+# 🔧 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
