## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `business_days`

- 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
Do business-day math that skips weekends and your holiday list. FREE.

Either add N business days to start_date (set add_days), or count the
business days between start_date and end_date (set end_date). Typical
input {"start_date": "2026-03-02", "add_days": 10} returns
{"result_date": "2026-03-16", "result_weekday": "Monday", ...}; with
end_date set it returns {"business_days_between": N, "from": ..., "to": ...}.

Use when the span must exclude weekends and named holidays. Not for plain
calendar-day differences, which are a direct subtraction, and not for
scheduling backward from a fixed deadline (deadline_planner). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "dates must be YYYY-MM-DD"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

### `deadline_planner`

- 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
Plan a task schedule backward from a hard deadline in business days. PREMIUM (license).

Given ordered tasks with business-day durations, returns each task's
start/end dates, the latest safe start, and slack from today. Typical
input {"due_date": "2026-06-01", "tasks": [{"name": "Draft", "days": 3},
{"name": "Review", "days": 2}]} returns {"schedule": [...],
"latest_safe_start": "YYYY-MM-DD", "slack_business_days_from_today": N,
"verdict": "..."}.

Use when the end date is fixed and steps must be placed backward from it.
Not for forward counting from a start date (business_days) and not for
response-time targets (sla_due). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "due_date must be YYYY-MM-DD"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

### `recurrence_expand`

- 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
Expand a recurrence rule into a concrete list of ISO dates. FREE.

Set every_days for a fixed interval, or weekly_on for specific weekdays.
Typical input {"start_date": "2026-01-05", "every_days": 14, "count": 3}
returns {"dates": ["2026-01-05", "2026-01-19", "2026-02-02"]}.

Use when a recurrence rule has to become concrete dates. Not for counting
working days in a span (business_days) and not for finding a slot across
zones (meeting_overlap). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "start_date must be YYYY-MM-DD"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

### `sla_due`

- 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
Compute when a ticket's SLA falls due, wall-clock or business-hours. PREMIUM (license).

Typical input {"opened_at": "2026-03-02T15:30", "sla_hours": 8,
"business_hours_only": true} returns {"due": "2026-03-03T15:30", "mode":
"business hours 09:00-17:00"}; with business_hours_only false the mode is
"wall-clock".

Use when a response or resolution clock has started and one due moment is
needed. Not for multi-step project schedules (deadline_planner). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "opened_at must be ISO YYYY-MM-DDTHH:MM"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

## Only reads (1)

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

### `meeting_overlap`

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

Description, as the server wrote it:

```untrusted-server-text
Find the shared meeting window across time zones inside working hours. FREE.

Give one UTC offset per participant and an optional working-hours window.
Typical input {"offsets_utc": [-8, 1, 5.5]} returns {"overlap_utc":
["HH:MM", "HH:MM"], "overlap_minutes": N, "local_windows": [...]}; when no
shared window exists it returns {"overlap": null, "verdict": "..."}.

Use when people in different zones need one shared slot. Not for
converting a single known time between zones, and not for expanding a
recurring series (recurrence_expand). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "times must be HH:MM"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```
