A builder documented the ChatGPT-plans-it, Claude-implements-it loop.

An r/SaaS post details a concrete cross-model workflow: ask ChatGPT how a real developer would fix the bug, have it write the plan into bugfix.md, hand that file to Claude to implement, then ask Claude for a deep review. Anecdotal, single source. What's interesting is that the model-as-specialist pattern is propagating organically among non-expert builders rather than being prescribed by tooling. The file handoff is the clever bit. It's a poor man's phase gate, which is the same primitive Anthropic used to get 165K lines migrated for 27 million tokens.
