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

No annotations are provided, so the description carries the full disclosure burden. It usefully flags 'Read-only' and 'recent', but says nothing about recency window, result ordering, pagination, rate limits, or auth requirements for a feed tool.

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?

A single front-loaded sentence with no filler. The scope constraint (read-only) and the data source lead the sentence, which is exactly what an agent needs first.

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 read-only feed with three optional parameters and no output schema, the description covers the essentials of what the tool returns conceptually. However, with no output schema it should still hint at the shape of returned trade records and the meaning of 'recent'.

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%, so the description must compensate. It clarifies the 'source' concept (smart-money vs KOL wallets) but is silent on the 'side' buy/sell filter and the 'limit' cap, leaving two of three parameters unaddressed.

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 verb and resource: a read-only feed of recent trades, scoped to GMGN-tagged smart-money/KOL wallets. The purpose is clear and distinct from token/launch/signal siblings, but it never names a sibling to differentiate itself explicitly.

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?

There is no when-to-use, when-not-to-use, or alternative guidance. The agent must infer usage purely from the noun phrase 'recent trades by smart-money or KOL wallets' with no routing help against the other nine Robinhood tools.

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