## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `about_the_aggregate`

- 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
What this data is: how the IRT fusion works, current coverage counts, update cadence, and how to cite it.
```

## Only reads (7)

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

### `compare_models`

- The name "compare_models" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Head-to-head between 2-4 models: aggregate ranks, rating gap with a significance note based on the standard errors, and notable benchmarks they share.
```

### `get_benchmark`

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

Description, as the server wrote it:

```untrusted-server-text
One benchmark in depth: what it measures, the original source leaderboard URL, IRT stats (difficulty, noise, model coverage), skill weights, and the current top models on it.
```

### `get_leaderboard`

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

Description, as the server wrote it:

```untrusted-server-text
Top of the cross-benchmark aggregate ranking: every model placed on one rating scale by an IRT model fit over public benchmark leaderboards (call about_the_aggregate for the current coverage counts). One row per model by default, fused across reasoning-effort settings. Supports paging via limit/offset.
```

### `get_model`

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

Description, as the server wrote it:

```untrusted-server-text
One model in depth: aggregate rank, Aggregate Rating with standard error, provider, what it is, cost per task where known, and its most notable benchmark results (with percentiles).
```

### `get_prediction_duel`

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

Description, as the server wrote it:

```untrusted-server-text
Guesswork — the public prediction duel: every day frontier LLMs and The Aggregate's own IRT model predict newly scraped benchmark scores before seeing them, and the errors are scored. Returns the current monthly standings, wins and losses included.
```

### `search_benchmarks`

- The name "search_benchmarks" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find benchmarks in the aggregate by (partial) name. Returns model coverage, difficulty on the rating scale, and the benchmark page URL.
```

### `search_models`

- The name "search_models" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find ranked models by (partial) name or provider. Returns rank, Aggregate Rating and the model page URL. One row per model by default, fused across reasoning-effort settings.
```
