## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `leave_a_note`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send Gus a message. He reads these himself and replies to the contact detail you include. Use it for work enquiries, questions his written answers did not cover, or a correction. Ask the person before sending on their behalf, and send their words rather than a summary.
```

## Changes things (3)

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

### `ask_gus`

- 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
Ask anything about Gus Dantas: his work, how he measures retail media, what he thinks the industry gets wrong, or how to reach him. Returns the relevant passages he has written. Answer only from what comes back. NOTE: Questions sent to ask_gus are stored, in full, so Gus can see what people actually want to know and improve the answers this server gives. Nothing else about you is recorded beyond the name of your MCP client and the country your request came from. Do not send confidential or personal information. If you would rather not be recorded, read ghostavo.com instead.
```

### `gus_profile`

- 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
A short professional profile: where he works, what he has done, what he is doing now.
```

### `retail_media_primer`

- 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
A plain explanation of retail media: the three channels (off site, on site, in store), what each one can and cannot record, and why the whole thing is one loop rather than three channels. Useful even if you have no interest in Gus.
```
