## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The input addresses people (input.candidate.to): what it sends cannot be taken back.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The input addresses people (input.expectation.candidate.to): what it sends cannot be taken back.
```


## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `preflight_transaction`

- The input addresses people (input.candidate.to): what it sends cannot be taken back.
- 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
Before signing: simulate one unsigned Base Mainnet (8453) candidate (chain_id/from/to/value/data); inspect call success/revert, top-level destination and L2 fee constraints, Judgment, reason codes and evidence. Free; no API key, wallet or payment. Complete supported EIP-1559 fee_estimation context optionally estimates L1/L2/applicable Operator/Total Network Fee separately; legacy Judgment is unchanged, not automatic PASS. Inspect http_status, response.judgment and response.simulation. After broadcast use verify_transaction. No signing, broadcasting, custody, asset-delta/risk scan or execution guarantee.
```

### `verify_transaction`

- The input addresses people (input.expectation.candidate.to): what it sends cannot be taken back.
- 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
After independent broadcast: verify a Base Mainnet (8453) transaction against explicit inclusion, receipt-status and optional candidate-field expectations. transaction_hash is required; default checks inclusion, NOT receipt success. Free; no API key, wallet or payment. Read http_status, response.verification.state and response.observation_errors; missing evidence is not success. Before signing use preflight_transaction. VERIFIED is not finality, ownership, causality, asset-balance change verification or a swap economic-outcome guarantee. No signing, broadcasting or custody.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `dll-execution`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__dll-execution__preflight_transaction",
      "mcp__dll-execution__verify_transaction"
    ],
    "deny": []
  }
}
