Developer tool slashes API payload size by 24.6x through field curation

The author of a developer tool measured the impact of curating API responses, finding that reducing the number of returned fields significantly decreased payload size. By limiting the output of the `list_articles` function to essential fields like ID, title, and engagement metrics, the tool reduced the JSON payload for five articles by 24.6 times, from 40,613 bytes to 1,649 bytes. This reduction was primarily driven by excluding the `body_markdown` field, which constituted 86% of a single article's raw payload, and redundant user information, highlighting the importance of payload optimization for AI agents.
