## Findings

- **warn** Annotations that disagree with the tool in `get_test_address` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_test_address" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "get_test_address" says "get": a word for reading.
```


## Changes things (1)

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

### `get_test_address`

- The name "get_test_address" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Reserve a single-use address to send a draft email to, for a full check.

    Returns the address and the URL its report will appear at. The address
    accepts exactly one message and expires after an hour. The email has to be
    sent by the person, from the platform or mailbox they really send from:
    half the checks read what that platform adds. The report covers 42 checks
    (SPF, DKIM, DMARC, reverse DNS, TLS, blocklists, content, links, the
    Gmail and Yahoo bulk-sender rules) and a plan of what to fix.

    lang is decided now because the message arrives minutes later over SMTP,
    which carries no hint of who is waiting for it. What wait_for_report
    returns quotes check lines in English whatever it is set to; the person
    following report_url sees their own language.
    
```

## Only reads (3)

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

### `get_message_source`

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

Description, as the server wrote it:

```untrusted-server-text
The message exactly as it was received: headers, both bodies, source.

    Useful when a finding points at a header and the agent needs to see what it
    actually sent rather than what it believes it sent. The message is kept
    for an hour after it arrives and then deleted; within that hour anyone
    with the slug can read it. After that only the report remains.
    
```

### `get_report`

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

Description, as the server wrote it:

```untrusted-server-text
Read a report by its slug without waiting, with provider placement so far.

    The report stays at its link for good and anyone with the link can read
    it: the checks, the score, the fix plan, and the subject and sender of
    the email.
    
```

### `wait_for_report`

- The name "wait_for_report" says "wait": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Wait until the message arrives and has been analysed, then summarise it.

    Call it after the email has been sent to the address from
    get_test_address. Blocks rather than returning "not ready yet": an agent
    told to poll writes a sleep loop and usually gives up before the analysis
    finishes. Provider placement keeps filling in for up to 30 minutes after
    the report; get_report reads the latest.
    
```
