## Findings

- **info** The word "credentials" in `check_medical_bill` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.bill_document.properties.url.description mentions "credentials".

inputSchema.properties.bill_document.properties.url.description: "...r a redirect, and so are links carrying credentials. At most 3 redirects, 12 MB, 20 seconds..."
```

- **info** The word "credentials" in `check_medical_bill` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.eob_document.properties.url.description mentions "credentials".

inputSchema.properties.eob_document.properties.url.description: "...r a redirect, and so are links carrying credentials. At most 3 redirects, 12 MB, 20 seconds..."
```

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

```untrusted-server-text
The server marks "check_medical_bill" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The description's first verb is "compare": a word for reading.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_case`

- The name "delete_case" says "delete": a word for removing or ending something.
- The description says "cannot be recovered".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete everything held about a case, immediately and permanently. The record is removed, not flagged, and it cannot be recovered afterwards — not by us either. This is the promise the privacy policy makes, and it needs no account. It does need the delete token issued when the case was created: reading a case and destroying it are deliberately different capabilities.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `unlock_case`

- The name "unlock_case" says "unlock": a word for a change.
- The description's first verb is "pay": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Pay to unlock the full findings, the dispute letter and the phone script. With a `shared_payment_token` (a Stripe Shared Payment Token granted to the `stripe_profile` in the case summary's `purchase`), it charges $10.00 for this bill and unlocks the case in the same call. Without one, it returns a checkout URL and charges nothing itself. A case with no findings is refused: there is nothing to buy, and the user pays nothing when nothing is found. So is a case with nothing to act on yet (`nothing_to_act_on`), such as a bill sent without its Explanation of Benefits whose only finding is that the EOB is missing.
```

## Changes things (3)

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

### `check_medical_bill`

- The description's first verb is "compare": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: info credentials-mention, info credentials-mention, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Compare a medical bill against the Explanation of Benefits the patient’s insurer issued for the same care, and report where the two disagree. Use when someone shares a medical bill, hospital statement, doctor bill, lab bill or EOB and asks whether it is correct, what they actually owe, or how to dispute it. The bill is required; the EOB is strongly recommended and is what makes most of the checks possible. If you can see the documents but cannot attach their bytes, transcribe them into `bill` and `eobs` exactly as printed. Free: returns a summary and the title of every finding, but not the detail behind them.
```

### `export_case`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Everything stored about a case, as JSON, in one response. This is the portable copy the privacy policy offers. It is deliberately the whole record rather than a summary, so that what is returned here can be compared against what the policy says is kept.
```

### `report_outcome`

- 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
Record what happened after the patient sent the dispute letter: corrected, reduced, refused, ignored, still waiting, or not sent. Free. Every answer counts equally, and it is kept only as an aggregate count — nothing about it is stored against the case. This product can tell that two documents disagreed; only these reports show whether saying so to a billing office changes anything.
```

## Only reads (2)

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

### `get_case`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve a case by id. Returns the same free summary, plus every finding in detail once the case has been unlocked.
```

### `get_case_outputs`

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

Description, as the server wrote it:

```untrusted-server-text
Get the dispute letter and the phone script for an unlocked case. The letter is a template the patient sends in their own name.
```
