Overview
About This Skill
Varlock Skill wraps the Varlock CLI to enforce secure environment variable handling within Claude Code sessions. It prevents secrets from leaking into terminal output, Claude's input/output context, log files, or git commits by validating variables against a schema file and masking sensitive values. Users can safely check if secrets are present, validate configuration, and run commands with injected secrets without exposing values. The skill is ideal for development teams, DevOps engineers, and operations staff who need to work with API keys, database credentials, and other sensitive data while using Claude for coding assistance.
How to Use
Install the Varlock CLI, then add the skill via one-liner or manual git clone. Create a .env.schema file to define variable types and sensitivity levels. Use 'varlock load' to validate secrets (values masked), 'varlock load --quiet' for silent checks, or 'varlock run -- [command]' to execute with secrets injected.
Use Cases
Validate all environment variables are set without exposing their values
Debug authentication issues by confirming secrets exist (masked)
Run development servers with injected secrets safely
Prevent accidental exposure of API keys in Claude context

Usage Examples
Prompt Template
I'm working in a Claude Code session for [COMPANY], a [INDUSTRY] company. I need to securely manage environment variables containing sensitive [DATA] information. Can you help me set up and use the Varlock skill to handle this securely?
Example Output
# Secure Environment Variable Management Setup
## Current Environment Variables
- `DB_PASSWORD`: ******
- `API_KEY`: ******
- `AWS_SECRET`: ******
## Secure Variable Usage
```python
import os
# Accessing variables securely
password = os.getenv('DB_PASSWORD')
api_key = os.getenv('API_KEY')
# Using variables in secure operations
def secure_operation():
# Your secure operations here
pass
```
## Security Confirmation
✅ All environment variables are properly masked in outputs
✅ No sensitive data appears in terminal or logs
✅ Secure access methods are in placeApply to these tools
