When should I use a subdirectory CLAUDE.md?

Use them only when a directory has more than 5 files and contains local conventions or non-obvious constraints that differ from the project-wide standards.

What is the main purpose of a CLAUDE.md file?

It serves as a curated set of guardrails and pointers that help Claude understand project-specific constraints and commands that it cannot infer from the code itself.

How long should a CLAUDE.md file be?

A root CLAUDE.md should typically be between 100-200 lines. If it exceeds 300 lines, it should be audited for bloat to prevent context dilution.

Why should I exclude standard language conventions from CLAUDE.md?

Claude already knows standard framework and language conventions; including them wastes valuable context space and can distract from the unique rules of your specific project.

What should I do if my instructions are too long?

Move domain-specific knowledge into a separate Skill or use a Rule with path frontmatter for file-type-specific constraints instead of cluttering the main CLAUDE.md.

학습 및 문서화

Optimizes AI performance by establishing lean project guardrails, critical constraints, and essential developer commands within CLAUDE.md files.

The CLAUDE.md Authoring skill provides a specialized framework for creating and auditing highly efficient project-level instruction files. Rather than treating documentation as a manual, this skill focuses on defining critical constraints, non-obvious architecture patterns, and essential commands that Claude needs to operate effectively within a specific codebase. It helps prevent context dilution by ensuring every line in your CLAUDE.md adds specific value, resulting in faster and more accurate AI-driven development through optimized guardrails.
