The post, published on November 11, 2026, describes categories covering JavaScript libraries, browser APIs and web API hosts. It says the collection can be explored through tags generated from an analysis of each tool’s code, making the technical components used across the projects easier to browse.
According to the post, the analysis used tree-sitter to identify the JavaScript APIs, libraries and web API hosts used by each tool. The displayed tags include the JavaScript library @google/generative-ai and the browser-API label Built-in AI.
Willison also said he used remaining Fable 5.2 credits before a weekly reset to carry out the work. The supplied material does not identify what Fable 5.2 is or who provides it; the tool count and implementation details come from the single supplied source.
