What is issues-workflow?
Plan and track work using a GitHub Issues-first workflow with sub-issue hierarchies. Use whenever the user needs to organize issues into parent-child hierarchies, manage sub-issues, track research across multiple issues, or coordinate cross-repo issue workflows. Also use when the user asks about issue tracking strategy or how to structure work breakdown in GitHub. Do NOT use for creating individual issues (use issue-create instead) or for GitHub Projects board management. Source: terrylica/cc-skills.
