getIndustryPerformanceSummary

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

Annotations (readOnlyHint, idempotentHint, openWorldHint) already indicate a safe, idempotent read. The description adds that it analyzes value over a period but does not disclose aggregation details or return behavior. It 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?

The description is two sentences and fairly concise, though the first sentence restates the tool's name. It front-loads the purpose, but could be slightly 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 lacks information about the return format or what the 'overview' contains. Since there is no output schema, the description should compensate, but it does not explain the output structure or fields.

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 covers 100% of parameters with descriptions. The description does not add new meaning beyond implying the period is defined by year and quarter, so baseline 3 is appropriate.

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 an overview of industry financial performance over a specific period, using a specific verb and resource. However, it does not distinguish from sibling tools like getHistoricalIndustryPerformance or getIndustryPerformanceSnapshot, which may have similar purposes.

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 gives a general context for investors and analysts but does not specify when to use this tool over alternatives like getHistoricalIndustryPerformance or getIndustryPerformanceSnapshot. No exclusions or comparisons are provided.

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