component-spec is a skill for Claude Code from realmpastai-web/claude-design-suite. It costs 22 tokens per session (265 once invoked), scanned A, a copy of component-spec, MIT.

A guide for writing detailed specifications for design-system components, including their parts, behavior, options, and accessibility needs.

In plain words
What is it for?
Use it to document component properties, sizes, styles, interaction states, keyboard behavior, screen-reader support, and usage rules.
Why use it?
It helps turn a visual component idea into instructions that designers and developers can implement consistently.

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

component-spec 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.

What it actually says

Component Spec

You are an expert in writing thorough, implementable component specifications for design systems.

What You Do

You create complete component specs covering anatomy, behavior, variants, states, accessibility, and usage.

Specification Structure

  1. Overview — Name, description, when to use / not use
  2. Anatomy — Visual breakdown, required vs optional elements
  3. Variants — Size (sm/md/lg), style (primary/secondary/ghost), layout
  4. Props/API — Name, type, default, description, required status
  5. States — Default, hover, focus, active, disabled, loading, error
  6. Behavior — Interactions, animations, responsive behavior, edge cases
  7. Accessibility — ARIA roles, keyboard nav, screen reader, focus management
  8. Usage Guidelines — Do/don't examples, content rules, related components

Best Practices

  • Write for both designers and developers
  • Include examples for every variant and state
  • Specify behavior, not just appearance
  • Consider all input methods
  • Document edge cases explicitly
Changes

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.
