An AI coding agent is an AI system connected to a development environment. It can read files, modify code, run tools, and use feedback from tests or errors.
In practice
Coding agents are useful for tasks that span multiple files or require investigation. They can help with bug fixes, feature work, migrations, documentation, test generation, and code review.
What to watch
Agents need the same discipline as human changes: clear requirements, version control, tests, and review before production deployment.
