Ralph Loop Autonomous iteration loop for Claude Code with dual-mode support. Named after the Ralph Wiggum technique popularized in the Claude Code community (Dec 2025 - Feb 2026). Purpose Enable Claude Code to work autonomously on well-defined tasks until genuine completion, without manual re-prompting. The skill provides: 1. Dual-mode architecture — Standalone mode (Stop hook) or multi-agent mode (router-managed iteration) 2. RALPH ACTIVE env var guard — Stop hook only activates when is set, preventing host/router trapping 3. State persistence — JSON state file tracks iteration count, timest…
