## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `festival_details`

- 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
Look up one festival by name in a given year and return its computed date, lunar month, tithi and the rule behind it. Name matching is case-insensitive and partial (e.g. 'diwali', 'holi', 'makara'); first match wins. Use when the user asks when a specific festival is. Do NOT use to list several; use list_festivals.
```

## Only reads (3)

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

### `festivals_in_month`

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

Description, as the server wrote it:

```untrusted-server-text
List the Hindu festivals and sankrantis that fall in one calendar month of a year (2020-2040), sorted by date; may be empty. Use for questions like 'festivals in October 2026'. Do NOT use for the whole year (use list_festivals) or the next one (use next_festival).
```

### `list_festivals`

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

Description, as the server wrote it:

```untrusted-server-text
Compute all major Hindu festivals (Ugadi, Holi, Diwali, Navratri, Ganesh Chaturthi, etc.) and the 12 solar sankrantis for one year, 2020-2040, sorted by date. Dates are approximate (+/-1 day). Use for a full-year overview. Do NOT use for one month (use festivals_in_month) or the next upcoming one (use next_festival).
```

### `next_festival`

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

Description, as the server wrote it:

```untrusted-server-text
Find the first Hindu festival or sankranti falling on or after a given date (looks into the following year if needed; 2020-2040 only). Use for 'what is the next festival?' questions. Do NOT use for a list; use list_festivals or festivals_in_month.
```
