One flag. Zero interruptions. Maximum trust. Use it wisely — there's "danger" right in the name for a reason.
Let's have an honest conversation.
Permission prompts exist for good reason. When an AI assistant wants to delete files, run system commands, or modify your codebase, you probably want to know about it. Safety matters. Guardrails protect you.
But.
There are times when you trust Claude. When you're in a sandbox environment. When you're doing exploratory work and the constant "Are you sure?" prompts slow you down more than they protect you. When you just want to say "yes to everything" and let Claude work.
For those moments, Claude Code offers YOLO mode. And yes, it's exactly what it sounds like.
The Problem
Claude Code, by default, asks for permission before taking potentially impactful actions:
- Creating or modifying files
- Running terminal commands
- Accessing certain system resources
- Making changes that could be difficult to undo
This is good behavior. You want an AI that checks before it acts.
But in certain contexts, these permission prompts become friction:
Rapid prototyping: You're building a throwaway proof-of-concept. Every "Allow Claude to create file.js?" slows your momentum.
Automated workflows: You're running Claude in a script or CI pipeline. There's no human to click "approve."
Sandboxed environments: You're in a Docker container or VM specifically designed to be destroyed. Who cares what Claude does?
Deep flow states: You've built trust through a long session. You're confident in Claude's judgment. The prompts interrupt your concentration without adding safety.
Learning and exploration: You're explicitly asking Claude to show you things, try approaches, create examples. You want it to just do the thing.
In these situations, the safety prompts aren't protecting you — they're slowing you down.
The Solution
Enter the flag that trusts Claude unconditionally:
claude --dangerously-skip-permissions
With this flag, Claude Code says yes to everything. No prompts. No confirmations. No friction.
How to Use It
Starting Claude Code in YOLO mode:
claude --dangerously-skip-permissions
That's it. From this point on, Claude will execute actions without asking.
Combining with other flags:
# Resume a named session without permission prompts
claude --dangerously-skip-permissions --resume refactor-sprint
# Start in a specific directory
claude --dangerously-skip-permissions --cwd ~/projects/sandbox
What This Actually Means
With YOLO mode enabled:
| Action | Normal Mode | YOLO Mode |
|---|---|---|
| Create file | "Allow Claude to create...?" → You approve | Just creates it |
| Delete file | "Allow Claude to delete...?" → You approve | Just deletes it |
| Run command | "Allow Claude to run...?" → You approve | Just runs it |
| Modify code | "Allow Claude to edit...?" → You approve | Just edits it |
The mental model: Claude operates with the same access as if you were typing the commands yourself.
⚠️ The "Danger" Part
Let's be absolutely clear: this flag is called --dangerously-skip-permissions for a reason. The word "dangerously" is intentional.
Things that can go wrong:
- Claude could delete files you didn't expect
- Commands could have unintended side effects
- Mistakes are applied immediately without a chance to catch them
- You lose the ability to review before changes happen
This is NOT for:
- Production codebases without version control
- Systems with sensitive data
- Environments you can't easily restore
- Situations where you're not paying close attention
- Multi-tenant systems where Claude's actions could affect others
This IS for:
- Sandboxed development environments
- Proof-of-concept work
- CI/CD pipelines with proper safeguards
- Personal projects where you trust your rollback ability
- Sessions where you're actively watching Claude work
The judgment is yours. The consequences are also yours.
Pro Tips
🎯 Tip 1: Use version control religiously. YOLO mode is 100x safer when git reset --hard can undo anything Claude does.
# Before YOLO mode, ensure you're on a clean branch
git checkout -b experimental-yolo
git status # Should be clean
claude --dangerously-skip-permissions
🎯 Tip 2: Use dedicated sandbox environments. Docker containers, VMs, or cloud dev environments (like GitHub Codespaces) are perfect for YOLO mode. Blow them away if things go wrong.
🎯 Tip 3: Start focused sessions. YOLO mode works best when you have a clear, bounded task. "Refactor this module" is better than "improve the codebase."
🎯 Tip 4: Stay engaged. YOLO doesn't mean "start it and walk away." Watch what Claude is doing. You can still interrupt if something looks wrong.
🎯 Tip 5: Create a shell alias for sandboxes.
# In your .zshrc or .bashrc
alias claude-yolo="claude --dangerously-skip-permissions"
alias claude-sandbox="cd ~/sandbox && claude --dangerously-skip-permissions"
Real-World Use Case
Let's see YOLO mode in action with two scenarios:
Scenario 1: Rapid Prototyping
Casey is exploring a new library. They want Claude to create a demo project, install dependencies, write example code, and run tests — all quickly.
cd ~/scratch
mkdir library-exploration && cd library-exploration
git init
claude --dangerously-skip-permissions
You: Create a complete demo project for the XYZ library. Include
installation, a basic example, and three test cases.
Claude: [Creates package.json, installs dependencies, writes src/index.js,
writes tests/basic.test.js, runs npm test — all without prompts]
What would have been 10 permission prompts becomes a smooth, uninterrupted flow. And if anything goes wrong? rm -rf library-exploration and start over.
Scenario 2: Automated Workflows
A team uses Claude Code in their CI pipeline for automated code review suggestions. No human in the loop during execution.
# .github/workflows/claude-review.yml
- name: Claude Code Review
run: |
claude --dangerously-skip-permissions << EOF
Review the changes in this PR. Create a file called
REVIEW_NOTES.md with your findings.
EOF
Permission prompts would break this workflow. YOLO mode enables automation.
The Philosophy of Trust
YOLO mode represents a fundamental truth about tools: sometimes safety features become obstacles.
It's the same reason sudo exists. The same reason git has --force. The same reason editors have "disable all warnings" options. Sometimes you know what you're doing, and you need your tools to get out of the way.
The flag's naming is perfect: it doesn't hide the risk. It puts "dangerously" right there where you can't miss it. It's a conscious choice, not an accidental one.
Use it when appropriate. Avoid it when not. Your judgment, your call.
Conclusion
YOLO mode is power without guardrails. It's Claude Code trusting you to know when you need it and when you don't.
For sandbox environments, rapid prototyping, CI pipelines, and focused exploration — it removes friction that doesn't add safety. For production systems and sensitive data — it removes safety that you desperately need.
The flag has "danger" in the name. Respect that. Then, when the time is right, use it anyway.
claude --dangerously-skip-permissions
YOLO.
