changeset-validation

Quick Review

Well-structured skill for validating changesets using LLM judgment against git diffs. The description clearly explains when to use it (packages/ or .changeset/ modifications, PR compliance checks). SKILL.md provides good workflow overview with clear quick-start commands for both local and CI contexts. Task knowledge is strong with referenced validation-prompt.md as the shared source of truth and specific scripts for execution. Structure is clean with appropriate separation of concerns. Novelty is moderate - while LLM-based changeset validation is useful, the task is relatively straightforward diff analysis that a CLI agent could attempt, though this skill meaningfully reduces token cost by pre-packaging the validation logic and prompts. Minor improvement areas: description could mention the experimental/preview patch bump exception and pre-1.0 major bump restriction for completeness.
