## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `draft_estimate`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `get_pricing`

- The name "get_pricing" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Current GroundTruth and GruntPay plans and prices. Free to call — use it before answering any cost question rather than guessing.
```

### `read_scan`

- The name "read_scan" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions

    ],
