A coding agent is an AI that reads, changes and tests code on its own and proposes changes for review.
Example
You describe a bug in a ticket; the agent finds the cause, writes a fix and opens a pull request.
For pros
Coding agents work in the terminal, the IDE or the cloud and run commands in a sandbox. Files such as AGENTS.md give them project rules. A person should review every change before merging, especially around security and dependencies.
