Xantham Spec Kit Bridge

Category: Engineering · Sub-category: code-quality · Last updated: 2026-05-21

Use BEFORE dispatching @kai on a greenfield build (no existing code) with estimated budget >4 hours. Walks GitHub spec-kit's constitution -> spec -> plan -> tasks -> analyze pipeline first, so kai gets file-based artifacts with cross-artifact consistency checks rather than a fuzzy brief. Skip for bug fixes, ops work, refactors, brownfield modifications, or any task under 4 hours of estimated work. Pinned to spec-kit v0.8.8.dev0.

From the source SKILL.md

This skill turns a Xantham brief into spec-kit artifacts before kai dispatch.
