Ralph Loop Agent Orchestrator

The playbook for making coding agents actually finish the job. Many short sprints, not one marathon — fresh context each time prevents context drift. Includes: PRD-driven task specs, mandatory tmux with stable sockets and completion hooks, stall detection (same output 2+ checks = kill and restart), two-model split (planning with Opus, execution with Codex), and the verify-before-declaring-failure checklist (git log + git diff + process logs). Built from hundreds of hours of real agent orchestration.

Includes: SKILL.md, PRD template, tmux patterns, stall detection script, verification checklist.
