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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does reveal that the tool returns implied price movement and percentage differences for listed companies, which is useful. However, it omits details about response format, data coverage scope, pagination, or any limitations of the bulk operation.

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 with no filler, and the primary action is front-loaded. The phrase 'for all listed companies' is slightly ambiguous but not redundant, making it an efficient, well-structured summary.

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?

With no output schema, the description should clarify return values, and it does mention implied price movement and percentage differences. However, it does not detail the structure of the DCF valuation data or how 'all listed companies' is scoped, leaving some ambiguity for a tool with no parameters.

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 input schema has zero parameters and 100% schema coverage, so there is no parameter behavior to explain. The description's mention of 'multiple symbols' is slightly inconsistent with the empty schema, but the baseline for a zero-parameter tool is 4, and the description does not need to compensate for missing parameter details.

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 discounted cash flow (DCF) valuations for multiple symbols in one request, using a specific verb and resource. It distinguishes itself from the sibling getDCFValuation by emphasizing the bulk aspect, making the purpose immediately understandable.

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 when DCF valuations are needed for many symbols at once ('quickly retrieve' and 'multiple symbols in one request'), but it does not explicitly compare with alternatives like getDCFValuation or state when not to use this tool. There are no named exclusions or alternative recommendations, so usage guidance is only implicit.

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