# 🔧 Fix: Orchestrator Now Finds Subagents

## Problem Identified

After implementing per-user agent isolation, the **Orchestrator agent** was not delegating tasks to subagents. Instead, it would plan to invoke subagents but then provide a generic clinical recommendation without actually calling them.

### Example Behavior (Broken):
```
User: "how to treat a 65 YO F w/ c.diff..."
Orchestrator: "🎯 Enhanced Execution Plan..."
User: "proceed"
Orchestrator: "🚀 Executing plan...🎯 Comprehensive Clinical Recommendation..."
  (Generic response, no subagent invocation)
```

### Root Cause

The `OrchestratorAgent` was being initialized with an **empty agents configuration** because it was trying to access the **global** `agents_config` dictionary:

```python
# OLD (Broken):
# In chat_orchestrator.py line 244:
runtime_agents_config = getattr(app_module, 'agents_config', {})  # ❌ Global = empty
orch = OrchestratorAgent(runtime_agents_config, api_key)  # No subagents available!
```

Since all agents are now stored **per-user** in session storage, the global dictionary was empty, so the orchestrator thought there were no subagents to delegate to.

---

## Solution Applied

### 1. Updated `simulate_agent_response_stream` Function

Added a `user_agents_config` parameter to pass the user's agent configurations:

```python
# chat_orchestrator.py
async def simulate_agent_response_stream(
    agent_json, 
    history, 
    user_input, 
    debug_flag, 
    active_children, 
    user_agents_config=None  # ✅ NEW parameter
):
    """
    Args:
        user_agents_config: Dict of user's agent configurations (for orchestrator subagents)
    """
```

### 2. Updated Orchestrator Initialization Logic

Modified the orchestrator creation to use the per-user config:

```python
# OLD (Broken):
if 'app' in sys.modules:
    app_module = sys.modules['app']
    runtime_agents_config = getattr(app_module, 'agents_config', {})  # ❌ Empty
else:
    from config import agents_config as runtime_agents_config

# NEW (Fixed):
if user_agents_config is not None:
    runtime_agents_config = user_agents_config  # ✅ Use user's agents
else:
    # Fallback to global (legacy)
    import sys
    if 'app' in sys.modules:
        app_module = sys.modules['app']
        runtime_agents_config = getattr(app_module, 'agents_config', {})
    else:
        from config import agents_config as runtime_agents_config

orch = OrchestratorAgent(runtime_agents_config, api_key)  # ✅ Now has subagents!
```

### 3. Updated All Function Calls in app.py

Updated **3 locations** where `simulate_agent_response_stream` is called to pass the user's agents:

#### Location 1: `chatpanel_handle()` (Deployed Chat Panel)
```python
async def run_stream():
    # Get user's agents config for orchestrator subagents
    user_agents_cfg = get_user_agents_config(request)  # ✅ NEW
    async for updated_history, _, invocation_log, _, challenger_info in simulate_agent_response_stream(
        agent_json=agent_json,
        history=history,
        user_input=user_text,
        debug_flag=False,
        active_children=[],
        user_agents_config=user_agents_cfg  # ✅ PASS user's agents
    ):
        yield updated_history, invocation_log
```

#### Location 2: `builderpanel_handle_with_dynamic_vars()` (Builder Panel)
```python
async def run_stream():
    # Get user's agents config for orchestrator subagents
    user_agents_cfg = get_user_agents_config(request)  # ✅ NEW
    gen = simulate_agent_response_stream(
        agent_json=agent_json_val,
        history=history_val,
        user_input=user_text,
        debug_flag=False,
        active_children=[],
        user_agents_config=user_agents_cfg  # ✅ PASS user's agents
    )
```

#### Location 3: `chatpanel_handle_with_dynamic_vars()` (Deployed Chat with Dynamic Fields)
```python
async def run_stream():
    final_history = history_val
    final_invocation_log = ""
    challenger_info = None
    
    # Get user's agents config for orchestrator subagents
    user_agents_cfg = get_user_agents_config(request)  # ✅ NEW
    gen = simulate_agent_response_stream(
        agent_json=agent_json_val,
        history=history_val,
        user_input=user_text,
        debug_flag=False,
        active_children=[],
        user_agents_config=user_agents_cfg  # ✅ PASS user's agents
    )
```

## How It Works Now

### Expected Behavior (Fixed):

1. **User creates orchestrator + subagents:**
   - Orchestrator agent: "ID Maestro"
   - Subagent 1: "Stewardship Expert"
   - Subagent 2: "Infectious Disease Specialist"
   - All stored in user's session

2. **User chats with orchestrator:**
   ```
   User: "how to treat a 65 YO F w/ c.diff..."
   Orchestrator: "🎯 Enhanced Execution Plan..."
     - Will invoke: "Stewardship Expert"
     - Will invoke: "Infectious Disease Specialist"
   User: "proceed"
   Orchestrator: "🚀 Executing plan..."
     ✅ Calls "Stewardship Expert" → Gets response
     ✅ Calls "Infectious Disease Specialist" → Gets response
     ✅ Synthesizes responses into comprehensive recommendation
   ```

3. **Orchestrator now has access to:**
   - ✅ All user's subagents
   - ✅ Can delegate tasks properly
   - ✅ Can synthesize multi-agent responses

---

## Multi-User Isolation Preserved

### User A's Workspace:
```
User A's Agents:
  - Orchestrator: "ID Maestro A"
  - Subagent: "Stewardship Expert A"
  - Subagent: "ID Specialist A"

When User A's orchestrator runs:
  ✅ Sees only User A's subagents
  ✅ Can delegate to "Stewardship Expert A" and "ID Specialist A"
```

### User B's Workspace:
```
User B's Agents:
  - Orchestrator: "ID Maestro B"
  - Subagent: "Cardiology Expert B"
  - Subagent: "Pharmacy Expert B"

When User B's orchestrator runs:
  ✅ Sees only User B's subagents
  ✅ Can delegate to "Cardiology Expert B" and "Pharmacy Expert B"
```

**No cross-contamination!** Each orchestrator only sees and uses its user's subagents.

---

## Testing

### Quick Test:

1. **Build subagents first:**
   - Create a specialist agent (e.g., "Stewardship Expert")
   - Create another specialist (e.g., "ID Consultant")

2. **Build orchestrator:**
   - Create orchestrator agent type
   - Name it (e.g., "ID Maestro")

3. **Chat with orchestrator:**
   ```
   You: "Patient with complicated UTI, what antibiotics?"
   Orchestrator: Creates execution plan
   You: "proceed"
   Orchestrator: ✅ Should invoke your subagents and synthesize their responses
   ```

4. **Verify:**
   - ✅ See "Invoking [SubagentName]" in execution log
   - ✅ See subagent-specific responses
   - ✅ See synthesized final recommendation
