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

No annotations are provided, so the description carries the full behavioral burden. It does disclose that the response includes both the full post text and its replies, which is useful, but says nothing about error behavior for an invalid id, permissions, or rate limits.

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?

A single short sentence with the site tag front-loaded and no wasted words. Appropriately sized for a one-parameter lookup, though the extreme brevity is part of why other dimensions are thin.

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 output schema, the description helpfully names the returned content (full text and replies). However, the sole parameter's semantics and any usage context are missing, leaving gaps for a tool with zero annotation coverage.

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 schema has one parameter (id) with 0% description coverage, so the description must compensate and it does not. It never explains what the id is, its format, or where to obtain it (e.g., from list_taiwan_posts).

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?

States a specific verb (取得/get) and resource (一篇台灣真人心得全文與回覆), including the return content (full text plus replies). It is distinguishable from voices__list_taiwan_posts and voices__search_human_opinions, though it doesn't explicitly name them.

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?

Usage is only implied: retrieving a single post by id, presumably after listing or searching. There is no explicit when-to-use, when-not-to-use, or reference to the sibling list/search tools that would route an agent here.

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