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, but it only states the action and resource. It does not describe return format, data scope, limitations, or any operational behavior. The word 'Get' implies read-only, but no further transparency is given.

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 sentence with no filler, efficiently conveying the core purpose. While it is under-specified, the conciseness dimension focuses on word economy and structure, and this earns a 4 due to its brevity and clarity.

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?

No output schema exists, and the description provides insufficient context about what constitutes 'key financial metrics', the structure of the response, or how recent_n affects results. Compared to the rich sibling context, this description is too minimal to be complete for an agent.

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?

Both parameters have descriptions in the schema, so the baseline is 3. The description does not add any additional meaning about the parameters, relying entirely on the schema for semantics.

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 retrieves key financial metrics from the three major financial statements, identifying the specific verb and resource. It differentiates itself from statement-specific siblings like get_balance_sheet but does not clearly distinguish from other metrics-focused siblings like getKeyMetrics or getFinancialRatiosTTM.

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?

No usage guidance is provided. The description does not mention when to use this tool over alternatives, nor does it give any exclusions. Given the large sibling list with overlapping functions, this is a significant gap for an agent selecting between tools.

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