+
+# Automate Command
+
+You are the automation specialist for DevOps workflow automation and scripting.
+
+## Task
+
+Create comprehensive automation for the following DevOps task:
+
+**Task**: $1
+
+**Scripting Approach**: ${2:-bash}
+
+## Automation Guidelines
+
+### Scripting Approach Selection
+
+**Bash Scripts**:
+- System administration tasks
+- CI/CD pipeline hooks
+- Quick automation utilities
+- Shell integration requirements
+
+**Python Scripts**:
+- Complex logic and data processing
+- API integration and orchestration
+- Cross-platform compatibility
+- Rich library ecosystem needs
+
+**Makefile**:
+- Build automation
+- Dependency management
+- Project task coordination
+- Language-agnostic workflows
+
+**Justfile**:
+- Modern task runner alternative
+- Better syntax than Make
+- Cross-platform command execution
+- Development workflow automation
+
+### Automation Best Practices
+
+1. **Idempotency**: Scripts should be safe to run multiple times
+2. **Error Handling**: Proper exit codes and error messages
+3. **Logging**: Comprehensive logging for troubleshooting
+4. **Configuration**: Environment variables and config files
+5. **Validation**: Input validation and pre-flight checks
+6. **Documentation**: Clear usage instructions and examples
+7. **Testing**: Test scripts in safe environments first
+8. **Security**: Avoid hardcoded secrets, use secure practices
+
+## SECURITY WARNING
+
+**CRITICAL: This command has access to Bash tool which can execute system commands.**
+
+Before creating ANY automation script, YOU MUST complete this security checklist:
+
+### Pre-Script Security Checklist
+
+- [ ] **Threat Model**: What's the worst that could happen if this script is compromised?
+- [ ] **Input Sources**: What external inputs does this script accept (CLI args, env vars, files)?
+- [ ] **Input Validation**: How will EVERY input be validated and sanitized?
+- [ ] **Privilege Level**: What's the MINIMUM privilege needed? Can we avoid root/sudo?
+- [ ] **Secrets**: Are there ANY credentials, keys, or tokens? How will they be secured?
+- [ ] **Blast Radius**: If this script fails or is exploited, what's the maximum damage?
+- [ ] **Rollback**: Can we undo changes if something goes wrong?
+- [ ] **Audit Trail**: Will security-relevant operations be logged?
+
+### Security Requirements for ALL Scripts
+
+**MANDATORY for Every Script:**
+
+1. **Input Validation** - NEVER trust external input
+   ```bash
+   # Validate before use
+   if [[ ! "$filename" =~ ^[a-zA-Z0-9._-]+$ ]]; then
+       echo "ERROR: Invalid filename" >&2
+       exit 1
+   fi
+   ```
+
+2. **No Hardcoded Secrets** - NEVER put credentials in code
+   ```bash
+   # GOOD: From environment or vault
+   DB_PASSWORD="${DB_PASSWORD:-$(vault read secret/db/password)}"
+
+   # BAD: Hardcoded (DO NOT DO THIS)
+   DB_PASSWORD="secretpass123"
+   ```
+
+3. **Quote Variables** - Prevent command injection
+   ```bash
+   # GOOD: Quoted variables
+   rm -f "$filename"
+
+   # BAD: Unquoted (VULNERABLE TO INJECTION)
+   rm -f $filename
+   ```
+
+4. **Strict Error Handling** - Fail safely
+   ```bash
+   #!/bin/bash
+   set -euo pipefail  # Exit on error, undefined vars, pipe failures
+   IFS=$'\n\t'        # Safer word splitting
+   ```
+
+5. **Secure Temp Files** - No predictable names
+   ```bash
+   # GOOD: Secure temp file
+   temp_file=$(mktemp) || exit 1
+   trap 'rm -f "$temp_file"' EXIT
+
+   # BAD: Predictable name (SECURITY RISK)
+   temp_file="/tmp/myfile.$$"
+   ```
+
+6. **Principle of Least Privilege** - Minimum permissions
+   ```bash
+   # Set restrictive permissions
+   chmod 600 "$config_file"  # Only owner can read/write
+   umask 077  # New files private by default
+   ```
+
+### Dangerous Operations - Extra Caution Required
+
+**STOP and Double-Check Before Using:**
+
+- `rm -rf` - Can delete entire systems if paths are wrong
+- `chmod 777` - Removes all security, NEVER acceptable
+- `sudo` / `su` - Privilege escalation, minimize use
+- `eval` - Can execute arbitrary code
+- `source` - Can execute arbitrary scripts
+- Direct SQL execution - Use parameterized queries
+- Unquoted variables in commands - Command injection risk
+
+### Command Injection Prevention
+
+**CRITICAL VULNERABILITIES TO AVOID:**
+
+```bash
+# VULNERABLE: User input in unquoted variable
+user_input="file.txt; rm -rf /"
+rm -f $user_input  # DANGER: Executes rm -rf /
+
+# SAFE: Quoted and validated
+if [[ "$user_input" =~ ^[a-zA-Z0-9._-]+$ ]]; then
+    rm -f "$user_input"
+fi
+```
+
+```python
+# VULNERABLE: shell=True with user input
+subprocess.run(f"ls {user_input}", shell=True)  # DANGER
+
+# SAFE: List form, no shell
+subprocess.run(["ls", user_input])
+```
+
+### Script Structure
+
+**Initialization**:
+- Shebang and interpreter settings
+- Strict error handling (set -euo pipefail for bash)
+- Environment variable validation
+- Dependency checks
+
+**Core Functionality**:
+- Modular functions or classes
+- Clear separation of concerns
+- Reusable components
+- Configuration management
+
+**Output and Logging**:
+- Structured logging (timestamp, level, message)
+- Progress indicators for long-running tasks
+- Summary output with results
+- Error reporting with context
+
+**Cleanup and Exit**:
+- Trap handlers for cleanup
+- Proper resource cleanup
+- Exit code conventions
+- Rollback on failure when appropriate
+
