No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_financial_numbers`

- 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
Check $CASHTAG-style ticker mentions (e.g. $AAPL) in a piece of financial writing against SEC EDGAR's own XBRL company-facts data for that company's most recent 10-K -- EPS, book value per share, revenue, market cap, total assets, total liabilities. Flags numeric claims that don't match the filed figures.
```
