Gemini Chat

Gemini Interactive Chat

Advanced interactive chat workflows with Gemini CLI, featuring context management, multimodal support, and session persistence.

Quick Start

# Start interactive chat
gemini -i "Let's work on my project"

# Start with specific context
gemini --include-directories ./src -i "Help me refactor this code"

# Start with checkpointing and YOLO mode (toggle in session)
gemini --checkpointing -i "Complex multi-step task"

YOLO Mode in Interactive Sessions

YOLO mode can be toggled during interactive sessions for automated execution:

# In interactive mode:
# Ctrl+Y              # Toggle YOLO mode on/off
# /yolo on            # Enable auto-approval
# /yolo off           # Disable auto-approval

# Start with YOLO already enabled (for automation)
gemini --yolo -i "Set up complete development environment automatically"

# Mixed mode workflow
gemini -i "Let's plan first, then execute with YOLO"
# Plan manually, then: Ctrl+Y to enable YOLO for execution

When to use YOLO in chat:

• ✅ File operations (create, edit, organize)
• ✅ Batch processing tasks
• ✅ Project setup and configuration
• ✅ Documentation generation
• ❌ Complex system changes (review first)
• ❌ Unknown/experimental commands

Interactive Commands

Please help me:
    1. Generate creative ideas
    2. Evaluate feasibility
    3. Identify challenges
    4. Suggest next steps"
  
  # Save final summary with YOLO
  gemini --yolo -p "Summarize our brainstorming session and create actionable next steps" \
    > ~/.gemini/sessions/$session_name/summary.md
  
  echo "Session saved to ~/.gemini/sessions/$session_name/"
}

# Automated brainstorming with YOLO

#!/bin/bash
# Save and resume sessions

# Save session
save_session() {
  local name="${1:-session}"
  gemini checkpoint save "$name"
  echo "Session saved as: $name"
}

# List sessions
list_sessions() {
  gemini checkpoint list
}

# Resume session
resume_session() {
  local name="$1"
  gemini checkpoint restore "$name"
  gemini -i "Let's continue where we left off"
}

# Delete old sessions
cleanup_sessions() {
  local days_old="${1:-7}"
  find ~/.gemini/checkpoints -mtime +$days_old -delete
  echo "Cleaned up sessions older than $days_old days"
}

Multi-Modal Conversations

#!/bin/bash
# Work with images and text

analyze_designs() {
  local design_dir="$1"
  
  gemini -i "Let's review UI designs"
  
  # In the chat:
  # @./designs/homepage.png

  # "Compare these designs and suggest improvements"
}

# Screenshot analysis
analyze_screenshot() {
  # Take screenshot (macOS)
  screencapture -i /tmp/screenshot.png
  
  # Or Linux

  # Monitor context size
  while true; do
    context_size=$(gemini context size)
    
    if [ $context_size -gt $max_context ]; then
      echo "Context limit approaching. Compressing..."
      gemini /compress
    fi
    
    # Continue chat

}

Integration Patterns

Vim Integration

" .vimrc
" Send selection to Gemini
vnoremap <leader>g :w !gemini -p "Explain this code: $(cat)"<CR>

" Get suggestions
nnoremap <leader>G :r !gemini -p "Improve this function: $(cat %:p)"<CR>

" Interactive help
nnoremap <leader>? :terminal gemini -i "Help with vim and %:t"<CR>

VS Code Integration

# Connect Gemini to VS Code
gemini /ide install
gemini /ide enable

# Now Gemini can see your VS Code context
gemini -i "Help me with the file I have open in VS Code"

Tmux Workflow

#!/bin/bash
# Split-screen coding with Gemini

gemini_tmux() {
  tmux new-session -d -s gemini-coding
  
  # Main coding pane
  tmux send-keys -t gemini-coding "vim" C-m
  
  # Gemini chat pane
  tmux split-window -h -t gemini-coding
  tmux send-keys -t gemini-coding "gemini -i 'Help me code'" C-m
  
  # File tree pane
  tmux split-window -v -t gemini-coding
  tmux send-keys -t gemini-coding "watch -n 2 'tree -L 2'" C-m
  
  # Attach to session
  tmux attach -t gemini-coding
}

Best Practices

Effective Prompting

1. Be Specific

   # Bad
   "Help me with code"
   
   # Good
   "Help me refactor this authentication module to use JWT tokens"
   

2. Provide Context

   # Include relevant files
   gemini --include-directories ./src/auth,./tests/auth
   

3. Set Constraints

   "Explain in simple terms, with examples, max 100 lines"
   

Session Hygiene

1. Regular Compression

   # Compress every 30 minutes
   /compress
   

2. Save Important Sessions

   /checkpoint
   

3. Clear Irrelevant Context

   /clear context
   

Troubleshooting

Common Issues

1. Slow Responses

   • Compress context: /compress
   • Use faster model: gemini -m gemini-2.5-flash
   • Reduce included directories

2. Lost Context

   • Check checkpoints: /restore
   • Review history: ~/.gemini/history

3. Tool Errors

   • Check available tools: /tools
   • Verify permissions: ls -la
