FAQ

How do I scan untrusted text for prompt injection before an LLM call?
Use Skillware security/prompt_injection_firewall — pip install "skillware[security_prompt_injection_firewall]", load the skill, pass source_text; it returns is_safe, findings, and optional sanitized_text locally.
Does the firewall call an LLM to audit content?
No. It is pattern-based and deterministic — no network, no API keys, no auditing model in the loop.
