> defi-security

[AUTO-INVOKE] MUST be invoked BEFORE deploying DeFi contracts (DEX, lending, staking, LP, token). Covers anti-whale, anti-MEV, flash loan protection, launch checklists, and emergency response. Trigger: any deployment or security review of DeFi-related contracts.

> foundry

You are an expert in Foundry, the blazing-fast Ethereum development toolkit written in Rust. You help developers write, test, deploy, and debug Solidity smart contracts using Forge (testing), Cast (CLI interactions), Anvil (local node), and Chisel (Solidity REPL) — with native Solidity testing (no JavaScript), fuzz testing, gas optimization, and fork testing against mainnet state.

> solana

You are an expert in Solana blockchain development. You help developers build on-chain programs (smart contracts) in Rust, interact with the Solana network using @solana/web3.js, create tokens (SPL), build NFT collections, and integrate with wallets — leveraging Solana's 400ms block times, parallel transaction processing, and sub-cent fees for high-throughput applications.

> claude-code-usage

[AUTO-INVOKE] MUST be invoked at the START of each new coding session. Covers context management, task strategies, and Foundry-specific workflows. Trigger: beginning of any new conversation or coding session in a Solidity/Foundry project.

> solidity-coding

[AUTO-INVOKE] MUST be invoked BEFORE writing or modifying any Solidity contract (.sol files). Covers pragma version, naming conventions, project layout, OpenZeppelin library selection standards, oracle integration, and anti-patterns. Trigger: any task involving creating, editing, or reviewing .sol source files.

> solidity-security

[AUTO-INVOKE] MUST be invoked BEFORE writing or modifying any Solidity contract (.sol files). Covers private key handling, access control, reentrancy prevention, gas safety, and pre-audit checklists. Trigger: any task involving creating, editing, or reviewing .sol source files.

> thirdweb

You are an expert in thirdweb, the complete web3 development platform that provides SDKs, pre-built smart contracts, wallet infrastructure, and payment solutions. You help developers build dApps using thirdweb's React hooks, contract deployment (ERC-20, ERC-721, ERC-1155, marketplace), embedded wallets, fiat-to-crypto onramps, and multi-chain support — from prototype to production without deep blockchain expertise.

#react#web3⭐ 1

> solidity-deploy

[AUTO-INVOKE] MUST be invoked BEFORE deploying contracts or writing deployment scripts (*.s.sol). Covers pre-flight checks, forge script commands, post-deployment validation, and verification. Trigger: any task involving forge script, contract deployment, or block explorer verification.

> wagmi

Build React dApps with wagmi and viem. Use when a user asks to connect wallets in React, read blockchain data in components, send transactions from a frontend, or build a Web3 user interface.

#frontend#react#web3⭐ 1

> ethers-js

Interact with Ethereum and EVM blockchains using ethers.js. Use when a user asks to connect to Ethereum, read blockchain data, send transactions, interact with smart contracts, or build a dApp frontend.

#frontend#web3⭐ 1

> solidity

Write smart contracts with Solidity for Ethereum. Use when a user asks to create a smart contract, build an ERC-20 token, deploy to Ethereum, write NFT contracts, or develop DeFi protocols.

> solidity-debug

[AUTO-INVOKE] MUST be invoked when debugging failed on-chain transactions. Covers transaction receipt analysis, gas diagnosis, calldata decoding, revert reason extraction, and state verification. Trigger: any task involving failed tx analysis, revert debugging, or on-chain transaction troubleshooting.

> solidity-testing

[AUTO-INVOKE] MUST be invoked BEFORE writing or modifying any test files (*.t.sol). Covers test structure, naming conventions, coverage requirements, fuzz testing, and Foundry cheatcodes. Trigger: any task involving creating, editing, or running Solidity tests.

#testing#web3⭐ 1

> solidity-audit

Security audit and code review checklist. Covers 30+ vulnerability types with real-world exploit cases (2021-2026) and EVMbench Code4rena patterns. Use when conducting security audits, code reviews, or pre-deployment security assessments.
