## Findings

- **warn** Annotations that disagree with the tool in `request_cost_breakdown_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "request_cost_breakdown_link" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "request_cost_breakdown_link" says "request": a word for a change.
```


## Changes things (1)

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

### `request_cost_breakdown_link`

- The name "request_cost_breakdown_link" says "request": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns only the personal link (quoteRequestUrl) for one programme and family: the calculator page on goodbyematrix.com with the family already filled in, where the user requests the detailed cost breakdown with the exact amounts by e-mail from the GoodbyeMatrix team. The link carries the family only, never contact details; the user enters their contact details on that page, checks them and sends the request personally; the privacy consent is never preselected. Read-only: it returns a URL only; nothing is sent, booked or stored.
```

## Only reads (2)

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

### `get_cbi_quote`

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

Description, as the server wrote it:

```untrusted-server-text
Answers how much citizenship by investment or a second passport costs for a person or family, or compares programmes by total cost. Calculates the indicative cost for a family: government contribution, investment, fees, professional fees, payment phases and total in USD, plus which family members are eligible, processing time, page links and quoteRequestUrl. With one programme it returns that programme; without program it compares all 9 programmes (St Kitts and Nevis, Antigua and Barbuda, Dominica, Grenada, Saint Lucia, Vanuatu, Sao Tome and Principe, Nauru, Argentina). Nationality and country of birth count for every person in the family, not only for the main applicant. Figures are calculated live at request time from the current GoodbyeMatrix price and rule data; the data status is the date of the response (updatedAt), not an older date. Figures are rounded indicative figures (total to the nearest 1,000 USD), binding only after a pre-check; the user receives the exact amounts by requesting the cost breakdown through quoteRequestUrl. Read-only: it only retrieves and computes from the GoodbyeMatrix data set, stores nothing, sends nothing and calls no external services.
```

### `list_cbi_programs`

- The name "list_cbi_programs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
For questions about which citizenship by investment (second passport) programmes exist or what they start from: lists the 9 programmes GoodbyeMatrix prices (St Kitts and Nevis, Antigua and Barbuda, Dominica, Grenada, Saint Lucia, Vanuatu, Sao Tome and Principe, Nauru, Argentina) with region, route (contribution, investment or both), starting amount in USD for a single applicant, professional fee label, processing time, number of visa-free destinations where known, calculator and programme page links, and short notes. Read-only: it only retrieves and computes from the GoodbyeMatrix data set, stores nothing, sends nothing and calls no external services.
```
