Automated safety checks

scanned 12 Oct 2026

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 jeffallan/claude-skills at 1be15d8064.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The secure-code-guardian skill helps identify and mitigate security vulnerabilities in code. It scans for common issues like SQL injection, XSS (cross-site scripting), insecure dependencies, and misconfigurations, providing actionable recommendations to improve code safety.

When to use it

Before deploying a web application to production
When reviewing third-party libraries or code contributions
During regular code audits or security testing phases

Key capabilities

Detects common security vulnerabilities in code
Analyzes dependencies for known exploits or outdated packages
Provides remediation suggestions for identified issues
Integrates with code review workflows and CI/CD pipelines

Example prompts

"Scan this Python script for SQL injection risks"
"Check my JavaScript code for XSS vulnerabilities"
"Analyze the project's dependencies for security issues"

Tips & gotchas

Ensure your codebase is up to date before running scans for accurate results.
While it identifies potential issues, manual review is still recommended for critical applications.
