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

No annotations are provided, so the description carries full burden for behavioral disclosure. It does not mention whether the operation is read-only, whether it has side effects, rate limits, or any other behavioral constraints. The description only states the content, not the behavior.

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 extremely concise—a single sentence with no unnecessary words. It is front-loaded with the key subject. However, it could arguably be too terse, missing an explicit verb that would improve clarity without adding length.

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?

With no output schema, the description should explain what is returned (e.g., format, fields). It only says 'Tradeable asset universe', which is too vague. The agent does not know whether it receives asset symbols, full metadata, or a list of objects. Completeness is low given the lack of structured return information.

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?

There are zero parameters, and the schema coverage is 100% (trivially). The description adds no parameter-level detail, but with no parameters, a baseline of 4 is appropriate. The description is clear about what the tool returns, which is sufficient for a parameterless tool.

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 states that the tool provides the tradeable asset universe for Hyperliquid DEX. It uses a noun that implies a list, which distinguishes it from siblings like 'candles' or 'history'. However, it lacks a specific verb (e.g., 'lists') and does not explicitly differentiate from tools like 'search' or 'context'.

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?

No guidance is provided on when to use this tool versus alternatives. The description only states what it is, without mentioning prerequisites, typical use cases, or situations where another tool would be preferred. Sibling tools exist (e.g., 'candles', 'history') but no differentiation is offered.

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