## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "verify_page_links" says "link": a word for a change.
```

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

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

## Changes things (2)

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

### `generate_outreach_email`

- The name "generate_outreach_email" says "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "generate_outreach_email" says "generate" and "email": it writes something other people read. The input takes a URL (input.context.targetUrl): a request to a URL can carry data to whoever runs it.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Draft a short, personalized cold outreach email from a contact + context object using your own LLM key (BYOK). Returns a subject line and body. The API key is request-scoped and is never persisted or logged.
```

### `verify_page_links`

- The name "verify_page_links" says "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

```

Description, as the server wrote it:

```untrusted-server-text
Approximate the pages linking to a competitor using free DuckDuckGo signals (domain mentions and brand mentions). De-duplicates by host and excludes the competitor's own domain. Not a complete backlink index — a free, directional starting point for prospecting.
```
