[Bug] Context Management Degradation in Claude Code Workflow

Bug Description
Context dwindles very quickly despite manual attempts at a context management strategy through a minimized Claude.md. CC performance degraded quickly today - CC fixed problems only to reverse those changes and create new problems. It was a bad day compared to 2 better days prior.
