description	Shared prerequisite checks for repository skills. Used by other skills before running GitHub CLI workflows.

Repository Skill Preflight

Run these checks before the calling skill performs any other steps.

Checks

1. GitHub CLI — verify gh is installed
2. Authentication — verify the current gh authentication
3. Repository — resolve the repository from the current checkout

Stop at the first failed check and report its remediation. Continue with the calling skill only after every check succeeds.

Extension Rule

Add future checks here only when they apply broadly to repository skills. Keep task-specific input validation in the skill that owns the task.
