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 3 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: apache.org, evil.com, xml.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 trailofbits/skills at 82fe822625.

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

About this skill

What it does

This skill, sharp-edges, likely provides a way to identify and mitigate potential security vulnerabilities or edge cases in code or systems. The exact capabilities aren't detailed, but the name suggests a focus on finding subtle flaws that might be missed by standard analysis techniques. It’s intended for use in improving the robustness of software and infrastructure.

When to use it

  • During code reviews to proactively identify potential vulnerabilities.
  • When assessing the security posture of new or existing systems.
  • To harden configurations against unexpected behavior.
  • As part of a broader vulnerability management program.

Key capabilities

  • Identification of subtle flaws (implied by name)
  • Security analysis (implied by use case)
  • Robustness improvement (implied by use case)

Example prompts

  • "Analyze this code snippet for potential edge cases."
  • "Review this configuration file and highlight any areas that could be exploited."
  • "Can you identify any vulnerabilities in this system's architecture?"

Tips & gotchas

The skill’s effectiveness likely depends on the quality of the input provided. It is best used with clear, well-defined code or system descriptions to ensure accurate analysis.
