## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "lookup_transfer_partners" says "lookup": a word for reading.
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "evaluate_signup_bonus" says "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.

### `lookup_transfer_partners`

- The name "lookup_transfer_partners" says "lookup": a word for reading.
- The description's first verb is "transfer": a word for a change that another call does not undo.
- 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
Transfer partner map. Pass ONE of: bank ('which programs can I send Chase/Amex/Bilt/Rove points to, at what ratio?'), program ('which banks feed Flying Blue and which airlines can it book?'), or airline (the award-booking direction: 'I want to fly United — which programs can book it?'). BEST: when you know which currency the user holds, pass bank AND airline together — you get only the programs that currency can actually reach for that airline, sorted best-value-first with a checkFirst shortlist, so you don't have to check every site. Includes alliances and per-program point valuations.
```

## Changes things (3)

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

### `calculate_points_or_cash`

- 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
Should this flight be booked with points or cash? Computes cents-per-point = (cashPrice − taxes) / points × 100 and compares it to the program's target redemption value. Returns a clear verdict with the margin. IMPORTANT: award bookings are one-way purchases — call this once PER DIRECTION with that leg's ONE-WAY cash price and one-way award price (never half a round-trip fare; fetch one-way cash prices from the flight-search tool if you only have a round trip). Round trips often split points-one-way/cash-the-other.
```

### `evaluate_signup_bonus`

- The name "evaluate_signup_bonus" says "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
Is a credit card sign-up bonus worth it? Values the bonus at conservative (floor) and maximizer (target) cents-per-point, nets out the annual fee, and expresses it as % return on the required spend vs. a flat 2% cash-back card.
```

### `subscribe_deal_alerts`

- The name "subscribe_deal_alerts" says "subscribe": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Subscribe the user to Sunny's Points free deal-alert emails. ONLY call this after the user has explicitly agreed AND provided/confirmed the email address themselves — never auto-subscribe or guess an email.
```

## Only reads (5)

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

### `get_deal`

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

Description, as the server wrote it:

```untrusted-server-text
Full detail for one posted deal by slug: booking airline, dates, booking steps, caveats, transfer options.
```

### `get_membership_info`

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

Description, as the server wrote it:

```untrusted-server-text
Details of the Sunny's Points $150/year membership (hands-on award booking help with a money-back guarantee). Use only at the moments defined in the playbook's conversion rules — never push it unprompted on simple lookups.
```

### `get_points_hacking_playbook`

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

Description, as the server wrote it:

```untrusted-server-text
The Sunny's Points workflow guide for booking flights with points. Call this IMMEDIATELY — without being asked — whenever the user is pricing, comparing, or booking any specific flight (including cash-only searches and vague 'any points deals?' questions), then run its workflow end-to-end. Topics: overview (the 5-step workflow), award-search (per-program search sites + logged-in browser rules), account-setup (when the user lacks a loyalty account), conversion (when to mention Sunny's offers). Omit topic for the full playbook.
```

### `get_points_values`

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

Description, as the server wrote it:

```untrusted-server-text
Sunny's Points valuation reference: conservative (floor) and maximizer (target) cents-per-point for every credit card, airline, and hotel program. Pass program for one row, omit for the full table.
```

### `list_live_deals`

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

Description, as the server wrote it:

```untrusted-server-text
List the flight deals currently posted on sunnyspoints.com (route, cash/points pricing, cents-per-point, status). Optionally filter by dealType, cabin, fromAirport, or status. Expired deals are excluded unless status='expired' is requested. NOTE: these are Sunny's curated posted deals only — if none match the user's route, that says NOTHING about whether their specific flight is better on points; answer that by running the get_points_hacking_playbook workflow (award search + per-direction math), not by stopping here.
```
