About flow-next
Flow Next is a workflow plugin that runs inside AI coding agents such as Claude Code, Codex, Cursor, and Droid, turning a change request into specs, implementation, adversarial cross model review, and a pull request with recorded evidence, and it is aimed at individual developers and teams who already generate code with agents but lack a repeatable way to verify the result.
