⚡ 1-Click Install Prompt (For your AI Assistant)

If you are using Antigravity, Claude Code, or other agentic coding assistants, copy and paste this single prompt directly into your chat:

Please install and set up this GitHub metadata automation skill:
https://github.com/Sacilave/github-info-injector.git
After installation, inspect the current repository and generate an automated console injection script for its description and topics.

💡 Why This Exists

GitHub's repository settings web interface has a well-known friction point:

1. No batch paste for Topics: Pasting comma-separated keywords into the Topics input field pastes the entire string as a single tag instead of splitting it into individual tags. Users are forced to type and hit enter up to 20 times manually.
2. Suboptimal SEO & GEO copy: Most repository descriptions are either missing, filled with generic buzzwords ("An awesome, blazingly fast library..."), or lack high-density entity keywords required by traditional search engines and AI models (ChatGPT, Perplexity, Google AI Overviews).

github-info-injector solves both issues:

• Analyzes your codebase to generate a function-first, fluff-free English description and up to 20 structured topics.
• Generates a ready-to-run browser console script that leverages native React property setters to inject both Description and all 20 Topics asynchronously in under 2 seconds.

📐 SEO & GEO Engineering Standards

This tool enforces strict information architecture principles:

1. Function First, Modifiers Last:
   • ❌ Fluff: "The most revolutionary and blazing-fast multi-threaded HTTP crawler for developers."
   • ✅ Function-first: "HTTP crawler to extract structured HTML datasets with asynchronous multi-threading and proxy rotation."
2. Length Guardrails:
   • Strictly targets 140 to 180 characters to ensure full visibility on GitHub mobile web and Google Search SERP snippets without ellipses truncation.
3. Entity Clustering for Topics:
   • Selects up to 20 lowercase kebab-case tags spanning runtime stack, core domain, integrations, and search intents.
4. Strict Privacy Sanitization:
   • Strips local paths (C:\Users\...), private keys, service account credentials, internal ports, and corporate intranets.

🚀 How to Use

Step 1: Run the Skill in Your Project

Run /github-info-injector inside any codebase. The agent will read your manifests (package.json, Cargo.toml, etc.) and docs, then return an automated JavaScript snippet.

Step 2: Inject in GitHub Settings (1 Second)

1. Open your repository on GitHub.
2. Click the ⚙️ icon next to About on the right sidebar.
3. Press F12 to open DevTools, switch to the Console tab.
4. Paste the generated snippet and press Enter.
5. Click the green Save changes button. Done!

🛠️ Standalone Console Snippet Example

If you want to quickly test the script format manually in your browser console:

(async () => {
  const DESCRIPTION = "Automate URL submission to Google Search Indexing API v3 with zero-dependency proxy tunneling.";
  const TOPICS = ["google-indexing-api", "seo", "googlebot", "sitemap", "automation", "nodejs"];

  const setNativeValue = (el, val) => {
    const setter = Object.getOwnPropertyDescriptor(el.__proto__, 'value')?.set ||
                   Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype, 'value')?.set ||
                   Object.getOwnPropertyDescriptor(window.HTMLTextAreaElement.prototype, 'value')?.set;
    if (setter) setter.call(el, val); else el.value = val;
    el.dispatchEvent(new Event('input', { bubbles: true }));
    el.dispatchEvent(new Event('change', { bubbles: true }));
  };
  const sleep = (ms) => new Promise(r => setTimeout(r, ms));

  const desc = document.querySelector('input[name="repo_description"]') || document.querySelector('input#repo_description');
  if (desc) { desc.focus(); setNativeValue(desc, DESCRIPTION); console.log('✅ Description filled.'); }

  const topicInput = document.querySelector('input[name="repo_topics"]') || document.querySelector('input#repo_topics') || document.activeElement;
  if (topicInput && Array.isArray(TOPICS)) {
    for (const t of TOPICS) {
      topicInput.focus();
      setNativeValue(topicInput, t);
      topicInput.dispatchEvent(new KeyboardEvent('keydown', { key: 'Enter', code: 'Enter', keyCode: 13, which: 13, bubbles: true }));
      topicInput.dispatchEvent(new KeyboardEvent('keyup', { key: 'Enter', code: 'Enter', keyCode: 13, which: 13, bubbles: true }));
      await sleep(120);
    }
    console.log(`✅ ${TOPICS.length} topics added.`);
  }
  console.log('🎉 Done! Click "Save changes" in GitHub.');
})();

❓ FAQ

Q: Why didn't a regular forEach work on GitHub's topic input?

A: GitHub's web interface utilizes modern React / Primer WebComponents. Tag creation is an asynchronous state transition triggered by Enter key events. A synchronous loop overwrites the input value before React dispatches the tag creation event. This tool uses native prototype property setters and sequential 120ms tick pacing to ensure 100% reliability.

Q: Does this require GitHub Personal Access Tokens (PAT)?

A: No. It operates entirely client-side inside your own authenticated browser session via the DevTools console, eliminating token permissions management or credential leakage risks.
