## Tips for Creating Effective Agents

1. **Clear Subscribe/Publish Topics**: Use descriptive names like "SQL_GENERATED" not just "STEP2"

2. **Prompt Placeholders**: 
   - Use `{question}` for the user's input question
   - Use `{input}` for the message from the subscribed topic
   - Use `{schema}` to access the database schema
   - All three can be used together in any prompt

3. **Model Selection**:
   - **phi4-mini**: Versatile general-purpose model - text analysis, SQL, reasoning, classification
   - **cniongolo/biomistral**: Medical and scientific tasks - diagnosis, clinical reasoning, biomedical analysis

4. **Final Results**:
   - Publish to topic "FINAL" to display results in the Final Result box
   - Only the last agent in your chain should publish to FINAL

4. **Chain Design**:
   - Start simple with 2-3 agents
   - Each agent should have ONE clear purpose
   - Test each agent individually first

5. **Error Handling**:
   - If an agent has no subscribers for its publish topic, the chain stops
   - Make sure START has at least one subscriber
   - Check that all topics form a connected chain

6. **Debugging**:
   - Watch the execution log carefully
   - Check which topics have subscribers
   - Verify message flow through the bus
