Audit Skills

Selective Reading Rule

Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.

Audit Skills (Premium Universal Security)

Overview

Expert security auditor for AI Skills and Bundles. Performs non-intrusive static analysis to identify malicious patterns, data leaks, system stability risks, and obfuscated payloads across Windows, macOS, Linux/Unix, and Mobile (Android/iOS). 2-4 sentences is perfect.

When to Use This Skill

• Use when you need to audit AI skills and bundles for security vulnerabilities
• Use when working with cross-platform security analysis
• Use when the user asks about verifying skill legitimacy or performing security reviews
• Use when scanning for mobile threats in AI skills

How It Works

Step 1: Static Analysis

Performs non-intrusive static analysis to identify malicious patterns, data leaks, system stability risks, and obfuscated payloads.

Step 2: Platform-Specific Threat Detection

Analyzes code for platform-specific security issues across Windows, macOS, Linux/Unix, and Mobile (Android/iOS).

1. Privilege, Ownership & Metadata Manipulation

• Elevated Access: sudo, chown, chmod, TakeOwnership, icacls, Set-ExecutionPolicy.
• Metadata Tampering: touch -t, setfile (macOS), attrib (Windows), Set-ItemProperty, chflags.
• Risk: Unauthorized access, masking activity, or making files immutable.

2. File/Folder Locking & Resource Denial

• Patterns: chmod 000, chattr +i (immutable), attrib +r +s +h, Deny ACEs in icacls.
• Global Actions: Locking or hiding folders in %USERPROFILE%, /Users/, or /etc/.
• Risk: Denial of service or data locking.

3. Script Execution & Batch Invocation

• Legacy/Batch Windows: .bat, .cmd, cmd.exe /c, vbs, cscript, wscript.
• Unix Shell: .sh, .bash, .zsh, chmod +x followed by execution.
• PowerShell: .ps1, powershell -ExecutionPolicy Bypass -File ....
• Hidden Flags: -WindowStyle Hidden, -w hidden, -noprofile.

4. Dangerous Install/Uninstall & System Changes

• Windows: msiexec /qn, choco uninstall, reg delete.
• Linux/Unix: apt-get purge, yum remove, rm -rf /usr/bin/....
• macOS: brew uninstall, deleting from /Applications.
• Risk: Removing security software or creating unmonitored installation paths.

5. Mobile Application & OS Security (Android/iOS)

• Android Tools: adb shell, pm install, am start, apktool, dex2jar, keytool.
• Android Files: Manipulation of AndroidManifest.xml (permissions), classes.dex, or strings.xml.
• iOS Tools: xcodebuild, codesign, security find-identity, fastlane, xcrun.
• iOS Files: Manipulation of Info.plist, Entitlements.plist, or Provisioning Profiles.
• Mobile Patterns: Jailbreak/Root detection bypasses, hardcoded API keys in mobile source, or sensitive permission requests (Camera, GPS, Contacts) in non-mobile skills.
• Risk: Malicious mobile package injection, credential theft from mobile builds, or device manipulation via ADB.

6. Information Disclosure & Network Exfiltration

• Patterns: curl, wget, Invoke-WebRequest, Invoke-RestMethod, scp, ftp, nc, socat.
• Sensible Data: .env, .ssh, cookies.sqlite, Keychains (macOS), Credentials (Windows), keystore (Android).
• Intranet: Scanning internal IPs or mapping local services.

7. Service, Process & Stability Manipulation

• Windows: Stop-Service, taskkill /f, sc.exe delete.
• Unix/Mac: kill -9, pkill, systemctl disable/stop, launchctl unload.
• Low-level: Direct disk access (dd), firmware/BIOS calls, kernel module management.

8. Obfuscation & Persistence

• Encoding: Base64, Hex, XOR loops, atob().
• Persistence: reg add (Run keys), schtasks, crontab, launchctl (macOS), systemd units.
• Tubes: curl ... | bash, iwr ... | iex.

9. Legitimacy & Scope (Universal)

• Registry Alignment: Cross-reference with CATALOG.md.
• Structural Integrity: Does it follow the standard repo layout?
• Healthy Scope: Does a "UI Design" skill need adb shell or sudo?

Step 3: Reporting

Generates a security report with a score (0-10), platform target identification, flagged actions, threat analysis, and mitigation recommendations.

Examples

Example 1: Security Review

"Perform a security audit on this skill bundle"

Example 2: Cross-Platform Threat Analysis

"Scan for mobile threats in this AI skill"

Best Practices

• ✅ Perform non-intrusive analysis
• ✅ Check for privilege escalation patterns
• ✅ Look for information disclosure vulnerabilities
• ✅ Analyze cross-platform threats
• ❌ Don't execute potentially malicious code during audit
• ❌ Don't modify the code being audited
• ❌ Don't ignore mobile-specific security concerns

Common Pitfalls

• Problem: Executing code during audit Solution: Stick to static analysis methods only

• Problem: Missing cross-platform threats Solution: Check for platform-specific security issues on all supported platforms

• Problem: Failing to detect obfuscated payloads Solution: Look for encoding patterns like Base64, Hex, XOR loops, and atob()

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
