Two people can use the exact same model on the exact same day and end up with completely different results. One gets something usable, the other gets junk. That gap is almost never the model. Output quality tracks the context you hand it. That's the one variable that decides almost everything else. I run a stack of automation pipelines, and Claude Code is the tool I build and operate them with. One of my pipelines went quiet for a while because a script read a field one level too deep in a JSON payload. Every row came back empty instead of throwing an error, so it looked like a slow day instead of a broken one. The fix wasn't in the tool, it was in what the code assumed about its input. Prompts fail the same way. Context, in practice, means: → What the output needs to look like, and how you'll know it's good enough → A reference: an example, a page, a file, whatever shows the direction → What absolutely must not happen → Where the material it needs to work with actually lives None of that is extra work you're doing to be careful. It's the work that comes back anyway, as a correction round, if you skip it. What do you hand your AI before you let it start?
