Guide to Setting Up Safety Layers for Coding with Claude Code

Practical Safety Setup for AI-Assisted Coding

A Reddit user has published a detailed guide on implementing defense-in-depth safety layers when coding with Claude Code. The guide assumes zero prior experience and provides a complete setup that takes about 30 minutes to implement.

Key Safety Layers

The guide covers five specific safety layers:

• Pre-commit hooks using detect-secrets, ruff, pyright, and bandit for automated code quality and security checks before commits
• CLAUDE.md files to teach Claude your project's specific conventions and coding standards
• Local review agents for deeper code analysis beyond basic linting
• GitHub Actions CI with automated Claude code review on every pull request
• Branch protection to make all checks mandatory before merging code

The implementation is Python-focused with examples, but the architecture applies to any programming language. The guide walks through each layer with specific setup instructions.
