Blueprint

Coding agents guess too much. On ambiguous tasks, they rush to code or invent a plan that sounds right and misses what you actually wanted. Blueprint reads your code, asks grounded questions that matter, and hands any agent a plan worth executing. The hope is that Blueprint catches what you didn't think to think about. The result is a plan your agent can execute in one shot. Free, open source, and available as agent skills or extensions in Cursor, Windsurf, VS Code.
