Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the burden of explaining behavior. It discloses the returned information, the 0-100 risk score, the proceed/review verdict, and the pay-per-call cost. It does not explicitly state that the call is read-only or describe error behavior, but for a risk-check tool this is reasonably transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded: it states the triggering condition first, then lists outputs, then the purpose and cost. Every sentence provides necessary information and there is no filler or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter tool with no annotations and no output schema, this description is complete. It explains when to use it, what it returns, why it matters, and even discloses the per-call cost. An agent has enough context to select and invoke the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline applies. The single 'address' parameter is already described as 'Solana address to check before paying' in the schema. The tool description adds context about SOL/USDC and risk, but does not add new parameter-level semantics beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: a pre-payment risk check for Solana addresses. It specifies the resource (Solana address), the action (check risk before sending SOL/USDC), and the outputs (account type, balance, activity, risk score, verdict), which distinguishes it from sibling tools like solana_account.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly tells the agent when to use it: before sending SOL/USDC to any address, and to avoid paying dead, wrong, or program addresses. It does not explicitly name alternative tools or exclusions, but the triggering condition is clear enough for an agent to route correctly.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
