Behavior2/5

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 mentions '리스크 분석' (risk analysis), implying a read-only or analytical operation, but doesn't disclose behavioral traits like data sources, output format, rate limits, or error handling. This is inadequate for a tool with no annotation coverage.

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 a single, efficient sentence in Korean that conveys the core purpose without unnecessary words. It's appropriately sized and front-loaded, though it could be slightly more structured for clarity.

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

Completeness2/5

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

Given no annotations, no output schema, and a vague purpose, the description is incomplete. It doesn't explain what the tool returns (e.g., risk metrics, reports), how the analysis is performed, or any limitations, making it insufficient for effective agent use.

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 the schema already documents all three parameters (corp_code, bgn_de, end_de) with descriptions. The description adds no additional parameter semantics beyond what's in the schema, resulting in the baseline score of 3.

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

Purpose3/5

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

The description states the tool analyzes risks related to stock exchange/transfer decisions for complete subsidiary formation and governance restructuring, which provides a general purpose. However, it's vague about the specific action (e.g., retrieving data, generating reports) and doesn't clearly distinguish from sibling tools like 'get_stock_exchange_report' or 'get_stock_total' that might handle similar data.

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

Usage Guidelines2/5

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

No explicit guidance is provided on when to use this tool versus alternatives. The description mentions analysis but doesn't specify prerequisites, context, or comparisons to siblings, leaving the agent with no usage direction beyond the implied purpose.

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