Code examples for the AI Engineering Skills: Prompt, Context, Harness, Loop tutorial. Files live in the ai-engineering-layers/ top-level folder, named after the article slug.

The project is a small Flask checkout API that's broken on purpose (four bugs, five failing tests), plus loop.py, which hands the failures to Claude Code one test at a time. Verified locally with Python 3.12.3, flask==3.1.3, and pytest==9.1.1: python -m pytest -q gives 5 failed, and loop.py with a stand-in claude reaches all tests passing after 4 runs. Running it for real needs a logged-in Claude Code (flags match 2.1.308).

Please don't fix the app's bugs in review: they're the demo.
