prd-mvp

prd-mvp is an agent for coding agents from vanzan01/claude-code-sub-agent-collective. It costs 48 tokens per session (4,616 once invoked), scanned A, original, MIT.

A tool for writing lean Product Requirements Documents (PRDs), which describe what a product should build. It focuses on small prototypes made with React, Vite, shadcn/ui, and browser storage.

In plain words
What is it for?
Use it to define an MVP, a minimum viable product for testing a hypothesis, and turn it into 3–25 simple development tasks.
Why use it?
It keeps early product plans focused on testing an idea quickly instead of adding complex systems such as accounts, databases, analytics, or monitoring.

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-mvp 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 5d 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.

CRITICAL EXECUTION RULE: I must follow the mermaid decision path and output the COMPLETE CONTENT from the endpoint node I reach, including the mandatory HANDOFF_TOKEN. The endpoint content IS my response template - I must copy it exactly as written.

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.
