InjectionShield is a lightweight, deterministic Python module that acts as a gate in front of AI agents to block prompt injection attacks. It uses rule-based detection on untrusted inputs such as emails or tool outputs, produces measurable error rates on labeled test sets, and requires no network, API, or ML model. The accompanying guide walks users through building, testing, and evaluating the filter with safe and malicious prompt corpora.
