Book
The Crossroads of AI Integration.
800 pages across 50 chapters. Co-authored with Brian S. Gagne. AI foundations, agentic architectures, industry-specific playbooks, and implementation strategy — written for operators who have to actually ship the thing.
Amelia S. Gagne — CEO and co-founder of Kief Studio. Full-stack developer and strategist. Perplexity AI Business Fellow.
Brian S. Gagne — CTO and co-founder of Kief Studio. UPenn AI program alumnus and IBM-credentialed AI technologist. The technical depth alongside Amelia's operating and behavioral lens.
Together we run a two-person studio whose engineering output matches a 10–14 person team. The book is the long-form version of the methodology we use day to day.
Available via briansgagne.com — unified fulfillment.
Structure
What's inside
Eight parts plus appendices. Each part is self-contained — read end-to-end or skip to the section that matches the problem in front of you.
- Part I
AI foundations
How modern language models actually work, and the working vocabulary teams need before they make architecture choices.
- Part II
Prompting and orchestration
Prompt design, structured output, retrieval, evaluation — the operating layer that sits between models and product.
- Part III
Agentic architectures
Multi-agent patterns, tool use, planning loops, supervision. Where agents help and where they actively hurt.
- Part IV
Data, retrieval, knowledge systems
Grounding models in real data — embeddings, vector stores, hybrid search, the data engineering that nobody pitches at the keynote.
- Part V
Industry playbooks
Sector-by-sector implementations across healthcare, finance, legal, gaming, education, and more — what works, what fails predictably.
- Part VI
Security, governance, and risk
Threat modeling, prompt injection, data leakage, evaluation harnesses, and the boring discipline that keeps AI systems from leaking by default.
- Part VII
Implementation strategy
Operating models, team shape, build-vs-buy, vendor selection, governance — turning AI from a project into a capability.
- Part VIII
The road ahead
Where the field is going, what to bet on, what to ignore. Honest about the uncertainty.
- Part Appx
Appendices
Reference material — glossary, evaluation checklists, prompt and architecture patterns, further reading.
