What is the Address Sanitizer skill for Claude Code?

It is a specialized capability that allows Claude to guide developers in using AddressSanitizer (ASan) to detect memory safety errors in C and C++ code.

How do I implement these checks in my workflow?

Claude will provide guidance on the necessary compiler flags (such as -fsanitize=address) and environment configurations needed to instrument and test your binary.

Does this work with languages other than C and C++?

AddressSanitizer is primarily designed for C and C++ programs, though it can sometimes be used with other languages that interface with C libraries.

What types of bugs can this skill identify?

It identifies a wide range of memory errors including buffer overflows (heap, stack, and global), use-after-free, use-after-scope, and memory leaks.

Who created this skill?

This skill was authored by Trail of Bits, a premier cybersecurity firm, as part of their specialized testing handbook for developers.

安全与测试

Detects memory safety vulnerabilities and errors in C and C++ programs using AddressSanitizer instrumentation.

关于

The Address Sanitizer (ASan) skill empowers Claude to help developers identify and resolve critical memory safety bugs that frequently plague C and C++ applications. Developed by Trail of Bits, this skill provides specialized guidance for detecting use-after-free conditions, buffer overflows, and memory leaks. It is an essential tool for low-level systems programming, allowing for the proactive hardening of codebases against memory corruption exploits and ensuring long-term application stability through rigorous automated testing patterns.
