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 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 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: openoffice.org.

    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.

  • 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 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

About this skill

What it does

The tfriedel-xlsx skill enables AI agents to work with Excel files (.xlsx) by reading, writing, and manipulating spreadsheet data. It supports operations like parsing cell values, formatting cells, and generating new spreadsheets based on structured input.

When to use it

  • Automating data entry or report generation from structured text inputs
  • Extracting specific data from large Excel files for analysis or transformation
  • Creating custom Excel templates dynamically based on user-defined parameters

Key capabilities

  • Reading and writing .xlsx files
  • Manipulating cell values and formatting
  • Generating new spreadsheets from structured input

Example prompts

  • "Create an Excel file with columns 'Name' and 'Score' using the following data: John - 95, Sarah - 88."
  • "Extract all rows where the 'Status' column is 'Completed' from this spreadsheet."
  • "Format the 'Date' column in this Excel sheet to match the MM/DD/YYYY format."

Tips & gotchas

  • Ensure input data is well-structured for accurate spreadsheet generation.
  • File size limitations may apply when working with very large .xlsx files.
