Skill: issue-implementation-train
Author: gorira-tatsu
Description: Implement an explicit set of GitHub issues end-to-end for this repository, using isolated worktrees, one branch per issue, targeted tests, pushes, and pull requests against `stg`. Use this when the user asks to implement specific issues, execute a planned batch of roadmap issues, or drive issue work through PR-ready completion. This skill is repo-specific: it never defaults to all open issues, requires an explicit issue set, and stops after initial PR creation rather than handling review follow-up.
