    About this skill

    Secure Your Agent Pipeline

    As AI agent ecosystems grow, the risks of "malicious skills" increase. The Skill Safety Scanner is a developer-centric security tool designed to audit SKILL.md files for risky instructions, hidden behaviors, and potential prompt injections before you integrate them into your environment.

    What it does

    The scanner performs a deep static analysis of skill definitions to identify high-risk patterns that could compromise your system. It flags specific categories of concern including:

    • Unauthorized Exfiltration: Detects suspicious data transfer or network instructions.
    • Privilege Escalation: Identities broad local file access and shell execution requests.
    • Hidden Behaviors: Surfaces obfuscated hints, persistence mechanisms, and unbounded autonomy.
    • Social Engineering: Flags prompt injection wording and credential harvesting attempts.

    Why use this skill?

    Unlike basic keyword searching, this skill understands the context of agent instructions. It provides a structured safety report (Terminal, JSON, or Markdown) that allows you to automate security gates in your CI/CD pipeline or manually vet third-party skills with confidence. Crucially, it runs entirely locally with zero network calls, ensuring your proprietary code and skill definitions never leave your machine.

    • Static analysis only; cannot detect risks in runtime-generated dynamic prompts.
    • Limited to scanning SKILL.md files.

    Frequently Asked Questions

    The Skill Safety Scanner analyzes the instructions within an agent's skill definition files to identify risks like prompt injections, unauthorized data exfiltration, and hidden persistence mechanisms before you deploy them.

    This is a language-agnostic static analysis tool that works with any AI agent framework that uses text-based skill definitions, such as SKILL.md files or standard JSON/YAML configuration formats.

    Security is a priority; the scanner performs all analysis entirely on your local machine with zero external API calls, ensuring your skill definitions and proprietary instructions are never exposed to the cloud.

    The scanner provides structured output in Terminal (CLI), JSON, or Markdown formats, making it easy to integrate as an automated security gate within your existing CI/CD pipelines or GitHub Actions.

    Your purchase includes the full Skill Safety Scanner package, a comprehensive user guide, and access to future updates that include new detection patterns as emerging AI threats are discovered.
