Professor Profiler - Feature Checklist

✅ Course Requirements Met

1. Multi-Agent System ✓

  • Hub-and-Spoke Architecture: Root orchestrator (professor_profiler_agent) + 3 specialized sub-agents
  • Sequential Agents: Taxonomist → Trend Spotter → Strategist workflow
  • Agent Powered by LLM: All agents use Google Gemini 2.0 (Flash/Pro)
  • Parallel Processing Ready: Batch question classification infrastructure
  • Agent Delegation: Root agent delegates specialized tasks

Files:

  • profiler_agent/agent.py - Root agent
  • profiler_agent/sub_agents/taxonomist.py
  • profiler_agent/sub_agents/trend_spotter.py
  • profiler_agent/sub_agents/strategist.py

2. Tools ✓

  • Custom Tools:
    • read_pdf_content: PDF text extraction
    • analyze_statistics: Statistical analysis
    • visualize_trends: Chart generation
    • compare_exams: Multi-exam comparison
  • MCP Integration Ready: Extensible FunctionTool wrapper
  • Built-in Tools Ready: Code execution support (infrastructure in place)

Files:

  • profiler_agent/tools.py - Custom tool implementations
  • google/adk/tools/function_tool.py - Tool wrapper with Gemini integration

3. Long-Running Operations ✓

  • Pause/Resume Support: Session-based state preservation
  • Checkpoint System: Session service stores intermediate results
  • Async Streaming: Event-based execution with run_async

Files:

  • google/adk/runners/runner.py - Async runner with streaming
  • google/adk/sessions/in_memory_session_service.py - State management

4. Sessions & Memory ✓

  • InMemorySessionService: Full session lifecycle management
    • Create, read, update, delete sessions
    • Message history tracking
    • Context/state management
  • Memory Bank: Long-term storage
    • Exam analysis history
    • Student preferences
    • Study plan tracking
  • Context Compaction: Smart summarization for token limits

Files:

  • google/adk/sessions/in_memory_session_service.py - Session management
  • profiler_agent/memory.py - Memory bank implementation

5. Observability ✓

  • Structured Logging: JSON logs with correlation IDs
  • Distributed Tracing: Request flow tracking with spans
  • Metrics Collection:
    • Counters (events, successes, errors)
    • Gauges (current values)
    • Histograms (distributions, percentiles)
  • Performance Monitoring: Execution time tracking

Files:

  • profiler_agent/observability.py - Complete observability stack

6. Agent Evaluation ✓

  • Integration Tests: Comprehensive test suite
  • Component Testing: Individual agent/tool validation
  • End-to-End Testing: Full workflow validation
  • Performance Metrics: Execution time tracking

Files:

  • tests/test_agent.py - Test suite
  • demo.py - Comprehensive demo with validation

7. A2A Protocol (Ready for Implementation) 🔄

  • Agent Communication Infrastructure: Message passing via context
  • Sub-agent Invocation: Root agent → Sub-agent protocol
  • Response Aggregation: Combining sub-agent outputs
  • External A2A: Ready for inter-system agent communication

Notes: Internal A2A implemented via sub-agent architecture. External A2A can be added via REST/gRPC endpoints.

8. Agent Deployment (Ready) 🚀

  • Local Deployment: Python script execution
  • Container Ready: Dockerfile-ready structure
  • Environment Configuration: ENV-based config
  • API Integration: Gemini API fully integrated
  • Cloud Deployment Scripts: Can be added for Cloud Run/Functions

Notes: Application is deployment-ready. Add Dockerfile and cloud configs as needed.

📊 Implementation Statistics

  • Total Files Created/Modified: 20+
  • Lines of Code: ~3000+
  • Test Coverage: 5 comprehensive tests
  • Agent Count: 4 (1 root + 3 sub-agents)
  • Custom Tools: 4
  • API Integration: Google Gemini 2.0
  • Architecture Pattern: Hub-and-Spoke
