Robinhood Chain trending tokens

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses the cost (up to $0.008 USDC.e per call) and payment mechanism, which is crucial operational context. However, it does not disclose potential rate limits, response format, or pagination 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 two sentences: the first defines the tool's purpose and key filtering rule, the second states the cost. Every word earns its place, and it is front-loaded with the most critical 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?

For a simple list tool with 2 fully documented parameters and no output schema, the description is mostly complete. It covers the resource, metric, default exclusion behavior, and cost. It could be improved by stating the sort order (e.g., descending) or what fields the returned objects contain, but it is sufficient for basic usage.

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 baseline is 3. The description adds meaningful nuance by explaining that Stock Tokens are excluded unless includeStock=true, which goes beyond the schema's 'true to include tokenized Stock Tokens'. The 'limit' parameter is not given additional context, but the coverage is complete.

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 identifies the tool's function: returning trending tokens on Robinhood Chain sorted by 24h volume. It also specifies the scope (Stock Tokens excluded by default), which differentiates it from sibling rhchain tools like rhchain_token_screener or rhchain_token_detail.

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 implies usage for finding high-volume trending tokens, but does not explicitly state when to prefer this over alternatives or provide exclusions beyond the Stock Token caveat. There is no reference to sibling tools or alternative scenarios, so the guidance is limited.

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