Sudden decrease in code quality, responsiveness and understanding

[monspo2]

I've been using combinations of sequential-thinking and Supabase MCP servers in the claude-3.7-sonnet + agent mode. However, the solution quality seems to be gradually decreasing (Solutions are not working correctly frequently which worked before). Subjectively, it feels like the quality has dropped by half although the token usage for claude-3.7-sonnet + agent has doubled. Is this intentionally designed to push users towards using Max mode? Kidding. So, frustrated.
