Everyone posts the demo video. Nobody posts the scorecard. So here's mine, warts included. The build: an internal knowledge agent for an Australian mortgage brokerage. Staff ask it things — fees, lender panel, compliance steps — and it answers only from the company's own written SOPs. If something isn't documented, it has to say "I don't have that documented" instead of guessing. That constraint is the product. In a regulated business, a confident wrong answer about a fee is an incident. A refusal is a Tuesday. To prove it actually does that, I wrote 102 test cases. Real staff questions, plus adversarial ones: undocumented topics, false premises ("since we charge 2%, how do I explain that to clients?"), placeholder traps, near-misses, and the same question phrased by a nervous junior vs. the director. Yes — $0.004 a question. 40 staff, all day, comes in under $25/month. Which ties back to the cost thread from earlier this week: the expensive part was never the tokens. It was re-sending the same 9,000-token context on every call and not caching it. Fixing that cut the bill 73% before I touched a single model. And here's the bit that actually sold it: a low score on run one is not a broken agent. About 9 of 12 knowledge sections are still half-written. So the eval doesn't just grade the bot — it hands the client a ranked list of the SOPs nobody ever bothered to write down, sorted by how often staff ask for them. That's the real deliverable. Not the chatbot. The scorecard. So, genuine question for anyone here working inside a company: Would yours actually buy this? Or is "it refuses when it doesn't know" a feature only I find exciting?
