Gdb

Walks Claude through interactive GDB sessions from basic breakpoints to reverse debugging and remote gdbserver workflows. Covers the essentials like stepping, inspecting variables, and multi-threaded debugging, plus less common terrain like Intel Processor Trace replay and conditional watchpoints. The command tables are dense enough to be reference material. Most useful when you're debugging a segfault or trying to diagnose a race condition and need Claude to suggest the right GDB invocations instead of generic advice. The prerequisite section on compiling with debug symbols will save you from the usual "no symbol table" frustration.
