CLI application builder plugin with comprehensive patterns for argument parsing, configuration, interactive prompts, and output formatting
Standard library Python argparse examples with subparsers, choices, actions, and nested command patterns. Use when building Python CLIs without external dependencies, implementing argument parsing, creating subcommands, or when user mentions argparse, standard library CLI, subparsers, argument validation, or nested commands.
Modern type-safe Rust CLI patterns with Clap derive macros, Parser trait, Subcommand enums, validation, and value parsers. Use when building CLI applications, creating Clap commands, implementing type-safe Rust CLIs, or when user mentions Clap, CLI patterns, Rust command-line, derive macros, Parser trait, Subcommands, or command-line interfaces.
Lightweight Go CLI patterns using urfave/cli. Use when building CLI tools, creating commands with flags, implementing subcommands, adding before/after hooks, organizing command categories, or when user mentions Go CLI, urfave/cli, cobra alternatives, CLI flags, CLI categories.
CLI testing strategies and patterns for Node.js (Jest) and Python (pytest, Click.testing.CliRunner). Use when writing tests for CLI tools, testing command execution, validating exit codes, testing output, implementing CLI test suites, or when user mentions CLI testing, Jest CLI tests, pytest CLI, Click.testing.CliRunner, command testing, or exit code validation.
Click framework examples and templates - decorators, nested commands, parameter validation. Use when building Python CLI with Click, implementing command groups, adding CLI options/arguments, validating CLI parameters, creating nested subcommands, or when user mentions Click framework, @click decorators, command-line interface.
Production-ready Cobra CLI patterns including command structure, flags (local and persistent), nested commands, PreRun/PostRun hooks, argument validation, and initialization patterns used by kubectl and hugo. Use when building Go CLIs, implementing Cobra commands, creating nested command structures, managing flags, validating arguments, or when user mentions Cobra, CLI development, command-line tools, kubectl patterns, or Go CLI frameworks.
Auto-generated CLI patterns using Google Fire with class-based structure, docstring parsing, and nested classes. Use when building Python CLI applications, creating Fire CLIs, implementing auto-generated commands, designing class-based CLIs, or when user mentions Fire, Google Fire, CLI generation, docstring commands, nested command groups, or Python command-line tools.
Interactive prompt patterns for CLI tools with text, list, checkbox, password, autocomplete, and conditional questions. Use when building CLIs with user input, creating interactive prompts, implementing questionnaires, or when user mentions inquirer, prompts, interactive input, CLI questions, user prompts.
Enterprise CLI patterns using oclif framework with TypeScript. Use when building oclif CLIs, creating plugins, implementing commands with flags/args, adding auto-documentation, testing CLI commands, or when user mentions oclif, enterprise CLI, TypeScript CLI, plugin system, or CLI testing.
Modern type-safe Typer CLI patterns with type hints, Enums, and sub-apps. Use when building CLI applications, creating Typer commands, implementing type-safe CLIs, or when user mentions Typer, CLI patterns, type hints, Enums, sub-apps, or command-line interfaces.
