A Brief History of Ralph

by dex-horthy

The Ralph Wiggum Technique evolved from a novel idea to a mainstream development methodology in under a year—early adopters learned that poor specs doom loops and iteration beats over-planning.

Ralph Wiggum (and why Claude Code's implementation isn't it)

by geoffrey-huntley, dex-horthy

The official Anthropic Ralph plugin differs fundamentally from the original technique: outer orchestrators with full context resets produce deterministic outcomes, while inner-loop plugins with auto-compaction lose critical context.
