# Conversation Persistence Implementation Summary
## ✅ Completed
### 1. ConversationHistoryManager (`src/orchestrator/ConversationHistoryManager.ts`)
**Full implementation of Option 4 (Embeddings + Retrieval):**
- ✅ Message storage with automatic embedding generation
- ✅ Vector similarity search for relevant past messages
- ✅ Session-based conversation management
- ✅ Smart context assembly (system + retrieved + recent + new)
- ✅ Neo4j vector index creation
- ✅ Session statistics and cleanup methods
**Key Methods:**
```typescript
// Store messages
await conversationHistory.storeMessage(sessionId, 'user', content);
await conversationHistory.storeConversationTurn(sessionId, userMsg, assistantMsg);
// Retrieve messages
await conversationHistory.getRecentMessages(sessionId, 10);
await conversationHistory.retrieveRelevantMessages(sessionId, query, 10, 0.70, 5);
// Build full context
await conversationHistory.buildConversationContext(sessionId, systemPrompt, query);
// Session management
await conversationHistory.getSessionStats(sessionId);
await conversationHistory.clearSession(sessionId);
```
### 2. CopilotAgentClient Integration (`src/orchestrator/llm-client.ts`)
**Integrated conversation history with LLM client:**
- ✅ Added imports for `ConversationHistoryManager` and `neo4j`
- ✅ Added private properties: `conversationHistory` and `neo4jDriver`
- ✅ Added `initializeConversationHistory()` method
- ✅ Updated `execute()` signature to accept optional `sessionId` parameter
- ✅ Updated `executeInternal()` to build conversation context before execution
- ✅ Added automatic conversation storage after successful execution
- ✅ Works for both direct LLM mode and agent mode
**Usage:**
```typescript
const agent = new CopilotAgentClient({
preamblePath: 'docs/agents/claudette-mimir-v2.md',
model: 'gpt-4',
temperature: 0.0
});
await agent.loadPreamble('docs/agents/claudette-mimir-v2.md');
await agent.initializeConversationHistory(); // Enable persistence
// Execute with session ID to enable persistence
const result = await agent.execute(
'Your task here',
0, // retryCount
undefined, // circuitBreakerLimit
'session-123' // sessionId enables persistence
);
```
### 3. Documentation
- ✅ `docs/guides/CONVERSATION_PERSISTENCE_GUIDE.md` - Complete usage guide
- ✅ This implementation summary document
### 4. Build Verification
- ✅ TypeScript compilation successful
- ✅ No linter errors
- ✅ All imports resolved
## Tool Registration Verification
### Tools Are Properly Configured ✅
**Checked:**
1. ✅ `webSearchTool` is defined in `src/orchestrator/tools.ts`
2. ✅ Included in `fileSystemTools` array
3. ✅ `consolidatedTools` includes all `fileSystemTools`
4. ✅ Agent class constructor uses `consolidatedTools` by default
5. ✅ Tools are passed to `createReactAgent()` correctly
6. ✅ Tools count is logged at initialization
**Tool List in consolidatedTools (14 tools):**
1. `run_terminal_cmd`
2. `read_file`
3. `write`
4. `search_replace`
5. `list_dir`
6. `grep`
7. `delete_file`
8. `web_search` ← **Available**
9. `memory_node` (MCP)
10. `memory_edge` (MCP)
11. `memory_batch` (MCP)
12. `get_task_context` (MCP)
13. `vector_search_nodes` (MCP)
14. `todo` (MCP)
### Added Debugging
Added debug logging to help diagnose tool calling issues:
```typescript
// Shows all tools registered with agent
console.log(`🔧 Agent initialized with ${this.tools.length} tools: ${this.tools.map(t => t.name).join(', ')}`);
// Shows if any tool calls were detected
console.log(`🔍 Debug: ${detectedToolCalls.length} tool calls detected in response`);
```
## Testing the Implementation
### Test Conversation Persistence
```typescript
// test-conversation-persistence.ts
import { CopilotAgentClient } from './src/orchestrator/llm-client.js';
async function testConversationPersistence() {
const agent = new CopilotAgentClient({
preamblePath: 'docs/agents/claudette-mimir-v2.md',
model: 'gpt-4',
temperature: 0.0
});
await agent.loadPreamble('docs/agents/claudette-mimir-v2.md');
await agent.initializeConversationHistory();
const sessionId = 'test-session-' + Date.now();
// First message
console.log('\n=== First Message ===');
const result1 = await agent.execute(
'I am building a React app with TypeScript and PostgreSQL',
0,
undefined,
sessionId
);
console.log('Response:', result1.output.substring(0, 200));
// Second message - should retrieve context from first
console.log('\n=== Second Message ===');
const result2 = await agent.execute(
'What database am I using?',
0,
undefined,
sessionId
);
console.log('Response:', result2.output);
// Check stats
const stats = await agent.conversationHistory.getSessionStats(sessionId);
console.log('\n=== Session Stats ===');
console.log(stats);
// Cleanup
await agent.conversationHistory.clearSession(sessionId);
}
testConversationPersistence().catch(console.error);
```
### Test Tool Calling
```typescript
// test-tool-calling.ts
import { CopilotAgentClient } from './src/orchestrator/llm-client.js';
async function testToolCalling() {
const agent = new CopilotAgentClient({
preamblePath: 'docs/agents/claudette-mimir-v2.md',
model: 'gpt-4', // Try different models
temperature: 0.0
});
await agent.loadPreamble('docs/agents/claudette-mimir-v2.md');
console.log('\n=== Testing Tool Calling ===');
const result = await agent.execute(
'Use the web_search tool to search for "LangGraph documentation"',
0
);
console.log('\nTool Calls:', result.toolCalls);
console.log('Output:', result.output.substring(0, 500));
}
testToolCalling().catch(console.error);
```
## Next Steps for Tool Calling Issue
The tool registration is **correct**. The issue is likely one of these:
### 1. Model Doesn't Support Function Calling Well
**Problem:** Some models (especially smaller ones) don't generate proper function calls.
**Check:**
```bash
# What model is being used?
grep -r "model:" llmconfig.json
```
**Solution:**
- Use a model known for good function calling: `gpt-4`, `gpt-3.5-turbo`, `claude-3-*`
- Avoid: TinyLlama, Phi, small Mistral variants
### 2. Model Is Generating Plans Instead of Actions
**Problem:** The agent is trained to "think before acting" and gets stuck in planning mode.
**Symptoms:**
- Outputs like "I'll start by...", "Sub-steps:", "Now searching..."
- No actual tool calls in the response
**Solution:**
Add to system prompt:
```markdown
**CRITICAL - IMMEDIATE TOOL EXECUTION:**
When you decide to use a tool, IMMEDIATELY invoke it. Do NOT announce what you will do.
NEVER write "I'll search..." or "Now I will..." - just invoke the tool directly.
WRONG: "I'll start by searching the web..."
RIGHT: [immediately calls web_search tool]
```
### 3. LangGraph Not Receiving Tool Definitions
**Check:**
Look at the debug output for:
```
🔧 Agent initialized with 14 tools: run_terminal_cmd, read_file, write, search_replace, list_dir, grep, delete_file, web_search, memory_node, memory_edge, memory_batch, get_task_context, vector_search_nodes, todo
🔍 Debug: 0 tool calls detected in response
```
If you see "0 tool calls" every time, the LLM isn't generating tool calls.
### 4. Tool Schema Issues
**Check:**
```typescript
// In src/orchestrator/tools.ts
console.log('web_search schema:', JSON.stringify(webSearchTool.schema, null, 2));
```
The schema should be valid JSON Schema format that LangChain can convert to function calling format.
## Recommended Debugging Steps
1. **Check Model:**
```bash
# In your pipeline
Check which model is actually being used
```
2. **Test with Known-Good Model:**
```typescript
// Use GPT-4 which definitely supports function calling
const agent = new CopilotAgentClient({
preamblePath: 'docs/agents/claudette-mimir-v2.md',
model: 'gpt-4',
provider: LLMProvider.COPILOT,
temperature: 0.0
});
```
3. **Add Explicit Tool Instruction:**
Modify system prompt to be more explicit about tool usage.
4. **Check Tool Call Format:**
Add logging to see what the LLM is actually generating:
```typescript
// After agent.invoke
console.log('Raw messages:', JSON.stringify(result.messages, null, 2));
```
## Environment Variables Needed
```bash
# For conversation persistence
NEO4J_URI=bolt://localhost:7687
NEO4J_USER=neo4j
NEO4J_PASSWORD=yourpassword
# For embeddings (if using Ollama)
# Configure in llmconfig.json:
{
"embeddings": {
"enabled": true,
"provider": "ollama",
"model": "nomic-embed-text",
"dimensions": 768,
"baseUrl": "http://localhost:11434"
}
}
```
## Summary
✅ **Conversation Persistence:** Fully implemented and integrated
✅ **Tool Registration:** Verified correct, tools are available
❓ **Tool Calling Issue:** Likely a model capability or prompting issue, not a code issue
The implementation is complete. The tool calling issue needs investigation at the **model/prompt level**, not the code level.
