Prompt-Injection Hardening for a Customer-Support Agent

FreeVerified credential2 weeksAdvanced

Overview

What this challenge is about.

Redesign a consumer AI agent prompt to block 60 injection attacks at 97% success. Earn a verifiable certificate.

The scenario

The startup (Series B, around 90 staff, around 8M monthly active users) needs to clear a SOC 2 attestation in the next quarter; an unmitigated prompt-injection finding would block the audit.

The Brief

What you'll do, and what you'll demonstrate.

Harden a support-agent's prompt stack against direct and indirect prompt injection while preserving benign answer quality.

Earning criteria — what you'll demonstrate

  • Distinguish direct and indirect prompt-injection attack patterns
  • Apply structured-delimiter and input-scanning defenses in a prompt stack
  • Run a red-team eval and report findings honestly
  • Translate prompt-security work into language a security team can sign off on

This challenge maps to Prompt Engineering at the Master level. It sharpens the same practical skills your coursework expects — but in a real industry context with actual constraints and deliverables.

Careers

Career paths this challenge builds toward

Completing this challenge demonstrates skills that transfer directly to these roles:

AI Safety Researcher

Hardening a deployed agent against prompt injection with a red-team eval is the exact entry-level work AI safety researchers do at consumer AI companies.

This challenge sharpens

  • prompt-injection-defense
  • red-teaming
  • security-mindset

Prompt Engineer

Owning the system prompt + delimiter design and proving it with a red-team set is core prompt-engineer territory in any production deployment.

This challenge sharpens

  • system-prompt-design
  • prompt-evaluation
  • input-validation

AI Engineer

Defense-in-depth around a model API plus a regression-aware eval harness is the kind of glue AI engineers ship.

This challenge sharpens

  • input-validation
  • prompt-evaluation
  • system-prompt-design
