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

The substrate-vulnerability-scanner skill allows AI agents to identify potential security vulnerabilities in Substrate blockchain networks. It analyzes the network's configuration and code for common issues, providing detailed reports that can be used to improve overall security posture. This skill is designed to assist developers and operators in proactively addressing risks within their Substrate deployments.

When to use it

  • Pre-deployment Security Audits: Before launching a new Substrate chain or runtime upgrade, scan for vulnerabilities.
  • Regular Security Checks: Schedule periodic scans of existing Substrate networks to detect newly introduced issues.
  • Incident Response: Following a security incident, quickly assess the network's configuration and code for related vulnerabilities.
  • Runtime Upgrade Validation: Ensure that new runtime versions do not introduce regressions in security posture.

Key capabilities

  • Vulnerability scanning of Substrate networks.
  • Detailed vulnerability reports.
  • Identification of common security issues.

Example prompts

  • "Scan this Substrate network for vulnerabilities: [network URL]"
  • "Analyze the runtime code at this repository for potential security flaws."
  • “Generate a report detailing all identified vulnerabilities in my Substrate chain.”

Tips & gotchas

This skill requires access to the Substrate network or its codebase being analyzed. The accuracy of the scan depends on the completeness and correctness of the provided information; ensure accurate URLs and code repositories are supplied for best results.
