Spec-Driven Development
Building Software From Clear, Executable Specs
Turn rough software requests into clear, testable work. This book shows how to define scope, non-goals, acceptance criteria, edge cases, contracts, and verification before coding begins—so human teams and AI coding agents can make smaller, safer, more reviewable changes.
Harness Engineering
Building Reliable AI Agent Systems
Harness Engineering shows how to build more reliable AI coding workflows. Learn how task briefs, repository guidance, context, tools, permissions, tests, evidence, and review gates help coding agents produce safer, more predictable software changes.
AI Skills for Builders
A Practical Guide to Building, Using, and Managing Agent Skills
Turn repeated AI work into reusable agent skills. This book helps builders understand where skills fit beside prompts, scripts, tools, MCP servers, and agents. Through practical examples such as release notes, support triage, security review, and document formatting, it shows how to design skills that stay focused, testable, and useful instead of becoming another folder of stale instructions.
Passkeys Explained
A Practical Guide to Passwordless Sign-In, Rollout, and Real-World Adoption
Learn what passkeys are, how passwordless sign-in works, and why they matter for safer online accounts. A practical guide to passkeys, account recovery, rollout decisions, and real-world adoption.
Passkeys for Developers
A Practical Guide to WebAuthn, Implementation, Testing, and Rollout
A practical developer guide to building passkey support with WebAuthn, from registration and sign-in to credential management, recovery, testing, and rollout. Includes a companion project that shows how passkeys fit into a real account system.
The 36 Stratagems for Software Teams
Ancient Strategy Patterns for Engineering, Product, Security, and Delivery
Ancient strategy for modern software decisions. The 36 Stratagems for Software Teams translates classic Chinese strategic patterns into practical lessons for engineering, product, security, platform, and delivery work — not as manipulation, but as a clearer way to recognize timing, leverage, risk, sequencing, and retreat.
Modern OAuth
A Practical Guide to OAuth 2.1, PKCE, Tokens, Scopes, and Secure API Access
Modern OAuth makes OAuth easier to understand in practical terms. Learn how delegated access, authorization code flow, PKCE, tokens, scopes, OpenID Connect, and secure API access fit together — and how to avoid common OAuth mistakes in web, mobile, SPA, and service applications.
Securing AI Applications
A Practical Guide to Securing Prompts, Retrieval, Tools, and Outputs
Build safer AI workflows with a practical, project-based guide to prompt injection, retrieval risks, tool permissions, output validation, approvals, redaction, and audit logs. Through the companion ai_security_lab project, this book shows how weak AI application boundaries can fail - and how to harden them step by step.
LLMs Explained
A Practical Guide to What Large Language Models Are, What They Do Well, and How To Use Them Wisely
Understand large language models beyond the buzzwords. This book helps readers see where LLMs fit beside prompts, tokens, context, RAG, tools, agents, safety, and evaluation. Through practical examples such as summarizing documents, improving prompts, checking answers, using structured outputs, and planning AI workflows, it shows how to use LLMs clearly and wisely instead of treating them as magic.
Building RAG Applications
A Hands-On Guide to RAG with Python
Build a practical RAG application with Python. Learn how retrieval, chunking, embeddings, reranking, citations, evaluation, and refresh workflows fit together in one small, inspectable project.
Building AI Agents
A Hands-On Guide to Goal-Driven Agents with Python
Build practical AI agents using a clear Python project. Learn how agent loops work, how to connect goals with tools and safety boundaries, and how to apply the same patterns to your own agent workflows.
Building MCP Servers
From First Tool to Real-World Workflows
Build real MCP servers using a practical Python project. Learn how Model Context Protocol works, how to design tools and workflows, and how to apply the same patterns to your own services.
AI Image Classification
Train Models Locally — A Hands-On Guide
Train your own AI image classification models — locally, simply, and without getting lost in theory. This hands-on guide shows you how to go from a folder of images to a working AI model you can understand, control, and use — all on your own machine.
QR Codes Explained
How QR Codes Work, How to Build Them, and How to Use Them Safely
Part of the Practical Tech Guide Series, this guide focuses only on what matters: how QR codes work at a high level, how to generate them, and how to use them effectively in real situations.
EXIF Data & Image Metadata
How to Analyze, Remove, and Protect Your Photos
Your photos may reveal more than you think. Every image you take can contain hidden data — location, device details, timestamps, and more. This information, known as EXIF and image metadata, is often shared without your awareness when you upload or send photos.
