Short answers
A structured build spec: what the app does, the open-source repos it uses and how data flows between them, the steps in order, paid add-ons and licence notes, and a source for every fact. The copy button gives you a short prompt that points your agent at the full blueprint.
Blueprints are tested with Claude Code. Codex, Cursor, Grok and other agents can read the same Markdown blueprint, but we have not verified builds with them yet, so expect to guide them more.
It helps, but several builds are marked Beginner. Your agent does the setup and is told to ask before spending money or using your accounts. You still review what it installs and any keys or settings it asks for.
Usually, but it depends on the licence. Each project shows its licence and whether commercial use is allowed. Projects you can read but not freely reuse are marked source-available, not open source.
Yes. Connect it to https://repoquarry.dev/mcp, or point any agent that browses at https://repoquarry.dev/llms.txt. Every page also has a Markdown copy.
