Arize Builders Meetup - Seattle - Boosting Claude Code performance with prompt learning

​​Your CLAUDE.md file is more powerful than you think. In this talk, we'll walk through how we applied Prompt Learning — an RL-inspired prompt optimization technique — to improve Claude Code's performance on SWE-Bench Lite by up to 11%, purely by optimizing the system prompt instructions. No fine-tuning, no new tools, no architecture changes. Just better prompts, driven by real performance data and LLM-as-a-judge feedback.

​​We'll cover the full optimization loop (rollouts → LLM evals → meta-prompting), show results for both general coding improvement and repo-specific specialization, and share practical takeaways you can apply to your own coding agent workflows today.
