description	Comprehensive security audit skill for NEAR Protocol smart contracts written in Rust. Use when auditing NEAR contracts, reviewing security vulnerabilities, or analyzing contract code for issues like reentrancy, unhandled promises, unsafe math, access control flaws, and callback security.

NEAR Contract Audit

Security audit skill for NEAR smart contracts in Rust.

Audit Workflow

Phase 1: Automated Analysis

Run your preferred Rust static analysis and NEAR-focused security tools on the contract to:

• Scan for common vulnerability patterns (reentrancy, unsafe math, unhandled promises, access control issues, etc.)
• Highlight potentially risky patterns for deeper manual review

Phase 2: Manual Review

After automated analysis, perform manual review for:

• Business logic vulnerabilities
• Access control patterns
• Economic attack vectors
• Cross-contract interaction safety

Phase 3: Code-Specific Analysis

For each finding, verify:

1. Is it a true positive?
2. What is the exploitability?
3. What is the recommended fix?

Phase 4: Report Generation

Document findings with severity, location, description, and remediation.
