Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    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.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned umbraco/umbraco-cms-backoffice-skills at 78b551bf9c.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

The umbraco-file-upload-preview skill enables AI agents to inspect file metadata and preview content directly within the Umbraco back office. It streamlines the workflow by allowing agents to verify document details before committing changes to the CMS.

When to use it

  • Verifying Content: Confirming that an uploaded image or document matches the expected format and size before saving.
  • Content Updates: Quickly checking existing file properties, such as creation dates or authors, during content editing tasks.
  • Media Library Management: Identifying specific files in a large library to ensure they are ready for publication or further processing.
  • Quality Assurance: Validating that AI-generated or user-uploaded assets meet specific project requirements prior to integration.

Key capabilities

  • Displays file metadata including name, type, and size.
  • Renders previews of supported media formats directly in the UI.
  • Integrates seamlessly with the Umbraco back office interface for immediate feedback.

Example prompts

  • "Preview the latest image uploaded to the 'Hero Section' folder in the media library."
  • "Check the metadata and preview of the document titled 'Q3_Report.pdf' before I publish it."
  • "List all video files currently stored in the 'Marketing_Assets' folder and show their previews."

Tips & gotchas

Ensure the AI agent has appropriate permissions to access the specific media folders or documents it needs to inspect. Preview functionality is limited to file types supported by the Umbraco back office's built-in previewer.
