Pitfalls

  • A decision model will not write the patch. It can grade one, or route the ticket to the agent.
  • The cheapest chat model with tools is not automatically the one that should merge code.

Sample prompt

You are a coding agent. Read the failing test, name the file you will change, then make the smallest edit that passes.
