Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.
Pinned to a commit: passed
Scanned openhands/skills at 9c140e285e.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill
What it does
This skill provides access to a suite of tools and techniques focused on cybersecurity. It allows AI agents to identify potential vulnerabilities, analyze security risks, and generate reports based on established security frameworks. The tool can also assist in crafting secure code by identifying common coding errors that could lead to exploits.
When to use it
- Vulnerability Assessment: When needing to evaluate a system or application for potential weaknesses before deployment.
- Security Auditing: To perform routine checks of existing infrastructure and identify areas for improvement.
- Secure Coding Practices: During software development to proactively prevent security flaws in code.
- Incident Response: When investigating a suspected security breach to determine the scope and impact.
Key capabilities
- Vulnerability identification
- Risk analysis
- Security report generation
- Secure coding assistance
Example prompts
- "Analyze this website for common vulnerabilities."
- "Generate a security audit report based on NIST standards for my web application."
- "Review this Python code snippet and identify potential security flaws."
Tips & gotchas
The skill’s effectiveness depends on the quality of input data; providing accurate system information is crucial. Results should always be reviewed by a human cybersecurity expert, as AI-generated assessments are not a substitute for professional judgment.
