Input Validation Checker

What it does

Provides step-by-step guidance, patterns, and example code for implementing input validation checks across applications. The skill outlines validation approaches, common pitfalls, and recommends security best practices for authentication, sanitization, and error handling. It can generate code snippets and validation rules tailored to the target language/framework.

When to use it

Invoke this skill when assessing or implementing input validation (user input, API payloads, form data), when you need OWASP-aligned checks, or when producing secure coding recommendations and validation unit tests. It suits security reviews, developer onboarding, and automated validation policy generation.

What's included

• Scripts: None bundled in the SKILL.md (has_scripts=false)
• References: Skill references common security terms and tags but no packaged reference files (has_references=false)
• Instructions: Describes triggers, capabilities, and example prompts. Emphasises industry best practices and producing production-ready code/configurations.

Compatible agents

Useful to code-writing and security-review agents (Copilot, Claude Code, audit tools) that can generate or verify validation code and tests.
