A coding agent for small, well-scoped fixes

Let an agent take on bug fixes and small changes in a sandboxed copy of your code, with a person reviewing every change.

Difficulty: AdvancedTime to pilot: 1 weekBest for: Small teams with a code repository and tests

Know what "good" means

Coding agents are commonly measured on SWE-bench, which tests whether a model can resolve real GitHub issues. Compare current models on the independent Artificial Analysis leaderboards before you choose.

How to set it up

Give the agent a branch, never your main branch, plus your test suite. Every change goes through review like any teammate's pull request.

For private code, a local coding model such as Qwen2.5-Coder (offered in sizes from 0.5B to 32B on Ollama) can handle smaller tasks on your own hardware.

Watch out for

Agents can confidently ship wrong code. Require passing tests, keep changes small, and don't give an agent production credentials.
