# Ggen CLI Command Pattern

Professional template for generating new ggen CLI commands with proper structure, testing, and documentation.

## Features

- ✅ Proper error handling with `Result<()>`
- ✅ Clap argument parsing
- ✅ Comprehensive test suite
- ✅ Documentation generation
- ✅ Production-ready code structure

## Usage

```bash
# Install from marketplace
ggen market add "ggen-cli-command-pattern"

# Generate a new command
ggen template generate ggen-cli-command-pattern \
  --command_name "market verify" \
  --module_name "market/verify" \
  --description "Verify marketplace package signatures"

# Generate a command with subcommands
ggen template generate ggen-cli-command-pattern \
  --command_name "lifecycle" \
  --module_name "lifecycle/mod" \
  --description "Project lifecycle management" \
  --has_subcommands true
```

## Generated Files

- `cli/src/cmds/{module_path}.rs` - Command implementation
- `tests/{module_name}_test.rs` - Integration tests
- `docs/commands/{command_name}.md` - Command documentation

## Examples

See `examples/` directory for sample generated commands.
