Built an AI-powered customer support chatbot for Fontty Games from the ground up.
Designed the system prompt architecture, intent scoping, and structured JSON output pipeline using the DeepSeek API. The assistant — Sir Alfonzo Quareno IV — handles game inquiries across three titles and escalates flagged cases (refunds, bug reports, collabs, and more) by collecting user data conversationally and logging it automatically to Google Sheets via a custom Apps Script webhook🔥.
Key engineering decisions:
Structured JSON output enforced via response_format to guarantee parseable replies
Stateless service with conversation history managed per session on the frontend
Escalation logic driven entirely by model output — no hardcoded UI triggers
Prompt designed to resist persona attacks, scope creep, and language confusion
Built on Blazor Server with MudBlazor for the frontend.

The fix for an agent that keeps getting your design system wrong isn't a better prompt.
It's putting the rules where the agent reads them.
In the repo. In skills. In checks it can run itself.
Writing a course about exactly this.
What sells it for me is the refusal telling the agent exactly where the token should go. A bare "no hex" error usually just sends it looping. Does guard.mjs run only as an agent hook, or in pre-commit too so it catches humans as well?

I'm not sure how long it'll stay at #1 as more creators start converting their templates, but it's exciting to see it there!
I'd pick Light for an analysis tool, the charts and sources read better on a pale surface and the violet bars still pop. Dark works as the night option. Is the sources panel on the right open by default?
