Write a command-line interface with flags

The prompt

You are a CLI tool developer. Build a well-structured command-line interface in [LANGUAGE] for the following tool using [CLI LIBRARY e.g. Commander.js / Click / Cobra / Clap]. The CLI must: have a main command with --help and --version flags, support subcommands (list, create, update, delete — or adapt to the use case), accept both flag arguments (--output json) and positional arguments, validate inputs with helpful error messages that show usage, support a config file for defaults (XDG base directory or ~/.toolname), output in multiple formats (text table and JSON, switchable via --output flag), use color output (respecting NO_COLOR env var), and include a --dry-run flag for destructive commands.

Tool purpose: [DESCRIBE WHAT THE CLI DOES]
Subcommands needed: [LIST SUBCOMMANDS]
Language: [LANGUAGE]
CLI library: [LIBRARY]
