🛡️ Step-by-Step Safety Guide: Responsible Prompt Engineering

Step 1: Environment Setup & Authentication

# Clone the repository securely
git clone https://github.com/YouMind-OpenLab/awesome-nano-banana-pro-prompts.git

# Verify integrity
cd awesome-nano-banana-pro-prompts
git log --show-signature

# Install dependencies
npm install --only=prod

# Set up API keys (NEVER commit these!)
echo "GEMINI_API_KEY=your_key_here" > .env
echo ".env" >> .gitignore

Safety Check: Always use environment variables, never hardcode credentials.

Step 2: Prompt Sanitization Protocol

Before using any prompt:

1. Scan for PII leakage: Run the included sanitize-prompt.js script

   node scripts/sanitize-prompt.js --input "your-prompt.txt"
   

2. Check for bias indicators: Use the built-in bias detector

   const { auditPrompt } = require('@nano-banana-pro/safety');
   const riskScore = auditPrompt(promptText);
   if (riskScore > 0.7) {
     console.warn("Prompt requires human review");
   }
   

3. Validate image prompts: Ensure no celebrity names or copyrighted styles are used without permission

Step 3: Rate Limiting & Cost Management

// Implement exponential backoff
const { withRateLimit } = require('@nano-banana-pro/utils');

const safePromptCall = withRateLimit({
  maxRequests: 60, // per minute
  costPerToken: 0.0001,
  budgetAlert: 100 // $100 warning threshold
});

await safePromptCall(() => gemini.generate(prompt));

Step 4: Output Filtering

// Always filter AI responses
const { ContentFilter } = require('@nano-banana-pro/safety');

const filter = new ContentFilter({
  blockPolitics: true,
  blockMedicalAdvice: false, // Set based on your use case
  profanityThreshold: 0.3
});

const safeOutput = await filter.clean(aiResponse);

Step 5: Logging & Audit Trail

// Maintain audit logs for compliance
const { AuditLogger } = require('@nano-banana-pro/compliance');

logger.log({
  promptId: 'nano-123',
  userId: 'user-456',
  timestamp: new Date(),
  input: sanitizedPrompt,
  outputHash: hash(safeOutput),
  riskScore: 0.2
});

Step 6: Multilingual Safety Considerations

• Never use machine translation for sensitive prompts
• Always have native speakers review high-risk categories (medical, legal, financial)
• Test cultural appropriateness with the built-in cultural-audit tool
• Monitor for language-specific prompt injection attacks
