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

With no annotations, the description adds significant behavioral context: it discloses the $0.25 cost via x402, the data sources (GoPlus holder list, all DEX pairs), and that it uses same free upstreams as cheaper SKUs. This goes beyond what annotations would typically provide.

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?

Every sentence in the description adds value: pricing, purpose, specifics of included checks, and contrast with cheaper versions. It is front-loaded with key information and avoids redundancy.

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 description lists what the report contains (rug-check, whale-concentration, etc.), which gives a good idea of the output, but it does not specify the response format, schema, or error handling. Given no output schema, this is a moderate gap.

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?

The description does not add any meaning beyond the input schema. Two of three parameters (chain, address) are already documented in the schema, but the x_payment parameter is left undescribed in both schema and description, and the description offers no parameter-level guidance.

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 identifies the tool as a comprehensive pre-trade report including rug-check, whale-concentration, liquidity depth, and socials/website links. It distinguishes itself from cheaper SKUs by being a depth/convenience bundle, making its purpose unambiguous.

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 implies that this tool is for a full pre-trade check when you need depth and convenience, but it does not explicitly state when to use it versus sibling tools like token_security_check or dex_token_data, nor does it provide when-not-to-use guidance.

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