smart-contract-audit

smart-contract-audit is a skill for Claude Code, Codex from greatpie/smart-contract-audit-skill. It costs 80 tokens per session (953 once invoked), scanned A, original, no licence file.

A script-backed workflow for auditing Solidity smart-contract repositories that run on the Ethereum Virtual Machine, the software environment used by Ethereum-compatible networks. It follows an EVMbench-style process to find, test, and help patch serious loss-of-funds vulnerabilities.

In plain words
What is it for?
Auditing Solidity repositories from a URL or local path, checking high-severity vulnerabilities, validating exploits, and proposing safer fixes.
Why use it?
It organises the technical setup and investigation needed for a security audit. Testing whether a suspected flaw can actually be exploited helps distinguish real risks from false alarms.

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

smart-contract-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 10d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (scripts/audit.sh, scripts/bootstrap.sh, scripts/generate_exploit_scaffold.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
