated section?

Flag inputs/outputs that exist in the component but are not documented anywhere.

Example quality

For each example file:

  • Individual component imports — no deprecated *Module classes
  • @fundamental-styles/common-css utility classes — no inline styles where avoidable
  • Every demonstrated feature is user-observable
  • No unnecessary standalone examples (consolidate where possible)
  • Example code matches current API (no removed/renamed inputs)

Description accuracy

For each <description> block in the docs HTML:

  • Input/output names in <code> tags match the actual component API
  • Described behavior matches the component's implementation
  • No references to removed or renamed APIs

Phase 3: Fix

For each issue found:

  1. Missing documentation — Add the input/output to an existing example's description, or add it to an existing example template if it can be demonstrated inline
  2. Stale references — Update <code> tags and descriptions to match current API
  3. Convention violations — Replace deprecated module imports, replace inline styles with common-css classes

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.
