gemini-cli
Google's terminal coding agent — reads your repo, edits files, runs commands, and connects to MCP tools.
Mature enough to put in production this quarter.
Any small team already shipping code; the generous free tier makes trying it a decision nobody needs to approve.
Part of a contract developer's hours on routine changes and test writing.
It will confidently edit files you did not intend to change. Run it in a repo with clean version control and review every diff.
Point it at your least-loved codebase and ask for tests on one module. Judge it on the diff, not the chat.
