**The Agentic Mental Model:** what "agentic" means and the loop, the context window as the governing constraint, explore→plan→implement→commit, verification, and precise prompting. Most engineers…
Right, because I think most of us initially treat these things like a, uh, like a smarter autocomplete.
Oh, absolutely.
You know, you write a function signature, you hit Tab, it finishes your line, and you just move on.
No, not at all.
To use it properly, you really have to understand what the word agentic actually means.
Yeah.
And that word is basically the defining characteristic of the tool.
The agentic loop.
Okay, break that down for us.
So it's this closed repeating cycle, right? Read, act, observe, iterate.
Read, act, observe, iterate.
Got it.
Right.
So when you give Claude Code a task, it doesn't just, you know, spit out a block of text for you to copy and paste.
It actively reads the files in your directory.
Wow.
Okay.
It runs terminal commands, it makes changes to the code base itself, observes the results of those changes, and then, and this is key, it iterates.
So it's doing the loop entirely on its own.
Exactly.
Continues that cycle autonomously until it decides, "Okay, the work here is done."
I mean, the analogy I keep coming back to is it's like the difference between a spellchecker and, like, an eager junior developer.
