create-component

create-component is a command for coding agents from Owl-Listener/designer-skills. It costs 21 tokens per session (221 once invoked), scanned A, original, MIT.

A command that creates a complete specification for a user-interface component, including its inputs, states, variations, accessibility behaviour, and documentation.

In plain words
What is it for?
Use it when designing a new component and documenting its structure, API, variants, states, accessibility requirements, naming, and design-token usage.
Why use it?
It provides one consistent checklist for defining a component before it is built. This helps prevent missing keyboard behaviour, unclear states, or undocumented usage.

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

create-component 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 6d 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

/create-component

Generate a comprehensive component specification.

Steps

  1. Research — Understand purpose and common implementations.
  2. Anatomy — Break down parts using component-spec skill.
  3. Variants — Define size, style, layout variants.
  4. States — Map interactive states using component-spec skill.
  5. Tokens — Identify consumed tokens using design-token skill.
  6. Accessibility — Specify ARIA, keyboard, screen reader using accessibility-audit skill.
  7. Naming — Follow conventions using naming-convention skill.
  8. Documentation — Structure using documentation-template skill.

Output

Complete spec: overview, anatomy, props/API, variants, states, accessibility, usage guidelines, tokens. Consider following up with /audit-system.

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.
