GroundTruth — subsurface scan QA & trade estimating
Two independent AI models read a GPR, locate or pipe scan and flag the do-not-core call.

Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟡read_scan(image_url, discipline, field_note)
Get an independent AI second opinion on a subsurface scan before anyone cores or digs. Send a public image URL of a GPR scan, a marked-up concrete slab photo, a utility-locate markup, a concrete radiograph, or a CCTV pipe frame. TWO different AI models read it independently — the second is prompted to refute the first — and you get back every located target with its hazard class (do-not-core / rebar / verify / clear), plus a QA flag when the two reads disagree. Advisory only: a certified technician must review and sign off before any cutting.

"type": "string",
"description": "Optional: what the technician said on site. Used as context for names and depths only — it can never clear a hazard the image shows."

}🟡draft_estimate(job_description, trade)
Turn a plain-English description of a trade job into a professional itemized bid — real materials by size, fittings, consumables and labor on its own line, at realistic US market prices. Built for one-truck electrical, plumbing, HVAC and general-contracting shops. This is GruntPay: the contractor normally speaks this into their phone. Returns the line items plus a link to brand it and send it to the customer.
Input Schema
{
"type": "object",
"properties": {
"job_description": {
"type": "string",
"description": "What the contractor did or will do, in plain words. e.g. \"Replaced the panel, 85 feet of conduit, 8 can lights, 16 hours.\""
},
"trade": {
"type": "string",
"description": "electrical, plumbing, hvac, or general. Defaults to general."
}
