What problem does it solve? Teams struggle to answer "what will be done by when?" when issues pile up without time-based grouping. This Skill organizes GitHub issues and epics into milestones with due dates, progress tracking, and slippage handling so delivery commitments stay visible. ## Core Features & Use Cases - Milestone Creation & Naming: Create milestones via the GitHub CLI with conventions for versions, quarters, phases, and sprints, plus a structured description template covering goals, deliverables, and success criteria. - Issue & Epic Assignment: Assign individual issues or bulk-assign all issues in an epic to a milestone using gh commands. - Progress Tracking & Reports: Query milestone open/closed counts, compute completion percentages, and generate weekly status reports with on-track/at-risk indicators. - Slippage Handling: Move issues to the next milestone, extend due dates, or reduce scope, and document the changes as comments. - Use Case: A team planning a v2.0.0 release creates a milestone with a due date, assigns three epics and their issues, then generates a weekly progress report showing 60% completion with blockers flagged. ## Quick Start Ask the AI to create a GitHub milestone named v1.0.0 with a due date, assign your open issues to it, and show a progress report.
