Can this skill help with ASAN faults?

Yes, it includes specific workflows for navigating AddressSanitizer (ASAN) crashes to find the exact application instruction causing the memory corruption before the runtime error occurs.

What is rr debugging?

rr is a tool that records program execution so you can replay it deterministically, allowing you to step backward and forward through code to find the exact cause of a bug.

Does it support reverse execution?

Yes, the skill provides specific commands like reverse-next, reverse-step, and reverse-continue to backtrack from a crash point in time.

What are the benefits of deterministic debugging over standard GDB?

Standard GDB only moves forward; this skill enables 'time-travel' debugging, ensuring that every replay is identical and allowing you to see how variables reached their state before a crash.

セキュリティとテスト

Automates deterministic debugging and reverse execution to identify root causes of program crashes and memory faults.

概要

This skill integrates the rr record-replay tool into Claude Code, enabling developers and security researchers to perform non-flaky, 'time-travel' debugging of complex crashes. By recording program execution and replaying it deterministically, it allows the agent to step backward from a crash point to see exactly how memory became corrupted or where logic failed. It includes specialized workflows for standard crashes and AddressSanitizer (ASAN) faults, making it an essential tool for high-stakes software debugging and security research.
