AI Summary: The Spacebar server project needs a fix for its `/channels/:channel_id/messages/:message_id/reactions/:emoji` endpoint. Currently, it ignores the `limit` parameter when fetching reactions, sending too many. The task involves adding support for the `limit` parameter to restrict the number of reactions returned, aligning with the expected behavior of limiting the response to the specified amount. This requires modifying the API server code to correctly handle the `limit` parameter and potentially updating the documentation.
