## Findings

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

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

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


## Deletes or cancels (1)

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

### `trip_idea_create`

- The name "trip_idea_create" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Submit the customer's trip to AirTreks — a human travel consultant takes over from there. Automatically runs plan_route to attach the full routing analysis and carrier recommendations to the trip request, so the consultant starts informed, not cold. Use this when the customer is ready to get a real quote. Requires the customer's name, email, at least 2 cities (3-letter IATA codes), a departure date for every leg, and answers to AirTreks' planning questions — call once without questionsAnswers to receive the current questions to ask.
```

## Can't be undone (1)

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

### `hub_check`

- 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
Check the best connection between two airports. Identifies dead legs (routes that fail on alliance fares), suggests hub routing fixes, and shows proven carrier combinations. Essential for transpacific, kangaroo, and intra-Asia routing.
```

## Changes things (4)

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

### `custom_route_build`

- 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
Break a complex multi-city itinerary into individually-ticketable segments with carrier recommendations. Handles routes that don't fit alliance fare rules — mixed carriers, LCCs, Gulf bridge connections, surface sectors. This is how AirTreks consultants build 90% of itineraries. Use this for any route with 4+ stops, backtracking, or region combinations that alliance fares can't cover.
```

### `fare_product_match`

- 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
Recommend the best fare product type for a route — RTW, Circle Pacific, Circle Atlantic, Open Jaw, or Custom Multi-City. Considers stop count, direction, and backtracking to match the right alliance fare structure.
```

### `itinerary_quote`

- 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
Price a complete multi-stop or round-the-world trip and get back several ways of ticketing it — cheapest, fastest, fewest stops — with the actual tickets each one is built from. Use this for trips that will not go on a single fare, which is most itineraries with 3+ stops; use fare_quote when you want one specific itinerary on one ticket. It takes about a minute, so it returns a quoteReference immediately; call itinerary_quote_status with it straight away, and that call waits for the result. Keep that reference — it is the only way to retrieve the quote.
```

### `plan_route`

- 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
The primary entry point for any multi-city trip. Give it your cities — it automatically evaluates Star Alliance RTW, oneworld RTW, AND custom mixed-carrier builds, then recommends the best approach. Handles direction detection, backtracking analysis, alliance feasibility, surface sectors, and carrier selection. The customer doesn't need to know if their trip is alliance or custom — this tool figures it out.
```

## Only reads (5)

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

### `fare_quote`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get live, bookable-quality fares for one specific itinerary — actual flights, actual prices, for the dates given. Needs a departure date for every flown leg. Use this once the customer has settled on cities and dates and wants real numbers rather than a ballpark; use route_estimate instead when dates are still open. It prices the itinerary as a single fare, so very long or awkward multi-continent trips may come back unpriceable — those genuinely need to be split across separate tickets, which is what AirTreks consultants do by hand.
```

### `itinerary_quote_status`

- The name "itinerary_quote_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch the result of an itinerary_quote using the quoteReference it returned. Call it straight away: it waits up to about 40 seconds for a quote that is still pricing, then returns the finished options, or status 'pending' if the quote needs one more call. Costs nothing and does no searching, so call it again rather than starting a second quote.
```

### `route_estimate`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a price range for a multi-city or round-the-world trip, drawn from what AirTreks customers have actually paid on those routes. Give it the cities and it returns a per-person range in USD with how much history sits behind it. Use it when someone asks what a trip will cost and you don't have exact dates yet — it needs no dates and no passenger details. It is a range from past bookings, not a live quote, so it will not reflect today's availability or seasonality; it tells you the right ballpark before anyone commits to dates.
```

### `route_suggest`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get suggested multi-stop flight routings based on regions, direction, and alliance preference. Returns up to 3 proven routing templates with bookability ratings. Great for trip planning inspiration.
```

### `route_validate`

- The name "route_validate" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate a multi-city flight routing for feasibility. Checks alliance carrier rules, identifies dead legs, warns about poison carriers, and estimates bookability. Use this before building an itinerary to catch routing problems early.
```
