From the first page

A comprehensive, agent-optimized reference for building, reviewing, and securing web applications. Written as original content informed by deep study of the field's canonical works, OWASP standards, and current threat research.

This book is structured for AI agents that write, review, or audit web application code. Each chapter is self-contained — you can load any chapter independently without reading prior chapters.

Chapter structure: - Threat Summary — what this chapter covers (2-3 sentences) - Severity — CRITICAL, HIGH, MEDIUM, or LOW - Quick Reference — decision table or checklist - Core Rules — numbered, actionable principles - Examples — vulnerable code vs. secure code, annotated - Verification — how to confirm the fix works - Common Mistakes — anti-patterns to avoid

When to use this book: - Writing new web application code (check relevant chapters before implementation) - Reviewing code for security issues (use checklists as review guides) - Debugging security vulnerabilities (find the chapter matching the vulnerability class) - Designing authentication, authorization, or session management systems

Severity definitions: - CRITICAL — Direct path to full system compromise, data breach, or account takeover - HIGH — Significant security impact, exploitable without special conditions - MEDIUM — Security impact requires specific conditions or user interaction - LOW — Minor information disclosure or defense-in-depth concern
