An AI agent for understanding legacy code

What works, what goes wrong, and how to tell the difference.

Ask what a file does before asking it to change anything. An agent that has read the code gives a better answer than the last person who touched it three years ago.

How to check it

The rule that matters more than the tool: give the agent something that can prove it succeeded. A task with a test, a build or a linter attached comes back verified. A task with none comes back plausible, and plausible is the expensive kind of wrong.
