Hacker News·high signal

A GitHub issue documenting Claude Code becoming 'unusable for complex engineering tasks' has exploded to 1,130 points and 622 comments on Hacker News. A quantitative analysis of 17,871 thinking blocks and 234,760 tool calls across 6,852 session files reveals that the rollout of thinking content redaction (redact-thinking-2026-02-12) correlates with measurable quality regression — convention adherence degraded, tool usage shifted from research-first to edit-first behavior. This is the highest-engagement Claude Code story in months and signals serious developer trust erosion at Anthropic.
