## Nauti's Take

Shipping source maps in a production build is the software equivalent of leaving your house key under the doormat – embarrassing, but fixable. More interesting than the mistake itself are the leaked features: a Tamagotchi-style pet for a coding assistant sounds absurd, but could be a clever gamification strategy to boost developer engagement. The always-on agent is the truly relevant signal – Anthropic is clearly moving toward autonomous, persistently running AI workflows, which raises new questions about security, cost, and control.
