FAQPage SchemaHow to install who-built-this-before-me?▼
Run `npx skills add iagochavarry/who-built-this-before-me --all -g -y` in your terminal to install the skill globally.
How to check if my app idea already exists?▼
Describe your idea in plain language and the skill searches GitHub, npm, Product Hunt, Hacker News, and research papers for existing solutions. It then groups results into direct matches, adjacent tools, partial solutions, and abandoned projects.
What verdicts does the prior art report give?▼
Every report ends with one clear verdict: build it, fork an existing project, contribute upstream, use an existing solution, or investigate why a previous attempt failed. It also names the concrete next step.
Does it work with Claude Code and OpenCode?▼
Yes. The skill follows the standard SKILL.md format and runs in Claude Code, OpenCode, and other compatible coding environments.
Do I need technical skills to validate an idea?▼
No. Just describe what you want to build in plain English, and the skill handles the searching, clustering, and analysis for you.
