Prompt Engineering in Practice [Davies] - mklabgr - 09-23-2026
Prompt Engineering in Practice by Richard Davies and Rafael Fischer presents prompt engineering as a software-engineering discipline rather than casual trial-and-error prompting. The central idea is to treat prompts as engineered interfaces that combine clear instructions, context, constraints, input parameters, delimiters, and expected output formats. The authors emphasize that good prompts should be self-contained, precise, reusable, testable, and maintainable, much like APIs or other software components.
The book then develops a practical lifecycle—Design, Test, Iterate, Manage—for building reliable LLM applications. It covers reusable prompt patterns, zero-shot and few-shot/contextual prompting, systematic diagnosis of inconsistent outputs, prompt libraries and version control, and security issues such as prompt injection and jailbreaks. Its overall goal is to move AI development from experimental prompts that happen to work toward production-grade prompts that can be evaluated, debugged, secured, and maintained over time.[/url]
