Quick Reference

For detailed API reference:

• Conversations & Testing: See references/conversations.md

Scripts

• scripts/conversations.py — CLI wrapper for conversation operations

Usage

python scripts/conversations.py detect-intent --agent AGENT_NAME --text "Hello"
python scripts/conversations.py match-intent --agent AGENT_NAME --text "Hello"

Tips

• Session IDs can be any unique string (e.g., UUID)
• Use detectIntent for full conversation flow, matchIntent for testing without state changes
• Test cases help validate conversation logic before deployment
