From the author

OWASP Top 10 for Web Applications (2025) knowledge base for identifying, assessing, and remediating web application security risks.

— the description by Microsoft

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a machine-readable implementation of the OWASP Top 10 for Web Applications (2025). It serves as a comprehensive reference for developers and security professionals to understand, detect, and mitigate critical web vulnerabilities. Each of the ten vulnerability categories is documented with detailed descriptions, risk assessments, checklists for identifying exposure, and actionable prevention controls.

What it does

Provides structured access to the 2025 OWASP Top 10 web security vulnerabilities.
Offers vulnerability-specific checklists to help identify potential security gaps.
Includes detailed prevention controls and remediation strategies for each risk.
Supplies clear descriptions of how vulnerabilities manifest in modern web applications.
Categorizes risks by their primary security domain, such as Access Control or Cryptography.
Enables agents to perform security-focused analysis and provide guidance on hardening applications.

When to use it

During the design phase to ensure security best practices are built into the architecture.
When performing security audits or code reviews to identify common vulnerability patterns.
When remediating specific security findings reported by automated scanners or penetration tests.
To educate development teams on the most critical risks facing web applications today.

Advantages

Standardized, machine-readable format allows for easy integration into agent workflows.
Covers the most critical and pervasive web application security risks.
Provides actionable, concrete steps for both detection and long-term remediation.
Aligned with the industry-standard OWASP framework for consistency in security reporting.

Usage examples

“What are the common indicators that my application is vulnerable to broken access control?”: The agent will return a checklist of indicators, such as the ability to bypass access controls via URL tampering or missing authorization on API endpoints.
“How can I prevent cryptographic failures in my web application?”: The agent will provide specific prevention controls, such as enforcing strong encryption standards and managing keys securely.
