## Findings

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

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

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


## Changes things (1)

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

### `nexez_validate_negotiation`

- The name "nexez_validate_negotiation" says "validate": a word for reading.
- The description's first verb is "evaluate": 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
Evaluate proposed terms against an exact offer and the seller's published rules in a forced dry run. Returns rules-evaluation JSON text or validation errors. Inspect the offer first and supply its required terms. Never submits a proposal, contacts a seller, or writes a negotiation.
```

## Only reads (4)

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

### `nexez_directory`

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

Description, as the server wrote it:

```untrusted-server-text
Browse published Nexez listings without requiring a buyer query. All filters are optional. Returns directory JSON text with listing summaries and readiness information. Use nexez_search when you need ranked matches for a specific buyer request.
```

### `nexez_get_page`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch one listing's structured agent manifest as JSON text, including seller profile, offers, configuration requirements, and published actions. Use a slug returned by search or directory; inspect exact offer identifiers and requirements before validation.
```

### `nexez_search`

- The name "nexez_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find services or products for a specific buyer request. Returns JSON text with ranked results, structured offers, listing slugs, agent.json URLs, and applied filters. Use nexez_directory for broad browsing, then nexez_get_page to inspect an exact offer before a dry run.
```

### `nexez_validate_checkout`

- The name "nexez_validate_checkout" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Dry-run checkout for an exact published offer. Returns validation JSON text with offer readiness or errors and missing requirements. Inspect the offer with nexez_get_page first. Never charges or creates an order; a successful check is not a completed purchase.
```
