## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `calculate_australian_business_date`

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

Description, as the server wrote it:

```untrusted-server-text
Add or subtract Australian business days from a date for a specified state or territory. Positive numbers move forward and negative numbers move backward. The start date is excluded.
```

### `calculate_australian_deadline`

- 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
Calculate an Australian deadline using either calendar days or business days, with an explicit start-date counting rule and optional rolling to the next or previous business day when the calculated date is not a business day.
```

### `check_australian_business_day`

- 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
Check whether a date is a business day in an Australian state or territory and return the previous and next business day.
```

## Only reads (1)

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

### `count_australian_business_days`

- The name "count_australian_business_days" says "count": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Count business days between two Australian calendar dates for a specified state or territory. Boundary inclusion is explicit so agents do not have to guess the counting rule.
```
