list_vendor_roles

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

No annotations are provided, so the description must disclose behavior. It only mentions the endpoint and the fact that it lists roles, omitting details about pagination, authentication, ordering, or response format. The GET method and list wording imply a read-only query, but this is minimal and under-specified compared to what an agent needs.

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 line, front-loaded with the operation and endpoint. It avoids unnecessary detail, but is arguably too terse; however, it is appropriately sized for a simple list endpoint.

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?

The tool lacks an output schema and annotations, so the description should compensate by explaining return values and behavioral nuances. It only states the endpoint and purpose, failing to mention how pagination works or what the response contains. This is incomplete for agent decision-making.

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 coverage is 100%, with both page and limit having descriptions in Chinese ('頁碼 (1-based)' and '每頁筆數'). The tool description adds no additional parameter semantics beyond the schema, so the baseline score of 3 is appropriate.

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 '取得廠商角色列表' (Get vendor role list) and includes the endpoint GET /v1/vendors/roles, clearly indicating a specific verb and resource. However, it does not explicitly distinguish this tool from the many sibling list_* tools, so it falls short of a 5.

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?

No guidance is provided on when to use this tool versus alternatives like list_vendor_users or list_vendor_actions. The description simply names the operation, leaving the agent to infer usage solely from the tool name and endpoint.

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