Reef Infra introduces GEPA recipe to generate prompt edits from failed model runs
1. Identify failed model runs where the LLM struggled with or fought specific prompt instructions. 2. Create a minibatch of these failed traces to serve as a training set for prompt reflection. 3. Use a secondary reflection model to analyze the failures and propose targeted rewrites to the prompt components. 4. Validate the newly edited prompt against the parent prompt on a fresh validation dataset to ensure the changes generalize well.

Guide details 16 prompt engineering patterns for production systems
1. Avoid relying on generic personas like 'world-class architect' to fix underlying logical errors in prompts. 2. Design prompts to maintain constraints and schema integrity across multi-turn API workflows. 3. Monitor and optimize token usage in long-running agent sessions to prevent cost explosions.
