getBalanceSheetStatementAsReported

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint. The description adds that data comes 'directly from official filings', which confirms the source. No additional behavioral details like pagination, rate limits, or response size are provided, but the description does not contradict annotations.

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?

Two sentences, no extraneous information. The first sentence is slightly redundant ('As Reported Balance Statements API' mirrors the tool name), but overall efficient and front-loaded with the key purpose.

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?

The description explains the return content (balance sheet items from filings) but doesn't address how parameters like limit and period affect the output or mention response format. For a simple tool with no output schema and adequate annotations, this is minimally complete but lacks guidance for effective use.

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 coverage is 100%, so baseline is 3. The description mentions 'assets, liabilities, and equity', adding context about the return data but not about the parameters themselves. No additional parameter semantics beyond what the schema provides.

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 it provides balance sheets 'as reported by the company' from official filings, differentiating from standardized or growth variants among siblings. The verb 'access' combined with specific resource makes the purpose clear, though it doesn't explicitly contrast with similar tools.

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 guidance on when to use this tool versus the many balance sheet alternatives (e.g., getBalanceSheetStatement, getBalanceSheetStatementGrowth). No mention of prerequisites or exclusion criteria, leaving the agent to infer context from the tool name alone.

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