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

With no annotations, the description carries the full burden of behavioral disclosure, but it only provides a high-level purpose. It does not mention return format, data scope, pagination, rate limits, or any prerequisites, leaving significant behavioral aspects undisclosed.

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 and reasonably concise, but the trailing clause 'enabling detailed analysis of how financial positions have changed over time' adds little value. Overall, it is compact but could be tighter.

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 omits essential context: how the bulk selection works, what 'growth data' includes, and the output structure. With no output schema and no clarification of the company selection mechanism, the description is incomplete for agent decision-making.

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 descriptions cover 100% of parameters, so the baseline is 3. The description adds no specific parameter guidance and introduces ambiguity by mentioning 'multiple companies' while the schema only includes year and period, without explaining how companies are specified.

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 growth data across multiple companies' balance sheets, using a specific verb ('retrieve') and resource. It effectively distinguishes it from sibling tools like getBalanceSheetStatementGrowth (likely single company) and getBalanceSheetStatementsBulk (statements, not growth).

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 analyzing growth trends across multiple companies, but does not explicitly state when to use this tool versus alternatives. There are no exclusions or comparisons to other bulk/growth endpoints, leaving usage guidance implicit rather than explicit.

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