Debugging optimized builds skill for diagnosing issues in release code. Use when debugging RelWithDebInfo builds, using -Og for debuggable optimization, working with split-DWARF, applying GDB scheduler-locking, reading inlined frames, or understanding "value optimized out" messages. Activates on queries about debugging optimized code, RelWithDebInfo, -Og, inlined functions in GDB, value optimized out, GDB with -O2, or debugging release builds.
Core dump analysis skill for production crash triage. Use when loading core files in GDB or LLDB, enabling core dump generation on Linux/macOS, mapping symbols with debuginfo or debuginfod, or extracting backtraces from crashes without re-running the program. Activates on queries about core files, ulimit, coredumpctl, debuginfod, crash triage, or analyzing segfaults from production binaries.
C++20 coroutines skill for understanding coroutine mechanics and debugging. Use when working with co_await, co_yield, co_return, implementing promise_type, understanding coroutine frame layout, debugging suspended coroutines in GDB, or inspecting frame allocation with Compiler Explorer. Activates on queries about C++20 coroutines, co_await, co_yield, promise_type, coroutine_handle, coroutine suspension, or coroutine frame.
FreeRTOS skill for embedded RTOS development. Use when creating tasks, managing priorities, using queues and mutexes, detecting stack overflows, configuring FreeRTOS via FreeRTOSConfig.h, or debugging FreeRTOS applications with OpenOCD and GDB. Activates on queries about FreeRTOS tasks, queues, semaphores, mutexes, configASSERT, stack overflow, vTaskDelay, or FreeRTOS-aware debugging.
GDB debugger skill for C/C++ programs. Use when starting a GDB session, setting breakpoints, stepping through code, inspecting variables, debugging crashes, using reverse debugging (record/replay), remote debugging with gdbserver, or loading core dumps. Activates on queries about GDB commands, segfaults, hangs, watchpoints, conditional breakpoints, pretty-printers, Python GDB scripting, or multi-threaded debugging.
x86-64 assembly skill for reading, writing, and debugging assembly code. Use when reading GCC/Clang assembly output, writing inline asm in C/C++, understanding the System V AMD64 ABI calling convention, or debugging register and stack state. Activates on queries about x86-64 assembly, AT&T vs Intel syntax, inline asm, calling conventions, SIMD intrinsics, or reading disassembly output from objdump or GDB.
RISC-V assembly skill for RV32/RV64 programming. Use when working with the RISC-V ISA, calling conventions (psABI), inline assembly with GCC/Clang, understanding extension naming (IMAFD), compressed instructions, or simulating RISC-V with QEMU and GDB remote debugging. Activates on queries about RISC-V assembly, RV32, RV64, RISC-V calling convention, RISC-V inline asm, RISC-V extensions, QEMU RISC-V, or RISC-V GDB.
Debug and trace C/C++/Rust programs with the GNU Debugger (GDB) without blocking the agent. Use when you need to set tracepoints, inspect variables, or monitor a running process while staying responsive to the user.
