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

With no annotations, the description carries the full burden. It discloses auto-handling of pagination and service key, date range restrictions (1 month limit), and fetch_all behavior (collects all pages). However, it does not explicitly state read-only nature or auth requirements, though these are inferable from context.

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

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

The description is organized with paragraphs, bullet lists, and visual separators. While lengthy, every sentence adds value; the list of 20 operations is necessary for clarity. Could be slightly more compact, but well-structured for the complexity.

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

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

Given the complexity (many operations, no output schema, no annotations), the description is quite complete: covers usage, parameters, limitations, and points to a companion tool for details. Lacks explicit response format but that is delegated to get_g2b_operation_info.

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

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

Schema coverage is 100% (baseline 3). The description adds substantial value by explaining operation choices, providing common param keys, clarifying fetch_all, and noting num_of_rows max (999). It also directs users to a companion tool for exact parameter details, which is contextually helpful.

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

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

Explicitly states the tool queries '나라장터 사전규격정보서비스' and lists 20 specific operations with Korean descriptions, making the purpose unmistakable and fully differentiated from siblings.

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

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

Provides comprehensive usage guidance: how to specify operation and params, notes auto-handling of common parameters, recommends using get_g2b_operation_info for exact details, lists common query parameters, warns about date range limitations, and distinguishes PPSSrch operations for advanced search.

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