Chapter 5: CLAUDE.md and Project Scaffolding Patterns

Welcome to Chapter 5: CLAUDE.md and Project Scaffolding Patterns. In this part of Awesome Claude Code Tutorial: Curated Claude Code Resource Discovery and Evaluation, you will build an intuitive mental model first, then move into concrete implementation details and practical production tradeoffs.

This chapter covers how to adapt shared CLAUDE.md patterns into your local project standards.

Learning Goals

• identify reusable sections in existing CLAUDE.md examples
• separate universal guidance from project-specific constraints
• avoid brittle all-caps policy files that drift from reality
• evolve a living CLAUDE.md backed by real workflow evidence

Practical Template Pattern

Section	Purpose	Keep It Tight
coding standards	style, architecture, naming	only rules you enforce
test workflow	command set + pass criteria	exact commands
safety constraints	forbidden operations, data boundaries	explicit and auditable
contribution flow	branch/PR and verification expectations	aligned to real process

Source References

• CLAUDE.md Resources
• Official Documentation Resources

Summary

You now have a pattern for building maintainable CLAUDE.md guidance from curated examples.

scripts/maintenance/check_repo_health.py

The check_repos_health function in scripts/maintenance/check_repo_health.py handles a key part of this chapter's functionality:

def check_repos_health(
    csv_file, months_threshold=MONTHS_THRESHOLD, issues_threshold=OPEN_ISSUES_THRESHOLD
):
    """
    Check health of all active GitHub repositories in the CSV.
    Returns a list of problematic repos.

    deleted_repos = []

    logger.info(f"Reading repository list from {csv_file}")

    try:
        with open(csv_file, encoding="utf-8") as f:
            reader = csv.DictReader(f)

            for row in reader:

scripts/maintenance/check_repo_health.py

The main function in scripts/maintenance/check_repo_health.py handles a key part of this chapter's functionality:

scripts/resources/parse_issue_form.py
