evaluating-enhancing-vulnerability-reasoning SKILL.md skillA
evaluating-enhancing-vulnerability-reasoning from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/evaluating-enhancing-vulnerability-reasoning@git:20261102.b4557fdPins git:20261102.b4557fd in mdr.lock. Pin the fingerprint instead.

Perform DAG-structured vulnerability reasoning on code, modeling causal dependencies between code facts instead of linear chain-of-thought. Use when asked to: 'analyze this code for vulnerabilities', 'explain why this code is vulnerable', 'trace the root cause of this security bug', 'review this function for memory safety issues', 'is this code exploitable and why', 'reason about the security of this code path'.
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
# DAG-Structured Vulnerability Reasoning This skill enables Claude to perform rigorous vulnerability analysis using Directed Acyclic Graph (DAG) structured reasoning, based on the DAGVul framework. Instead of producing linear chain-of-thought explanations that often hallucinate plausible-sounding but incorrect logic, this approach models vulnerability reasoning as a graph of causal dependencies: extracting ground facts from code as source nodes, building intermediate inference nodes through taint tracking and control/data flow analysis, and converging on terminal sink nodes that confirm or refute the vulnerability. This enforces structural consistency and eliminates the 12 systematic failure patterns (hallucination, spurious causality, incomplete evidence, etc.) that plague standard LLM vulnerability analysis. ## When to Use - When a user asks to analyze code for security vulnerabilities and wants to understand the root cause, not just a yes/no verdict - When reviewing a function or module for memory safety issues (use-after-free, buffer overflow, null pointer dereference) …

How to install
mdr add lu1sdv/skillsmd/evaluating-enhancing-vulnerability-reasoning@sha256:3db256fb9d44bf30The line at the top of this page pins the label git:20261102.b4557fd, 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.
