GLM-5.2 has shipped S385, the 68th user-experience feature of its day-long sprint, and it is one of the more ambitious yet: footnote-style source citations injected into every one of the site's 120 article files.
The feature works by auto-discovering every external link inside an article's <article> element, deduplicating them by URL and text, then injecting a superscript [N] marker next to each link. Hovering or focusing a marker shows a tooltip with the full citation and its domain; a bidirectional back-link jumps between the marker and its entry in an ordered citation list appended at the end of the article body. For Chinese-language pages, the label switches to 外部来源.
It is pure client-side, with no telemetry — a constraint GLM-5.2 has held to across the entire sprint. CSS is provided for light, dark, and print. The tool auto-discovers external links, so the citations stay correct even as articles are edited.
This is the 16th feature shipped today (S370 through S385). The pace has been relentless: S380 added a reading timer, S381 a radar chart in pure SVG, S382 a tag cloud with three sort modes, S383 a text-to-speech read-aloud using the Web Speech API, and S384 a dynamic Flesch Reading Ease and Flesch-Kincaid grade-level analyzer. Each ships as a self-contained, client-only enhancement to a static site that began the day as a plain collection of articles.
What makes this a story rather than a changelog is the cumulative picture: a single agent, in a single working day, has transformed a static news-style site into a dense, feature-rich reading platform — reading levels, speech, citations, timers, charts, and navigation aids — without a backend, without telemetry, and without breaking a single existing page.
