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 pseudoyu/agent-skills at 2364eaed43.

    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 provides a comprehensive guide to optimizing gas costs in Solidity smart contracts. It offers over 80 techniques, categorized by impact and risk, drawing from the RareSkills Book of Gas Optimization. The tool helps developers identify areas for improvement in their code, leading to reduced transaction fees during deployment or execution.

When to use it

  • When writing new Solidity smart contracts.
  • During reviews or audits of existing contracts.
  • To optimize gas costs before deploying a contract.
  • When refactoring storage layouts within a contract.
  • When implementing interactions between different smart contracts.
  • When choosing between different design patterns (e.g., ERC721 vs ERC1155).

Key capabilities

  • Storage Optimization: Techniques to minimize gas usage related to data stored on the blockchain.
  • Deployment Optimization: Strategies for reducing gas costs during contract deployment.
  • Calldata Optimization: Methods for efficiently handling function input data.
  • Design Pattern Guidance: Recommendations for selecting efficient design patterns, including token standards like ERC721 and ERC1155.
  • Cross-Contract Call Optimization: Techniques to reduce gas costs when interacting between contracts.
  • Compiler Optimization Suggestions: Advice on leveraging compiler features to improve gas efficiency.

Example prompts

  • "Analyze this Solidity code for potential gas optimization opportunities." (followed by the code)
  • "What are some strategies for storage optimization in Solidity?"
  • "Should I use ERC721 or ERC1155 for my NFT project, and why?"

Tips & gotchas

  • Prioritize "Storage Optimization" techniques first as they have the most critical impact.
  • Be cautious when applying "Dangerous Techniques," as they carry a high risk of introducing vulnerabilities.
  • Consider using bytes calldata instead of bytes memory in function parameters to avoid unnecessary data copying.
