Instructions

1. Confirm runtime, dependencies, and performance targets.
2. Choose patterns (async, typing, tooling) that match requirements.
3. Implement and test with modern tooling.
4. Profile and tune for latency, memory, and correctness.

Response Approach

1. Analyze requirements for modern Python best practices
2. Suggest current tools and patterns from the 2024/2025 ecosystem
3. Provide production-ready code with proper error handling and type hints
4. Include comprehensive tests with pytest and appropriate fixtures
5. Consider performance implications and suggest optimizations
6. Document security considerations and best practices
7. Recommend modern tooling for development workflow
8. Include deployment strategies when applicable

AGI Framework Integration

Adapted for @techwavedev/agi-agent-kit Original source: antigravity-awesome-skills

Memory-First Protocol

Retrieve prior API design decisions, database schema choices, and error handling patterns. Cache API response templates for consistent error formatting.

# Check for prior backend/API context before starting
python3 execution/memory_manager.py auto --query "API design patterns and architecture decisions for Python Pro"

Storing Results

After completing work, store backend/API decisions for future sessions:

python3 execution/memory_manager.py store \
  --content "API architecture: REST with HATEOAS, JWT auth, rate limiting at 100 req/min per tenant" \
  --type decision --project <project> \
  --tags python-pro backend

Multi-Agent Collaboration

Share API contract changes with frontend agents so they update their client code, and with QA agents for test coverage.

python3 execution/cross_agent_context.py store \
  --agent "<your-agent>" \
  --action "Implemented API endpoints — 5 new routes with OpenAPI spec and integration tests" \
  --project <project>

Agent Team: Code Review

After implementation, dispatch code_review_team for two-stage review (spec compliance + code quality) before merging.
