TDQS

A4.5/5.0
Behavior4/5

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

No annotations are provided, so the description carries full burden. It discloses that it queries specific market data fields and the data source. It does not mention authorization, rate limits, or whether the operation is read-only, but the context implies it is a read query. Additional detail on return structure would improve transparency.

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 a single sentence that efficiently conveys the purpose, key data fields, and dependency on another tool. It is front-loaded and contains no extraneous information.

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

Completeness5/5

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

Given the single required parameter and lack of output schema or annotations, the description provides sufficient context for correct usage. It explains what data is returned and how to obtain the input value, making the tool's functionality clear.

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

Parameters4/5

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

The input schema already describes the parameter with a pattern and description. The description adds value by explicitly linking theme_code to the output of get_theme_groups, providing contextual meaning beyond the schema.

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

Purpose5/5

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

The description clearly states the tool retrieves constituent stocks and market prices for a specific theme group, including specific fields like current price, change, change rate, volume, and period return. It also identifies the data source (kiwoom ka90002) and explains how to obtain the theme_code, which distinguishes it from sibling tools.

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?

The description explains that theme_code must come from get_theme_groups, providing clear context for usage. However, it does not explicitly contrast with sibling tools or state when to use this tool versus alternatives like get_stock_price or get_stock_chart.

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