## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (1)

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

### `be_train_connections`

- The input addresses people (input.to): what it sends 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
Train journeys between two Belgian stations (SNCB/NMBS): departure and arrival times, live delays, platforms, transfers, cancellations.
Use when: someone needs to travel by train in Belgium (e.g. Brussels to Liège).
Example: {"from":"Bruxelles-Central","to":"Liège-Guillemins"}
```

## Changes things (3)

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

### `be_rail_disturbances`

- 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
Current works and disruptions announced on the SNCB/NMBS network.
Use when: before advising a train trip in Belgium, to warn about strikes, works or incidents.
Example: {}
```

### `be_station_departures`

- 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
Next train departures from one Belgian station: time, destination, platform, live delay, cancellations.
Use when: someone is at (or going to) a station and wants the next trains.
Example: {"station":"Namur"}
```

### `be_train_details`

- 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
All stops of one Belgian train today with live delays and platforms.
Use when: you know the train number (e.g. IC 2117, S1 1956) and want where it is or when it reaches a stop.
Example: {"train":"IC 2117"}
```

## Only reads (1)

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

### `be_find_station`

- The name "be_find_station" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Finds the exact Belgian station names matching a word (any language).
Use when: a station name is ambiguous or misspelled.
Example: {"query":"Bruxelles"}
```
