Key Improvements

1. Visual Design

Before (Original)

> user: check git status
[yellow]→ Executing: git status[/yellow]
STDOUT:
On branch main
...

AI: The status shows...

After (Modern)

❯ You
  check git status

╭─────────────────────────────────────────────────────────╮
│ Tool: bash                                              │
│   command: git status                                   │
╰─────────────────────────────────────────────────────────╯

╭─────────────────────────────────────────────────────────╮
│ ✓ bash                                                  │
│ On branch main                                          │
│ ...                                                     │
╰─────────────────────────────────────────────────────────╯

2. Workflow Changes

Before (Auto-Execute)

  1. User asks question
  2. AI responds with tool calls
  3. Tools execute automatically
  4. AI responds to results
  5. Repeat (up to 10 times)

After (Claude Code-like)

  1. User asks question
  2. AI responds with suggested tools
  3. User confirms tools (configurable)
  4. Tools execute
  5. AI responds to results

Ask Once (Default) Ask permission once per turn Interactive work
Ask Always Ask before each tool Learning, exploration
Auto Auto-execute safe tools Quick tasks
Manual Never auto-execute Maximum control

Installation & Usage

Install Both Versions

pip install -e .

This gives you two commands:

  1. deepcode or dc - Original (fast, auto-execute)
  2. deepcode-modern or dcm - New UI (clean, controlled)

Try the Modern Version

# Start modern interface
deepcode-modern

# Or use short alias
dcm

# With execution mode
dcm --mode once    # Ask before executing (default)
dcm --mode ask     # Ask for each tool
dcm --mode auto    # Auto-execute (like original)
dcm --mode manual  # Never auto-execute

◆ Assistant

I've reviewed your authentication system. Here's my analysis:

## Security Findings

1. ✓ Passwords properly hashed with bcrypt
2. ⚠ Sessions don't have expiration
3. ⚠ No rate limiting on login attempts

## Recommendations

[Detailed recommendations with code examples]

Migration Guide

From Original to Modern

No breaking changes! Both versions coexist:

# Continue using original
deepcode

# Try modern version
deepcode-modern

# Switch permanently
alias deepcode='deepcode-modern'

Configuration

Same .env file works for both:

DEEPSEEK_API_KEY=your_key
DEEPSEEK_MODEL=deepseek-chat

Troubleshooting

Issue: Modern UI not displaying correctly

Solution: Update Rich library

pip install --upgrade rich

Issue: Panels are broken/misaligned

Solution: Use a modern terminal

  • ✅ iTerm2 (macOS)
  • ✅ Windows Terminal (Windows)
  • ✅ GNOME Terminal (Linux)
  • ❌ Default Terminal.app (limited)

Issue: Colors not showing

Solution: Check terminal color support

echo $TERM  # Should be xterm-256color or similar
