## What it is
A curated set of recommended C code style rules and coding conventions for standard C99 or later, maintained by Tilen Majerle. It also ships an AI agent skill so AI coding assistants can write, edit, and format code according to the same rules.

## Use cases
- define a consistent C coding style for my team
- format C code according to a documented standard
- make my AI coding assistant follow C style rules
- learn best practices for writing C99 code
- set up coding rules for an embedded C project
- review C code against a style checklist

## When to choose
- you want a well-known, MIT-licensed C style guide to adopt as-is
- you work on embedded or general C projects and need consistent formatting rules
- you want AI agents to automatically conform to your C coding conventions

## When to avoid
- your organization already mandates a different standard like MISRA C or a company style guide
- you need an automated formatter tool rather than a written style document
- you work primarily in languages other than C

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: programming-languages, developer-tools, embedded-systems, tutorials
- platform: cross-platform
