Public Skills
solidity-erc-standards
by whackur
ERC token standard implementation guidelines for Solidity. Use when implementing, extending, or reviewing ERC20, ERC721, ERC1155, or ERC4626 contracts. Covers interface compliance, common pitfalls, OpenZeppelin and Solady implementations, extension patterns, and testing strategies. Triggers on tasks involving token implementation, NFT contracts, vault standards, or ERC compliance.
solidity-security-best-practices
by whackur
Smart contract security best practices for Solidity development. Use when writing, reviewing, or auditing Solidity code. Covers reentrancy prevention, access control patterns, safe external calls, input validation, upgrade safety, and OWASP Smart Contract Top 10 vulnerabilities. Triggers on tasks involving security, vulnerability detection, access control, CEI pattern, ReentrancyGuard, SafeERC20, or smart contract auditing.
solidity-hardhat-development
by whackur
Hardhat 3 development workflow for Solidity smart contracts. Use when building, testing, or deploying with Hardhat 3.x (hardhat, ignition, EDR). Covers ESM-first project setup, defineConfig, Solidity-native tests, TypeScript tests, multichain support, Hardhat Ignition deployment, and hook-based plugin system. Triggers on tasks involving hardhat init, hardhat build, hardhat test, hardhat ignition, or Hardhat-based Solidity development.
solidity-adversarial-analysis
by whackur
Adversarial scenario analysis and threat modeling for Solidity smart contracts. Use when analyzing contracts from an attacker's perspective, identifying multi-step attack vectors, or performing threat modeling. Covers flash loan attacks, oracle manipulation, MEV/front-running, governance exploits, reentrancy scenarios, access control bypasses, economic logic exploits, and cross-contract composability risks. Triggers on tasks involving adversarial analysis, threat modeling, attack scenarios, attack vectors, exploit analysis, or red team review.
solidity-foundry-development
by whackur
Foundry development workflow for Solidity smart contracts. Use when building, testing, or deploying with Foundry (forge, cast, anvil). Covers project setup, foundry.toml configuration, testing patterns, fuzz testing, invariant testing, fork testing, cheatcodes, deployment scripts, and debugging. Triggers on tasks involving forge build, forge test, forge script, cast, anvil, or Foundry-based Solidity development.
solidity-code-review
by whackur
Smart contract code review and security audit methodology for Solidity. Use when reviewing, auditing, or assessing the security of Solidity code. Provides structured review process, severity classification, key inspection areas, and OWASP SCWE integration. Triggers on tasks involving code review, security audit, vulnerability assessment, smart contract review, or best practices check.
solidity-gas-optimization
by whackur
Gas optimization patterns for Solidity smart contracts. Use when optimizing contract deployment costs, runtime gas usage, or storage efficiency. Covers storage packing, custom errors, immutable variables, calldata optimization, loop patterns, assembly usage, and Solady gas-optimized alternatives. Triggers on tasks involving gas optimization, storage layout, deployment cost reduction, or EVM efficiency.
