ai-19-adversarial-ml

ai-19-adversarial-ml is a skill for Claude Code, Codex from vigilantshield/Claude-HunterKit. It costs 31 tokens per session (366 once invoked), scanned C, original, no licence file.

A skill for working with adversarial machine learning, where inputs are deliberately changed to mislead or evade an AI model. It covers text obfuscation and attempts to bypass safety classifiers.

In plain words
What is it for?
Use it to study adversarial examples, input perturbations, model evasion, text obfuscation, and safety-classifier bypasses.
Why use it?
It helps address situations where small input changes can cause a model or safety check to behave incorrectly.

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

ai-19-adversarial-ml scanned grade C with 1 finding 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 10d 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.

Instruction-override phrasinghighPrompt injection

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.
