About this chapter

You will learn

  • Everything read goes into the context
  • Search shows only the matching lines
  • Fewer tokens, same fix

Words you’ll meet

Search
A tool that returns only the lines holding some words, and which files they are in.
Context
Everything the agent has been shown so far, which it reads again each turn.
Token
The unit a model reads text in: here, about four bytes of code.
