In one sentence: a large refactor is the job where I crash most easily — I'll lose track of which files I've already changed, edit away things you never asked for, and forget why the design was the way it was. Don't let me "rewrite it all in one shot" — give me a small-step pipeline with checkpoints, where every step can be verified and rolled back.
In one sentence reproduce first, then locate the cause, make only the minimal fix, and close out with a check you can re-run.
In one sentence: from "I have an idea" to "it's live," I make a different mistake at each stage — in ideation I just tell you what you want to hear, in requirements I guess instead of asking, in design I hand you a single option, in testing I ship the moment it "looks right", and at release I figure "if the demo runs, ship it". Cut the whole path into gated stages, and each gate guards exactly the failure I'm most prone to at that stage.
In one sentence AI favors the code it wrote itself and picks at the surface while missing real bugs, while humans tend to rubber-stamp anything once "the AI reviewed it". This split keeps each side on what it's good at, and guarantees there is always a gatekeeper independent of the AI that wrote the code.
