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

No annotations provided, so the description carries the full burden of behavioral disclosure. It says nothing about what the tool returns (structured data? text? steps?), whether it's a lookup or generator, or any behavioral traits. For a zero-parameter tool with no annotations, this is a significant gap.

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 concise sentence with no waste. It front-loads the technique names efficiently, though the framing is more like a subject listing than an action statement.

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, no output schema, and zero parameters, the description should do more heavy lifting — e.g., clarify the return format or scope. It only lists topics, leaving the agent unable to predict the response shape or use context beyond the sibling set (wellness tools).

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 tool has 0 parameters, so per the rubric the baseline is 4. The description correctly implies no inputs are needed, referencing only content topics rather than parameters.

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 names specific breathing techniques (方塊呼吸, 4-7-8, 共振呼吸, 生理嘆息) and mentions timing/application, implying it provides relaxation methods. However, it's not a clear verb+resource statement — it reads like a topic label rather than stating what the tool actually returns or does. Compared to siblings like score_gad7 (a clear action), the purpose is vaguer.

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. The mention of 適用時機 (applicable timing) hints that timing guidance exists in the content, but the description itself gives no when/when-not or alternatives.

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