    "body_text": "The method distinguishes root instructions from references, schemas, scripts, assets and nested skills, then removes duplicated content without flattening the routing structure. On a production moderation skill, the authors report 38 percent fewer bundle tokens and 10.4 percent fewer end-to-end tokens with no measured quality loss; a less protected 71 percent compression setting lost up to 26 accuracy points. A multi-entry audit also checked standalone routes. Results come from the evaluated harness and do not guarantee safe compression for every bundle.",
