Harness Loop (Ralph Wiggum Technique)

Run Claude Code in an external bash loop for autonomous, iterative development.

The Harness Loop implements the Ralph Wiggum technique for fully autonomous development by running Claude Code in an external bash loop. Each iteration, Claude reads specs, works on tasks, logs progress, and continues until all acceptance criteria are met.

Overview

Key benefits:

• Autonomous execution: Claude works through tasks without manual intervention
• Progress tracking: Acceptance criteria checkboxes track completion
• Iteration logs: Every iteration creates a detailed report
• Graceful completion: Loop stops when "## COMPLETED" marker is added to PLAN.md
