Demo app: tasks

A deliberately tiny command-line task tracker. It exists to be changed by an AI, so it's small enough to read in a minute but real enough to have more than one file, which is exactly where the copy-paste workflow starts to hurt.

This is the running example for Module 1 (where you feel the copy-paste problem) and Module 2 (where you put it under version control).

Files

• tasks.py: the core logic (Task, TaskList).
• cli.py: the command-line front end. Reads/writes tasks.json.

Run it

python3 cli.py add "read module 1"
python3 cli.py add "set up my editor"
python3 cli.py list
python3 cli.py done 0
python3 cli.py list

Requires Python 3.10+ (it uses list[Task] style type hints). No third-party packages.
