get_trades

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

Annotations already declare read-only, safe, idempotent behavior. Description adds value by noting data availability from April 2023 and cursor pagination, which are beyond structured fields.

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?

Three concise sentences with clear front-loading of main action. No wasted words; every sentence adds useful information.

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?

Given rich annotations and output schema, description covers purpose, return fields, data availability, and pagination. Lacks mention of ordering or rate limits but is sufficient for typical use.

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?

Input schema fully describes all 5 parameters (100% coverage). Description references time range and pagination but adds no new semantics beyond the schema.

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?

Clearly states it retrieves Hyperliquid trade/fill history for a coin over a time range, listing return fields. However, it does not differentiate from many similar trade tools (e.g., get_hip3_trades, get_lighter_trades) which share the same purpose.

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?

Provides no guidance on when to use this tool versus alternatives. It describes basic functionality but omits context like preferred use cases or prerequisites.

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