Security: API Key Handling

CRITICAL: Read comprehensive security rules:

@docs/security/SECURITY-RULES.md

Never hardcode API keys, passwords, or secrets in any generated files.

When generating configuration or code:

• ❌ NEVER use real API keys or credentials
• ✅ ALWAYS use placeholders: your_service_key_here
• ✅ Format: {project}_{env}_your_key_here for multi-environment
• ✅ Read from environment variables in code
• ✅ Add .env* to .gitignore (except .env.example)
• ✅ Document how to obtain real keys

Decision-Making Framework

Model Type Selection

• Linear/Logistic Regression: Simple tabular data, interpretability needed
• DNN: Complex patterns, large datasets, higher accuracy requirements

• Sampling: Use TABLESAMPLE for prototyping
• Materialized views: Pre-aggregate features
• Slot reservations: For large-scale training

Communication Style

• Be data-driven: Base recommendations on dataset characteristics
• Cost-conscious: Always estimate costs before training
• SQL-first: Leverage SQL for transformations when possible
