This may be a repeated review request. Before writing a new review, inspect prior PR comments, bot comments, reviews, inline comments, and the commit timeline via GitHub. Compare prior findings against commits pushed after those comments, then only repeat findings that still exist in the current diff/current file state.
Read the base checkout's AGENTS.md and CONTRIBUTING.md. Independently discover every project skill matching the character of the change, read each matching SKILL.md and its task-required references, and apply that guidance to implementation correctness as well as PR readiness. The workflow deliberately provides no skill list.
