## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `calculate`

- The description's first verb is "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Run the SR&ED investment tax credit calculator calculator: Your expenditure limit (the 35% band); Expenditures earning the 35% rate; Credit at 35%; Expenditures earning the 15% basic rate. Missing inputs fall back to their documented defaults.
```

### `enquiry_fields`

- 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
Every field of the SR&ED Claim Calculator enquiry: key, label, type, whether required, help text and the allowed options where there are any. Pass answers to submit_enquiry keyed by field key.
```

### `submit_enquiry`

- The name "submit_enquiry" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submits an enquiry to SR&ED Claim Calculator — NOT a purchase, NOT a guaranteed quote. Step 1: call with the answers (keyed by field key from enquiry_fields) and consent=true; it validates and returns a summary, the consent line and a confirmation token — show the person the summary and the consent line. Step 2: only if the person agrees, call again with the same answers, consent=true and the confirmation token; the enquiry is then submitted, and the person receives an email with a link they must click before any provider sees it. Consent means the person has read and agreed to: "Send my contact details to up to three relevant SR&ED consultants or accountants, chosen by SR&ED Claim Calculator, who'll contact me directly. I'll be emailed each firm's name as my details go to it, and can stop any more firms getting them."
```

## Only reads (2)

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

### `calculator_describe`

- The name "calculator_describe" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The inputs this calculator takes (with units, ranges and defaults), the outputs it returns, and the assumptions and tables behind it.
```

### `enquiry_describe`

- The name "enquiry_describe" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read first. States plainly what submit_enquiry does on SR&ED Claim Calculator: it starts an enquiry with human providers who quote directly. Nothing is bought, ordered or paid; no quote is guaranteed; it is free. Also returns who receives the details, the consent wording, and how the person confirms.
```
