Core Concepts & Rules

1. Core Principles

• Follow established patterns and conventions
• Maintain consistency across codebase
• Document decisions and trade-offs

2. Implementation Guidelines

• Start with the simplest viable solution
• Iterate based on feedback and requirements
• Test thoroughly before deployment

Quick Start / Implementation Example

1. Review requirements and constraints
2. Set up development environment
3. Implement core functionality following patterns
4. Write tests for critical paths
5. Run tests and fix issues
6. Document any deviations or decisions

# Example implementation following best practices

def example_function():
    # Your implementation here
    pass

Assumptions

• LLM supports function calling (GPT-4, Claude 3 Opus+)
• Functions are idempotent or handle retries appropriately
• Network connectivity for external services
• Sufficient memory for concurrent function execution

Compatibility

• Python 3.8+
• OpenAI API 1.0+ (for function calling)
• Anthropic API 1.0+ (for tool use)
• Pydantic 2.0+ (for validation)
• Asyncio 3.7+ (for parallel execution)

Test Scenario Matrix (QA Strategy)

Technical Guardrails & Security Threat Model

1. Security & Privacy (Threat Model)

• Top Threats : Injection attacks, authentication bypass, data exposure

• Data Handling : Sanitize all user inputs to prevent Injection attacks. Never log raw PII

• Secrets Management : No hardcoded API keys. Use Env Vars/Secrets Manager

• Authorization : Validate user permissions before state changes

2. Performance & Resources

• Execution Efficiency : Consider time complexity for algorithms
• Memory Management : Use streams/pagination for large data
• Resource Cleanup : Close DB connections/file handlers in finally blocks

3. Architecture & Scalability

• Design Pattern : Follow SOLID principles, use Dependency Injection
• Modularity : Decouple logic from UI/Frameworks

4. Observability & Reliability

• Logging Standards : Structured JSON, include trace IDs request_id
• Metrics : Track error_rate, latency, queue_depth
• Error Handling : Standardized error codes, no bare except
• Observability Artifacts :
  • Log Fields : timestamp, level, message, request_id
  • Metrics : request_count, error_count, response_time
  • Dashboards/Alerts : High Error Rate > 5%

Agent Directives & Error Recovery

(ข้อกำหนดสำหรับ AI Agent ในการคิดและแก้ปัญหาเมื่อเกิดข้อผิดพลาด)

• Thinking Process : Analyze root cause before fixing. Do not brute-force.
• Fallback Strategy : Stop after 3 failed test attempts. Output root cause and ask for human intervention/clarification.
• Self-Review : Check against Guardrails & Anti-patterns before finalizing.
• Output Constraints : Output ONLY the modified code block. Do not explain unless asked.

Definition of Done (DoD) Checklist

• Tests passed + coverage met
• Lint/Typecheck passed
• Logging/Metrics/Trace implemented
• Security checks passed
• Documentation/Changelog updated
• Accessibility/Performance requirements met (if frontend)

Anti-patterns

1. No Validation : Not validating function parameters
2. No Error Handling : Functions can fail - handle gracefully
3. Hardcoded Schemas : Not using proper schema definitions
4. No Caching : Re-executing same functions wastes resources
5. No Rate Limiting : Exceeding API limits
6. Ignoring Context : Not using previous function results
7. No Streaming : Not streaming long responses
8. Insecure Code Execution : Allowing arbitrary code execution
