What is –dangerously-skip-permissions in Claude Code?
Claude Code Permissions Explained
Claude Code uses a permission system to control which commands and file actions are allowed during operation. This safety mechanism helps prevent accidental or malicious changes by prompting the user before executing sensitive commands.
Permissions are configured to allow trusted commands automatically, while restricting or denying potentially harmful ones. The goal is to balance usability with security, especially when dealing with important files or directories.
YOLO Mode vs Auto-Accept Differences
The –dangerously-skip-permissions option, often called “YOLO mode,” disables all permission checks and prompts, allowing any command to run without restrictions.
In contrast, Auto-Accept mode only skips prompts for commands that have been pre-approved in the settings. It provides controlled convenience while keeping risky operations under control.
YOLO mode is much less safe because it bypasses ALL permission safeguards, meaning any command—safe or unsafe—runs automatically. This increases the potential for accidental damage or security breaches.
Why You Should Never Use –dangerously-skip-permissions in Home Directory
Home directory risks with Claude Code
The home directory is a critical part of your system, often containing important user files, configuration settings, and sensitive data such as API keys and secrets. Running Claude Code with –dangerously-skip-permissions in this directory exposes all these files to unregulated access.
Because this flag disables all permission checks, any command can modify, delete, or overwrite files in your home directory without warning. This puts your personal data and important configurations at risk, potentially leading to system instability or data loss.
Real-world dangers of skipping permissions
Bypassing permission checks may seem convenient, but the risks are very real. Some examples of potential dangers include:
- Unintended deletion of configuration files or API keys necessary for other applications
- Corruption of critical system or user files that could render your environment unusable
- Exposure of secrets and credentials if commands have unrestricted access
- Increased vulnerability to malicious commands or scripts running unchecked
These risks emphasize why using –dangerously-skip-permissions in your home directory or any directory containing important or unbacked data is strongly discouraged.
Safe alternatives to Claude –dangerously-skip-permissions
Configure Claude Code settings.json for permissions
Instead of disabling permission checks entirely, you can fine-tune your Claude Code environment using the settings.json file located in ~/.claude/. This configuration allows you to explicitly allow trusted commands and deny dangerous ones.
For example, you can permit safe Git operations like Bash(git:*) while excluding risky commands such as rm. This approach maintains a healthy balance between convenience and security, preventing accidental damage without unnecessary prompts.
Be sure to consult official documentation for correct syntax when editing these settings to avoid misconfigurations.
Claude Code sandbox and container best practices
Another recommended method is to run Claude Code inside controlled environments such as sandboxes or containers. These isolate the code execution from your main system and home directory, reducing the risk of unwanted file modifications or data leaks.
Using containers also allows you to set up precise permission scopes and resource limits, providing an extra layer of protection. This makes it safer to experiment or run complex commands without exposing your important files or secrets.
Claude Code security best practices
Claude permissions deny for sensitive files
For enhanced safety, explicitly deny permission for commands attempting to access or modify sensitive files and directories. Protect configuration files, API keys, and other secrets by adding them to deny lists in your permissions settings.
This proactive step blocks unauthorized attempts to change or read critical files, helping prevent security incidents before they happen.
AllowedTools and excludedCommands setup
Managing which tools Claude Code can invoke is essential. Define an AllowedTools list that includes only the safe, necessary utilities your tasks require. Simultaneously, add high-risk or unnecessary commands to excludedCommands.
This granularity helps minimize the attack surface, ensuring Claude Code operates within clearly defined and secure boundaries.
Frequently asked questions (FAQ)
When should you not use –dangerously-skip-permissions?
Never use it in home directories or anywhere with API keys, secrets, production configs, or unbacked data to avoid file deletion, system corruption, or security breaches.
What is the difference between Auto-Accept and YOLO mode?
Auto-Accept allows pre-approved commands without prompts; YOLO mode (--dangerously-skip-permissions) bypasses all checks, enabling unrestricted execution but increasing risks.
Why am I still seeing permission prompts with –dangerously-skip-permissions?
This may be a known bug; check GitHub issues or ensure the flag is correctly applied, as it should skip all prompts except denied commands.
How to configure permissions in ~/.claude/settings.json?
Edit allow and deny lists for commands like Bash(git:*), excluding dangerous ones like rm; check official docs for syntax.
Is it safe to use –dangerously-skip-permissions in directories with secrets?
No, avoid it entirely in directories with secrets, keys, or important data; use sandboxes or containers instead.
