# Prompt Injection Tester
## Purpose / Amaç
Drive a repeatable, evidence-based prompt-injection assessment against a target LLM
application and produce a scored report. The skill covers **direct** injection (attacker
text arrives in the user turn) and **indirect** injection (attacker text arrives through
retrieved documents, tool output, web pages, file contents, or email the model ingests).
It is bilingual by design: Turkish-language payloads routinely bypass English-only guardrails,
so every family is tested in both English and Turkish.
The output is not "the model said something bad." It is: **which family bypassed which control,
with which evidence, at what severity, mapped to OWASP LLM01 and ATLAS** — plus an over-refusal
measurement so a defense that simply blocks everything does not score as "secure."
## When to use
Use this skill when the task is any of:
- "Test / audit / pentest this chatbot (or agent, or RAG system, or `/chat` endpoint) for prompt injection."
- "Can someone leak our system prompt / exfiltrate the canary / override our instructions?"
- "We added a guardrail — prove whether it actually blocks injection without over-blocking."
- "Check our tool-using agent for excessive agency triggered by injected instructions."
Do **not** use this skill to attack a system the operator has not authorized (see Limits & ethics).
## Prerequisites & scope (do this first)
1. **Confirm authorization.** You must have explicit permission to test the target. Record the
