# cli Plugin

CLI platform discipline: command-line interface design, shell scripting conventions, and terminal UX patterns.

## Skills

- | Skill | Purpose |

- | ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |

- | `cli` | CLI application design: argument conventions, output streams, exit codes, configuration hierarchy, interactive modes, signal handling, and terminal UX |

- | `shell-scripting` | Shell script conventions and defensive patterns: strict mode, quoting, portability, error handling, and common pitfalls |

+ - **`cli`** — CLI application design: argument conventions, output streams, exit codes, configuration hierarchy,

+ interactive modes, signal handling, and terminal UX

+ - **`shell-scripting`** — shell script conventions and defensive patterns: strict mode, quoting, portability, error

+ handling, and common pitfalls

## Skill Dependencies

The two skills are complementary but independent. `cli` covers the interface between a program and the

terminal/shell/pipeline — it applies regardless of implementation language. `shell-scripting` covers shell-specific

correctness when the implementation language IS shell (bash, sh, zsh).

Both skills assume `the-coder` for language-agnostic coding discipline (discovery, planning, verification).

Language-specific concerns (Go's cobra, Node's commander) come from their respective language plugins.

## Plugin Scope

This plugin covers CLI platform concerns specific to building command-line tools and terminal applications. It provides

two layers:

- **Design layer** (`cli`) — how a CLI should behave: argument conventions, output streams, exit codes, signal handling.

Applies to CLIs written in any language.

- **Implementation layer** (`shell-scripting`) — how to write correct shell scripts: strict mode, quoting, error

handling, portability. Applies only to shell scripts.

Language-specific implementations (argument parsing libraries, terminal I/O APIs) are provided by their respective

language plugins.
