Before you start: Read the Field Manual first; be comfortable with Python functions and tests.

Plan for 6–10 hours of hands-on work in addition to reading. This is an initial estimate; setup and extensions vary.

Preview 1

How This Connects to the Field Manual

Same universe, different job. Read the other guide first if you haven't — this one assumes it.

Preview 2

The Context Window Budget

Every token in the window is rent someone is paying — in dollars, in latency, and in the model's attention.

Preview 3
