What coding agents get wrong in Solidity and smart contracts

Agents write contracts open to reentrancy, skip checks on external calls, and trust tx.origin. Tests cover the happy path and skip fork tests against mainnet state.

Skills that help

Trail of Bits skills for contract review and vulnerability scans, plus skills for Solidity security and tests in Hardhat or Foundry.

Cursor rules: the database holds 13 Cursor rule files (.mdc) tagged Solidity and smart contracts (general-solidity-typescript-node-js-next-js-rule, solidity, solidity-best-practices, solidity-documentation, solidity-general-rules, solidity-performance-optimization, and more). Cursor reads them from .cursor/rules/. Other agents load SKILL.md skills, so most picks here are skills.

3 picks to start with

1. solidity-security

Master smart contract security best practices to prevent common vulnerabilities and implement secure Solidity patterns.

These 3 fit Solidity and smart contracts in general. The scan box opens with a sample Solidity and smart contracts description you can edit. A scan reads your repo or description, shows the match count and 2 picks free, and the full curated list (up to 30 picks with install commands, reasons and overlap notes) costs $9 once.

Where each agent loads Solidity and smart contracts skills

Claude Code: project folder .claude/skills/, install flag --agent claude-code
Cursor: project folder .cursor/skills/ or .agents/skills/, install flag --agent cursor
Codex: project folder .agents/skills/, install flag --agent codex
GitHub Copilot: project folder .github/skills/ or .agents/skills/, install flag --agent github-copilot

npx skills add owner/repo --skill skill-name --agent claude-code

How we count

We match project tags against 99,639 skills from 7,206 public GitHub repos (refreshed 2026-10-18). A skill built for another framework or language is left out, and so is a skill below our relevance floor. The picks on this page come from the ranked list for these tags. We favor broad practice skills over single-task ones. Licenses are shown as each repo declares them. Read a skill before you install it.

Questions

What agent skills should I use for Solidity and smart contracts?

Start with a broad practice skill built for Solidity and smart contracts, then add skills for testing and review. In our database 200 skills are tagged for Solidity and smart contracts and 450 skills match a typical Solidity and smart contracts project. The picks on this page are a place to start. A scan of your repo ranks the full list for your tasks.

Is a skill a substitute for an audit?

No. A skill helps your agent avoid known mistakes. Contracts that hold funds need a human audit.

Are there Cursor rules for Solidity and smart contracts?

Yes. The database holds 13 Cursor rule files (.mdc) tagged Solidity and smart contracts. Cursor loads them from .cursor/rules/. Claude Code, Codex and Copilot do not read .mdc rules, so pick SKILL.md skills for those agents.

Where do Solidity and smart contracts skills go for Claude Code, Cursor, Codex and Copilot?

Claude Code reads .claude/skills/, Cursor reads .cursor/skills/ or .agents/skills/, Codex reads .agents/skills/, and GitHub Copilot reads .github/skills/ or .agents/skills/. The install command takes --agent with the agent name and copies the skill folder there.

Why 3 picks here?

The right list depends on your exact stack and tasks. Run a free scan for your project to see its match count and 2 picks. The full curated list is $9 once.
