Anthropic's Claude Code team shares insights on AI coding tools and prompt design

Simon Willison conducted a conversation with the Anthropic team behind Claude Code where they discussed developing coding agents, testing, and internal tool usage. Among the findings: Claude Tag (Slack integration) contributes to 65% of pull requests, and system prompts are significantly reduced (80% smaller) as newer models require fewer examples.

WHY IT MATTERS

This demonstrates how Anthropic itself uses and iterates on its AI tools, and provides practical insight into modern prompt engineering that challenges established best practices. The findings on system prompts have direct relevance for anyone building with Claude models.
