Most developers wait until something breaks to think about security. This book is for the ones who have decided not to wait anymore.

Claude Mythos Mastery is the advanced practitioner's guide to building permanent, systematic, AI-powered security workflows that make vulnerability discovery a routine part of how you develop software - not a crisis response to a breach that already happened.

If you have already scanned a project, run a basic audit, or used AI tools to review code for security issues, this book is your next step. It shows you how to go beyond one-off assessments and build autonomous scanning systems, repeatable audit pipelines, and exploit-chain analysis workflows that function at a level of sophistication previously available only to dedicated security research teams.

What you will build:

Automated security scanning pipelines that run continuously against your codebasesAI-assisted exploit chain analysis workflows that identify how individual vulnerabilities combine into critical attack pathsCustom vulnerability triage systems that prioritise findings by exploitability, impact, and remediation costSystematic audit frameworks tailored to specific languages, frameworks, and architecture patternsDefensive patch review workflows that verify fixes resolve root causes rather than symptomsSecurity reporting pipelines that communicate risk accurately to technical and non-technical audiencesMonitoring systems that detect regressions and catch newly introduced vulnerabilities on each commit

This book is for the independent developer who wants to operate with the security sophistication of a dedicated red team - without the headcount. The tools exist. The methodologies exist. This book puts them together into a workflow you can build, own, and operate yourself.

Security at scale. No team required.
