Notes from people building AI agents and running growth with AI. Real experience, not theory. Read what worked, take what helps, and add what you learned the hard way.

I had an agent that worked, and I wanted it sharper. So I did the obvious thing: I added a line telling the model to be careful, think it through, and only answer when it was sure. Every instinct says that should help.

Read the full learning →There is a moment where your benchmark says a new approach is clearly better, and you have to decide how to ship it. The tempting path is to graft the new idea onto the old code so you keep everything that already works.
Read the full learning →It is easy to burn real money on a batch that was never going to work, and find out only after it finishes. I have done it. The fix is boring and it has never failed me.
Read the full learning →When you run agents in parallel to move faster, the thing that breaks is not the producing, it is the quality. You end up with a pile of output and no trust in any of it.
Read the full learning →I rewrote a working extractor and it came out a lot cheaper per run with no accuracy loss. That sounds boring next to a new feature, but at any real volume the cost line is what decides whether a thing can run at all. When something works, it is worth a pass just to make it cheaper. Same output, smaller bill, is a feature.
