## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `verify_evidence_pack`

- 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
Verify a review pack receipt by receipt. Each verdict comes from the signed envelope itself, never from stored state, and results are per-receipt, never an average.
```

### `verify_receipt`

- 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 that a record still says what was signed: the permitted or refused decision, unchanged, under Seal's published issuer keys or a key you supply. Handles both formats: ATTESTATION-v1 (a model-call decision) and ACTION-v1 (an agent tool action). No Aqta service in the check.
```

### `workspace_summary`

- 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
Outcome, model and policy counts across your recent receipts. Requires your aqta_ key.
```

## Only reads (7)

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

### `decode_receipt`

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

Description, as the server wrote it:

```untrusted-server-text
Read a receipt field by field, with stated limits. Does not check the signature.
```

### `explain_attestation_format`

- The name "explain_attestation_format" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The receipt format: fields, outcomes, verification commands, and what a signature does not establish. Use before describing the format.
```

### `get_public_key`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the published Seal signing key.
```

### `get_review_pack`

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

Description, as the server wrote it:

```untrusted-server-text
The published sample evidence pack: fixed review question, bound receipts, disclosure.
```

### `get_sample_receipt`

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

Description, as the server wrote it:

```untrusted-server-text
A genuine signed receipt from the sample workspace (demo key), for trying verification.
```

### `get_transparency_proof`

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

Description, as the server wrote it:

```untrusted-server-text
Inclusion proof plus signed tree head for one of your receipts. Requires your aqta_ key.
```

### `list_my_receipts`

- The name "list_my_receipts" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List your workspace receipts filtered by outcome, policy, model, or date range. Requires your aqta_ key as Bearer.
```
