new-contract

new-contract is a skill for Claude Code, Codex from protokol/solidity-typescript-hardhat-template. It costs 18 tokens per session (509 once invoked), scanned A, original, MIT.

A command workflow for creating a new Solidity smart contract, its tests, its deployment module, and related tasks according to an existing project pattern.

In plain words
What is it for?
Use it to scaffold ERC20, ERC721, ERC1155, or custom contracts with selected features, OpenZeppelin ownership, tests, and an Ignition deployment module.
Why use it?
It reduces the repeated setup work and helps keep the contract, tests, and deployment configuration consistent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

new-contract scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/new-contract

Scaffold a new Solidity contract following the project's existing patterns.

Instructions

  1. Ask the user for:

    • Contract name (PascalCase, e.g., MyToken)
    • Token standard (ERC20, ERC721, ERC1155, or custom)
    • Features needed (Ownable, Pausable, Burnable, etc.)
  2. Create the contract in contracts/<ContractName>.sol:

    • Use pragma solidity 0.8.28;
    • Import from @openzeppelin/contracts/
    • Follow the patterns in existing contracts (e.g., BasicERC20.sol)
    • Pass initialOwner to Ownable constructor (OpenZeppelin v5 pattern)
    • Include SPDX-License-Identifier: MIT
  3. Create the test file in test/<ContractName>.ts:

    • Use the setupFixture + loadFixture pattern from existing tests
    • Use top-level await hre.network.connect() for ethers/networkHelpers
    • Test constructor parameters, core functionality, and access control
    • Use revertedWithCustomError for OpenZeppelin error assertions
  4. Create the Ignition module in ignition/modules/<ContractName>Module.ts:

    • Follow buildModule pattern from existing modules
    • Use m.getParameter() with sensible defaults
    • Use m.getAccount(0) for owner/deployer
    • Export as default
  5. Create task files in tasks/<token-type>/:

    • Use Hardhat v3 task API: task().addOption().setInlineAction().build()
    • Include usage example in comment
    • Export named const
  6. Register tasks in hardhat.config.ts:

    • Import the new task(s)
    • Add to the tasks array
  7. Verify everything works:

    • Run npm run compile to verify the contract compiles
    • Run npm run test to verify tests pass
    • Run npm run sol:format:write to format the Solidity file
    • Run npm run format:write to format TypeScript files

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

new-contract is a skill published in the GitHub repository protokol/solidity-typescript-hardhat-template (48 stars, last pushed 2d ago), licensed MIT. It adds 18 tokens to every session and 509 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
