# Prompt Injection Detector Skill ## Capabilities - Detect prompt injection attempts - Implement input sanitization - Configure detection classifiers - Design defense layers - Implement canary token detection - Create injection logging and alerting ## Target Processes - prompt-injection-defense - tool-safety-validation ## Implementation Details ### Detection Methods 1. **Pattern Matching**: Known injection patterns 2. **ML Classifiers**: Trained injection detectors 3. **Canary Tokens**: Detect instruction override 4. **LLM-Based**: Use LLM to detect manipulation 5. **Perplexity Analysis**: Unusual input patterns ### Defense Strategies - Input preprocessing - Prompt structure design - Output validation - Sandboxed execution - Multi-layer defense ### Configuration Options - Detection threshold - Pattern rules - Classifier model - Action policies - Alerting settings ### Best Practices - Defense in depth - Regular pattern updates - Monitor false positives - Test with red-team inputs ### Dependencies - rebuff (optional) - transformers - Custom classifiers
