## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `basis_answer`

- 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
Ask the Basis Agent a question about attested risk state.

    Answers cite attestation hashes; ungroundable queries are refused. Never
    recommends positions or forecasts. Pass your hub API key (x-api-key header
    or ?apikey=) to attribute reads. Multi-turn: pass the envelope's
    session_id back as session_id.

    Parameters:
        query: The question (max 4000 chars).
        session_id: Session UUID from a previous envelope (optional).
    
```

### `basis_data`

- 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
Market, governance and risk data in one tool. Pick a kind:

    liquidity_depth (entity=coin id), yield_data (entity=protocol, optional),
    governance_activity (entity=protocol slug; window=days, 90),
    bridge_flows (entity=bridge id, optional), exchange_health (entity=exchange id, optional),
    volatility (entity=asset id), incidents (entity=entity id, optional),
    peg_monitor (summary of latest deviation + status per coin; detail=true with entity
    returns that coin's 5-minute series, window=hours, 24),
    venue_shift (entity=operator slug, optional), asset_footprint (entity=token or symbol),
    divergence (capital-flow vs quality signals; severity=notable|alert|critical, limit=20, window=hours 24),
    treasury_events (entity=wallet, optional), riskiest_wallets (limit=20),
    scoring_backlog (limit=20).

    Responses are capped near 12 KB; an unknown kind returns the list of kinds.
    
```

### `receipt_verify`

- 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 receipt or citation hash from an envelope (basis_answer, entity_read).

    Resolves it against the attestation tables and returns what it attests
    to, or that it is unknown. ``source`` optionally restricts the table.
    
```

### `score_history`

- 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
Daily SII score history for a stablecoin: a list of {date, score, grade} only.

        Parameters:
            coin: symbol, slug or contract address (resolved like entity_read)
            days: lookback window, 1-365 (default 30)
        
```

## Only reads (3)

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

### `entity_read`

- The name "entity_read" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up any entity by symbol, slug, contract/wallet address, operator or vault name.

        Returns {entity_type, id, score, grade, confidence, receipt_hash,
        links}. When nothing resolves returns {match: null, did_you_mean:
        [up to 5 candidates]} rather than an error.
        
```

### `get_methodology`

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

Description, as the server wrote it:

```untrusted-server-text
The Basis methodology. mode="summary" (default): index list, versions,
    component counts. mode="full": the complete SII formula, weights and
    component specifications (large).
```

### `get_stablecoin_scores`

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

Description, as the server wrote it:

```untrusted-server-text
Current SII scores (0-100) for scored stablecoins. Use before any decision involving stablecoins.

    Parameters:
        limit: max coins returned (default 25, max 500)
        fields: columns to return per coin (default id, symbol, name, issuer,
            score, grade, confidence, stale, computed_at); name "categories"
            for category scores
        sort_by: "score_desc" (default), "score_asc", or "symbol"

    One coin's detail: entity_read(query).
    
```
