verify_product

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

No annotations are provided, so the description must independently disclose behavior. It reveals that the tool is read-only (verify) and returns specific fields, but it does not mention error handling for nonexistent products, authentication requirements, or side effects.

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 a single sentence that is front-loaded with the tool's purpose. Every word is meaningful, and there is no redundancy or fluff.

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?

Despite the absence of an output schema and annotations, the description sufficiently sets expectations by listing the returned fields (name, origin, owner, registration date). For a simple tool with one parameter, this is complete.

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% with one parameter. The description adds value beyond the schema by providing an example format (e.g., 'LOT-20260315-A1B2C3') and clarifying that the parameter is a product/batch ID.

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 uses the specific verb 'verify' and resource 'product' on the HimiTrace blockchain. It clearly states what the tool does (existence check + info retrieval) and distinguishes from the sibling 'check_product_exists' which likely only checks existence.

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 implies usage for verifying existence and retrieving basic info. While it doesn't explicitly state when not to use or name alternatives, the context of sibling tools provides enough differentiation for an AI agent.

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