At it's most basic, agentic mode is necessary for building the proper context. While I might know the solution at the high level, I need the agent to explore the code base to find things I reference and bring them into context before writing code.
Agentic mode is also super helpful for getting LLMs from "99%" correct code to "100%" correct code. I'll ask them to do something to verify their work. This is often when the agent realizes it hallucinated a method name or used a directionally correct, but wrong column name.
