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 does not explain pagination behavior, default sorting, how 'latest' is defined, or any rate limits. The description is a high-level summary without operational details, which is a significant gap for a data retrieval 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?

The description is two sentences but includes fluff like 'Stay informed' and 'with the FMP Equity Offering Updates API', which are not essential. While it is not overly long, it could be more direct. The core information is present but not maximally lean.

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 optional parameters and no output schema, the description provides a general sense of the output (new share issuances, exempt offerings, amendments). However, it omits details such as default sort order, time window, or whether pagination is required. The description is minimally viable but lacks completeness for an agent to fully predict behavior.

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?

The input schema already provides descriptions for all 3 parameters (cik, page, limit), so the schema coverage is 100%. The description does not add any additional meaning or context for these parameters beyond what the schema states. The baseline of 3 is appropriate.

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 states the tool's function: retrieving latest equity offerings, including new share issuances, exempt offerings, and amendments. Although it does not explicitly differentiate from sibling tools like getEquityOfferingsByCIK or searchEquityOfferings, the 'latest' scope is implied. The verb is specific enough to convey the action.

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 guidance on when to use this tool versus alternatives. The description does not mention related tools or conditions under which this tool is preferred. The user is left to infer appropriate use cases from the name and schema.

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