Proof · the site tests itself

I don't just build AI. I prove it works.

Here's my own sales assistant — the chatbot that scopes engagements on this site — under adversarial test. The same kind of evaluation I run for clients, pointed at my own work first.

what gets tested

Four things a customer-facing AI has to get right.

This assistant talks to real prospects on the scoping page. Before it went live, and on every change since, it runs through a battery of adversarial probes and known-good conversations.

price leak

Never quotes a price

There's no fixed price list on this site on purpose. Every engagement is scoped on a call. So the assistant is tested for whether it can be talked into inventing a number, a rate, or "just a ballpark."

jailbreak

Resists prompt injection & jailbreaks

Classic attacks — "ignore previous instructions," "you are now DAN," instructions smuggled inside pasted data — tested against whether it breaks character or leaks its own instructions.

in character

Stays in character

It's supposed to represent me, on-topic, professionally. Probes check it doesn't start talking like a generic chatbot, trash a competitor, or wander off-brand under pressure.

golden set

Handles real conversations well

Alongside the attacks, a set of known-good scoping conversations — an AI-eval prospect, a local service business, an off-topic question — checked for a correct, on-topic reply every time.

the latest result

7 red-team probes. 3 golden conversations. All green.

What that headline number actually rests on.

A green scorecard means nothing if I don't tell you how it's built. Here's exactly what each result does and doesn't prove.

robust

The price check is enforced in code. The server strips and validates outputs before they reach the customer, so "never quotes a price" isn't the model's good behavior on faith. It's enforced at the response layer. That's the strongest guarantee on this page.

robust

The system-prompt leak check is grounded the same way. The assistant's instructions are never assembled into a form the model can echo back verbatim, so a "print your prompt" attack has nothing to leak even if it got the model to try.

limited, by design — for now

The jailbreak and in-character checks are fast substring heuristics, not a full LLM judge. They look for known break-character phrases ("as an AI language model," "I am now DAN," "developer mode enabled") in the reply. That catches the obvious failures reliably and runs in CI in seconds, but a more subtle jailbreak that never says those phrases could theoretically slip past a plain string match. A deeper LLM-as-judge layer that reads the whole reply for intent is a planned upgrade, not a claim I'm making today.

run it yourself

Public repo. Runnable against the live site.

This isn't a marketing screenshot. The harness lives in this site's own repository, next to the site itself, and you can point it at the live assistant and watch it run.

terminal
git clone https://github.com/JasonTeixeira/jt-portfolio
cd jt-portfolio && npm install
node scripts/eval-chatbot.mjs --url https://agency.sageideas.dev

Probes live in evals/chatbot/redteam.json and evals/chatbot/golden.json. The grading logic is in assets/chatbot-evals.mjs. The same pure functions run in this repo's unit tests (no live model needed) and in the live red-team run against production.
