## Findings

No check matched anything in these tool definitions.


## Changes things (6)

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

### `aggro_board`

- 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
Aggrometer's signature metric: aggro = live Twitch viewers / concurrent Steam players, same hour, per game (min 500 players). Above 1.0 means more people watch than play — spectacle games, watch-to-learn genres. A sudden aggro jump is an early attention signal.
```

### `game_detail`

- 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
Full profile of one game by Steam app id: hourly player history, Twitch viewer history, daily viewer-hours, price/discount history, top-seller rank appearances, clips-per-day virality, review counts and review-activity buckets back to launch, Wikipedia pageview history (monthly since 2018 + daily), developer news velocity, achievement-completion depth, and metadata (genres, developer, publisher). Use search_games first if you only know the name.
```

### `genre_rollup`

- 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
Every Steam genre aggregated: game count, combined players, combined live viewers, genre-level aggro ratio, and combined hype (anticipation) of the genre's unreleased games. The whitespace signal: high players + low hype = an underserved genre; low players + high hype = a wave arriving.
```

### `hype_board`

- 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
Aggrometer Anticipation Index: top-wishlisted unreleased Steam games scored with pre-release Twitch attention and Wikipedia attention surges (score = wishlist-rank points + log-scaled live viewers + log-scaled pageview surge vs 30-day average). A relative index - compare games against each other; week-over-week change is the launch-anticipation signal.
```

### `top_played`

- 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
Top 100 games by current Steam concurrent players (updated hourly). Optionally scoped to one Steam genre.
```

### `top_watched`

- 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
Top 100 games by current live Twitch viewership (15-min updates). Optionally scoped to one Steam genre.
```

## Only reads (2)

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

### `get_summary`

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

Description, as the server wrote it:

```untrusted-server-text
Warehouse status: how many games are tracked, hours of history recorded, snapshot counts, and data freshness timestamps. Call this first to understand data coverage.
```

### `search_games`

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

Description, as the server wrote it:

```untrusted-server-text
Find games in the tracked catalog by name (substring match). Returns app ids for use with game_detail, plus current player counts.
```
