Add Ralph loop tooling for autonomous spec implementation#9
Merged
Conversation
Enables running approved spec plans autonomously with a fresh Claude context per task (the original Ralph technique), instead of one long session that degrades as context fills. ralph.ps1 drives three phases around a spec index: /create-prd derives a gated task list from the spec plan, the loop implements one task per iteration with headless or Unity MCP verification, and /complete-prd hands off via the existing /commit and /pr skills. Per-phase cost metrics are logged to support comparing Ralph against single-session implementation. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
