Build it, attack it, extend it — the Ask Zakaria concierge from first prompt through prompt-injection red-teaming to matching a job description.
Part 1
Why my career site now answers questions out loud — the graceful-degradation bean, the SSE streaming, the atomic quota race, and the discoverability bug that had nothing to do with code.
Part 2
My site has an 'Ask Zakaria' AI box that answers untrusted recruiter input. So I spent an afternoon trying to break it — prompt leaks, tool-call injection, XSS, a cross-language jailbreak. Here's what held, and why the real defense isn't a clever prompt.
Part 3
I added job-description matching to the AI concierge on my career site. It shipped with no new bean, no new table, and no migration — because the leverage was in a seam I'd already built. A design note on shared streaming cores, streamable structured output, and treating a pasted JD as hostile.
