Who should use this skill?

Security researchers, software developers, and auditors who need a comprehensive understanding of a codebase before attempting to find vulnerabilities.

How does it improve security audits?

By building context first, it prevents surface-level analysis and ensures bug finding is grounded in the actual structural logic and data flow of the code.

Is this skill part of a larger workflow?

Yes, it is typically used as a foundational step before using tools like Semgrep, CodeQL, or specialized variant analysis skills.

Who created this skill?

The skill was created by Trail of Bits, a premier cybersecurity research and consulting firm known for high-end security auditing.

What is the Audit Context Building skill?

It is a specialized capability developed by Trail of Bits that enables Claude to perform deep, line-by-line code analysis to understand application architecture.
