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

No annotations are provided, so the description must disclose behavior. It reveals the reference date (113-07-01), the 11 situations, and that it reports prescription eligibility and process, but does not state that it is a read-only lookup, its return format, or any limitations. This is partial transparency.

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 dense sentence with parenthetical enumerations, front-loading the topic before listing values. It is information-dense with no redundant phrases, though a bulleted list would improve scannability.

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?

With no annotations and no output schema, the description carries the burden. It explains what the tool checks and describes the content of the return (situations, prescription eligibility, process). It does not specify output format or edge cases, but it is sufficient for a low-risk eligibility lookup.

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 0% and the single 'situation' parameter has no enum or description in the schema. The description fully enumerates all 11 allowed values with Chinese/English explanations and states that omitting the parameter returns all situations, fully compensating for the schema gap.

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 that the tool checks Taiwan telemedicine eligibility, including 11 special situations, whether prescriptions can be issued, and the process, so the resource and scope are clear. It does not differentiate from siblings, but the siblings are unrelated wellness tools. A concise purpose verb is absent but the overall purpose is 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?

There is no explicit when-to-use guidance or comparison to alternatives. The description explains the situation parameter values and that omitting it lists all situations, which helps invocation but not tool selection. It lacks conditions for calling this tool versus other tools.

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