prd

prd is a skill for Claude Code from rungchan2/frontend-skills. It costs 79 tokens per session (1,241 once invoked), scanned A, original, Apache-2.0.

A guide for creating a Product Requirements Document, or PRD: a written plan that explains what a product should do, who it is for, and how success will be measured. It uses questions, templates, and prioritisation methods to structure the plan.

In plain words
What is it for?
Use it to define a service, identify user problems and target users, describe core features, set priorities, choose metrics, and produce a structured PRD.
Why use it?
It turns an incomplete product idea into a clearer set of goals, users, problems, requirements, and success measures. The interview questions help reveal missing information before writing the document.

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

prd 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.

사용 예시

사용자: "PRD 만들어줘"

Claude: PRD를 작성하겠습니다. 먼저 몇 가지 질문을 드릴게요.

1. 이 서비스를 한 문장으로 설명한다면 뭐라고 하시겠어요?
2. 서비스 도메인은 무엇인가요? (예: 교육, 이커머스, 헬스케어, SaaS)
사용자: "AI 기반 영어 회화 연습 앱이야. 교육 도메인."

Claude: 좋습니다. 교육 도메인의 KPI 템플릿을 참고하여 성공 지표를 제안드릴게요.
이어서 질문드립니다.

1. 해결하려는 핵심 문제 3가지는 무엇인가요?
2. 기존 영어 학습 앱들이 부족한 점은 무엇인가요?

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.
