SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires google-chrome, and includes scripts (resource) components.

What problem does it solve?

Manually taking screenshots of interactive, JavaScript-heavy MicroSims is inconsistent, time-consuming, and often fails to capture the fully rendered state or handle external CDN resources. This skill automates the process using Chrome headless, ensuring perfect, consistent captures.

Core Features & Use Cases

  • Automated Screenshot Capture: Uses Chrome headless mode to capture high-quality PNG images of MicroSims.
  • JavaScript & CDN Handling: Ensures visualizations with dynamic content and external libraries (p5.js, Chart.js) are fully rendered.
  • Standardized Output: Saves screenshots with consistent naming ({microsim-name}.png) and optimal dimensions for social media and documentation.
  • Use Case: A content creator needs a preview image for a new interactive physics MicroSim to share on social media and embed in documentation. This skill can generate a perfect screenshot with a single command.

Quick Start

Use the microsim-screen-capture skill to capture a screenshot of the 'bouncing-ball' MicroSim located at docs/sims/bouncing-ball.

Frequently Asked Questions about microsim-screen-capture

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate screenshots of JavaScript visualizations with external libraries?▼

Automate screenshots using Chrome headless to capture dynamic JavaScript visualizations that load external CDN libraries like p5.js and Chart.js. The skill uses headless rendering with web security disabled and file access enabled to ensure full resource loading and consistent output as PNG files.

Can I capture MicroSim screenshots for social media and documentation automatically?▼

Yes, this skill captures MicroSim visualizations as optimized PNG screenshots suitable for social media previews and documentation. It automates the entire process—rendering, waiting for full JavaScript execution, and saving with standardized naming—eliminating manual screenshot inconsistencies.

What does Chrome headless mode do for capturing interactive simulations?▼

Chrome headless renders interactive simulations in a browser environment without a GUI, enabling automated capture of fully rendered dynamic content. It handles JavaScript execution, CDN resource loading, and applies viewport sizing and scrollbar hiding for clean, consistent screenshots.

Do I need special configuration to screenshot MicroSims with p5.js and Chart.js?▼

No special configuration is needed—this skill handles p5.js and Chart.js visualizations automatically. Chrome headless is configured with flags for web security disabled and file access enabled, ensuring external CDN libraries render fully before capture.

Why is manual screenshotting of interactive visualizations problematic?▼

Manual screenshotting of JavaScript-heavy simulations fails to capture fully rendered states, misses external CDN resources, and produces inconsistent results across captures. Automation ensures reliable, high-quality output every time without manual intervention.

What are the limitations of capturing screenshots with Chrome headless?▼

Chrome headless captures static PNG output and does not preserve interactivity or animations. It requires Google Chrome to be installed and works best with simulations that render deterministically; complex or time-dependent animations may require viewport sizing and wait-time adjustments.
