What sits below the water

Finds the belongings, appliances, outlets and utilities in the rooms that flood, how high each sits off the floor, and what the water would cost, as a range.

What it answers

• What would I lose at two feet of water?
• Is the water heater high enough?

For the agent, the tool is described as: Inventory the rooms that can flood in one scanned house from its panoramas (vision model, cached), with each item’s height off the floor, replacement-cost class and whether a person can carry it; electrical panel, water heater, furnace, washer, dryer and low outlets with heights. Totals the loss at the flood scenario as a low-high range. Pins every item.

Who it is for

Emergency manager or caseworker before a storm, Houston homeowner before a storm, Insurance underwriter.

Inputs

Input	Type	Required	Default	Notes
scan	string	yes		Scan id. Filled from the selected building.
depth_m	number (m)	yes		Water above the ground outside. Asked as: “How deep could the water get above the ground outside your house, in metres? Use a storm-surge forecast (given as height above ground) or a street-flooding depth.” Saved preference flood.depth_m. Range: at least 0, at most 3.
scenario	string		"depth"	Where the depth comes from: typed depth, storm surge, rainfall, or Harvey 2017 from USGS high-water marks (then depth_m is not used). Saved preference flood.scenario. One of: depth, surge, rainfall, harvey_2017.
floor_height_m	number (m)			Floor height above the ground at the door, if you measured it. Saved preference flood.floor_height_m.
use_drone	boolean		true	Measure the door threshold in the drone photos (vision model, cached).
max_rooms	integer		8	Most rooms to read with the vision model. Range: at least 1, at most 12.

An input that nothing fills (the selected building, a saved preference, a persona’s preset) becomes a question to the person. The agent asks only for those.

Data used

Layer	Id	Needed	If it is missing
360° photos	matterport.panoramas	required	The verdict is unknown, with the reason.
Rooms	matterport.rooms	required	The verdict is unknown, with the reason.
Empty-room photos	matterport.defurnished	optional	The tool runs without it.

What it returns

A tool result: a verdict (pass, warn, fail or unknown), metrics, checks and findings, each with its source.

• Draws on the building: pins on what it found; a water level.
• Panel blocks: VerdictHeader, MetricRow, Controls, CheckList, EvidenceStrip, FloorPlanMini, AssumptionChips, StepLog, ActionBar.
• Speed: slow. Read-only.

How it works

Valuables height: what sits below the water line, from the panoramas, with heights off the floor and a loss range.

Reliability

Every metric and finding carries its layer, its method and a high, medium or low label, set by the tool for each value. See findings and reliability.

Limits

• Needs: 360° photos, rooms. On a scan without them, the verdict is unknown and says why.
• The agent asks before running it, because it reads the panoramas of every room that floods with the vision model.
• It is slow: progress steps reach the workspace while it runs.
• A result is a planning aid, not an inspection.

On the made-up test home

This section was written by running the tool when the docs were built, on a hand-made RoomPlan export (no real place was scanned), with no sponsor keys and the network switched off.

Inputs used: depth_m = 0.6 (an answer given for this example).

Unknown No room that can take water has a panorama.

What it reported while it ran:

1. The scan has no location, so the aerial and drone methods are off
2. Scan outdoor panoramas: none near an exterior door
3. Water levels in the scan: lo +0.10 m from the entry floor, mid +0.30 m from the entry floor, hi +0.50 m from the entry floor

Run it

threshold run valuables_height --scan <scan-id>
curl -X POST http://127.0.0.1:8787/api/tools/valuables_height/run -H 'content-type: application/json' -d '{...inputs}'

Over MCP the tool is named valuables_height. See MCP server and CLI.
