Action required by April 30, 2026.

Claude 4.6 Broke Our Production Agent in Two Hours — What's Worth the Migration

Model upgrades are supposed to make things better. Claude 4.6 did — eventually — but not before breaking production agent integrations in ways that caught teams completely off guard.

Anthropic Is Banning Claude OAuth in Third-Party Tools — OpenClaw Users Hit by 403 Errors and a Policy Shift

Anthropic is actively and deliberately revoking OAuth token access for Claude Pro and Max subscriptions in third-party applications. OpenClaw is among the affected platforms. This isn’t just a version regression or a temporary outage. Multiple independent sources — a Medium post documenting a full migration away from Claude, an analysis on daveswift.com, and a GitHub commit trail — all confirm this is a deliberate policy shift. ...
