Our review

Provides expertise in building safe, modular, and performant systems using C with a focus on procedural Clean Architecture.

Strengths

Emphasizes modular design through opaque pointers and header encapsulation.
Enforces strict memory safety rules including buffer bounds and mandatory NULL checks.
Encourages explicit error handling via return codes rather than exceptions.
Offers structured guidance with prioritized rules for idioms and error handling.

Limitations

Relies on internal rule files not provided in the skill overview.
Does not cover object-oriented or modern C++ patterns.
May require additional context for cross-platform or embedded specifics.

When to use it

When developing or refactoring C codebases that demand high reliability, maintainability, and strict adherence to memory safety practices.

When not to use it

When working with higher-level languages, rapid prototyping, or projects where C's low-level control is unnecessary.

Security analysis

Safe

Quality score85/100

This skill is a C development guide that focuses on safe coding practices like memory safety, modular architecture, and buffer safety. It does not instruct any execution of commands, network access, or file operations, and it does not contain any obfuscated or dangerous content. The skill is purely advisory for code generation, with no direct runtime risk.

Examples

Create a safe queue module

Write a C module for a generic queue using opaque pointers, Clean Architecture layering, and all memory safety practices (bounds checking, NULL checks, length-bounded functions).

Refactor unsafe string handling

Refactor this C code to replace all unsafe string functions (strcpy, strcat) with their length-bounded equivalents (strlcpy, strlcat) and add proper buffer size checks.

Implement error handling with return codes

Explain how to implement consistent error handling in C using explicit return codes and errno, with examples for a file I/O library following Clean Architecture principles.

Rule Categories

| Priority | Category | Impact | | :--- | :--- | :--- | | 1 | C Idioms | HIGH | | 2 | Error Handling | MEDIUM |

Core Expertise

Modular Architecture: Opaque pointers, header encapsulation, and clear layering.
Memory Safety: Strict ownership rules, buffer safety, and mandatory NULL checks.
Procedural Patterns: Struct-based "methods" and explicit return codes.

Instructions for the Agent

Consult Internal Rules: Always refer to the rules/ directory within this skill for C-specific idioms and error codes.
Modularize: Use headers to define interfaces and source files for private implementations.
Buffer Safety: Strictly avoid unsafe string/buffer functions; use length-bounded alternatives.
