23 Short: "Terminal-based AI assistant for software development",
24 Long: `Crush is a powerful terminal-based AI assistant that helps with software development tasks.
25It provides an interactive chat interface with AI capabilities, code analysis, and LSP integration
26to assist developers in writing, debugging, and understanding code directly from the terminal.`,
27 Example: `
28 # Run in interactive mode
29 crush
31 # Run with debug logging
32 crush -d
34 # Run with debug slog.in a specific directory
35 crush -d -c /path/to/project
37 # Print version
38 crush -v
40 # Run a single non-interactive prompt
41 crush -p "Explain the use of context in Go"
43 # Run a single non-interactive prompt with JSON output format
44 crush -p "Explain the use of context in Go" -f json
46 # Run in dangerous mode (auto-accept all permissions)
47 crush -y
