## Findings

- **warn** Annotations that disagree with the tool in `convert_probability` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "convert_probability" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "convert_probability" says "convert": a word for a change.
```


## Changes things (5)

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

### `calculate_ev`

- 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
Use for "is this contract mispriced" and "what is my edge". Give a Kalshi or Polymarket price in cents and your own probability; returns the % expected-value edge and a BUY / SELL / SKIP read.
```

### `convert_probability`

- The name "convert_probability" says "convert": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Convert between implied probability, American odds, and decimal odds. Give one value and its format and get all three back (American odds carry no commas, e.g. +441 or -200). Use for "what is +150 as a probability", "convert 62% to American odds", "decimal to implied odds".
```

### `kelly_size`

- 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
Compute the optimal Kelly position size for a prediction-market contract. Given your win probability, the market price (which sets the payout), your bankroll, and a Kelly fraction (full / half / quarter / eighth), returns the dollar stake and a risk rating. Use for "how much should I stake", "what is my position size", "Kelly sizing for this trade".
```

### `nhl_edge`

- 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
Use for "NHL predictions tonight" and "Stanley Cup odds". Tonight's NHL games on Kalshi — moneyline, puck line, totals, period markets — as Market · Model · Fair, starting goalies checked first. market=goals: anytime and first-goal contracts; market=futures: Cup, conference and division markets on Kalshi and Polymarket (international book) vs a 10,000-season sim. Free.
```

### `track_record`

- 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
Use for "how accurate is your model" and "what's your track record". Every graded PredictionMarketsPicks signal per engine (bitcoin, gold, silver, oil, weather, NHL) and the daily editorial call (POTD): W-L, net P/L, a 95% win-rate range and the current model era, and the NFL model's backtest. WATCH calls are reported apart.
```

## Only reads (1)

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

### `find_arbitrage`

- The name "find_arbitrage" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use for "where is the arbitrage" and "Kalshi vs Polymarket price gaps". Cross-venue gaps on the same sports contract (NFL, NBA, NHL, MLB) against Polymarket's international book: the gap in pp, the WATCH/ARB signal, the cheaper venue and whether both contracts settle the same way (settlement_match). Free: the top 3 gaps in full; Pro returns the whole board.
```
