For AI-powered commit messages, you'll need API keys:

# OpenAI (for GPT-5, GPT-4.1 models) export OPENAI_API_KEY="your-openai-api-key" # Anthropic Claude (for Claude 4.5, Claude 4.1 models) export ANTHROPIC_API_KEY="your-anthropic-api-key" # Google Gemini (for Gemini 2.5 models) export GOOGLE_API_KEY="your-google-api-key" # Local AI (via Ollama - requires installation) # No API key needed, runs locally

# Redate commits within a specific date range gctm redate --start "2023-01-01" --end "2023-01-30" # Include backup gctm redate --start "2023-01-01" --end "2023-01-30" --backup # Interactive mode gctm redate --interactive

# Edit a specific commit message gctm edit-message --commit "a1b2c3d" --message "New commit message" # Interactive mode gctm edit-message --interactive

# Replace a specific pattern gctm edit-content --commit "a1b2c3d" --pattern "API_KEY" --replacement "***HIDDEN***" # Interactive mode gctm edit-content --interactive

# Clean sensitive data gctm sanitize --patterns "email,apiKeys" --replacement "***REDACTED***" # Interactive mode gctm sanitize --interactive

# Create backup gctm backup create --description "Pre-operation backup" # List backups gctm backup list # Restore backup gctm backup restore <backupId> # Delete backup gctm backup delete <backupId>

# Generate AI commit messages (requires API key) export OPENAI_API_KEY="your-openai-api-key" # Basic AI generation gctm ai-generate # Generate in Turkish with humorous style gctm ai-generate --language tr --style humorous # Interactive selection and application gctm ai-generate --interactive # Generate with additional context gctm ai-generate --context "Fixed critical authentication bug" # Improve existing commit message gctm ai-generate --current-message "fix bug" --style descriptive
