agentation-vanilla is a powerful visual annotation tool designed specifically for local development of vanilla JavaScript applications. This project serves as a lightweight alternative to Agentation, which is primarily tailored for React, offering similar functionality without requiring any installations or user accounts.

Key Features

• Inspect Mode: Easily hover over elements to view selectors, styles, and dimensions. Click to pin and copy relevant information.
• Annotate Mode: Drop numbered markers with notes by clicking on elements or selecting text, facilitating clear communication about modifications or issues.
• Intent Tags: Classify annotations as bugs, styles, features, or content to maintain organized records.
• Copy as Markdown: Generate structured markdown from annotations for seamless integration into AI tools like Claude Code or Cursor.
• Per-Page Persistence: All annotations remain intact during page refreshes and navigation, ensuring continuity in the annotation process.
• Shadow DOM Isolation: The tool operates without interfering with the existing styles in the application, preserving the original design.
• Compatible with Any Stack: This tool is versatile and works effectively with various tech stacks, or even without a backend.

Getting Started

Integrating agentation-vanilla into an application is straightforward. Simply add the following script tag to the HTML file:

<script src="https://cdn.jsdelivr.net/gh/mearnest-dev/agentation-vanilla@main/agentation-vanilla.js"></script>

Upon integration, a toolbar will effortlessly appear in the bottom-right corner of the application.

For development purposes, it can be conditionally loaded to avoid cluttering production environments:

<script>
  if (location.hostname === 'localhost') {
    const s = document.createElement('script');
    s.src = 'https://cdn.jsdelivr.net/gh/mearnest-dev/agentation-vanilla@main/agentation-vanilla.js';
    document.body.appendChild(s);
  }
</script>

Annotations from the agentation-vanilla can be exported in a clear, structured markdown format, ideal for documentation or task management:

## [style] Annotation 1
