vulnerability-analysis SKILL.md skillA
vulnerability-analysis from hypnguyen1209/offensive-claude is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hypnguyen1209/offensive-claude/vulnerability-analysis@git:20260630.f651559Pins git:20260630.f651559 in mdr.lock. Pin the fingerprint instead.

Use when auditing source code for vulnerabilities — drive CodeQL/Semgrep/Joern to taint untrusted data source-to-sink across injection, memory safety, deserialization/prototype-pollution, secrets/crypto/authz/race, and supply-chain risks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Vulnerability Analysis Every vulnerability you miss is one an attacker finds first. Systematic source auditing traces untrusted data from **source** to **sink**, evaluates every sanitizer for bypass, and questions each trust-boundary assumption. This skill is the router; depth lives in `references/`, and every technique cluster is backed by a runnable tool in `scripts/`. ## When to Activate - Auditing any codebase (white/grey box) for security vulnerabilities - Writing/driving CodeQL queries, Semgrep taint rules, or Joern CPGQL flows - Tracing injection, deserialization, prototype-pollution, or memory-safety paths - Reviewing auth/authorization (IDOR/BOLA), cryptography, or concurrency (TOCTOU) - Triaging dependency CVEs and hunting malicious/compromised packages (SCA) - Variant hunting — generalizing one finding into a codebase-wide pattern ## Technique Map | Technique | ATT&CK | CWE | Reference | Script | |-----------|--------|-----|-----------|--------| | Taint analysis (source/sink/sanitizer modeling) | T1190 | CWE-20 | references/taint-engines-static-analysis.md | scripts/taint_trace.py | …

How to install
mdr add hypnguyen1209/offensive-claude/vulnerability-analysis@sha256:606092f86af1cda6The line at the top of this page pins the label git:20260630.f651559, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
