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

No annotations are provided, so the description must reveal behavior itself. It mentions tracking changes over time and multiple companies, but it does not disclose output format, pagination, growth calculation methodology, or whether all companies are returned for the given year and period. This is a significant behavioral gap.

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 compact, consisting of two sentences that front-load the tool's purpose and then offer a context for use. It is efficient with no filler, although the first sentence repeats the tool name and the second sentence is somewhat promotional.

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?

With no output schema and no annotations, the description carries the full burden of explaining response semantics. It fails to describe the shape of the returned data, the meaning of growth, or the company coverage behavior, making it incomplete for an agent trying to reason about the tool's output.

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 schema provides descriptions for both required parameters, with year example and period options, so schema coverage is complete. The description adds no additional meaning about how the parameters affect results, and it does not clarify how multiple companies are selected given only year and period are accepted.

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 as retrieving bulk growth data for cash flow statements, with a focus on tracking changes over time across multiple companies. This verb-resource-scope structure distinguishes it from the single-company getCashFlowStatementGrowth sibling, though the exact nature of growth data remains slightly generic.

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 only usage guidance is that the API is ideal for analyzing cash flow growth trends of multiple companies simultaneously, which implies bulk scenarios. However, it does not explicitly name alternatives, exclusions, or prerequisites, leaving the when-not-to-use case unclear.

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