- license:
- MIT
- compatibility:
- C11 baseline. Tools: CMake/CTest or Make. Debugging: gdb/lldb (Linux/macOS), MinGW gdb + objdump (Windows), MSVC dumpbin + WinDbg (Windows). Optional: sanitizers (Clang/GCC), fuzzing (libFuzzer/AFL where supported).

C Testing
Pragmatic workflow for reliable C tests and bug-finding.
When to activate
- Adding unit tests for C functions
- Building a small test harness around a module
- Debugging failing tests or memory corruption
- Enabling sanitizers or fuzzing to reproduce crashes
Core rules
- Keep unit tests deterministic and isolated.
- Avoid real network/time in unit tests.
- Run ASan/UBSan in CI for memory and UB signal.

VerifiedTrustedCommunity
Offensive methodology for authorized game security assessments, game client security research, and game-adjacent penetration testing in real-world engagements. Use when assessing game clients for cheating vulnerabilities, testing anti-cheat effectiveness, auditing game server protocols for score manipulation or economic fraud, reverse engineering game DRM or license validation, analyzing game save file protection, or assessing game mod/plugin security. Covers: process memory scanning and manipulation (Cheat Engine methodology), game binary reversing for license and DRM bypass, game network protocol analysis and packet replay, anti-cheat mechanism analysis, save file format reversing and tampering, speed hack and value injection techniques. Does NOT cover: CTF game challenges (game-ctf), game engine source code auditing (web-exploit-technique or vuln-search-technique for the backend), or general binary exploitation (pwn-ctf or reversing-technique).
