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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It mentions that the output includes a short summary and a link to the service page, which gives some insight into what the tool returns. However, it does not state any side effects, access requirements, or whether the data is static or dynamic. For a simple read-only listing, this is adequate but not rich, warranting a mid-range score.

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 sentence that front-loads the core purpose (listing 12 services with summary and link) and then provides usage context. Every part serves a function, with no redundancy or fluff. It is appropriately concise and well-structured.

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 tool's simplicity (no parameters, no output schema), the description is fully complete. It states what the tool returns (list of services, summary, link) and when to use it. There are no additional complexities like authentication or side effects that need explanation. The description covers all necessary information for an agent to select and invoke the tool correctly.

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, and the schema coverage is 100% (empty properties). Per the rubric, the baseline for 0 parameters is 4. The description does not add parameter-specific details because there are none, but it provides contextual information about the content, which is sufficient. No deduction needed.

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's purpose: listing the 12 services offered by CODENIVERSE, with a summary and link. The verb 'list' is explicit, and the resource (services) is well-defined. It also differentiates from siblings like get_company_profile or get_article by focusing specifically on service offerings.

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 explicitly states when to use the tool: 'use when the user asks what work this company accepts or what can be hired for.' This is clear usage guidance. However, it does not mention when not to use it or suggest alternative tools, so it falls short of a perfect score per the rubric.

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