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

    Scanned smallnest/langgraphgo at 8babee09de.

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

About this skill

What it does

The smallnest-xlsx skill allows AI agents to process and manipulate data within Excel (.xlsx) files. It can read data from existing spreadsheets, write new data into spreadsheets, and perform basic spreadsheet operations like creating new sheets or modifying cell values. This enables automation of tasks involving structured data stored in a common file format.

When to use it

  • Data Entry Automation: Automatically populate an Excel sheet with information retrieved from a website or database.
  • Report Generation: Create spreadsheets summarizing data extracted from various sources.
  • Spreadsheet Updates: Modify existing spreadsheet data based on specific conditions or calculations.
  • Data Consolidation: Combine data from multiple spreadsheets into a single, unified file.

Key capabilities

  • Reading data from .xlsx files
  • Writing data to .xlsx files
  • Creating new sheets within an Excel file
  • Modifying cell values in existing sheets

Example prompts

  • "Read the sales data from 'sales_report.xlsx' and summarize it."
  • "Create a new spreadsheet called 'inventory.xlsx' with columns for item name, quantity, and price."
  • "Update the value in cell A1 of 'budget.xlsx' to 1000."

Tips & gotchas

The skill requires access to the .xlsx file path. Ensure the AI agent has appropriate permissions to read from and write to the specified location.
