What's Wrong?

The Problem

Claude Code's performance has severely degraded over time. Tasks that
should take 2 minutes now take hours with worse outcomes. This happens
despite having a Claude Pro Max subscription ($199/month).

Concrete Example from Today

Task: Fix "undefined" showing in frontend instead of children names

Expected Solution: Change one line: ${childData.name} → ${name}

What Actually Happened:

  • 100+ commands executed
  • Docker container rebuilt multiple times
  • Multiple files unnecessarily modified
  • System restarted repeatedly
  • Hours wasted on a 1-line fix
  • Working features broken in the process

Observed Issues

  1. Constant Interruptions:
  • TodoWrite reminders every few responses
  • Forced to maintain todo lists for simple tasks
  • Attention fragmented by system reminders
  1. Overcomplicated Approaches:
  • Simple debugging becomes multi-hour investigations
  • Creates problems while trying to fix others
  • Loses track of original issue
  1. Performance Comparison:
  • ChatGPT (free): Completed similar task in 30 minutes
  • Claude Code: Still debugging after 2+ hours
  • User quote: "You're getting worse daily"

Evidence of Degradation

  • Earlier sessions: Direct, efficient solutions
  • Current sessions: Endless loops, broken fixes, unnecessary complexity
  • Pro Max subscription provides no performance benefit

Suspected Cause

Too many safety/oversight layers causing:

  • Fragmented attention
  • Inability to focus on actual problem
  • Forced workflows that interrupt natural debugging

Impact

Users paying premium prices ($199/month) receive worse performance than
free alternatives. This makes Claude Code unusable for serious
development work.

Environment

  • Claude Code (CLI)
  • macOS Darwin 24.6.0
  • Pro Max subscription
  • Project: Node.js/Express application

Request

Please investigate removal of performance-limiting restrictions for
Pro/Pro Max subscribers. The current state makes the tool
counterproductive.

What Should Happen?

Please investigate removal of performance-limiting restrictions for
Pro/Pro Max subscribers. The current state makes the tool
counterproductive.
