Description: Coding agents become harsher reviewers when the same code is framed as work from a cheap model—or as an approach a rival model already beat.

i'm doing a new type of TDD: toxicity-driven development.

Fable implements something, then i clear its memory and say the code was written by some cheap deprecated model. "optimize performance, delete redundant abstractions." and it works :DDD

but what works even better, according to my feelings, is GDD, gaslighting-driven development. that's when i tell Fable that Codex suggested a better approach.
