## Findings

- **warn** Base64 strings in `gaip_check_sar_receipt` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at examples[0].public_key contains a 43-character base64 string.

```


## Deletes or cancels (1)

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

### `gaip_watch_remove`

- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Use this when asked to stop watching an agent or service. Pass your `continuity_handle` and the `watch_id`. Its stored events are deleted; retained receipts stay verifiable. Free, no account; records a GAIP receipt only. Inputs must be public and non-personal.
```

## Changes things (20)

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

### `assurance_complete`
