getBalanceSheetGrowthBulk

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

The annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is covered. The description adds only that the data is growth-oriented and multi-company; it does not disclose the company universe, result size, pagination, or other bulk-specific behavior that an agent would need to invoke it confidently.

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 definition is a single front-loaded sentence that states the resource and scope efficiently. The trailing 'enabling detailed analysis' clause is mildly promotional but does not obscure the tool's 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 is adequate for a two-parameter bulk read endpoint whose annotations cover safety and whose schema documents both inputs. However, for a bulk financial data tool with no output schema, it omits important context such as whether all companies are returned and how this differs operationally from the singular growth endpoint.

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 description coverage is 100%, with clear descriptions for year and period. The description reinforces the temporal dimension ('changed over time') but adds no new syntax or meaning beyond what the schema already 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 states a specific verb and resource: retrieve balance sheet growth data across multiple companies. The word 'Bulk' and 'multiple companies' distinguish it from the singular growth endpoint, though it does not explicitly name the sibling alternatives.

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 description implies usage for bulk, multi-company analysis through phrases like 'Bulk API' and 'across multiple companies.' It does not explicitly state when to choose this over getBalanceSheetStatementGrowth or getBalanceSheetStatementsBulk, so guidance remains inferred rather than direct.

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