SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Command-line interfaces are often hard to use, error-prone, and unsafe; this skill provides a structured framework to design, review, and refine CLIs for usability, safety, and automation.

Core Features & Use Cases

  • Clear command models and consistent flag semantics across languages.
  • Strong emphasis on non-interactive paths, secrets safety, and robust help and documentation.
  • Use cases include building new CLIs, auditing existing ones, and aligning with Open Agent Skills standards.

Quick Start

Draft a minimal CLI design by outlining a single command with its core flags and a concise help example.

FAQPage Schema
How do I design a command-line interface for both interactive and CI environments?

To design a command-line interface for these environments, establish predictable exit codes, ensure non-interactive paths, and define TTY behavior. This approach guarantees your CLI operates safely and consistently across automated pipelines and user terminals.

What is the best way to handle secrets and flags in CLI design?

Handling secrets and flags in CLI design requires implementing strict secrets safety guidelines and consistent flag semantics. Validating your command model against these rules prevents accidental exposure and ensures predictable argument parsing.

How do I write help text and usage docs for a command-line tool?

Writing help text and usage docs for a command-line tool involves crafting a consistent command model with concise examples. Applying structured CLI design guidelines ensures your documentation is clear, robust, and helpful for users.

How do I audit an existing CLI for usability and safety issues?

Auditing an existing CLI for usability and safety involves validating its design against structured guidelines for non-interactive paths, secrets safety, and exit codes. This review identifies inconsistencies in error handling and TTY behavior.

Why does my command-line tool fail in non-interactive automation pipelines?

Command-line tools fail in non-interactive pipelines when they lack predictable exit codes or attempt interactive prompts. Designing your CLI with explicit non-interactive paths and TTY behavior checks resolves these automation errors.
