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