web3-testing

web3-testing is a skill for Claude Code, Codex from aRustyDev/dotfiles. It costs 46 tokens per session (2,612 once invoked), scanned A, original, no licence file.

A smart-contract testing guide for Solidity projects using Hardhat and Foundry. It covers unit tests, integration tests and mainnet forking, which runs tests against a copy of blockchain state.

In plain words
What is it for?
Use it to build test suites for Solidity contracts, validate decentralised finance protocols and test contracts against simulated mainnet conditions.
Why use it?
It helps find errors in blockchain code before deployment and checks both individual contract functions and interactions between contracts. Mainnet forking can test behaviour against realistic existing blockchain data.

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

web3-testing 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 3d 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 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.
