Tips and Tricks for Productive AI Coding with Gemini CLI

After working with hundreds of developers using Gemini CLI, we've discovered powerful techniques that can dramatically boost your productivity. This collection of advanced tips, hidden features, and workflow optimizations will help you become a more effective AI-assisted developer.

Master-Level Prompting Techniques

1. Context Layering Strategy

Build context progressively for complex tasks:

# Layer 1: High-level context
gemini -p "I'm building a React e-commerce app with TypeScript and Redux"

# Layer 2: Specific context  
> "@src/store/ This is my Redux store structure"

# Layer 3: Focused request
> "Add shopping cart functionality with persistence and optimization"

2. Multi-File Context Combining

# Combine related files for holistic analysis
gemini -p "@src/components/ProductCard.tsx @src/hooks/useCart.ts @src/types/product.ts 
Review these related files and suggest improvements for type safety and performance"

3. Template-Driven Development

# Create reusable prompt templates
gemini -p "Generate a React component following this template:
- TypeScript with strict typing
- Styled with Tailwind CSS  
- Include error boundaries
- Add comprehensive PropTypes
- Include unit tests
- Follow accessibility guidelines

Component: ProductGrid with filtering capabilities"

Advanced File Operations

1. Smart Directory Analysis

# Analyze entire project structure
gemini -p "@. Provide an architectural overview and identify potential improvements"

# Focus on specific layers
gemini -p "@src/components/ @src/hooks/ Analyze component-hook relationships and suggest optimizations"

# Exclude noise
gemini -p "@src/ --exclude node_modules,dist,coverage Analyze source code only"

2. Progressive File Building

# Build complex files step by step
gemini -p "Create a user authentication service. Start with the interface definition."
> "Now add the implementation with JWT support"
> "Add error handling and logging"
> "Include unit tests"
> "Add integration tests"

3. Cross-File Consistency Checks

# Ensure consistency across related files
gemini -p "@src/types/ @src/api/ Check that API responses match TypeScript interfaces"
gemini -p "@src/components/ @src/styles/ Verify all components use consistent styling patterns"

Powerful Shell Integration

1. Command Chaining Workflows

# Test-driven development workflow
gemini -p "Write Jest tests for user authentication" && \
npm test -- --watch & \
gemini -p "Implement the authentication logic to pass these tests"

2. Git Integration Patterns

# Pre-commit review workflow
git add . && \
gemini -p "Review staged changes for potential issues before commit: $(git diff --cached)" && \
git commit -m "$(gemini -p 'Generate concise commit message for: $(git diff --cached --name-only)')"

3. Environment-Aware Commands

# Different prompts for different environments
if [ "$NODE_ENV" = "production" ]; then
  gemini -p "Review @src/ for production readiness and security"
else
  gemini -p "Suggest development workflow improvements for @src/"
fi

Sandbox Mode Mastery

1. Safe Experimentation

# Try risky operations safely
gemini -s -p "Experiment with different database schema migrations and test rollback procedures"

# Test performance optimizations
gemini -s -p "Benchmark different sorting algorithms with our data structure"

2. Isolated Testing

# Test external integrations safely
gemini -s -p "Simulate API failures and test our error handling strategies"

# Validate security measures
gemini -s -p "Attempt common security attacks against our authentication system"

3. Learning Through Experimentation

# Learn new technologies safely
gemini -s -p "Create a sample project using GraphQL with our existing REST API data"

# Prototype new features
gemini -s -p "Build a real-time chat feature prototype using WebSockets"

Advanced MCP Server Utilization

1. Custom Tool Combinations

# Combine multiple tools for comprehensive analysis
gemini -p "Use code analysis tools to review @src/, then use documentation generator to create updated docs"

# Chain tool operations
gemini -p "Use database tool to analyze schema, then use migration tool to suggest optimizations"

2. Workflow Automation

# Setup automated code review
gemini -p "Configure MCP tools for automated security scanning, performance analysis, and style checking"

# Create deployment pipelines  
gemini -p "Use deployment tools to create staging environment and run integration tests"

Hidden Features and Shortcuts

1. Configuration Optimization

// ~/.gemini/settings.json - Power user configuration
{
  "fileFiltering": {
    "respectGitIgnore": true,
    "maxFileSize": "2MB",
    "excludePatterns": ["*.log", "node_modules", ".git", "dist", "coverage"]
  },
  "prompting": {
    "autoContext": true,
    "smartSuggestions": true,
    "codeBlockFormatting": "enhanced"
  },
  "sandbox": {
    "autoCleanup": true,
    "resourceLimits": {
      "memory": "1GB",
      "timeout": "5m"
    }
  }
}

2. Keyboard Shortcuts & Aliases

# Create powerful aliases
alias gcode='gemini -p "Review and improve the current file: $(pwd)/$(ls -t | head -n1)"'
alias gtest='gemini -p "Generate tests for: @$(find . -name "*.js" -o -name "*.ts" | grep -v test | head -n1)"'
alias gfix='gemini -p "Fix linting errors in staged files: $(git diff --cached --name-only)"'

# Project-specific shortcuts
alias gapi='gemini -p "@src/api/ Review API endpoints for security and consistency"'
alias gcomp='gemini -p "@src/components/ Optimize React components for performance"'

3. Smart History Management

# Reuse successful prompts
gemini --history | grep "success" | tail -5  # Show last 5 successful prompts
gemini --replay-last                         # Rerun last command
gemini --bookmark "code review workflow"     # Bookmark successful patterns

Performance Optimization Techniques

1. Efficient Context Management

# Use focused context for better performance
gemini -p "@src/utils/specific-file.js Optimize this utility function" 
# Instead of: "@src/ Find and optimize utility functions"

# Batch related operations
gemini -p "@src/components/Header.tsx @src/components/Navigation.tsx @src/components/Footer.tsx 
Optimize these layout components together for consistency"

2. Memory Usage Optimization

# Process large codebases incrementally
for dir in src/components src/hooks src/utils; do
  gemini -p "@$dir/ Analyze and optimize this module"
done

# Use memory monitoring
gemini --show-memory-usage -p "Process large dataset analysis"

3. Response Time Improvements

# Use streaming for long responses
gemini --stream -p "Generate comprehensive documentation for @src/"

# Parallel processing for independent tasks
gemini -p "Review @src/auth.js for security" &
gemini -p "Optimize @src/database.js for performance" &
wait

Team Collaboration Patterns

gemini -p "@. Create an onboarding guide for new developers explaining our architecture, patterns, and conventions"

# Create project-specific tutorials
gemini -p "Generate step-by-step tutorials for common tasks in our codebase"

Debugging and Troubleshooting

1. Systematic Error Resolution

# Multi-step debugging workflow
gemini -p "Analyze this error: [paste error]
Context: @src/problematic-file.js
Steps: 1) Identify root cause 2) Suggest fixes 3) Provide tests to prevent recurrence"

2. Performance Profiling

# AI-assisted performance analysis
gemini -s -p "Profile the performance of @src/data-processor.js and suggest optimizations"
