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

With no annotations supplied, the description has to carry the full behavioral burden. It does add genuinely useful context: the underlying data source (Jupiter token list) and a payment/quota model (free trial calls per signed wallet). It omits what a result looks like, how matching works, or what happens on empty results.

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?

A single compact line, front-loaded with the tool identifier, purpose, and data source. No filler, though the emoji and pricing clause occupy space that could have been spent on parameter semantics.

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, no annotations, and four fully undocumented parameters. For a multi-field search tool, the definition leaves the agent guessing how to construct a query, which is a material 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?

Schema description coverage is 0% and the description says nothing about the four parameters. This is especially harmful because q, name, query, and symbol are overlapping search inputs whose precedence and interaction (AND vs OR, required vs optional) are completely undocumented anywhere.

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 gives a verb and resource ('Solana token search') and names the data source (Jupiter token list), which is concrete. However, it does not distinguish this from sibling tools such as x402-token-search, x402-find, or x402-search, so an agent cannot tell from the text alone which search tool is appropriate.

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 on when to use this versus alternatives, no prerequisites, and no exclusions. The only contextual note is a pricing/trial clause ('5 free trial calls per signed wallet'), which is about cost, not usage selection.

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