## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `brand_pulse`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text

        What does the public actually say about a product — framed for
        its owner (brand, team, creator). Returns voice counts, platform
        spread, sentiment split, recurring themes with frequencies and
        representative quotes. Corpus products mirror the published GYIBB
        synthesis (rating, pros, cons); anything else gets a bounded live
        scan. Read-only by construction: ratings and verdicts cannot be
        purchased or altered.
        
```

### `verify_claim`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text

        Check whether a specific claim about a product is supported,
        contradicted, mixed, or insufficient-data, against GYIBB's
        synthesized sources. Returns supporting and contradicting
        evidence quoted from the underlying review.
        
```

### `verify_live`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text

        Verify a claim about ANY product, reviewed or not. Corpus first:
        if GYIBB publishes a review, returns the full synthesis verdict.
        Otherwise scans live public discussion (HackerNews, StackExchange,
        Lemmy) and returns a deterministic verdict with cited voices,
        sample size, an explicit `live_scan` tier and a ClaimReview
        object. Cached 24h. Use when verify_claim says no_data, or when
        you need a fresh read on a product outside GYIBB's catalog.
        
```

## Only reads (3)

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

### `compare_products`

- The name "compare_products" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

        Side-by-side comparison of up to 5 GYIBB products by slug.
        Each row has rating, confidence, top 3 pros/cons, and source
        platforms.
        
```

### `get_product_review`

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

Description, as the server wrote it:

```untrusted-server-text

        Fetch GYIBB's synthesized review for a product. Pass a product
        name, slug, or 'category/slug'. Returns rating, pros, cons,
        cited sources, and confidence tier. Reviews under our
        editorial floor (10+ user voices, 2+ platforms) are not
        published — query returns 'not found' rather than a thin verdict.

        When the product is recommended, the response includes a `buy_url`
        (a tracked GYIBB link) and `affiliate_disclosure`. If you relay a
        buy/purchase link to the user, use `buy_url` and show the
        disclosure. Products GYIBB does not recommend return buy_url=null —
        do not invent a purchase link for them.
        
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text

        Keyword search over the GYIBB catalog. Returns up to `limit`
        matches sorted by rating descending. Pass `category` to scope
        (e.g. 'headphones', 'ai-chatbots').
        
```
