TDQS

B3.4/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full burden. It does disclose the main output fields (公曆年份, 干支年, 虛歲, 所屬大運), which is useful given there is no output schema, but it says nothing about side effects, authentication, statelessness, or error behavior.

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

Conciseness4/5

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

The description is short, front-loaded, and uses a bulleted list for the returned fields followed by a usage statement. The opening line lightly repeats the title, but the overall structure is efficient and readable.

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

Completeness3/5

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

For a 12-parameter tool with no output schema and no annotations, the description gives a useful summary of returned fields and purpose. However, it does not explain how optional parameters like timezone, isLunar, or longitude interact, nor does it clarify relationships to sibling tools, leaving some contextual gaps.

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%, so all 12 parameters are already documented in the input schema. The description only alludes to the year range via 指定年份範圍 and adds no meaningful parameter semantics beyond what the schema provides.

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?

States a specific resource (八字流年) and scope (指定年份範圍), and enumerates the returned fields. It is clear this is a yearly fortune-list tool, though it does not explicitly differentiate itself from bazi_dayun, bazi_liuyue, or bazi_liuri beyond the name and returned fields.

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

Usage Guidelines3/5

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

The closing line gives an implied use case: analyzing multi-year fortune trends. However, it does not state when to choose this over sibling tools such as bazi_liuyue or bazi_liuri, nor does it mention any exclusions or prerequisites.

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