Anthropic's Claude Code team says Claude writes about 90 percent of the product's code and that most review now runs through automated layers before humans look.

In an October 16, 2026 post on its Claude blog, the team says merged pull requests more than doubled from June to September while reverts fell by more than 40 percent.

The team says human approvals are scaled to each change's risk and that it tracks revert and incident rates as guardrails. These figures come from Anthropic itself, and the post cites no independent verification.
