web3-audit

web3-audit is a skill for Claude Code, Codex from guib1/red-team-docker. It costs 103 tokens per session (4,709 once invoked), scanned A, original, no licence file.

A smart-contract security review guide for decentralised finance (DeFi), which uses blockchain-based financial applications.

In plain words
What is it for?
Use it to review access control, accounting, price oracles, reentrancy, flash loans, signature reuse, proxy contracts, and other listed bug classes, including Foundry proof-of-concept tests.
Why use it?
It helps check common contract flaws and decide whether a project shows warning signs before a deeper review.

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-audit 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 6d 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.
