If you have used Claude or ChatGPT for a while and the output feels fine but generic, that is not a skill problem. It is an input problem. Your agent isn't underpowered, it's underfed. It shows up two other ways. You know your field cold and none of it accumulates anywhere. Or you already got one agent working and you want the next thing to make that one better instead of competing with it. Same fix in all three. There's a lesson at the top of Start Here: Your First Handoff called The One File That Makes Every Agent You Use Sound Like You. It builds one file, your Context Card, out of material you already have sitting around. It takes about twenty minutes and needs nothing paid, nothing installed, and no credentials. Open the lesson, run it, then paste what you get into an agent you already use and watch the answer change. A Handoff is giving repeated work away. An agent carries it. The judgment stays yours. When you're done, come back here and reply with the one line from your file that actually surprised you.
