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

With no annotations, the description carries the full burden and does well on the expensive parts: it discloses cost ($0.01 per call in USDC on eip155:8453), the x402 payment payload location in params._meta, and the HTTP endpoint. It omits what happens if payment is missing (error vs 402 challenge) and what the response contains.

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?

Three short sentences, front-loaded with purpose, then price, then transport detail. Every clause carries information, though the raw URL could arguably live in the schema rather than prose.

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?

No output schema and no annotations mean the description must explain both behavior and results. Payment and pricing are covered well, but the return payload (what risk/liquidity/price fields come back) and payment failure behavior are left undocumented for a paid aggregate tool.

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?

Only one parameter with 0% schema coverage, and the description adds just enough to say it is a 'Base token' without specifying whether that is a contract address, symbol, or pair. The schema also marks the parameter as not required, and the description never clarifies what happens when it is omitted.

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?

States a specific resource and scope: a combined due-diligence bundle for a Base token covering risk, liquidity and price. That distinguishes it implicitly from the single-focus siblings (basedue__tokenrisk, basedue__price, basedue__due) because it advertises the aggregation. It stops short of naming those siblings explicitly.

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 'in one call' implies you should use this when you want all three data categories at once, but there is no explicit when-to-use, when-not, or named alternative such as basedue__due or basedue__report. The agent must infer the routing rule from the field list.

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