name	audit
description	Deep EVM smart contract security audit system. Use when asked to audit a contract, find vulnerabilities, review code for security issues, or file security issues on a GitHub repo. Covers 500+ non-obvious checklist items across 19 domains via parallel sub-agents. Different from the security skill (which teaches defensive coding) — this is for systematically auditing contracts you didn't write.

EVM Smart Contract Audit

A full audit system for any EVM contract. Runs parallel specialist agents against domain-specific checklists, synthesizes findings, and files GitHub issues.

The Checklists

20 specialized skills covering every major vulnerability domain. Fetch the master index first:

https://raw.githubusercontent.com/austintgriffith/evm-audit-skills/main/evm-audit-master/SKILL.md

The master index contains:

• Full routing table (which skills to load for which contract types)
• The complete audit methodology (recon → parallel agents → synthesis → issues)
• Standard finding format with severity definitions

All 20 skill checklists are at:

How To Run An Audit

1. Fetch the master skill (link above) — it has the full pipeline
2. Read the contract(s)
3. Select 5-8 skills using the routing table
4. Spawn one opus sub-agent per skill (parallel)
5. Each agent walks its checklist and writes findings-<skill>.md
6. Synthesize all findings into AUDIT-REPORT.md
7. File GitHub issues for Medium severity and above
