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

Annotations already declare readOnlyHint=true and openWorldHint=false. The description adds useful context beyond annotations by disclosing that diver names, emails, and user IDs are omitted and that verification is included, but it does not explain ordering, recency semantics, default limit behavior, or what 'verification' entails.

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 three short, front-loaded sentences with little waste. The purpose is stated first, followed by privacy and verification notes, though 'Includes verification' is vague enough that it slightly weakens the otherwise efficient 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?

For a simple read-only retrieval tool with no output schema, the description covers purpose and some data-handling context. However, it leaves meaningful gaps around the meaning of 'latest', how the limit parameter behaves, and what the returned condition reports contain beyond verification.

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 description must compensate for the two undocumented parameters. It does not mention the required slug or the optional limit parameter, nor does it explain acceptable slug format or how limit controls result count.

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 states a specific resource and return type: timestamped condition reports for a plate. It is clear enough to distinguish this from sibling suitability or site tools, though it does not explicitly name or contrast with any 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?

There is no explicit guidance on when to use this tool versus alternatives like check_suitability or get_site_plate. The description implies it retrieves latest conditions, but gives no conditions for use or exclusions.

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