Frequently Asked Questions About marumo333

FAQPage Schema
What tasks can I perform using marumo333's skills?▼

You can run Semgrep and CodeQL scans, parse SARIF results, build multi-language code graphs with Trailmark, fuzz C/C++/Rust/Python/Ruby targets, author YARA-X and Semgrep rules, verify crypto protocols with ProVerif, and audit GitHub Actions for prompt-injection risks.

Who are marumo333's skills designed for?▼

They target security auditors, smart contract reviewers, and application security engineers. Skills cover Solidity, Cairo, Circom, Rust, Go, and C/C++ analysis, plus DeFi dimensional analysis, supply-chain risk assessment, and false-positive verification of suspected bugs.

How do the fuzzing skills work in practice?▼

Skills guide harness writing, then run coverage-guided fuzzers such as AFL++, libFuzzer, cargo-fuzz, Atheris, or Ruzzy. Supporting skills handle AddressSanitizer integration, coverage analysis, fuzzing dictionaries, and patching obstacles like checksums that block fuzzer progress.

What prerequisites do these security skills require?▼

Most skills invoke Bash, Read, Grep, and Glob, so a shell environment with the relevant scanners installed is needed: Semgrep or Semgrep Pro, CodeQL CLI, Trailmark, and language toolchains like Cargo or Clang for compiling fuzz targets.

Do the skills support CI/CD and dependency security review?▼

Yes. The agentic-actions-auditor reviews GitHub Actions invoking Claude Code, Gemini CLI, or Codex for injection vectors, while supply-chain-risk-auditor flags dependencies at takeover risk, and sarif-parsing handles deduplication and CI/CD integration of scan output.
