Please Do Not A/B Test My Workflow

A paying Claude Code user ($200/month) criticizes Anthropic for silently running A/B tests that degraded the tool's plan mode feature. The author discovered that a system-level instruction was hard-capping plans at 40 lines and forbidding context sections, without user notification or opt-out options. The post argues that professional developer tools require transparency and configurability, not consumer-app-style experimentation that disrupts established workflows.
