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 trailofbits/skills at 82fe822625.

    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

This skill enables AI agents to generate text using a specific writing style and structure, likely mimicking or adhering to pre-defined patterns. It's designed to produce consistent and predictable output suitable for technical documentation, reports, or other structured content creation tasks. The agent can leverage this skill to create documents that are formatted in a particular way.

When to use it

  • Generating standardized technical documentation following specific company guidelines.
  • Creating repetitive report sections with consistent formatting and language.
  • Producing draft versions of legal disclaimers or policy statements.
  • Automating the creation of structured data entries from unstructured text sources.

Key capabilities

  • Style adherence
  • Structural consistency
  • Pattern replication
  • Document generation

Example prompts

  • "Write a section for our API documentation describing endpoint /users in Harness style."
  • "Generate a draft policy statement on data retention, following the established template."
  • “Create a report summary using the standard reporting format.”

Tips & gotchas

The effectiveness of this skill depends heavily on the quality and specificity of the underlying writing patterns it's trained on. Ensure that any templates or style guides used are clear and well-defined for optimal results.
