TDQS

A3.8/5.0
Behavior3/5

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

No annotations are provided, so the description must carry the full behavioral burden. It lists return fields, implying a read-only query, but it does not state that the tool is side-effect-free, does not mention any authentication or rate-limit behavior, and does not clarify that it merely computes data. Minimum viable but with clear gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short, front-loaded, and uses a bullet list to enumerate return fields efficiently. Every sentence earns its place; no redundant or vague filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, so the description correctly enumerates the returned fields. It also supplies a usage context. It does not, however, explain how it relates to sibling tools or disclose any behavioral traits, leaving minor gaps for a complex astrology tool with 11 parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the description adds no meaning for any of the 11 input parameters (year, month, day, hour, gender, etc.). Baseline 3 is appropriate when the schema fully documents parameters and the description does not supplement them.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the specific resource (紫微大限), states it returns decade cycles, and enumerates the returned fields (起止虛歲, 公曆年份, 宮位名稱, 主星配置, 四化). This clearly distinguishes it from siblings like ziwei_liunian or ziwei_xiaoxian, but it never explicitly contrasts those alternatives, so it falls short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides a clear use context: '用於了解人生各階段的運勢大框架' (to understand the broad framework of life-stage fortunes). However, it gives no explicit when-not conditions or named alternatives for other Zi Wei tools, so it lacks the exclusion guidance needed for a 5.

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