web3-testing SKILL.md skillA
web3-testing from wshobson/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add wshobson/agents/web3-testing@git:20260522.be57c0bPins git:20260522.be57c0b in mdr.lock. Pin the fingerprint instead.

Test smart contracts comprehensively using Hardhat and Foundry with unit tests, integration tests, and mainnet forking. Use when testing Solidity contracts, setting up blockchain test suites, or validating DeFi protocols.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Web3 Smart Contract Testing
Master comprehensive testing strategies for smart contracts using Hardhat, Foundry, and advanced testing patterns.
## When to Use This Skill
- Writing unit tests for smart contracts
- Setting up integration test suites
- Performing gas optimization testing
- Fuzzing for edge cases
- Forking mainnet for realistic testing
- Automating test coverage reporting
- Verifying contracts on Etherscan
## Hardhat Testing Setup
```javascript
// hardhat.config.js
require("@nomicfoundation/hardhat-toolbox");
require("@nomiclabs/hardhat-etherscan");
require("hardhat-gas-reporter");
require("solidity-coverage");
module.exports = {
solidity: {
version: "0.8.19",
settings: {
optimizer: {
enabled: true,
runs: 200,
},
},
},
networks: {
hardhat: {
forking: {

How to install
mdr add wshobson/agents/web3-testing@sha256:563c541469d9f23dThe line at the top of this page pins the label git:20260522.be57c0b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
