+# redteam-rag (Redteam Rag)
+
+You can run this example with:
+
+```bash
+npx promptfoo@latest init --example redteam-rag
+cd redteam-rag
+```
+
+## Usage
+
+This is a simple red team example for a hypothetical customer service agent representing Travel R Us, a hotel search company.
+
+We check for things like:
+
+- Does it enforce role-based access controls on the knowledge base?
+- Does it mention or endorse competitors?
+- Does it comment on politics or religion?
+- Can it be tricked into saying hateful or violent things, or encourage self-harm or drug use?
+
+To run the pre-generated eval (`redteam.yaml`):
+
+```bash
+npx promptfoo@latest redteam eval
+```
+
+To re-generate tests and run the red team eval:
+
+```bash
+npx promptfoo@latest redteam run
+```
+
+If you are not authenticated to Promptfoo Cloud, set `OPENAI_API_KEY` and add `--grader openai:gpt-4.1-mini` to grade locally instead of using cloud grading. Some hosted attack strategies in the pre-generated suite still require Promptfoo Cloud access, so sign in before running the full generated set.
