# Phase 5 - Rich Help System Implementation

**Status:** ✅ Complete
**Date:** 2026-01-31
**Component:** CLI Application (`src/tracertm/cli/app.py`)

---

## Overview

Enhanced the TraceRTM CLI with a comprehensive Rich help system that provides beautiful, categorized, and informative help text for all commands. This implementation leverages Typer's Rich integration to create a superior command-line experience.

---

## Implementation Details

### 1. Pretty Exceptions Enabled

**File:** `src/tracertm/cli/app.py`

```python
app = typer.Typer(
    name="rtm",
    help="TraceRTM - Agent-native, multi-view requirements traceability system",
    add_completion=True,
    rich_markup_mode="rich",
    pretty_exceptions_enable=True,  # ✨ NEW
)
```

**Benefits:**
- Formatted exception tracebacks with syntax highlighting
- Clear error messages with context
- Better debugging experience for users and developers

---

```python
req_type: str = typer.Argument(
    ...,
    help="Requirement type ([cyan]epic[/cyan], [cyan]story[/cyan], [cyan]test[/cyan], etc.)"
)
```
