Key Findings on Claude Code's Performance

As of April 20, Anthropic has addressed these issues and implemented measures to prevent future occurrences. The company has begun resetting usage limits for all subscribers, thanking users for their feedback on the platform.

User Reactions and Speculation

Many users expressed frustration over perceived declines in Claude Code's reliability. Users on GitHub and Reddit commented on the tool's recent performance, with some claiming it had become "lazy" and less competent in handling complex tasks.

Stella Laurenzo, a senior director at AMD, stated that Claude had regressed significantly. Another user, reporting similar sentiments, noted a marked decline since a specific change was made on March 4.

An Overview of User Experiences
