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 Algorand Vulnerability Scanner identifies security weaknesses in smart contracts deployed on the Algorand blockchain. It analyzes contract code for common vulnerabilities such as reentrancy, overflow/underflow issues, and improper access controls.

When to use it

  • Before deploying a new Algorand smart contract to ensure it is secure.
  • After updating an existing contract to verify that no new vulnerabilities were introduced.
  • As part of a routine security audit for Algorand-based applications.
  • To comply with industry standards or regulatory requirements for blockchain security.

Key capabilities

  • Detects common smart contract vulnerabilities specific to the Algorand platform.
  • Provides detailed reports on identified issues, including risk levels and suggested fixes.
  • Integrates with development workflows for automated scanning during testing phases.

Example prompts

  • "Scan this Algorand smart contract for security vulnerabilities."
  • "Check my Algorand contract code for reentrancy risks."
  • "Run a vulnerability scan on the latest version of my Algorand application."

Tips & gotchas

  • Ensure your contract code is in the correct format (e.g., TEAL or SDK-based) before scanning.
  • The scanner may not detect all edge-case vulnerabilities, so it should be used alongside manual reviews and other security tools.
