What problem does it solve? Coordinating the implementation of a large GitHub epic across many child issues is error-prone: branches get tangled, PRs lose traceability to issues, and CI failures cascade. This Skill automates the entire flow by turning each child issue into one stacked PR using gh stack, with an orchestrator agent per child. ## Core Features & Use Cases - Stacked PR Generation: Creates one PR per child issue on a gh stack branch chain, keeping each PR independently mergeable. - Per-Child Orchestration: Spawns a fresh orchestrator agent per child that runs create-implementation-plan, implement-plan-and-open-pr, and post-PR review subagents. - CI Gating and Traceability: Waits for GitHub checks after each PR, stops on failures, and links every PR with "Fixes #child" and "Part of #parent". - Final Cross-Stack Review: Runs a simplification and consistency review pass across the whole stack and opens a revision PR if needed. - Use Case: You have a parent issue with five filed child issues from create-epic. Run /implement-epic to get five stacked, CI-verified PRs plus a summary table, without writing orchestration logic yourself. ## Quick Start Run /implement-epic with the URL of a parent GitHub issue that already has child issues filed, then approve the proposed branch plan.
