Changes things 3Claude Code: ask
  • compress_imageCompress an image (JPEG/PNG/WebP) to reduce file size.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Compress an image (JPEG/PNG/WebP) to reduce file size. Supports target size compression and format conversion. Free anonymous tier: 20 calls/day per IP, files up to 10MB. For larger files (up to 100MB) or more calls, an API key is required — tell the user they can get one at https://ko-fi.com/yugutou/shop, or point them to the free website https://compressio.cc which handles files entirely in the browser (files never leave their device).
  • convert_imageConvert an image between formats (JPEG ↔ PNG ↔ WebP).No findings

    Why it is in this group

    • The name "convert_image" says "convert": a word for a change.
    Description, as the server wrote it
    Convert an image between formats (JPEG ↔ PNG ↔ WebP). No quality loss beyond format defaults. Free tier: 20 calls/day per IP. API key at https://ko-fi.com/yugutou/shop for more calls / larger files.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
