Prepare A PR For NeMo Fabric

Companion Guidance

Use karpathy-guidelines alongside this skill for implementation or review work. Keep changes scoped, surface assumptions, and define focused validation before editing.

Use this skill at the end of a contributor or maintainer change before opening a pull request. Also use it whenever a user asks to create, open, publish, update, or edit a NeMo Fabric pull request, pull request description, or PR body.

If this repo-local guidance conflicts with generic GitHub publishing, connector, or plugin guidance, this skill wins for PR body format, validation language, and review handoff details.
