Evaluating Prompt Injection Risks in Small-Business AI Assistants
A controlled comparison of defensive design choices for AI assistants that read untrusted content and can take actions, such as answering customer email or updating records.
- Build a local test assistant that operates only on synthetic business data.
- Run the same injection test suite against a baseline and against each defensive configuration.
- Compare input separation, tool permission restrictions, output validation, human approval steps and retrieval trust boundaries.
- Score every outcome against a published rubric so results can be reproduced and challenged.
- Test cases and scoring rubric
- Results tables with limitations
- Reproducible test harness on GitHub
- Practical recommendations for small teams
