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 schwepps/skills at 8aa9a4e0ee.

    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 Solidity Auditor skill analyzes smart contracts written in Solidity to identify potential vulnerabilities and areas for improvement. It performs audits based on user requests, covering security vulnerabilities, gas optimization, storage patterns, and code architecture. The audit process adapts to the specific version of Solidity used in the contract being analyzed, considering version-specific considerations.

When to use it

  • Before deploying a new smart contract to ensure its security.
  • When performing routine maintenance on existing smart contracts.
  • To identify gas optimization opportunities and reduce transaction costs.
  • To review the architecture of a smart contract for potential design flaws.
  • Specifically when auditing DeFi protocols, which require both security and architectural reviews.

Key capabilities

  • Audit Type Selection: Determines audit type based on user request (Full Audit, Security Focused, Gas Optimization, Storage Optimization, Architecture Review, or DeFi Protocol).
  • Solidity Version Awareness: Considers version-specific vulnerabilities (e.g., SafeMath usage for pre-0.8.0 contracts, unchecked blocks for 0.8.0+).
  • Static Analysis: Performs mental checks using a security checklist to identify potential issues like access control problems and arithmetic errors.
  • Vulnerability Assessment: Evaluates vulnerabilities based on severity (Critical, High, Medium) referencing OWASP standards.
  • Optimization Analysis: Provides recommendations for gas and storage optimization when requested.
  • Report Generation: Structures findings using a predefined report template.

Example prompts

  • "Perform a full audit of this smart contract."
  • "Can you perform a security-focused audit, looking for common vulnerabilities?"
  • "Analyze this contract for gas optimization opportunities."
  • “Review the architecture of this DeFi protocol.”

Tips & gotchas

  • Providing context about the smart contract's purpose, deployment chain(s), and expected user flows will improve the quality of the audit.
  • The skill adapts to Solidity version specifics; ensure the correct version is identified during analysis.
  • The auditor utilizes mental checks based on established patterns and references, so it’s not a fully automated tool.
