Prompt-Injection Hardening for a Customer-Support Agent. Advanced challenge in code. Writing production code that solves real engineering problems, earn a bl...
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.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
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
