Corporate actions in progress

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

With no annotations provided, the description carries the behavioral disclosure burden. It clarifies that the data is published by Robinhood and associated with Stock Tokens, which implies a read-only listing. Still, it does not state whether the response is a flat list, whether only in-progress actions are included, or what fields the data contains.

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 compact sentence with key domain terms front-loaded and no filler. The relationship 'each tied to its token' adds useful meaning without bloating the text.

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 parameterless endpoint, the description conveys the essential scope: Robinhood-published corporate actions for Stock Tokens. It is not exhaustive about the exact return shape or the 'in progress' aspect from the title, but the low complexity makes the current description largely sufficient for invoking the tool.

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 schema description coverage is 100% vacuously, so the baseline of 4 applies. The description's token-relationship context is useful but not necessary for parameter understanding.

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 identifies a concrete resource: corporate actions such as dividends and splits that Robinhood has published for Stock Tokens. It is specific and scoped, but it lacks an explicit verb like 'lists' or 'returns' and does not explicitly distinguish itself from sibling tools such as events or history.

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 phrasing 'for Stock Tokens' and 'each tied to its token' implies this tool should be used when an agent needs token-specific corporate action data. However, there is no explicit when-to-use guidance, exclusions, or reference to alternative sibling tools.

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