C Development

WHEN: Writing or reviewing C code, native libraries, embedded components, POSIX tools, or C interfaces where memory layout, portability, and deterministic runtime behavior matter.

When to Use This Skill

• Building native C libraries and command-line tools
• Implementing embedded or systems-level components
• Designing FFI-safe interfaces for other languages
• Hardening pointer-heavy or buffer-heavy code
• Modernizing legacy C to safer, clearer patterns
