## Findings

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

```untrusted-server-text
The server marks "request_ride_link" 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 name "request_ride_link" says "request": a word for a change.
```

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

```untrusted-server-text
The server marks "post_ride_link" 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 name "post_ride_link" says "post": a word for a change.
```


## Can't be undone (2)

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

### `post_ride_link`

- The name "post_ride_link" says "post": a word for a change.
- 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
For a driver: a link where the person posts a drive they are already taking on Seat Sherpa, the carpool marketplace. Drivers set their own seat price, riders share costs like gas and tolls, and riders searching that route get notified. Use it when the person is the one driving (for example "I'm driving to LA on Friday, can I take people?"), not to find a ride. Takes the starting place, the destination and an optional date. The driver signs in and posts on the page; this tool only builds the link and posts nothing.
```

### `request_ride_link`

- The name "request_ride_link" says "request": a word for a change.
- 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
For a rider when no ride fits: a link where the person posts a ride request on Seat Sherpa, the carpool marketplace, so drivers on that route see it and get notified, and the person hears back when a matching ride is posted. Use it after search_rides finds nothing that works (that answer already includes this link), or when the person asks to be told about a trip nobody has posted. Takes the same places and optional date as search_rides. The person signs in and posts the request on the page; this tool only builds the link, posts nothing, and never needs names, phone numbers or emails.
```

## Only reads (3)

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

### `get_ride`

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

Description, as the server wrote it:

```untrusted-server-text
Public details of one Seat Sherpa ride by its id (from search_rides or a seatsherpa.app/ride link): route and stops with estimated times, departure (Pacific), seats left, all-in price per seat in USD, the driver's first name, rating and trips, the driver's note to riders, flexibility, the cancellation policy, and the booking link. Read-only.
```

### `list_service_areas`

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

Description, as the server wrote it:

```untrusted-server-text
The California and Nevada areas Seat Sherpa carpools run between. Use it to check whether a trip is covered before searching.
```

### `search_rides`

- The name "search_rides" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find upcoming long-distance carpool rides on Seat Sherpa (California and Nevada) where everyday drivers sell the empty seats on a trip they are already taking, and riders split the cost of gas. Give a starting place and a destination as city or place names (for example "San Francisco" and "Los Angeles"), and optionally a travel date. Returns rides with open seats: route, departure date and time (Pacific), seats left, the all-in price per seat in USD (what the rider pays, fees included), the driver's first name, and a link where the person books. Rides that stop in a city count for that city, so a San Jose to San Diego ride with a Los Angeles stop is found for Los Angeles to San Diego. Booking happens on the link; this tool cannot book. Rides on a nearby route (for example a San Francisco ride for a San Jose search) are listed separately as nearby_rides; say they are nearby, not exact. When no ride fits exactly, the answer includes a link to post a ride request for that route (the same link request_ride_link gives).
```
