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

With no annotations, the description carries the full burden; it does disclose a genuinely important behavioral trait that structured fields do not: a paid x402 call costing $0.22 in USDC on Base, which tells the agent an auth/payment flow is required. It says nothing about latency, failure modes, or what a risk result looks like, so the disclosure is partial.

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?

Two compact fragments, front-loaded with what the tool returns before pricing. Slight deduction because the pricing clause is compressed to the point of garble ('Agent-grade DD Price:'), reading more like a sales tag than usable guidance.

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?

The input side is simple and fully covered by the schema, and the cost/auth requirement is stated. But for a paid, two-parameter analysis tool with no output schema, the description never indicates what comes back — a risk score, a report, a verdict — which an agent needs to decide whether to pay for the call.

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 coverage is 100% — chain enumerates ethereum|base|arbitrum and contract is typed as a 0x address string — so the schema already does the work. The description adds no parameter-level meaning, which is the expected baseline.

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?

Names the resource precisely (deep DeFi risk) and enumerates the included dimensions: basic metrics plus exploit history, TVL, and full tokenomics. The prefix 'basic +' implicitly signals it is a superset of defi-risk-basic, but that sibling is never named, so differentiation is left for the agent to infer.

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 phrase 'Agent-grade DD' implies due-diligence use, which hints at when to reach for this rather than the cheaper basic variant, but there is no explicit when-to-use/when-not statement and no mention of the obvious alternative defi-risk-basic. Guidance is implied only.

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