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

Annotations already cover the safety profile (readOnlyHint, idempotentHint, destructiveHint=false), so the description only needed to add context. It does not disclose that openWorldHint implies an external/third-party lookup, whether multiple reports can be returned for one product, or whether results can be empty or restricted — all behaviorally relevant for this tool.

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?

A single twelve-word sentence, front-loaded with the verb and resource. Nothing is wasted, but there is very little content to structure.

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?

With no output schema, no parameter descriptions, and an open-world data source, the description should say what a lab report record looks like and whether multiple reports are returned. Instead it stops at restating the title, leaving the agent under-informed about the response.

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%, so the single bare "query" string param would be opaque on its own. The description compensates by telling the agent the query should be a lot number or product identifier, but provides no format, casing, or ID conventions.

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 pairs a specific verb ("Read") with a specific resource ("lab reports") and states the lookup key (lot number or product). This is clearly distinguishable from the e-commerce siblings like build_cart or search_products, though it does not explicitly name an alternative.

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?

It hints at the acceptable input (lot number or product) but never says when to prefer this tool over get_product or search_research, or what happens if no report exists. Usage is only inferable from the verb.

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