Checkpoint

One last thing before we move on. Same surface as a write step — but the lesson doesn't complete until this passes.

Lesson one lock-in. The code sandbox runs Python, the language the rest of this course teaches. Same print and f-string move used in every chapter.

The starter declares three variables for the three parts of what a skill is. Write three print(f"...") lines so the output is exactly:

instructions: your playbook for one kind of task, written down once
packaged: a folder with a main file plus any supporting files
auto-loaded: claude pulls it in itself when the task matches

Type the three lines and run it.
