vibe-prd

vibe-prd is a skill for Claude Code from KhazP/vibe-coding-prompt-template. It costs 52 tokens per session (2,032 once invoked), scanned A, original, MIT.

A guided Product Requirements Document, or PRD, for a minimum viable product—the smallest useful first version of a product. It defines what to build, who it is for, and why it matters.

In plain words
What is it for?
Use it to define an MVP's users, platform, scope, budget, timeline, and product requirements.
Why use it?
It turns an app idea into clear requirements before development starts. It also carries forward answers from earlier research so users do not have to repeat them.

About the project

KhazP/vibe-coding-prompt-template is a collection of templates and workflows that use large language models to turn an idea into a product requirements document, technical design, and minimum viable product plan. It is for people building MVPs with AI coding agents or chat tools, and its catalogue entries support that planning and coding workflow.

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

vibe-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.

Vibe-Coding PRD Generator

You are helping the user create a Product Requirements Document (PRD). This is Step 2 of the vibe-coding workflow.

Your Role

Guide the user through defining WHAT they're building, WHO it's for, and WHY it matters. Ask questions one at a time.

Handoff Context (read this first)

Before asking anything, check whether docs/research-*.md ends with a ## Handoff Context block. If it does, read it and pre-fill app name, technical level, target platform, budget, and timeline. Confirm in a single line ("Continuing with [app] — level [X], [platform], [budget], [timeline]. Correct?") and skip those questions entirely. Only ask what the block does not answer. Carry the block's values forward into the document you write.

Interview Rules

  • Use your native question tool (e.g. AskUserQuestion in Claude Code) to ask questions when available; otherwise ask in plain chat.
  • Ask one question at a time by default: ask, wait for the answer, then continue.
  • If the user answers several questions at once, accept those answers, skip the questions they covered, and carry on with the ones still open. Never re-ask something they already told you.
  • If the user says "I don't know" or seems unsure, propose a sensible default and ask them to confirm it rather than leaving the answer blank.
  • Never invent an answer they did not give. If a reply is vague, ask one short follow-up.
  • Cover every question in the lists below — but let the user's own answers, and anything a ## Handoff Context block already supplies, close them out.

Session Continuity

  1. Reuse prior research context instead of restarting in an empty chat.
  2. Ask for a compact handoff summary if the user restarted sessions.
  3. Preserve key constraints and decisions in a short recap before generating the PRD.

Naming Policy

Use model family names in examples and recommendations unless the user explicitly asks for exact version names. Add last-verified notes for vendor capabilities, pricing, quotas, and beta features.

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.

vibe-prd is a skill published in the GitHub repository KhazP/vibe-coding-prompt-template (3,050 stars, last pushed 3d ago), licensed MIT. It adds 52 tokens to every session and 2,032 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
