An AI coding tool should fit your repository, review process, and development environment. Test a small bug fix, a change with meaningful tests, and an unfamiliar part of the codebase before giving it broader access.

## TL;DR
Keep accountable human review for changes that will ship. Passing tests does not establish that a change handles every edge case, protects data, or follows your team’s architecture.

## What matters when comparing AI coding assistants?
Start with a representative task and the people who will do it. Evaluate repository access, generated-code correctness, test quality, command permissions, and review effort. Test the same inputs across your shortlist and record output quality, manual work, and current plan terms.

## Evaluation checklist
- Use a repository you are authorised to share with the selected service.
- Compare generated changes on correctness, maintainability, and test coverage.
- Inspect command execution, network access, and approval controls.
- Measure review and correction work alongside initial implementation time.

## Do coding agents replace code review?
Keep accountable human review for changes that will ship. Passing tests does not establish that a change handles every edge case, protects data, or follows your team’s architecture.
