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 jeffallan/claude-skills at 1be15d8064.

    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

What it does

The legacy-modernizer skill helps translate older, potentially outdated text or code into a more contemporary style. It can rephrase sentences to use current language and idioms, and adapt phrasing to align with modern communication patterns. This is useful for making legacy content feel fresh and relevant.

When to use it

  • Updating old marketing materials: Revamp brochures or website copy that feels dated.
  • Modernizing internal documentation: Refresh technical manuals or training guides written in an older style.
  • Adapting historical text: Make classic literature or documents more accessible to a modern audience.
  • Improving the tone of legal language: Simplify complex clauses for better understanding.

Key capabilities

  • Rephrasing sentences using contemporary language
  • Updating idioms and expressions
  • Adjusting phrasing to align with modern communication styles

Example prompts

  • "Modernize this paragraph: 'Pursuant to our previous correspondence, we hereby request your immediate remittance.'"
  • "Rewrite this sentence in a more conversational tone: 'The aforementioned procedure is critical for optimal functionality.'"
  • "Make this marketing copy feel less formal: 'We are pleased to announce the availability of our revolutionary new product.'"

Tips & gotchas

  • While it can improve readability, always review the modernized output for accuracy and context. The skill's interpretation may not perfectly align with the original intent.
