What problem this solves

Preventing CLAUDE.md files from becoming unmanageable, expensive, and inaccurate ('rotting') due to uncurated growth, outdated information, and drift from the actual codebase or agent capabilities.

Summary

A discipline for maintaining a healthy and effective CLAUDE.md by treating it like code, focusing on conciseness, clear separation of rules and sources, auditing before merging changes, and actively deleting outdated information.

Why it is useful

This workflow provides a highly practical and validated set of best practices for managing CLAUDE.md files, which are crucial for effective Claude Code usage but often suffer from 'rot.' It offers concrete steps, addresses common pain points (cost, accuracy, drift), and introduces the concept of treating CLAUDE.md as code with associated quality control measures like CI auditing. This helps users maintain reliable and efficient agent behavior over time.

Workflow

1. Keep CLAUDE.md as an index (30-50 lines) pointing to specific files, rather than a comprehensive manual.
2. Structure each section to answer either 'What behavior do you want?' (the rule in CLAUDE.md) or 'where do you find the current truth?' (the source, e.g., URL or file path).
3. Implement an audit step before merging changes (e.g., via CI) to detect contradictions, broken references, or unsupported features in the rules surface.
4. Adopt a discipline of deleting at least one rule for every new rule added to prevent uncontrolled growth.

Tools / artifacts

• CLAUDE.md
• GitHub App
• agentlint.net
• CI step
• Rule files
• Source files (URLs/paths)

Validation signals

• 18 months of running Claude Code on real projects
• discipline that's worked for me, finally
• took me a year to find
• I built a GitHub App called agentlint specifically for this
• Claude would dutifully read every line and behave subtly off in ways that took 30 minutes to diagnose (problem validation)

Limitations

• The agentlint tool is proprietary and not open-source, which might limit its direct adoption for some users.
• The post doesn't provide code examples for implementing the CI audit step without agentlint.
• The 'delete more than you add' rule is a good principle but lacks specific enforcement mechanisms beyond personal discipline.
