          Read and implement the highest-voted planned request on the FeatureJet board "${FEATUREJET_BOARD_SLUG}" in this checked-out repository.

          Use the hosted FeatureJet MCP server at https://mcp.featurejet.com/mcp with the FEATUREJET_API_KEY already present in your environment. Follow this current queue-pull sequence exactly:
          1. Call get_queue for board slug "${FEATUREJET_BOARD_SLUG}". It returns the top unclaimed posts in the board owner's curated order.
          2. If a post is returned, call get_post for the first post and list_comments for that same post before deciding what to change.
          3. If the queue is empty, report that no work was selected and leave the repository unchanged.

          Work only in this repository. Run the relevant tests. Do not call update_post, create_comment, or any other FeatureJet write tool; do not change a FeatureJet status, push a branch, or open a pull request. The resulting working-tree diff will be saved for a human review.
