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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, covering the safety and side-effect profile. The description adds that results carry research order, usage instructions, and source-verification info, which is useful since no output schema exists, but it discloses nothing about result volume, pagination, or the closed-world data scope.

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?

Two compact sentences with the domain scope and delivered content front-loaded; no filler or restatement of the title. It is appropriately sized, though the second sentence's list of deliverables is slightly list-like rather than prioritized.

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 read-only, single-parameter list tool with no output schema, the description does establish domain scope and the nature of returned content, which is the minimum needed. However, the one parameter that governs behavior and any pagination/limit expectations are left entirely unexplained, leaving the definition adequate but with clear gaps.

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 description coverage is 0% and the sole 'q' parameter (maxLength 160, optional) is never referenced in the description. The verb '찾습니다' weakly implies a search input, but no meaning, syntax, or matching behavior is supplied to compensate for the empty schema.

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?

States a clear verb ('찾습니다') and resource ('조사 묶음') and enumerates the five domains covered (semiconductors, shipping, raw materials, rates/prices, virtual assets), plus the accompanying materials. It is distinguishable from most siblings, but never explicitly contrasts itself with the singular get_research_pack, so it falls short of the sibling-differentiation bar for a 5.

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?

There is no explicit when-to-use guidance or alternative named, despite get_research_pack being an obvious sibling to route against. The enumeration of domains and contents implies a discovery use case, but the agent must infer when to pick this over the singular retrieval tool.

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