The tool's Code Review product increased substantive pull request comments from 16% to 54%, and an internal Slack channel receives a new message every 5 to 10 minutes, with Claude Code autonomously fixing issues before human engineers can respond.", "body_md": "**Cat Wu**, who leads product for **Claude Code** and Cowork at **Anthropic**, said **90%** of Anthropic's own codebase is now written by `Claude Code`, according to an O'Reilly Radar writeup of her fireside chat with Addy Osmani at O'Reilly's AI Codecon. Per O'Reilly, Anthropic engineers are producing roughly **200%** more code than a year earlier, which shifted the team's bottleneck to code review; Anthropic's own separately released **Code Review** product reports substantive review comments on pull requests rose from **16% to 54%** after rollout. The article also describes an internal dogfooding Slack channel that gets a new message every **5 to 10 minutes**, and recounts an episode where a scheduled `Claude Code` task scanned that channel and opened a pull request to fix an issue before a human engineer got to it.", "url": "https://wpnews.pro/news/anthropic-s-claude-code-accelerates-developer-workflows", "canonical_source": "https://letsdatascience.com/news/anthropics-claude-code-accelerates-developer-workflows-f3e308d1", "published_at": "2026-07-03 19:39:32+00:00", "updated_at": "2026-07-03 21:09:07.595846+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools", "large-language-models", "generative-ai"], "entities": ["Anthropic", "Claude Code", "Cat Wu", "O'Reilly", "Addy Osmani", "Code Review"], "alternates": {"html": "https://wpnews.pro/news/anthropic-s-claude-code-accelerates-developer-workflows", "markdown": "https://wpnews.pro/news/anthropic-s-claude-code-accelerates-developer-workflows.md", "text": "https://wpnews.pro/news/anthropic-s-claude-code-accelerates-developer-workflows.txt", "jsonld": "https://wpnews.pro/news/anthropic-s-claude-code-accelerates-developer-workflows.jsonld"}}
