split-issue

What problem does it solve?

It turns an already-defined split plan into real GitHub child issues, keeping all related context in sync and making progress visible through issue linkages and labels.

Core Features & Use Cases

• Executes an approved split plan by reading the parent issue’s evaluation block and the chosen split strategy recorded by evaluate-issue.
• Creates and links child issues idempotently (reuses existing open issues when possible; otherwise creates missing ones and records the mapping).
• Slices the parent’s enriched spec into scoped scope-briefs so each child contains only the relevant Summary, ACs, files, and conventions.
• Wires parent ↔ children state by updating the parent’s split-children task list and writing a Created children mapping back into the evaluation block.
• Optionally auto-enriches children by running improve-issue sequentially on newly created issues.
• Supports two test-ownership strategies (parent-owned integrated tests vs sibling-owned integrated tests with a synthetic test child).

Quick Start

Run /skill split-issue with the parent issue number (or URL) that already contains a Chosen split plan from evaluate-issue.
