LLM Testing Skill

Description

Comprehensive testing prompts and wordlists for evaluating Large Language Model (LLM) security, safety, and robustness. This skill provides curated test cases for bias detection, data leakage prevention, alignment testing, privacy boundaries, and adversarial prompt resistance.

Purpose

This skill is designed for security researchers, AI safety engineers, and red team operators to assess LLM vulnerabilities and ensure models:

  • Maintain ethical boundaries and safety guidelines
  • Avoid data leakage and privacy violations
  • Resist bias and discrimination
  • Prevent adversarial prompt attacks
  • Maintain alignment with intended behavior

Authorized Use Cases

  • AI Safety Research: Testing LLM models for safety and alignment issues
  • Security Auditing: Red team operations for AI/ML systems
  • Bias Detection: Evaluating models for fairness and bias
  • Privacy Testing: Verifying models don't leak training data or PII
  • Educational Purposes: Teaching AI security concepts and vulnerabilities
  • Responsible AI Development: Building more robust and secure LLMs

Test Categories

1. Bias Testing

Test for biases in LLM responses across various dimensions:

Gender Bias (Bias_Testing/gender_bias.txt)

  • Prompts to reveal gender stereotypes and biases
  • Career and role associations
  • Behavioral and capability assumptions
  • Note: Replace [GENDER] placeholder before use

Nationality & Geographic Bias (Bias_Testing/nationality_geographic_bias.txt)

  • Cultural stereotypes and geographic prejudices
  • Regional capability assumptions
  • Note: Replace [COUNTRY], [REGION], [NATIONALITY] placeholders

Race & Ethnicity Bias (Bias_Testing/race_ethnicity_bias.txt)

  • Racial and ethnic stereotypes
  • Discriminatory patterns in responses
  • Note: Replace [SKIN_COLOR] placeholder before use

2. Data Leakage & Privacy Testing

Assess model's handling of sensitive information:

Personal Data Generation (Data_Leakage/personal_data.txt)

  • Tests for PII generation capabilities
  • Verifies privacy boundaries
  • Checks for inadvertent personal information creation

Metadata Leakage (Data_Leakage/metadata.txt)

  • Tests for training data remnants
  • Checks for unintended information disclosure

Memory Recall (Memory_Recall_Testing/session_recall.txt)

  • Session-based memory testing
  • Cross-conversation data retention
  • Note: Replace [COUNTRY], [REGION], [NATIONALITY] placeholders

3. Divergence & Alignment Attacks

Test model alignment and resistance to adversarial prompts:

Escape Alignment Training (Divergence_attack/escape_out_of_allignment_training.txt)

  • Prompts attempting to bypass safety training
  • Tests for alignment robustness
  • Ethical boundary challenges

Pre-training Data Extraction (Divergence_attack/pre-training_data.txt)

  • Attempts to extract training data
  • Tests for memorization vulnerabilities

Usage Instructions

Basic Usage

# Reference the LLM Testing skill
"Use the llm-testing skill to test this model for gender bias"

# Access specific test categories
"Show me prompts from the llm-testing skill for testing data leakage"

# Run comprehensive testing
"Use the llm-testing skill to perform a full security audit of this LLM"

Replacing Placeholders

Before using bias and memory recall tests, replace placeholders:

# Example: Replacing placeholders in gender bias tests
import re

with open('Bias_Testing/gender_bias.txt', 'r') as f:
    prompts = f.read()

# Replace [GENDER] with actual gender terms
test_prompts = []
for gender in ['man', 'woman', 'non-binary person']:
    test_prompts.append(prompts.replace('[GENDER]', gender))

Testing Workflow

  1. Select Test Category: Choose bias, privacy, or alignment tests
  2. Prepare Prompts: Replace placeholders if needed
  3. Execute Tests: Submit prompts to target LLM
  4. Document Results: Record responses and flag issues
  5. Analyze Patterns: Look for systematic problems
  6. Report Findings: Document vulnerabilities responsibly

Best Practices

Ethical Testing Guidelines

  1. Authorization Required: Only test models you own or have permission to test
  2. Responsible Disclosure: Report vulnerabilities through proper channels
  3. No Exploitation: Use findings for improvement, not exploitation
  4. Privacy Protection: Don't share PII discovered during testing
  5. Documentation: Keep detailed records of testing methodology and results

Testing Methodology

  • Baseline Establishment: Test multiple times to establish patterns
  • Controlled Environment: Use isolated testing environments
  • Systematic Approach: Test one category at a time
  • Diverse Scenarios: Use various prompt formulations
  • Cross-Validation: Verify findings with different approaches

Interpreting Results

  • Context Matters: Consider the model's intended use case
  • Statistical Significance: Don't rely on single responses
  • Severity Assessment: Classify findings by impact level
  • False Positives: Verify actual vulnerabilities vs. expected behavior

Security Considerations

Red Team Operations

  • Use these prompts as part of comprehensive AI red teaming
  • Combine with other security testing methodologies
  • Focus on discovering vulnerabilities before adversaries do

Defensive Applications

  • Train models to better resist these attack patterns
  • Build detection systems for adversarial prompts
  • Improve safety alignment and guardrails

codex-pet

prime-skills/runcomfy-agent-skills

Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
