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 otrebu/agents at bfdafbf23c.

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

About this skill

What it does

The analyze-size skill allows an AI agent to determine the size of files or directories. It can provide a human-readable representation of file sizes (e.g., "12 MB") and calculate directory totals, offering insights into storage usage. This is useful for understanding disk space consumption and identifying large files that might be candidates for archiving or deletion.

When to use it

  • Disk Space Management: An agent can analyze a user's Downloads folder to identify the largest files taking up space.
  • File Archiving: Determine which files exceed a certain size threshold, suggesting they should be archived.
  • Cleanup Recommendations: Identify large directories and suggest potential cleanup actions based on file age or type.
  • Storage Planning: Estimate storage needs for backups by analyzing the sizes of important data folders.

Key capabilities

  • File Size Determination: Accurately calculates the size of individual files.
  • Directory Size Calculation: Recursively determines the total size of directories and their contents.
  • Human-Readable Output: Presents file sizes in a user-friendly format (e.g., KB, MB, GB).

Example prompts

  • "How big is my Downloads folder?"
  • "What are the 10 largest files in /var/log?"
  • "Find all files larger than 100MB in the Documents directory."

Tips & gotchas

The skill requires appropriate file system permissions to access and analyze directories. Be mindful of potentially very large directories, as calculating their size can take time.
