String is a runtime that moves tool knowledge out of context and renders it back one view at a time as markdown, with a single document declaring views, typed actions, navigation and credentials behind two verbs. Correct staging drops wrong-action selection from 28% to 2%. On an 87-task benchmark across six models, converting curated skills into on-demand apps matched aggregate success within 1.3 points using 33.5% fewer tokens, with the resident interface a constant 53 tokens regardless of catalog size. Progressive disclosure has a measurable optimum and both directions off it hurt.
