Advanced Prompt Engineering with Claude AI

Your prompt engineering stopped working the day Claude got smarter, and your production pipeline is paying for it.

The techniques that worked on last year's Claude now overtrigger tools, hallucinate details, or quietly break your JSON parser. Nobody sent you the memo when the rules changed.

Advanced Prompt Engineering with Claude AI is the technical field guide built for exactly this shift. It covers system prompts, XML tag structuring, and schema-guaranteed structured outputs. No filler, no beginner theory.

Built for Opus 4.8, Sonnet 5, and Fable 5, not techniques written for a model two generations old. You already know how to talk to Claude. This book teaches you to engineer prompts it actually obeys in production.

Inside, you will learn how to:

• Write system prompts that hold their instructions for fifty turns, not just the first five
• Structure prompts with XML tags so Claude never confuses your instructions with your examples
• Guarantee valid JSON every time with schema-constrained structured outputs, no more parser crashes
• Calibrate reasoning depth with the effort parameter instead of guessing at token budgets
• Build AI agents that call tools reliably and know when to run in parallel
• Track state across long running agentic tasks using git commits and structured files
• Cut hallucinations with grounding techniques that force Claude to quote its sources before answering

This is not a beginner tutorial rehashing basic chat prompts. It is written for developers already shipping Claude powered products who need every response to hold up under real traffic. Fourteen chapters, no filler, covering everything from system prompts to long running agentic workflows.

Become the Claude developer whose prompts still work six model releases from now.
