getStockGradeLatestNews

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

Annotations already indicate readOnlyHint, idempotentHint, and openWorldHint. The description adds value by explaining that results include links to original sources, stock price movements, grading firm actions, and market sentiment shifts, which are behavioral traits beyond the annotation scope.

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 front-loaded purpose. It is reasonably concise without unnecessary words, though slightly verbose in the second sentence. It earns its place by explaining value and source credibility.

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 no output schema, the description provides sufficient context about the content returned (news links, price movements, sentiment). It adequately covers the tool's functionality for a simple read-only API with two optional 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?

Schema description coverage is 100%, so the schema already documents both parameters (page and limit). The description does not add any further meaning or constraints about the parameters, resulting in no additional value beyond the schema.

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 provides the latest stock rating changes and analyst ratings news with links to sources. It uses specific verbs like 'provides' and 'track', and identifies the resource as 'latest stock rating changes'. However, it does not explicitly differentiate from sibling tools like getStockGradeNews or getStockGrades, which limits distinction clarity.

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?

There is no guidance on when to use this tool versus alternatives such as getStockGradeNews, getStockGrades, or getStockGradeSummary. The description only explains what the tool does without providing context for selection or exclusions.

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