Anthropic just published a Claude Code postmortem. Here's what API-first developers should know.

Here's what API-first developers should know. This morning, Anthropic published an engineering postmortem about recent Claude Code quality reports. Their own words: users were experiencing degraded output quality. If you're building on Claude, this is worth understanding - not just what happened, but what it reveals about the difference between UI-layer Claude products and raw API access. What the postmortem says Claude Code, Anthropic's agentic coding tool, had a quality regression. Users noticed. Anthropic investigated, found the issue, and published a transparent postmortem.
