find-security-vulnerabilities-in-code skillA
find-security-vulnerabilities-in-code is agent-read markdown (skill) from usestrix/strix: Find security vulnerabilities in a codebase or repository with Strix — a white-box AI security review that reads your source, reasons about the actual data flow and authorization model, then exploits what it finds in a live sandbox so every reported issue has a working proof-of-concept instead of a noisy static-analysis alert. Covers injection, XSS, SSRF, broken access control and IDOR, insecure deserialization, secrets in code, unsafe dependencies, and business-logic flaws. Use when the user as.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Find security vulnerabilities in code White-box security review with Strix: the agents read the source to build a model of routes, sinks, and authorization checks, then attempt real exploitation. Findings come with a proof-of-concept, so the output is a short list of proven issues rather than the hundreds of "potential" hits a pattern-matching scanner produces. Install, LLM setup, all flags, and the managed-cloud path are in the **penetration-testing-with-strix** skill. For a run with no Docker and no LLM key, the same binary drives the managed platform: `strix cloud login`, then `strix cloud scans start ...` (details in **managed-pentesting-with-strix**). ## Run it ```bash # Local working tree strix -n -t ./ --scan-mode standard --max-budget 15 # A GitHub repo directly strix -n -t https://github.com/org/app --max-budget 15 # Monorepo: point at the service that matters, not the whole tree strix -n -t ./services/checkout --max-budget 20 # Only what a branch changed (whole-repo review is wasteful on a large repo) strix -n -t ./ --scope-mode diff --diff-base origin/main --max-budget 10 ``` …

How to install
mdr add usestrix/strix/find-security-vulnerabilities-in-code@git:20260901.42baa7cmdr add usestrix/strix/find-security-vulnerabilities-in-code@sha256:e7c25f1a0aea437dPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
