Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 3 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: account.sirv.com, scripts.sirv.com, www.sirv.studio.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

When to use it

  • Website Optimization: Reduce the weight of images on a website to improve page load times.
  • Content Creation: Optimize images before publishing them online (e.g., blog posts, social media).
  • Email Marketing: Decrease email attachment sizes for faster sending and receiving.
  • Image Storage: Compress images before storing them in cloud storage or archives.

Key capabilities

  • Image compression
  • File size reduction
  • Quality preservation
  • Integration into workflows

Example prompts

  • "Optimize this image: [image URL]"
  • "Compress this photo for web use."
  • "Reduce the file size of this image without losing too much quality."

Tips & gotchas

The skill's effectiveness depends on the original image format and complexity. Some images may already be optimized, resulting in minimal changes.
