Writes a product requirements document against a format, or fills out an existing one, in markdown files by default or in a repo or Notion by config. Triggers - "/pm:prd", "write the PRD", "draft the requirements", "PRD 작성", "PRD 만들어줘", "기능 항목 추가", "PRD 보강", "사용자 그룹 추가".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# prd — writing and extending a format-based requirements document
**Part of a plugin.** The scripts this skill runs ship beside it under `${CLAUDE_PLUGIN_ROOT}`. If that path does not resolve, this file was installed on its own — stop and say the plugin itself is needed (`claude plugin install pm@byjunyoung`), rather than improvising what the scripts do.
When a PRD is being written or worked on, the material is gathered and analysed first, and the result becomes a **recommended answer**. The user adopts it with a single "go", or writes a different answer instead. Every question carries the option judged most fitting, marked (recommended).
A PRD keeps growing. Keep the body thin and push the detail out into the entry list, the tickets, and the design file.
**And it is read by people who cannot open the code.** Whoever designs the screens, settles the scope, runs the product once it ships. A requirement is worth what the sentence carrying it is worth to them — 2.4 is the rule, and the second check in 3 is the gate.

How to install
mdr add byjunyoung/claude-product-skills/prd@sha256:c4526eecbe98c83cThe line at the top of this page pins the label git:20261027.50aae49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
