## Findings

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

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


## Deletes or cancels (5)

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

### `ask_coach`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Sends a message to their MONS coach, in the same thread as the app, and returns the coach's reply. Use for any training question: soreness, a missed session, how a session should feel. The coach may adjust their workouts.
```

### `edit_schedule`

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

Description, as the server wrote it:

```

### `morning_check_in`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Each day is planned on its own each morning. When the athlete's day is different, this tells the coach how many minutes they have today and what they cannot do, and the coach plans today's sessions again around it. Returns them. Takes up to a minute.
```

### `remove_challenge`

- The name "remove_challenge" says "remove": a word for removing or ending something.

```

### `about_mons`

- Nothing in its name or description says what it does, so it is counted as a write.

```

### `add_challenge`

- The name "add_challenge" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text

```

### `check_readiness`

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Picks the challenge to aim for from the person's training, how many weeks they are from it, and the one thing that sets the date. Returns the next question while one is unanswered, then the challenge and verdict. Send every answer so far each time.
```

### `ladder`

- 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.

```

### `my_profile`

### `sign_up`

- The description's first verb is "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Sets up the signed-in person's MONS account, as the app's onboarding would. Pass the challenge and answers from check_readiness when there are some. Does nothing to an account already set up.
