Coding agent
Last updated June 29, 2026 · by Tal Gerafi
A coding agent is an AI system that performs software tasks end to end — reading code, running commands, editing files, and checking results in a loop — instead of only suggesting code for a human to copy.
A coding agent closes the loop that a code-completion tool leaves open. Autocomplete suggests the next line; a coding agent takes a goal, changes the project, runs the build or tests, reads what happened, and iterates until the task is done.
How it works
The agent is built on a large language model but adds the ability to act: it can open and edit files, run shell commands, and observe results. That feedback loop — act, check, correct — is what lets it handle multi-step work like "add this page and make the build pass" rather than producing a snippet that may or may not fit.
Why it matters for B2B sites
Coding agents are the engine behind AI-assisted web development. They shorten the distance between a request and a working change, which is decisive for a small team. But the same autonomy that makes them fast makes review non-negotiable: an agent can confidently ship something wrong, so a person should approve consequential changes. Claude Code is the coding agent Greeto uses to build client sites.
