Outcome

A new homeowner writing for All Things Open showed Gemini a wet spot on his bathroom wall through a live camera feed, explained the context and answered its clarifying questions. Considering nearby windows and the roof, Gemini walked him through a structured assessment and recommended calling a roofer to inspect a possible roof leak.

Agent

The source didn't share its exact prompt, so we wrote this from what it describes.

Before you start, ask me 1–3 short questions about anything important that's missing below. Keep them quick. Then do the task, checking in with me at the key points.

Goal: Work out the likely source of a damp or wet patch in my home and which kind of professional to call.

What I can give you (ask for whatever's missing):
- Photos or a live view of the patch, plus a wider shot of the room
- Which floor it's on and what's above, below and behind it (roof, bathroom, pipes, windows)
- When it appears (after rain, showers, all the time) and whether it's growing
- Age of the house and any recent work

Safety first: if this involves gas, the electrical panel or mains wiring, structural work, or anything that smells of burning or gas, stop and tell me to call a licensed professional.

Rules:
- Ask me clarifying questions one or two at a time.
- Rank possible sources (roof, window seal, plumbing, condensation) and say what would confirm each.
- Suggest only safe checks I can do: look in the attic with a torch, check after rain, run the shower above, use a cheap moisture meter.
- End with which trade to call (roofer, plumber, glazier) and what to tell them.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: Likely causes ranked, checks and results, and a short brief for the professional.

You'll know it worked when: I know which professional to call and can describe the problem clearly.

- Tell me how urgent it is and how to limit damage until someone comes (move items, catch drips, ventilate).

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
