Day 20 — Make Your AI Agent Get Better: The Feedback Loop
Most AI agents repeat the same mistake forever, because the correction lives in your head, not the agent. Here's the four-move feedback loop that turns a tool into a teammate: every run it shows its work, asks one question, you correct it once in plain English, and the note persists into the next run. From the @ImplexaAI build-solo series.
Most people build an AI agent, watch it get something wrong, fix that one run by hand… and then watch it make the exact same mistake the next day. Forever. Because the correction lived in their head, not in the agent.
The difference between a tool and a teammate is a loop. Here's how to build it.
The loop, in four moves
1. Every run, the agent shows its work. Not just "done" — the actual draft, the actual list, the actual post. You can't correct what you can't see.
2. It asks you one question. "Was this the right call?" One question, answerable in a tap or a sentence. Don't make reviewing it a chore, or you'll stop reviewing.
3. You correct it once — in plain English.
"Lead with their first name." "Skip anything under ten grand." "Make it shorter."
No config files, no retraining. Just tell it, the way you'd tell a new hire.
4. The correction persists into the next run. This is the part almost everyone skips — and it's the whole point. The note can't vanish when the run ends. It gets saved and fed into the next run, and the one after that. So you never say the same thing twice.
What this feels like over time
- Day one: your agent is a confident intern. Right often, wrong sometimes, eager.
- Three weeks in: it's doing the job your way, in your voice, with your judgment calls baked in — without being told again.
One correction a day compounds. A month of one-tap corrections is a teammate that knows how you work.
The real mistake
It isn't building an agent that's wrong sometimes — everything is, at first. The real mistake is building one that can't learn from being told. If a correction doesn't survive the run, you don't have a teammate. You have a tool that resets every morning.
How I do it
I tell Claude Code, in plain English, to show its work each run and remember my notes. It runs inside my own Claude — no credentials handed to anyone, nothing to install. The corrections ride into the next run on their own.
That's the loop. Build it once, coach it once a day, and your agent stops being something you babysit and starts being something that gets better while you do other things.
