  • Ralph Wiggum is a technique for software engineering, primarily a Bash loop that leverages AI tools like @sourcegraph/amp.
  • Ralph is designed for greenfield projects and can replace much of the outsourcing work, though it has identifiable and resolvable defects.
  • The technique is deterministic in its approach but operates in an undeterministic world, requiring continual tuning based on LLM behavior observation.
  • Ralph is currently being used to build a new programming language called CURSED, demonstrating AI's capability to work without prior training data.
  • Building with Ralph requires faith in eventual consistency and hands-off coding, trusting the AI to decide the most important tasks per loop.
  • Key principles include one task per loop, minimal context window usage, and spawning subagents for parallel operations while maintaining control over parallelism.
  • Specifications (specs) are crucial and are formed through initial conversations with the AI, ensuring a clear understanding before implementation begins.
  • Backpressure mechanisms like tests, static analyzers, and security scanners are essential to validate AI-generated code and maintain correctness.
  • Documentation and test explanations are vital for future loops, as they provide context that the AI won't retain in subsequent iterations.
  • Ralph can self-improve by updating its own instructions (AGENT.md) and documenting bugs or learnings in fix_plan.md.
  • The technique is not suitable for existing codebases but excels in bootstrapping new projects, potentially displacing many traditional SWE roles for greenfield work.
  • Senior engineering expertise is still required to guide Ralph, debunking the notion that AI can fully replace human engineers.
  • The current prompts for building CURSED emphasize strict adherence to specifications, avoiding placeholder implementations, and maintaining up-to-date plans and documentation.
