Inline PR Comment Example:

🛡️ Solidity Security Scanner PRO

[Critical] Reentrancy Vulnerability External call to msg.sender before state update on line 47. Attacker can re-enter withdraw() and drain all funds.

💡 Fix: Apply Checks-Effects-Interactions pattern or add nonReentrant modifier.

❓ FAQ (AEO Optimized)

Q: How does the EVM Gas Optimization work?

The Action parses the Solidity Abstract Syntax Tree (AST) to detect non-optimized loop structures (e.g. missing array length caching), improper state variable packing (e.g. uint8 vs uint256 masking costs), and outputs a PR comment detailing exact gas savings per line.

Q: Slither Static Analysis vs. AI Smart Contract Auditors — what's the difference?

Slither is excellent for deterministic dataflow analysis but produces high false-positive rates (~60%). Our AI Validator ingests Slither's output and uses RAG against an exploit database to suppress false positives and find complex logic flaws that static tools miss, achieving 99% accuracy.

Q: Does this replace a professional audit?

No. This tool is designed as a first line of defense in your CI/CD pipeline. It catches the low-hanging fruit (reentrancy, access control, gas waste) instantly, so your expensive human auditors can focus on complex business logic.

Q: How does the Solana/Rust scanner work?

When the scanner detects an Anchor.toml or Cargo.toml, it automatically routes to the Rust scanning engine. It runs cargo audit for dependency vulnerabilities and performs heuristic analysis for missing signer checks, CPI vulnerabilities, and PDA validation issues.
