I implemented some of his setup and have been loving it so far.

My current workflow is typically 3-5 Claude Codes in parallel

- Shallow clone, plan mode back and forth until I get the spec down, hand off to subagent to write a plan.md

- Ralph Wiggum Claude using plan.md and skills until PR passes tests, CI/CD, auto-responds to greptile reviews, prepares the PR for me to review

- Back and forth with Claude for any incremental changes or fixes

- Playwright MCP for Claude to view the browser for frontend

I still always comb through the PRs and double check everything including local testing, which is definitely the bottleneck in my dev cycles, but I'll typically have 2-4 PRs lined up ready for me at any moment.
