Will this skill break my code examples by wrapping them?

No, the skill explicitly excludes code blocks, URLs, and tables from wrapping rules to ensure code remains functional and data remains structured.

Does this skill affect my project's README.md?

Typically no. This skill is specifically designed for Claude-facing documentation like CLAUDE.md and protocol files; human-facing docs usually have no strict limit.

Why is there a 110-character limit for documentation?

The 110-character limit ensures optimal readability for AI agents and maintains compatibility across various terminal interfaces and configuration parsers.

When should I use folded (>) versus literal (|) YAML syntax?

Use the folded style (>) for prose where you want newlines to become spaces, and the literal style (|) for commands or code where line breaks must be preserved.

Formats Claude-facing documentation and YAML frontmatter to adhere to specific line-length and syntax standards.

The Format Documentation skill provides standardized rules for structuring documentation intended for Claude and other AI agents. It enforces a 110-character line limit while intelligently handling YAML multi-line strings using folded and literal operators. The skill ensures markdown prose is wrapped at word boundaries without breaking sensitive elements like code blocks, URLs, or tables, making it essential for maintaining readable and syntactically valid project instructions, configuration files, and protocol documentation.
