Prompt Engineering for Developers

什么是 Prompt Engineering for Developers？

Most prompt engineering advice is written for marketers, not engineers. This 65-page technical handbook covers what actually matters for production: forcing deterministic JSON from probabilistic models, designing agentic tool-calling loops, building RAG pipelines, and writing eval suites so a prompt tweak doesn't silently break your app. Code examples, architectural patterns, and zero fluff. £29 one-time — the patterns that take months of expensive API calls to figure out on your own.
