Ralph Wiggum Loop - PRD-Driven Autonomous AI Coding Workflow
About Ralph (Ralph Wiggum loop)
A terminal-first agent loop that repeatedly runs an AI coding agent until PRD items are done, persisting state via git and lightweight artifacts.
Key Capabilities
PRD-driven loop: keeps running until checklist items are completed
Fresh agent context each iteration (reduces drift across long runs)
Git-based memory + artifacts (e.g. progress + PRD state)
Terminal-first workflow for devs comfortable with git and diffs
Scriptable for unattended, long-running tasks
Extensible via Claude Code plugin implementations
Standout Features
Loop until done
Runs repeated agent iterations until PRD items are completed.
Git-based memory
Persists progress via git history plus lightweight artifacts for state.
PRD-first workflow
Keeps work anchored to a checklist so long runs stay structured.

EVERY TOOL VIBE-CODERS SHOULD KNOW ABOUT: @claudeai for coding + debugging, @cursor_ai as AI code editor, @Replit for cloud coding + deployment.
Claude for coding ($20/mo), Supabase for backend (Free), Vercel for deploying (Free), Stripe for payments. The full vibe coder stack for under $35/mo.
The entire AI coding industry just got exposed. Someone leaked the system architecture of every major tool, 30,000+ lines of hidden instructions.
