Hey all! I wanted to share a kind of new development process I’ve been using lately — I call it "Moonwalk."

Basically it's:

  • Check out a spike branch (git checkout -b reconciliation/spike/mt940)
  • Vibe code fast (and with vim and vigour!) until it feels just right
  • Generate a spec based on the final version
  • Switch back to main (git checkout main)
  • Check out only the spec (git checkout reconciliation/spike/mt940 -- /job-stories) <- This is the moonwalk!
  • Let the "professional" agents and sub-agents write production-grade code based on the spec

It's so effective because I can leverage Claude Code for both: Quickly build a working vibe-heavy prototype spec AND write production-grade code with agentic/sub-agentic quality.

For the vibe code part, the standard Claude Code top-level agent is more than sufficient. It's great, no need for time-costly delegation to sub-agents here.

For the production-grade part, since we're an XP shop with a pretty solid TDD process, sub agents make total sense. We turned our existing process and skills into a bunch of sub-agents that work smoothly together:

We've got...

  • green-minimal-implementer(.)md
  • code-quality-reviewer(.)md
  • code-refactorer(.)md
  • db-migration-specialist(.)md
  • dependency-manager(.)md
  • frontend-design-specialist(.)md
  • locale-translation-specialist(.)md
  • red-test-writer(.)md

So, yeah, that's what I wanted to share with you. Try it out and let me know how I can help :)

Cheers!

PS: For better or worse, this post is 100% written by hand
PPS: My friend Alex Fedorov reminded me that this is pretty close to the spike/exploration workflow we used to do at Pivotal Labs. I think he's right.

cc'ing @claudeai and @Lovable because I feel like it's a nice connection between the two of you <3
