Why use this instead of checking manually?

It automates the verification process, ensuring that complex multi-step workflows never fail halfway through due to a missing system binary or expired login.

Does this skill support automated fixes?

No, it follows a fail-fast manual-fix approach to ensure the user is aware of their environment state and to maintain security regarding CLI authentication.

What happens if a dependency is missing?

The skill will provide a clear error message, offer installation instructions or links, and exit with code 1 to stop the workflow immediately.

Is this skill compatible with all operating systems?

This skill uses Bash-based commands, making it ideal for macOS, Linux, and Windows environments using WSL or Git Bash.

What specific tools does this skill verify?

The skill checks for the GitHub CLI (gh), the jq JSON processor, and git. It also checks if the GitHub CLI is currently authenticated.

デプロイメントとDevOps

Verifies essential system dependencies and CLI tools before initiating automated development workflows to ensure environment readiness.

The System Prerequisite Checker is an orchestration utility designed to validate your environment before executing complex automated tasks. It performs high-speed checks for critical tools including the GitHub CLI (gh), jq, and git, ensuring they are not only installed but also properly authenticated. By implementing a fail-fast strategy, it prevents mid-workflow errors and provides developers with clear, actionable installation instructions for any missing components, making it an essential first step for any automated script or CI/CD pipeline.
