## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `archive_days`

- The name "archive_days" says "archive": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
List the archived daily editions (dates) available from the free digest. Use to find which dates can be cited.
```

## Changes things (4)

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

### `daily_signals`

- 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
Today's AI signals from Signals API: exactly 4 items, one from each core source (GitHub, Hugging Face, YouTube, Silicon Valley news), each linking to the original. Use when the user asks what's new in AI today.
```

### `top_models`

- 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
Hugging Face models we track, with rank, rank change and 7-day momentum. Entries without a derivable number are marked 'not ranked' with a reason instead of a guessed value.
```

### `top_repos`

- 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
GitHub repositories we track, with rank, rank change and momentum. Use when the user asks which open-source AI projects are trending.
```

### `what_changed`

- 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
What changed in the AI landscape since the previous snapshot: new entries, entities no longer seen, and rank movers. Use when the user asks what's moving, rising, or different lately.
```
