C Master Skill

Use this skill for low-level C programming, memory management, and systems code:

When to Use

• Memory management: Manual allocation, preventing leaks, avoiding use-after-free
• Performance optimization: Cache-friendly code, reducing allocations, SIMD
• Systems programming: OS interfaces, device drivers, embedded systems
• Undefined behavior: Identifying and avoiding UB in C code
• Debugging: Memory corruption, segfaults, race conditions

Core Capabilities

1. Memory safety: Proper allocation/deallocation, bounds checking, ownership patterns
2. Performance tuning: Profiling, optimization, memory layout, compiler flags
3. UB detection: Recognizing undefined behavior, using sanitizers
4. Systems APIs: POSIX, system calls, low-level file I/O
5. Debugging techniques: GDB, Valgrind, AddressSanitizer, core dumps

Not For

• High-level application logic (use higher-level languages)
• Basic C syntax (already covered)
• Generic debugging
