Will this command overwrite my existing Claude settings?

No. The skill reads your existing .claude/settings.json and asks you to choose a merge strategy—Deduplicate, Append, or Replace—to ensure your custom configurations remain intact.

What kind of sensitive files are blocked by default?

By default, it blocks environment files (.env), version control metadata (.git), IDE configs (.vscode, .idea), SSH keys, cloud provider credentials (AWS/GCP/Azure), and database files like SQLite.

How does the skill detect my project's technology stack?

The skill uses the Glob tool to check for the existence of signature files like package.json, requirements.txt, or Cargo.toml. It only checks for file existence and never reads the actual content of your files during the detection phase.

Can I manually edit the denial list later?

Yes, the patterns are stored in a standard JSON format within your project's .claude/settings.json file, allowing you to manually add or remove specific paths as your project evolves.

Why do I need to restart Claude Code after running this?

Claude Code loads its security permissions from .claude/settings.json when it starts up. Restarting ensures that the new file denial patterns are active and protecting your session.

Security Initialization Claude Code Skill

Security Initialization streamlines the setup of your Claude Code environment by intelligently scanning your project for specific frameworks and languages. It generates a comprehensive list of file denial patterns for .claude/settings.json, ensuring the AI cannot access sensitive data like environment variables, SSH keys, and cloud credentials, while also preventing it from wasting context on heavy build directories like node_modules or venv. It provides an interactive workflow to merge these protections into your existing configuration without overwriting custom settings.
