Where are the global permission settings stored?

User global settings are stored in ~/.claude/settings.json, which has the lowest priority in the configuration hierarchy.

Are 'deny' rules sufficient for protecting secrets and API keys?

No, deny rules are primarily workflow controls and can be bypassed. For robust security of credentials, you should use PreToolUse hooks.

How does Bash command matching work in the configuration?

Bash permissions use prefix-only matching. For example, 'Bash(git status)' will match 'git status' and 'git status --porcelain'.

What is the precedence for Claude Code permission rules?

Rules follow a strict precedence order: Deny rules take the highest priority, followed by Ask rules, and finally Allow rules.

How do I block Claude from reading my node_modules folder?

Add "Read(node_modules/**)" to the 'deny' section of your settings.json file to manage resources and save tokens.

Configures Claude Code tool permissions and security rules to control access to files, commands, and web tools.

This skill provides specialized guidance for managing Claude Code permissions within your settings.json file, implementing best practices for allow, ask, and deny rules. It helps users navigate the configuration hierarchy—from global to project-specific settings—while ensuring a balance between developer productivity and system security. Users can learn to implement workflow guardrails for destructive commands, optimize token usage by blocking heavy directories like node_modules, and understand the critical distinction between workflow controls and true security mechanisms like PreToolUse hooks.
