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 0xlayerghost/solidity-agent-kit at ad854ef3a7.

    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 empowers AI agents to perform security audits and risk assessments specifically for DeFi protocols. It leverages the Solidity Agent Kit to analyze smart contract code, identify vulnerabilities, and evaluate potential threats within decentralized finance ecosystems.

When to use it

  • Before deploying a new smart contract to production to catch critical bugs early.
  • During due diligence when evaluating the safety of an existing DeFi protocol or dApp.
  • To simulate attack vectors and test the resilience of financial logic against exploits.
  • When integrating third-party libraries into a DeFi application to ensure no supply chain risks exist.

Key capabilities

  • Automated analysis of Solidity smart contract code for security flaws.
  • Identification of common DeFi-specific vulnerabilities such as reentrancy and overflow issues.
  • Risk assessment generation based on the findings from the code review.
  • Integration with the solidity-agent-kit framework for deep technical inspection.

Example prompts

  • "Audit this Solidity contract for potential reentrancy attacks before we deploy it."
  • "Analyze the security posture of this DeFi lending protocol's smart contracts."
  • "Identify any overflow or underflow vulnerabilities in this token swap function."

Tips & gotchas

Ensure you provide clean, compilable Solidity code to the agent for the most accurate analysis. While this tool is powerful for static analysis, it should be complemented with live testing and formal verification for high-value assets.
