authoring-examples

Guidance for writing .examples.ts files, which contain reusable HTML examples for components. It defines naming rules, required summaries, and stateless example structure.

In plain words
What is it for?
Use it when creating, editing, or reviewing component examples and their names or summary comments.
Why use it?
It keeps component examples easy to find, understand, and review while avoiding examples that contain their own application state.

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

authoring-examples 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 2d 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.

What it actually says

Authoring Examples (*.examples.ts)

You MUST review @projects/site/src/docs/internal/guidelines/examples.md before making any changes to example files.

When to Use This Skill

  • Creating new *.examples.ts files for components
  • Adding or updating example templates within existing example files
  • Reviewing example naming conventions and structure
  • Writing or updating @summary JSDoc comments for examples

Key Principles

  1. PascalCase Naming: Use PascalCase for example names (for example, Default, StatusFlat, FormSubmit)
  2. Concise Names: Keep example names to 1-3 words maximum, describing what the example shows
  3. Required @summary: Every example must include a @summary JSDoc comment explaining what, why, when, and how
  4. Stateless Templates: Examples should be stateless HTML templates demonstrating UI patterns

Naming Patterns

  • Single words: Default, Status, Size, Color, Disabled
  • Compound names: StatusFlat, StatusIcon, FormSubmit, VerticalTabs
  • Special prefixes: Legacy*, Invalid*, Valid*

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.
