Prompt Engineering for Agents, Production Grade

Description and use

<blockquote> <p><em>Throughout the AI System Design series we follow Mailmind, a fictional AI email assistant that reads an inbox, triages messages, and drafts replies. It is our running example.</em></p> </blockquote> <p>In Part 4, you gave your agent hands. Now you need to tell it exactly what to do with them. Prompt engineering for agents is not about writing clever chat messages. It is about embedding constraints, decision frameworks, and output schemas into the system prompt so the agent’s behavior is deterministic across runs. A single missing constraint can cause an agent to send an ema
