Claude Code pushes engineering efficiency from "manpower growth" to "capability growth"!

Boris Cherny mentioned an interesting change here: After the release of Claude Code, the amount of code and the number of PRs within Anthropic increased significantly.

The 3x that he had publicly mentioned before was already outdated data in his opinion, and the real improvement was even higher.

What’s more important is for newcomers to ramp up.

As traditional engineering teams grow larger, the productivity of individual engineers usually decreases: communication increases, context becomes heavier, and newcomers need to keep asking old employees.

But at Anthropic, onboarding time has dropped from a few weeks to about two days.

This shows that the value of coding agents is not just “writing more code”, but also reducing the cost of knowledge transfer when the team expands.
