## Findings

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

```untrusted-server-text
The server marks "ssl_check" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The description's first verb is "open": a word for a change.
```


## Changes things (1)

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

### `ssl_check`

- The description's first verb is "open": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Opens its own TLS handshakes to one public host with openssl, using the URL's explicit port or 443 by default, and reports what they establish: which of TLS 1.3, TLS 1.2, TLS 1.1, TLS 1.0 and SSLv3 the server accepts, a protocol-support grade, and the certificate the server actually serves (subject, issuer, covered hostnames, hostname match, and validity dates). Reach for it on padlock, HTTPS, 'Not Secure', certificate-expiry and wrong-hostname questions, and to inspect which certificate is served after a renewal on the probed endpoint; this does not verify every load-balanced node. It does not fetch the page or establish whether plain HTTP is actually served or redirected, and it is not a browser trust decision: no chain-of-trust build, no revocation check, no cipher-suite inspection. Measured 0.05-1.5 seconds against real hosts; each probe is cut off at 12 seconds.
```
