SKILL: solidity-dev

Purpose

Design and implement secure Solidity smart contracts with explicit security controls, tests, and deterministic build/validation steps.

When to Use

• The task requires a new contract (ERC-20/721/1155) or extending an existing one.
• You need secure patterns (access control, pausable, reentrancy protection).
• You need Hardhat/Foundry test scaffolding.

Inputs

• contract_spec (required, object|string): requirements, roles, invariants, events.
• standard (optional, enum: erc20|erc721|erc1155|custom).
• tooling (optional, enum: hardhat|foundry).
• security_constraints (optional, string[]): e.g., “no upgradeability”, “pausable required”.
• deployment_target (optional, string): local/testnet/mainnet (mainnet requires explicit user approval).
