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

With no annotations provided, the description carries full burden for behavioral disclosure but provides minimal information. It mentions the available actions but doesn't describe what each action does behaviorally (e.g., whether 'delete' is permanent, whether 'create' requires specific permissions, what format results return, or any rate limits). The description doesn't contradict annotations since none exist, but it fails to provide essential behavioral context for a multi-action tool with 16 parameters.

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 reasonably concise with two sentences that cover the tool's purpose and available actions. The action list is efficiently presented. However, the Korean text followed by English action list creates minor structural inconsistency, and the description could be more front-loaded with critical information about the tool's primary use cases.

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?

For a complex tool with 16 parameters, no annotations, no output schema, and multiple actions, the description is inadequate. It doesn't explain the relationships between actions and parameters, doesn't describe return formats, and provides no behavioral context. The description fails to address the tool's complexity, leaving significant gaps in understanding how to use it effectively.

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?

With 56% schema description coverage, the description adds minimal value beyond what the schema provides. It mentions the available actions but doesn't explain when each parameter is required or how they interact with different actions. The schema already documents most parameters adequately, so the baseline of 3 is appropriate, but the description doesn't compensate for the 44% coverage gap in parameters like 'companyName', 'announcementId', or 'memo'.

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?

The description clearly states the tool's purpose: managing government support benefit history with specific operations like business selection registration, expense addition, and milestone recording. It distinguishes itself from siblings by focusing on historical data management rather than eligibility checking, searching, or document generation. However, it doesn't explicitly contrast with similar-sounding tools like 'searchGovernmentSupport'.

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?

The description provides no guidance on when to use this tool versus alternatives. While it lists available actions, it doesn't explain when to choose 'list' versus 'get', or when to use this tool instead of sibling tools like 'searchGovernmentSupport' or 'checkEligibility'. There's no mention of prerequisites, dependencies, or typical workflow contexts.

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