The agent must recognise that .tessl/plugins/ is a cache, not a source location, place the new plugin somewhere it controls and commits, leave the existing cache untouched, and validate with the correct lint command. This directly exercises the guidance added to build-composition to stop agents thrashing on where to author plugin source.",
