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

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered. The description adds valuable behavioral context: ranking methodology, source (DeFiLlama), noise filtering, and the $0.03 USDC x402 Base pricing/payment detail.

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 dense sentences deliver purpose, ranking logic, source, target audience, and cost with no filler. The most important scoping information is front-loaded before the details.

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?

Given the single optional parameter, existing output schema, and rich annotations, the description covers the essential operational context well. The only real gap is that the 'input' parameter remains ambiguous, but this is a minor issue for an otherwise low-complexity 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?

Schema coverage is 100%, so the baseline is 3; the single 'input' parameter is documented in the schema but only vaguely as 'parametros del producto (JSON o texto)'. The tool description does not clarify what inputs the parameter should contain or how to format them, so it adds no extra parameter-level meaning.

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 names a specific resource (young DeFi protocols with accelerating TVL) and a clear action (early detection before they get big). It also adds target users and ranking criteria, making it easy to distinguish from generic protocol-list tools.

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 clearly conveys when this tool is useful: for MEV searchers and alpha bots seeking early-stage on-chain momentum, with mega-protocol noise filtered. It does not explicitly name alternatives or exclusion conditions, but the context is strong enough to guide selection.

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