dev-react-headless

dev-react-headless is a command for Claude Code from daangn/seed-design. It costs 7 tokens per session (362 once invoked), scanned A, original, Apache-2.0.

A command set for implementing React headless components, which provide behavior and state without built-in visual styling. It supports single-part, multipart, and hook-only component patterns.

In plain words
What is it for?
Use it to build style-free React components with controlled or uncontrolled state, data attributes, forwarded refs, and the project's naming conventions.
Why use it?
It gives developers a consistent structure for separating component behavior from presentation. It also specifies how state, refs, and exported components should be connected.

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

dev-react-headless 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 1mo 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

React Headless 개발

seed-component Skill로 스타일 없는 React Headless 컴포넌트를 packages/react-headless/<id>/에 구현한다. 새 컴포넌트는「새 컴포넌트 또는 한 플랫폼이 없는 포팅」분기, 기존 컴포넌트는「기존 컴포넌트의 구현·동작·구조 변경」분기다(references/implementation-workflow.md). 대상 플랫폼은 react로 정하고(references/platform-gate.md), Headless 레이어는 references/implementation-steps.md「Step 1: Headless (선택)」과 packages/react-headless/AGENTS.md를 따른다.

인자

  • $COMPONENT_NAME: 대상 컴포넌트 이름(PascalCase)
  • $PATTERN: 선택. single|multipart|hook-only

필수 결과

  1. Hook은 use<Name>.ts, 컴포넌트는 <Name>.tsx에 둔다. hook-only면 use<Name>.ts만 둔다.
  2. packages/react-headless/AGENTS.md의 규칙(data-* 상태, useControllableState로 제어·비제어 지원, forwardRef)을 지키고, export하는 컴포넌트에 displayName을 둔다.
  3. 루트 AGENTS.md「검증」의 packages/react-headless/*/ 명령(bun headless:test)을 실행하고 결과를 보고한다.
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.
