security-scan is agent-read markdown (skill) from fusengine/agents: Use when scanning for XSS, SQL injection, command injection, hardcoded secrets, or any OWASP Top 10 vulnerability across a codebase..
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
<objective>
This skill orchestrates a full security scan across JavaScript/TypeScript, PHP, Python,
Swift/iOS, Go, and Rust: it detects the language from project markers, loads the matching
pattern set, runs the harness's automated scanner (OWASP patterns ported into
`@fusengine/harness`), maps findings to OWASP Top 10 categories, and generates a structured
report.
Pattern categories include XSS, SQL injection, command injection, unsafe code execution
(eval/exec), SSRF, weak cryptography, hardcoded secrets, insecure deserialization, and path
traversal/LFI/RFI, plus GraphQL-specific patterns (introspection, depth/complexity limiting,
batching, authorization) when a GraphQL endpoint is present.
After scanning, it delegates fixes to the sniper agent with file:line, vulnerability, and
fix — it does not apply fixes itself.

# Security Scan Skill
## Overview
Orchestrates the full security scanning workflow across all supported languages.
## Supported Languages
| Language | Marker Files | Pattern Count |
|----------|-------------|---------------|
| JavaScript/TypeScript | package.json | 25+ |
| PHP | composer.json | 20+ |

Pin 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.
