feat(agent): implement 3-layer architecture for better response quality
Implement a three-layer architecture to improve AI response quality:
Layer 1 - Intent Classifier (intent-classifier.ts):
- Classifies user intent into 6 types: SIMPLE_QUERY, DEEP_CONSULTATION,
ACTION_NEEDED, CHAT, CLARIFICATION, CONFIRMATION
- Determines suggested response length based on intent type
- Detects follow-up questions and extracts entities (visa types, etc.)
- Uses keyword matching for fast classification (no API calls)
Layer 2 - ReAct Agent (system-prompt.ts):
- Adds ReAct thinking framework to system prompt
- 4-step process: Understand -> Evaluate -> Act -> Generate
- Emphasizes concise responses, avoids redundant phrases
- Injects intent classification results to guide response strategy
Layer 3 - Response Gate (response-gate.ts):
- Quality checks: length, relevance, redundancy, completeness, tone
- Logs gate results for analysis and future optimization
- Can trim responses and remove redundant expressions
Integration (claude-agent.service.ts):
- Integrates all 3 layers in sendMessage flow
- Dynamically adjusts max_tokens based on intent type
- Collects full response for gate analysis
Documentation:
- Added AGENT_THREE_LAYER_ARCHITECTURE.md with detailed design docs
