## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `a_share_announcements`

- 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
Use when the user asks what a Chinese company has announced, filed or said, or when you need a primary source to quote. Returns filing titles, dates and the cninfo PDF link. Prefer this over summarising from memory.
```

### `a_share_ask`

- 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
Use when the question needs judgement rather than a single number: why a margin moved, whether a policy applies, what an industry chain looks like, or a comparison across companies. Queues the question for a human-reviewed answer. Returns an id immediately; the answer appears in the inbox later.
```

### `a_share_financials`

- 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
Use when the user asks about revenue, net profit, gross margin, ROE, growth or leverage of a Chinese listed company, especially for a specific quarter. Returns cumulative figures as filed (not annualised) plus year-over-year growth.
```

### `a_share_quote`

- 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
Use when the user asks for the current price, change, valuation or market cap of a Chinese listed company (A-share), including when they name it in Chinese without a ticker. Returns live price, % change, PE, PB, market cap, turnover. Do not guess a price — if this tool fails, say the data source is unavailable.
```
