scanning-input-validation-practices

Category: Security  ·  Sub-category: red-team  ·  Last updated:
type:scanner
This skill enables Claude to automatically scan source code for potential input validation vulnerabilities. It identifies areas where user-supplied data is not properly sanitized or validated before being used in operations, which could lead to security exploits like SQL injection, cross-site scripting (XSS), or command injection. Use this skill when the user asks to "scan for input validation issues", "check input sanitization", "find potential XSS vulnerabilities", or similar requests related to securing user input. It is particularly useful during code reviews, security audits, and when hardening applications against common web vulnerabilities. The skill leverages the input-validation-scanner plugin to perform the analysis.

What this skill does

scanning-input-validation-practices is a community-contributed Claude Code skill in the red-team sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/input-validation-scanner/ and loads when your prompt matches the skill's trigger.

Who uses this skill

It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
