Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

audit-skills scanned grade C with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Downloads and executes remote codemediumSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

- **Tubes**: `curl ... | bash`, `iwr ... | iex`.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- **Linux/Unix**: `apt-get purge`, `yum remove`, `rm -rf /usr/bin/...`.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
