furunavi_auth_status

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

No annotations provided; description only states purpose. It does not disclose return format, side effects (e.g., network calls), or what happens if session is not saved. Lacks details that would help an agent predict behavior.

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?

Single sentence, front-loaded, no wasted words. Highly concise and clear.

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?

For a simple tool with no parameters or output schema, the description is adequate but leaves out expected output format or error conditions. Could be more helpful by describing the return value (e.g., boolean, status text).

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?

No parameters in schema, so description does not need to add parameter details. Baseline for 0 parameters is 4; the description correctly implies no arguments 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 checks the login session save status of Furunavi (furunavi_auth_status). It uses a specific verb (確認します) and resource, distinguishing it from siblings like furunavi_auth_login and furunavi_auth_clear.

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 explicit guidance on when to use this tool versus siblings. While the purpose implies it is for checking session status before/after login/clear operations, there is no mention of prerequisites or context.

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