A coding agent reads a repository, plans a change, edits files, runs tests and iterates until the task passes — instead of just suggesting snippets.

/ quick answer
A coding agent is an agent whose tools are a filesystem, a shell and a test runner. What separates a useful one from a demo is the feedback loop: it must be able to run the build and tests, read the failure, and correct itself. Without executable feedback, a coding agent is autocomplete with extra steps.
