vibe-prd

vibe-prd is a skill for Claude Code from KhazP/vibe-coding-prompt-template. It costs 20 tokens per session (360 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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 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

Product requirements

Use existing research, the user's request, and Handoff Context to define the product outcome. Do not repeat an interview whose answers are already known. Ask only for unresolved requirements that affect scope or acceptance; make reversible assumptions explicit and continue when the brief is sufficient.

Write a PRD proportional to the product. Cover the target user and problem, the core journey, MVP scope, out-of-scope work, meaningful failure states, constraints, and observable acceptance criteria. Include AI, accounts, payments, analytics, compliance, or automation only when the product needs them.

For a small project, a short document is enough. For a complex one, clarify dependencies and consequential decisions before they block implementation. Avoid fixed feature counts, mandatory personas, or market research that does not change the product decision. Distinguish agreed facts from assumptions.

Use the manifest's configured PRD path or docs/PRD-[AppName]-MVP.md. End with Handoff Context carrying app, known user level, platform, budget, timeline, mode, constraints, decisions, source files, and open questions. Do not present planned acceptance checks as executed evidence. If the user requested the whole workflow, continue into the technical design within that scope.

For a guided interview with unresolved requirements, consult the relevant optional question prompts.

When producing a document for vibeworkflow, include the exact CLI output metadata. This is a parser contract, not an optional prose template.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
