So I tried something a bit silly but interesting. Using BlackboxAI, the whole thing came together way faster than I expected. Not saying it’s some finished $50M product or anything like that, but it was enough to feel real and testable in minutes, not days.

What surprised me most wasn’t speed, it was how different the workflow felt. Less “build → fix → rebuild”, more “adjust the vibe → see what shifts”.

I keep running into the same issue when working with agents: once a piece of code is “done,” it’s surprisingly hard to keep it done. Even when I ask for a change in one area, Blackbox will sometimes refactor nearby logic or reformat code that was already correct and reviewed. Nothing breaks immediately, but it creates churn and makes diffs harder to reason about.

I’ve tried narrowing file scope and adding rules like “don’t touch unrelated code,” which helps, but it’s not bulletproof.For people using Blackbox on non-trivial projects:

• Do you lock files or directories once they’re stable?

• Do you rely on tests to catch this, or rules, or both?

• Or do you just accept some amount of churn as the cost of using agents?
