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

With no annotations, the description must disclose behavioral traits. It mentions the authentication requirement, but it does not state that the operation is read-only (though implied by 'Get'), nor does it describe the response structure, potential errors, or any side effects. This leaves the agent with limited information about what to expect.

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, concise sentence that front-loads the core action and resource. It contains no unnecessary words and is appropriately sized for a simple no-parameter getter.

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 absence of an output schema, the description should describe the return value. It only says 'Get your company's perks/benefits', which implies a list but does not explain the format, fields, or any pagination. For a simple tool, some detail about the response would be expected. The authentication note is useful, but the lack of return information makes it incomplete.

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, so the baseline is 4. There is nothing to explain about parameters, and the schema correctly shows an empty properties object. The description does not need to elaborate on parameter semantics.

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 verb 'Get' and the resource 'company's perks/benefits' on Himalayas, distinguishing it from sibling tools like add_company_perk and remove_company_perk. It is specific and unambiguous about the tool's purpose.

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 the tool is for retrieving perks, but it does not explicitly mention when to use it versus alternatives like add_company_perk or remove_company_perk. It provides the context that employer authentication is required, which hints at eligibility, but lacks explicit guidance on selection criteria.

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