snarktank/ralph: Autonomous PRD-to-Completion Agent Loop Reaches 15.6K Stars — Runs Amp or Claude Code Until All Requirements Met
GitHub·medium signal
Ralph implements Geoffrey Huntley's autonomous agent loop pattern: give it a PRD, and it iteratively runs AI coding tools (Amp CLI or Claude Code) with fresh context per iteration until every requirement is checked off. Uses git history, progress tracking files, and JSON task lists for persistent memory across iterations. Includes quality checks (typecheck, tests) and browser verification for frontend work.
