Smart Contract Security

pluginagentmarketplace/custom-plugin-blockchain

Covers the essential vulnerability patterns you need to know,reentrancy, access control failures, oracle manipulation, precision loss,with before/after code examples for each. The skill walks through a systematic audit process from static analysis with Slither and Mythril to fuzz testing and invariant checks in Foundry. What's genuinely useful here is the severity classification table and the audit checklist that maps common DeFi-specific risks like flash loan attacks and sandwich prevention. You get practical tooling commands and incident response steps, not just theory. The vulnerability quick reference alone saves you from having to remember which pattern prevents which exploit when you're reviewing code at 2am before a mainnet deployment.

Smart Contract Security Skill

Master smart contract security with vulnerability detection, auditing methodology, and incident response procedures.

Quick Start

# Invoke this skill for security analysis
Skill("smart-contract-security", topic="vulnerabilities", severity="high")

Topics Covered

1. Common Vulnerabilities

Recognize and prevent:

  • Reentrancy: CEI pattern violation
  • Access Control: Missing modifiers
  • Oracle Manipulation: Flash loan attacks
  • Integer Issues: Precision loss

2. Auditing Methodology

Systematic review process:

  • Manual Review: Line-by-line analysis
  • Static Analysis: Automated tools
  • Fuzzing: Property-based testing
  • Formal Verification: Mathematical proofs

3. Security Tools

Essential tooling:

  • Slither: Fast static analysis
  • Mythril: Symbolic execution
  • Foundry: Fuzzing, invariants
  • Certora: Formal verification

4. Incident Response

Handle security events:

  • Triage: Assess severity
  • Mitigation: Emergency actions
  • Post-mortem: Root cause analysis
  • Disclosure: Responsible reporting
