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 avdlee/core-data-agent-skill at 855ca7d0df.

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

About this skill

What it does

The core-data-expert skill enables AI agents to work with structured data formats like JSON, XML, and CSV. It provides tools for parsing, validating, transforming, and querying data efficiently.

When to use it

  • When you need to extract specific fields from a large dataset.
  • To convert data between different formats (e.g., JSON to CSV).
  • When performing validation checks on input data structures.
  • For building dynamic queries based on user-defined criteria.

Key capabilities

  • Parsing and validating JSON, XML, and CSV files
  • Transforming data between formats
  • Querying structured datasets using filters or conditions
  • Performing basic schema validation

Example prompts

  • "Convert this JSON file to a CSV format."
  • "Extract all entries where the status is 'active' from the dataset."
  • "Validate if this XML file conforms to the provided schema."

Tips & gotchas

  • Ensure input data is well-formed before attempting transformation or validation.
  • Some advanced querying features may require additional configuration or plugins.
