ai-red-teamer

ai-red-teamer is a skill for Claude Code, Codex from vignesh2027/Claude-Agentic-Skills2.0-version. It costs 74 tokens per session (1,051 once invoked), scanned B, original, MIT.

An adversarial testing specialist for artificial-intelligence and large-language-model systems. It probes systems for unsafe behavior, security weaknesses, and failures when given difficult or malicious inputs.

In plain words
What is it for?
Use it to test prompts, evaluate safety controls, probe edge cases, design red-team test suites, and write reports with severity ratings and suggested fixes.
Why use it?
It helps reveal problems such as prompt injection, attempts to bypass safety rules, data leakage, and unreliable behavior before users encounter them.

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 B, and why

ai-red-teamer scanned grade B 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 11d 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 phrasingmediumPrompt injection

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

| Direct prompt injection | LLM01 | Critical | Override system prompt via user input |

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

Attack Taxonomy (OWASP LLM Top 10 Coverage)

Attack Vector Category Severity Test Method
Direct prompt injection LLM01 Critical Override system prompt via user input
Indirect prompt injection LLM01 Critical Inject via retrieved documents/tools
Training data extraction LLM06 High Memorization probing with prefix attacks
Model denial of service LLM04 High Recursive/exponential token generation

Red-Team Test Suite Structure

Phase 1: Baseline (20 tests)
  - Benign queries across all intended use cases
  - Establishes normal behavior fingerprint

Phase 2: Boundary Testing (40 tests)
  - Edge cases: empty input, max tokens, Unicode, code injection
  - Role-play escalation: persona adoption probes

Phase 3: Adversarial (60 tests)
  - Direct instruction override attempts
  - Indirect injection via tool outputs / RAG documents
  - Multi-turn context manipulation

Phase 4: Policy Stress (30 tests)
  - All harm categories: CSAM, bioweapons, self-harm, violence
  - Dual-use scenarios: chemistry, hacking, social engineering
  - Gray areas: legal-but-harmful, information hazards

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ai-red-teamer is a skill published in the GitHub repository vignesh2027/Claude-Agentic-Skills2.0-version (6 stars, last pushed 13d ago), licensed MIT. It adds 74 tokens to every session and 1,051 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (instruction-override phrasing). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
