Read-only

Search for a company by name or stock code to retrieve its unique corporate code (corp_code), required as input for other disclosure tools. Supports filtering by listing status and setting result limits.

Behavior4/5

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

Description adds behavioral context beyond annotations by explaining that it is a lookup tool returning corp_code and serving as a preliminary step. Annotations already declare readOnlyHint=true, so no contradiction; description complements well.

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?

Two sentences, front-loaded with the key purpose, and every word adds value. No redundancy or wasted text.

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?

With output schema present, description does not need to detail return values. It covers purpose, usage, and prerequisites sufficiently, leaving parameter details to schema.

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 parameters are well-documented. The tool description does not add additional meaning to parameters beyond what schema provides, meeting baseline for high coverage.

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?

Description clearly states it searches for corp_code by company name or stock code, which is a specific verb-resource combination. It also distinguishes itself from siblings by noting it is a prerequisite for other tools needing corp_code.

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?

Explicitly says 'When you need corp_code from other tools, first search the company with this tool,' providing clear indication of when to use it. No explicit when-not or alternatives, but context is sufficient.

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