Claude just shipped a self-tuning agent framework that rewrites your prompts + tools automatically.

Real prod results:
• 2.5x fewer failures
• 6x cheaper
• 2x faster runtime

All tested on unseen convos. Open source.

This is the meta-agent play everyone's been waiting for. Your AI literally optimizes itself now.

If you're building agents and still hand-tuning prompts in 2025, you're ngmi.
