Tokenized stocks on Hyperliquid spot (xStocks, Dinari)

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

readOnlyHint=true already establishes this as a safe read; the description adds useful context by enumerating what each section returns (volume, holders, liquidity depth, top holders). It stops short of disclosing pagination, rate limits, or auth requirements, so with annotations carrying the safety profile this is only modest added value.

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?

Front-loads the resource and its section semantics; every sentence contributes. The long token enumeration is informative but slightly inflates the opening sentence.

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?

For a read-only, no-output-schema tool with a fully documented schema, the description covers the resource, its tokens, and all four section behaviors adequately. Missing only return-format/pagination detail, which is minor here.

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 schema documents all six parameters. The description goes beyond it by explaining what each section value means and how days applies to timeseries vs liquidity, adding genuine semantic value over the raw enum.

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 (tokenized stocks on Hyperliquid spot) with concrete token examples and the four data views it serves. An agent can distinguish it from the perp/staking/revenue siblings, though the '/spot-stocks page' framing is slightly URL-flavored rather than task-oriented.

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 section descriptions imply how each mode is used (current for summary, timeseries for daily metrics, etc.), but there is no explicit when-to-use/when-not or named alternative. Usage is left to inference from the section list.

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