## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "refund_eligibility" says "refund": a word that usually means money moves, which cannot be taken back.
```

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

```untrusted-server-text
The server marks "return_eligibility" 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 description's first verb is "evaluate": a word for a change.
```

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

```untrusted-server-text
The server marks "trial_terms" 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 description's first verb is "evaluate": a word for a change.
```


## Can't be undone (1)

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

### `refund_eligibility`

- The name "refund_eligibility" says "refund": a word that usually means money moves, which cannot be taken back.
- 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
Evaluate a US consumer subscription refund against versioned source-backed rules. Returns UNKNOWN when required conditions are absent or the vendor requires approval or manual policy review.
```

## Changes things (3)

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

### `cancellation_penalty`

- 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
Check US subscription cancellation terms without executing cancellation. Known vendors include review-only and retired scopes: their presence is not automation support. Adobe requires manual contract review. Typeform requires Basic, direct/self-serve platform scope and returns CANCEL_AT_PERIOD_END, not an immediate cancellation or refund. Missing scope, retired sources or unavailable current evidence return UNKNOWN.
```

### `return_eligibility`

- The description's first verb is "evaluate": 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
Evaluate whether a US consumer subscription purchase can be reversed under versioned source-backed rules. Returns UNKNOWN when required conditions are absent or manual review is required.
```

### `trial_terms`

- The description's first verb is "evaluate": 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
Evaluate a live US consumer subscription trial offer. Supply observed availability, duration, card, and auto-conversion facts; the tool returns UNKNOWN instead of inferring current offers from static data.
```
