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

The annotations provide no useful positive behavioral hints (all false), and the description does not disclose any behavioral traits beyond the core function. It does not mention side effects, permissions, rate limits, or any effects on state. There is no contradiction, but the description fails to expand on 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?

The English description is concise (two sentences) and front-loaded with the purpose. However, the Japanese sentence repeats the same information in English, adding unnecessary length for an English-speaking agent. Still, it's compact overall.

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 low complexity (two optional parameters) and presence of an output schema, the description sufficiently covers usage and parameter decisions. It doesn't describe return values, but the output schema covers that. The description could mention prerequisites, but none are apparent.

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%, so the schema fully documents both parameters. The description adds a minor nuance: both parameters can be omitted when choosing is burdensome, extending the schema's note for state to locale. This is a slight improvement but not substantial, keeping the score at baseline 3.

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: retrieve a free 60-second support response, optionally using a state hint. This is specific and matches the title, but it does not explicitly differentiate from sibling tools like one_minute_akari or list_one_minute_states.

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 provides clear usage context: use when a state hint is already available, and omit parameters when choosing is burdensome. It does not explicitly mention when not to use it or alternatives, but the condition 'state hint is already available' implies a scenario.

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