No check matched anything in these tool definitions.


## Changes things (3)

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

### `bazi_chart`

- 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 a BaZi / Four Pillars of Destiny chart from a birth date, optional birth time and the birthplace time zone. Uses solar-term boundaries (the year changes at the Start of Spring, Li Chun) via an astronomical calendar engine. Returns the four pillars with Ten Gods, the Day Master, five-element balance, luck pillars and the coming years.
```

### `cast_i_ching`

- 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
Cast an I Ching reading with the traditional three-coin method (six tosses, bottom line first). Returns the primary hexagram, any changing lines and the relating (transformed) hexagram, with links to each hexagram's meaning. Use this instead of making up a hexagram.
```

### `draw_tarot_cards`

- 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
Draw tarot cards at random from a full 78-card Rider–Waite–Smith deck (cryptographically random, no repeats). Returns each card with its position, upright/reversed orientation, keywords and a link to its full meaning. Use this instead of inventing cards when a user asks for a tarot reading.
```

## Only reads (3)

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

### `chinese_zodiac`

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

Description, as the server wrote it:

```untrusted-server-text
Find a person's Chinese zodiac animal from a birth year or date (handles the Lunar New Year and Start of Spring boundaries for January–February births) and return the 2027 Year of the Fire Goat forecast for that sign: love, career, money and a tip.
```

### `get_hexagram`

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

Description, as the server wrote it:

```untrusted-server-text
Look up one of the 64 I Ching hexagrams by number (1–64), English name ("The Wanderer"), Chinese character (旅), Japanese name (火山旅) or pinyin (ambiguous pinyin like "lu" returns the candidates). Returns its essence, judgment, image, love and career readings, guidance and the six line texts.
```

### `get_tarot_card_meaning`

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

Description, as the server wrote it:

```untrusted-server-text
Look up the meaning of a tarot card: keywords, upright and reversed meaning, love, feelings, career and money readings, and whether it leans yes or no. Accepts names like "The Tower", "3 of Cups", "Queen of Swords" or "ace of coins".
```
