"Ralph Wiggum" AI Agent Explained (& How to Use It)
The Startup Ideas Podcast
How to Get Started with the Ralph Repo
Ryan points listeners to the Ralph repo and advises telling the agent to set it up and guide first runs.
We got Ryan Carson on the pod to break down the “Ralph Wiggum” Agent and why it’s suddenly everywhere. He walks me through a simple workflow that lets an autonomous agent build a full product feature while I sleep: start with a PRD, convert it into small user stories with tight acceptance criteria, then run a looped script that ships work in clean iterations. The big idea is you’re not “vibe coding” one giant prompt—you’re giving the agent testable, bite-sized tickets and letting it execute like an engineering team. By the end, Ryan shows how this becomes repeatable (and safer) with a memory layer—agents.md for long-term notes and progress.txt for iteration-to-iteration context.

Key Points
I can’t expect “sleep-shipping” unless I translate the feature into small, testable user stories with clear acceptance criteria.
Ralph works like a Kanban loop: pull one story, implement, commit, mark pass/fail, then grab the next.
The real leverage is the reset: each iteration starts fresh with a clean context window, instead of one giant, messy thread.
agents.md becomes long-term memory across the repo; progress.txt is short-term memory across iterations.
The bottleneck isn’t “coding”—it’s the upfront spec quality: PRD clarity, atomic stories, and verifiable criteria.
