founder-playbook

founder-playbook is a plugin for Claude Code from heyparsadev/claude-idea-validator. Its manifest loads nothing; the 2 skills, 3 commands, 1 agent it bundles cost 548 tokens per session together, scanned A, original, MIT.

An idea-validation assistant for people planning an early-stage startup. It turns an idea into a testable claim, examines its weaknesses, researches the market and competitors, and uses customer interviews or research to assess whether building it is justified.

In plain words
What is it for?
Use it to test startup ideas, plan and summarize customer discovery, investigate competitors, and decide whether to build.
Why use it?
It helps replace guesswork with evidence before time and money are spent on development. It also provides guided or automatic ways to work through the checks.

Security

Grade A, and why

founder-playbook 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.

What it installs

The manifest is a name and a version. 2 skills, 3 commands, 1 agent travel with it, and installing the plugin installs all of them — 548 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
