Args: chain: chain id string (default 'base'). from_addr: the agent's wallet address (the transaction sender). tx: the transaction to evaluate before signing, e.g. {"to": "0x...", "data": "0x...", "value": "0x0"}. |

Scored across 1 tool
Only one tool exists, so there is no possibility of confusion. The tool's purpose is clearly defined.
The single tool name 'sentinel_guard' is descriptive and follows a clear pattern. Consistency is trivially maintained with one tool.
While only one tool, it fully covers the server's focused purpose of transaction security evaluation. The count is on the lower end but appropriate for a single-purpose service.
The tool provides a complete solution for its stated goal: evaluating transactions before signing. It includes all necessary inputs and outputs (verdict, score, receipt) with no obvious gaps.
