Summary

A viral tweet thread reveals a software engineer's productivity stack that routes tasks between frontier and cheap AI models in a loop, achieving the pace of a full team alone.

met a guy at Google making $1.2M a year. asked him how he ships alone at the pace of a full team. sent him what i've got. he didn't reply. sent me one folder. SAME MODEL - DIFFERENT RESULT. everyone's still picking between Opus and Fable like the model is the ceiling. it isn't. the real lever is what the loop wakes up into: planner → executor → judge → hitl-escalate → decisions.json → $LOOPKIT_CLI → /polish → finn-loop you stop feeding one model everything. you route the loop once. the loop routes the models. what's in his folder: - model-routing - plan frontier, act cheap, judge frontier. ~2x cheaper - hitl-escalate - loop stops, writes BLOCKED.md, waits for a human - pre-compact hook - decisions.json survives compaction - $LOOPKIT_CLI - same loop under codex, gemini, aider - /polish - one verb, six quality passes on the diff - suggest-next - feature_list refills itself - finn-loop preset - async /spec → ACK → /build → /review that's the stack. full breakdown in the article below. bookmark before he realizes i posted it.

met a guy at Google making $1.2M a year.

asked him how he ships alone at the pace of a full team. sent him what i’ve got.

he didn’t reply. sent me one folder.

SAME MODEL - DIFFERENT RESULT.

everyone’s still picking between Opus and Fable like the model is the ceiling. it isn’t.

the real lever is what the loop wakes up into:

planner → executor → judge → hitl-escalate → decisions.json → $LOOPKIT_CLI → /polish → finn-loop

you stop feeding one model everything. you route the loop once. the loop routes the models.

what’s in his folder:

  • model-routing - plan frontier, act cheap, judge frontier. ~2x cheaper
  • hitl-escalate - loop stops, writes BLOCKED.md, waits for a human
  • pre-compact hook - decisions.json survives compaction
  • $LOOPKIT_CLI - same loop under codex, gemini, aider
  • /polish - one verb, six quality passes on the diff
  • suggest-next - feature_list refills itself
  • finn-loop preset - async /spec → ACK → /build → /review

that’s the stack.

appreciate you finding this useful

keep grinding.

@ArchiveExplorer sometimes it’s not the model, it’s how you use it. dude probably has some crazy tricks up his sleeve. would love to see that folder!
