 ## Introduction
 
-In the world of AI coding, agents like Claude Code or Codex rely on "function calling" (where the AI asks "the harness" to read a file, waits for the tool to respond, then reads another). CWC flips this! By providing files upfront the model has everything it needs from the start, so you can save time and tokens.

-Although selecting files for every task sounds like a chore, it builds codebase understanding, maintains coding skills and lets you prompt the model with simpler, easier to iterate on instructions.

CWC flips this by letting you pick files upfront from a file tree you already know and love, so that the model has everything it needs from the start.

-> Not sure what to select? CWC can help you reliably find relevant files using a dedicated prompt type.
