- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Resolve website addresses for up to 20 selected Analytics properties. Search Console does not use this route. Requires the owner's account session; an organization key cannot authorize Google access.

```

### `commsharbor_email_mailbox_resume`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

### `commsharbor_email_security_check`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Check whether someone can send email as a domain: SPF, DKIM in common selectors, DMARC, MX, MTA-STS and BIMI, with a 0-100 score and the fixes, most severe first. Public DNS only. Free, no account. The same domain is served from memory for 10 minutes. A network can run 30 new checks per day. DKIM is looked up in common selectors only; `dkim_not_found` does not prove that no key exists. `incomplete: true` means a DNS answer failed and the score can be lower than the real one; `unread` names those parts, and a failed query never becomes a missing finding.
```

### `commsharbor_email_service_request`

- Tag outbound: The name "commsharbor_email_service_request" says "request" and "email": it writes something other people read.

The private service credential stays on the server. Mailbox passwords and message content are never returned.
```

### `commsharbor_organization_get`

- The name "commsharbor_organization_get" says "get": a word for reading.
- 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
Open an organization by id: name, your role and the CommsHarbor plan. This is how a workspace is opened. Name and role come from the shared account (null with an organization API key, which carries neither); the plan is the organization's global entitlement in CommsHarbor.
```

### `commsharbor_platform_context`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Read the monthly Brazil email security report: how many domains of city halls, state and federal government, banks and listed companies reject fake email (DMARC p=reject) and how they end SPF. Totals only, public DNS. Free, no account. Public DNS only, read once a month. The sample is built from Brazil's open company registry (Receita Federal, the email of each active head office) and the CVM register of listed companies. Only totals: no domain is listed. A share is `count / (com_mx - dmarc.nao_lido)`; domains without MX are left out. Only the DMARC policy classifies; SPF is counted but does not change the class. `percent` rounds each group to 100 by the largest remainder, the same rule as the page.
```

### `commsharbor_context`

- The description's first verb is "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve the active organization identity. Read this before a write when you are not certain which tenant is active. Guessing is how data lands in the wrong organization. An organization API key answers `kind: api_key` with its scopes.

Read the current email workspace, DNS progress and recent jobs. The ID must match X-Organization-Id. Membership is checked again for each snapshot and delivered event.

```

### `commsharbor_health`

- The description's first verb is "read": a word for reading.
