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

With no annotations, the description carries the behavioral disclosure burden. It does reveal meaningful behavior: the call is paid ($0.10 x402/TCX), the endpoint is a POST, and unpaid calls return live PAYMENT-REQUIRED challenge data. However, it never states what happens after payment, what a successful response contains, or whether the operation has side effects. The provided payment behavior is useful but incomplete.

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 contains several operational details (pricing, endpoint, default body, unpaid behavior) without much waste. However, it is not front-loaded with the tool's purpose; it begins with a redundant repetition of the name and price. It earns some efficiency credit but sacrifices clarity for brevity.

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?

This is a paid external API with multiple payment-related parameters and no output schema, yet the description does not state what the tool returns or how to interpret a successful call. It explains the payment-challenge path but not the actual intel/security results. For an agent to call this confidently, it needs a clear result description and a reason to prefer it over closely named siblings.

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 is 3 even with no additional parameter explanation in the description. The description repeats the default body values (chain, limit, maxMcapUsd, meta) but adds no meaning beyond the schema. It does not clarify how limit or maxMcapUsd shape results, nor what meta:'ai' does.

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 opens with the tool name itself ('intel-trenches-screen') and then discusses price, endpoint, and default body, but never states what the tool actually does. It does not say what it screens, analyzes, or returns, and it does not distinguish 'screen' from the sibling intel_trenches tool. This is essentially a tautological label plus API mechanics.

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?

There is no guidance about when to use this tool versus alternatives such as intel_trenches, intel_meteora, or security_scan. The default body hints at Solana low-market-cap queries, but no explicit context, exclusions, or alternative-conditions are provided. The reader must infer use from the tool name and default payload.

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