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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds useful scope by noting the search is limited to the ValuEdge-supported security universe, but it does not describe result ranking, limits, or matching behavior.

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 front-loads the usage condition. Every sentence contributes either the triggering scenario or the important universe limitation.

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?

Given the low complexity, rich annotations, and the presence of an output schema, the description covers the essential context: when to use it, what it resolves, and its closed universe. Minor gaps remain around matching behavior and result presentation, but return values are handled by the output schema.

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?

With only one required parameter and 0% schema description coverage, the description partially compensates by saying the query is an ambiguous company name or ticker. It does not clarify matching behavior, partial input support, or ticker formatting, so it adds meaning but not enough to fully cover the schema gap.

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: searching securities to resolve an ambiguous company name or ticker. It distinguishes the tool from valuation/comparison siblings by placing it before those steps, though it does not explicitly name the 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?

It gives clear usage guidance: use this when the user supplies an ambiguous company name or ticker and you need to resolve it before valuation or comparison. It does not explicitly state when not to use it or name alternative sibling tools, which keeps it from a 5.

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