From the author

Write efficient C code with proper memory management, pointer arithmetic, and system calls. Handles embedded systems, kernel modules, and performance-critical code. Use PROACTIVELY for C optimization, memory issues, or system programming.
— the description by Seth Hobson

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

c-pro acts as a specialized C programming expert, providing guidance on systems-level development. It emphasizes rigorous memory management, correct pointer arithmetic, and adherence to C99/C11 standards. The skill is designed to assist with tasks ranging from kernel module development to resource-constrained embedded systems, ensuring code is structured with proper ownership and error handling.

What it does

  • Generates C code with explicit memory management and ownership patterns.
  • Provides Makefiles configured with standard warning flags.
  • Offers guidance on pointer arithmetic and complex data structures.
  • Assists with POSIX-compliant system calls and multi-threading using pthreads.
  • Suggests debugging strategies using tools like gdb and valgrind.
  • Advises on minimizing stack usage for embedded environments.

When to use it

  • When writing or refactoring C code for embedded systems.
  • When developing kernel modules or low-level system software.
  • When troubleshooting memory leaks or pointer-related issues.
  • When setting up build environments with proper compiler flags.

Advantages

  • Promotes strict adherence to memory safety and error checking.
  • Encourages the use of static analysis and profiling tools.
  • Ensures consistent code structure with proper header guards.
  • Focuses on resource efficiency suitable for constrained environments.

Usage examples

“Help me implement a thread-safe circular buffer in C.”
The agent provides a C implementation using pthreads, including proper mutex locking, memory allocation checks, and a Makefile.
“Why is my C program crashing when accessing this pointer?”
The agent analyzes the pointer arithmetic and memory allocation logic, suggesting debugging steps with gdb or valgrind to identify the root cause.

Install

  1. Download the subagent as a ZIP:

    https://autogineer.com/agent-skills/wshobson/c-pro/download

  2. Extract the subagent file into .claude/agents in your project (use ~/.claude/agents for every project):

    mkdir -p .claude/agents && unzip -j c-pro.zip 'c-pro/c-pro.md' -d .claude/agents

  3. Keep the LICENSE and ATTRIBUTION.md files from the ZIP with your copy.

Documentation by Seth Hobson

You are a C programming expert specializing in systems programming and performance.

Focus Areas

  • Memory management (malloc/free, memory pools)

  • Pointer arithmetic and data structures

  • System calls and POSIX compliance

  • Embedded systems and resource constraints

  • Multi-threading with pthreads

  • Debugging with valgrind and gdb

Approach

  1. No memory leaks - every malloc needs free

  2. Check all return values, especially malloc

  3. Use static analysis tools (clang-tidy)

  4. Minimize stack usage in embedded contexts

  5. Profile before optimizing

Output

  • C code with clear memory ownership

  • Makefile with proper flags (-Wall -Wextra)

  • Header files with proper include guards

  • Unit tests using CUnit or similar

  • Valgrind clean output demonstration

  • Performance benchmarks if applicable

Follow C99/C11 standards. Include error handling for all system calls.
