A Fireside Chat with Cat and Thariq from the Claude Code team

- Claude Tag lands 65% of product engineering PRs for the Claude Code team at Anthropic.
- Claude Code features are first tested internally and only shipped if they demonstrate user retention.
- System prompts for frontier models (e.g., Opus 4.8, Fable) have been reduced by 80%; giving examples and 'don't do' lists is no longer best practice.
- Auto mode in Claude Code is heavily evaluated and enables safe, long-running agent tasks; it also powers Claude Tag.
- Critical code changes are still manually reviewed, but automated code review handles outer layers after building trust through evals.
- Fable can one-shot many features including editing video, and performing complex multi-step tasks.
- To offset the feeling of loss from coding automation, Thariq advises being more ambitious with the work you take on.
- Anthropic's culture of working in public (e.g., public Slack channels) and 'ant fooding' (dogfooding) are key to successful tool adoption.
- Non-engineers use Claude Tag for searching company knowledge, checking metrics, and asking about features without coding.
