Language-specific vulnerability hotspot reference for manual code audit. Trigger when the user asks to: "what sinks should I look for in Java?", "Python security hotspots", "dangerous functions in Go", "JavaScript injection patterns", or when starting a manual audit of a specific language and needing a sink/source checklist.
Deserialization vulnerability audit skill with gadget chain knowledge for all major languages. Trigger when the user asks to: "audit deserialization", "check for insecure deserialization", "find pickle vulnerabilities", "Marshal.load audit", "gadget chain analysis", "check for unsafe YAML loading", or when reviewing code that processes serialized data (JSON with type info, YAML, XML, binary formats).
Elite manual security code review skill for deep, adversarial vulnerability hunting and exploit-chain discovery. Trigger when the user asks to: "do a deep security audit", "manual code review", "find exploit chains", "hunt for logic bugs", "red-team this codebase", "do an offensive security review", "review this like a pentester", or needs a human-class manual code review that goes far beyond pattern matching. This skill operates as a top-tier offensive security engineer reading code line by line, tracing attacker-controlled data across trust boundaries, and proving exploitability before reporting. Complements eresus-sast-scanner with depth-first manual reasoning where the scanner provides breadth-first coverage.
Deep PHP-specific security audit skill covering injection, deserialization, file operations, auth bypass, POP chain discovery, and CMS-specific patterns. Trigger when auditing PHP code: "audit this PHP app", "find PHP security issues", "check Laravel/WordPress for vulnerabilities", "PHP SAST review", "check for PHP deserialization", "review this WordPress plugin". Includes scripts/rules.json for programmatic rule lookup.
Deep Python-specific security audit skill with 50+ vulnerability class coverage across 7 categories. Trigger when auditing Python code: "audit this Python app", "find Python security issues", "check Flask/Django for vulnerabilities", "Python SAST review", "check for pickle vulnerabilities", "review this FastAPI code". Covers misconfiguration, injection, crypto, XSS, deserialization, and ML/AI attack surfaces. Includes scripts/rules.json for programmatic rule lookup.
GHSA/CVE variant analysis workflow for finding similar vulnerability patterns across a codebase. Trigger when the user asks to: "find variants of this CVE", "GHSA variant analysis", "find similar bugs", "hunt for the same pattern", "are there other places with this vulnerability?", or when a known vulnerability is discovered and the user wants to know if the same pattern exists elsewhere.
Security-focused pull request and diff review skill for finding newly introduced vulnerabilities, risky regressions, and missing security tests in changed code. Trigger when the user asks to: "review this PR for security", "check this diff for vulns", "do a security code review", "audit changed files", or wants findings on a patch instead of a full-repo scan. Best used alongside eresus-sast-scanner.
Security remediation skill for fixing confirmed or likely SAST findings in source code. Trigger when the user asks to: "fix a vulnerability", "patch this security bug", "remediate SAST findings", "harden this endpoint", "make this auth flow safe", or wants code changes that remove a confirmed security issue while preserving intended behavior. Best used alongside eresus-sast-scanner.
