TL;DR

The issue may be resolved by checking for updates or configuration changes in the Claude Code or Opus systems.

Guidance

  • Review the system logs and configuration files to identify any recent changes that may have caused the issue.
  • Compare the current system behavior with the expected behavior to pinpoint the specific problems with Opus not following user requests.
