## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `kalshi_fee`

- 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
Kalshi's taker fee for an order on a Kalshi contract (selected balance precision; same single-fill estimate as https://degenhedge.com/tools/kalshi-fee-calculator/), the total cost, profit if it wins, loss if it loses and the win rate needed to break even. price_cents is in CENTS (95 = a 95-cent contract). KXBTC15M charges makers no fee.
```

## Only reads (2)

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

### `get_btc_window`

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

Description, as the server wrote it:

```untrusted-server-text
The Kalshi KXBTC15M Bitcoin up/down market trading now: ticker, open and close time, official strike (60-second CF Benchmarks BRTI average before the open, null until Kalshi posts it), Up (yes) and Down (no) asks and bids in cents, Kalshi's live fee schedule for the series and a Coinbase spot reference. Kalshi public data only; no prediction or signal. Refreshed about every 5 seconds.
```

### `get_graded_record`

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

Description, as the server wrote it:

```untrusted-server-text
DegenHedge's public, graded record of its Kalshi BTC 15-minute alerts: every alert sent to subscribers with a 1-99 cent entry, graded against Kalshi's official result, losses included. Overall and by entry-price bucket: signals, wins, win rate with a Wilson 95% interval, average entry, breakeven before and after a one-contract fee, data-through date. The record sits below breakeven: report the win rate only together with its average entry price.
```
