HOW TO READ THIS REPORT

Action plan is what to do next — copy-pasteable changes prioritized by impact. Category visibility is the real GEO test: when a user asks an AI a brand-free question that should surface stdlib-js/stdlib, does the AI actually recommend you — or your competitors? Objective checks verify the metadata signals AI engines weight first. Self-mention check detects whether AI even knows you exist by name.

Action plan — copy-paste fixes

3 prioritized changes generated by gemini-2.5-flash. Mark items done after you ship the fix.

OVERALL DIRECTION
  • highreadme#1
    Strengthen README's opening statement with core purpose and environments

    Why:

    CURRENT
    We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib ([/ˈstændərd lɪb/][ipa-english] "standard lib") is a standard library with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
    COPY-PASTE FIX
    stdlib is the fundamental numerical and scientific computing library for JavaScript and TypeScript, designed for high-performance execution in both browsers and Node.js environments. It provides a comprehensive collection of robust, high-performance libraries for mathematics, statistics, data processing, streams, and more.
  • mediumtopics#2
    Add 'high-performance' topic

    Why:

    CURRENT
    javascript, js, library, math, mathematics, node, node-js, nodejs, numerical, numerical-computing, science, scientific, scientific-computing, standard, statistics, stats, stdlib, typescript, utilities, utils
    COPY-PASTE FIX
    javascript, js, library, math, mathematics, node, node-js, nodejs, numerical, numerical-computing, science, scientific, scientific-computing, standard, statistics, stats, stdlib, typescript, utilities, utils, high-performance
  • lowreadme#3
    Ensure README starts with direct, concise text

    Why:

    COPY-PASTE FIX
    Remove any empty `<section>` or `<div>` tags, or other non-content elements, that appear before the primary introductory sentence in the README's source.
