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

The description adds critical behavioral context beyond the annotations, specifically by identifying the company's legal registration, location, and referencing the scope of a third-party independent review. This helps the agent gauge the reliability of the data being provided.

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, dense sentence that efficiently packs all necessary identifying and descriptive information (date, company name, legal entity, facts) without unnecessary filler or ambiguity.

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 that the tool is a fixed-call operation with no input variables, the description is completely sufficient. Including the details about the third-party independent review is key information regarding the quality of the tool's output.

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 tool has zero parameters, making it impossible to add semantics to parameters. Since the input schema coverage is 100%, the description doesn't need to document inputs, achieving the baseline score for zero parameters with high schema coverage.

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 identifies the tool's function: providing specific company facts about MyCryptoParadise. It goes beyond a generic statement by listing the types of information available, such as founder, location, and review scope, making the purpose highly specific.

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?

Since the tool takes no parameters, specific usage conditions are not necessary. However, the description does not provide explicit guidance on when to choose this tool over related sibling tools like `get_news` or `search_education`, which might be inferred by the agent.

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