### Prompt System (Updated 2025-11-24)
The application uses a prompt system to manage various LLM prompts:

- **System Prompt**: `prompts/system_prompt.md` - Default system prompt prepended to all conversations
- Configurable via `system_prompt_filename` in AppSettings (default: `system_prompt.md`)
- Supports `{user_email}` template variable
- Can be overridden by MCP-provided prompts
- Loaded by `PromptProvider.get_system_prompt()`
- Automatically injected by `MessageBuilder` at conversation start

- `prompts/agent_reason_prompt.md` - Reasoning phase
- `prompts/agent_observe_prompt.md` - Observation phase

- **Tool Synthesis**: `prompts/tool_synthesis_prompt.md` - Tool selection guidance

All prompts are loaded from the directory specified by `prompt_base_path` (default: `prompts/`). The system caches loaded prompts for performance.

# Implementation Complete: Rate Limiting & Backend Error Reporting

## ✅ Task Completed Successfully

All backend errors (including rate limiting) are now properly reported to users with helpful, actionable messages.

---

## What Was Changed

### 1. Error Classification System
Created a comprehensive error detection and classification system that:
- Detects rate limit errors (Cerebras, OpenAI, etc.)
- Detects timeout errors
- Detects authentication failures
- Handles generic LLM errors

### 2. User-Friendly Error Messages
Users now see helpful messages instead of silence:

| Situation | User Sees |
|-----------|-----------|
| Rate limit hit | "The AI service is experiencing high traffic. Please try again in a moment." |
| Request timeout | "The AI service request timed out. Please try again." |
| Auth failure | "There was an authentication issue with the AI service. Please contact your administrator." |
| Other errors | "The AI service encountered an error. Please try again or contact support if the issue persists." |

### 3. Security & Privacy
- ✅ No sensitive information (API keys, internal errors) exposed to users
- ✅ Full error details still logged for debugging
- ✅ CodeQL security scan: 0 vulnerabilities

---

## Files Modified (8 files, 501 lines)

### Backend Core
- `backend/domain/errors.py` - New error types
- `backend/application/chat/utilities/error_utils.py` - Error classification logic
- `backend/main.py` - Enhanced WebSocket error handling

### Tests (All Passing ✅)
- `backend/tests/test_error_classification.py` - 9 unit tests
- `backend/tests/test_error_flow_integration.py` - 4 integration tests

### Documentation
- `docs/error_handling_improvements.md` - Complete guide
- `docs/error_flow_diagram.md` - Visual flow diagram
- `scripts/demo_error_handling.py` - Interactive demonstration

---

## How to Test

### 1. Run Automated Tests
```bash
cd backend
export PYTHONPATH=/path/to/atlas-ui-3/backend
python -m pytest tests/test_error_classification.py tests/test_error_flow_integration.py -v
```
**Result**: 13/13 tests passing ✅

### 2. View Demonstration
```bash
python scripts/demo_error_handling.py
```
Shows examples of all error types and their user-friendly messages.

### 3. Manual Testing (Optional)
To see the error handling in action:
1. Start the backend server
2. Configure an invalid API key or trigger a rate limit
3. Send a message through the UI
4. Observe the error message displayed to the user

---

## Before & After Example

### Before (The Problem)
```
User: *Sends a message*
Backend: *Hits Cerebras rate limit*
UI: *Sits there thinking... forever*
Backend Logs: "litellm.RateLimitError: We're experiencing high traffic..."
User: 🤷 "Is it broken? Should I refresh? Wait?"
```

### After (The Solution)
```
User: *Sends a message*
Backend: *Hits Cerebras rate limit*

## What Happens Now

The error classification system is now active and will:
- Automatically detect and classify backend errors
- Send user-friendly messages to the frontend
- Log detailed error information for debugging
- Work for any LLM provider (Cerebras, OpenAI, Anthropic, etc.)

No further action needed - the system is ready to use!
