What specific tools does this skill check for?

The skill currently validates the presence of the GitHub CLI (gh), the jq JSON processor, and Git within your system's PATH.

How does the 'fail-fast' mechanism work?

If any prerequisite is missing, the skill immediately exits with code 1 and displays a clear error message, stopping the current workflow before it encounters more complex errors.

Does it check if I am logged into GitHub?

Yes, it runs 'gh auth status' to ensure that your GitHub CLI is authenticated, preventing permission errors during git operations.

Can I use this skill as a setup guide?

Absolutely. If your environment is not ready, the skill provides specific URLs and commands (like brew or apt-get) to help you install the necessary tools.

開発者ツール

Verifies that essential system dependencies, GitHub CLI authentication, and development tools are correctly configured before executing workflows.

The Dev Environment Validator acts as a critical pre-flight check (Phase -1) for automated developer workflows within Claude Code. It ensures that essential tools such as the GitHub CLI (gh), jq, and Git are not only installed but also properly authenticated and accessible. By adopting a 'fail-fast' approach, this skill prevents complex automation tasks from failing mid-process due to missing environment requirements. When a dependency is missing, it provides clear, actionable feedback including installation links and terminal commands to rectify the issue immediately.
