What is Agent Coding Tool?
A general-purpose AI coding agent that writes and edits code, with review or security scanning as one capability among many.
These are coding assistants first. Review and security features exist, but they sit beside code generation, refactoring and terminal work rather than being the product's centre of gravity.
They matter in this directory because they are increasingly the thing producing the code that everything else has to review, and because their review capabilities are real, if narrower and less consistently documented than a dedicated scanner's.
