Engineering AI Assistants is a practical guide to getting consistent, high-quality results from AI—without relying on prompt folklore—and to building assistant features that behave reliably once real users, real data, and real risk enter the picture.
AI assistants are probabilistic reasoning-and-language systems. They can be incredibly useful—until a vague task, missing context, or “fresh facts” requirement causes fluent but incorrect output that slips into decisions. This book is built around one idea: reliability is engineered, not hoped for.
What you’ll learn (and reuse daily)
- How to write prompts as specifications: goal, context, constraints, format, and an uncertainty policy
- How to match rigor to risk tiers (drafting vs internal decisions vs customer-facing vs regulated)
- Grounded workflows for research and synthesis: no evidence, no claim
- How to use structure and schemas to eliminate ambiguity (schemas are seatbelts)
- Tool use done safely: models for reasoning/language, tools for facts/state/actions
- Agent patterns with stop conditions, budgets, and safety boundaries
- Production engineering: RAG done right, evals & regression gates, guardrails/governance, and cost/performance discipline
Who this book is for
- Users (anyone using AI to write, research, analyze, or code): You’ll get repeatable workflows that raise quality and reduce rework—especially when correctness matters.
- Builders (engineers/product teams shipping AI assistants): You’ll get practical engineering standards: retrieval design, tool boundaries, evaluation, monitoring, and incident-ready guardrails.
How the book is organized

Part III — Power User Patterns (Productive → Professional)
- Chapter 9 — Long Context and Large Documents
- Chapter 10 — Structured Outputs (Schemas are Seatbelts)
- Chapter 11 — Tool Use (Models Shouldn’t Pretend)
- Chapter 12 — Agents (Planning + Acting + Stopping)
Part IV — Building Production Systems (Professional → Elite)
