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

With no annotations provided, the description carries the full behavioral burden. It discloses that the operation is read-only and sourced from GMGN, but does not explain rate limits, authentication needs, data freshness, pagination, or what 'trending' means operationally.

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 a single front-loaded sentence with no wasted words. However, its extreme brevity leaves critical usage and parameter context unstated.

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 tool with two optional parameters, no parameter descriptions, no output schema, and no annotations, the description is too thin. It identifies the domain and read-only nature but omits what the result contains and how the interval and limit affect it.

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% for two parameters, limit and interval, and the description does not mention either parameter. It does not explain supported intervals, the meaning of the limit, or defaults, so it fails to compensate for the undocumented 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?

The description states a clear verb-like purpose: read-only trending tokens on Robinhood Chain from GMGN. It identifies the resource and source well, but does not differentiate itself from related siblings like agentcity_robinhood_signals or agentcity_robinhood_smart_money.

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 provides no guidance on when to use this tool versus alternatives. It only labels the operation as read-only, leaving the agent to infer that it should be chosen for trending-token discovery.

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