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

The annotations already declare readOnlyHint=true, idempotentHint=false, and destructiveHint=false, so safety and mutation behavior are covered. The description adds useful detail about the returned resource fields, but does not discuss response shape, empty-result behavior, pagination, or failure modes.

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 one front-loaded sentence that immediately states the return type and target. The examples of origins, labels, evidence codes, dates, and URLs are useful but make the sentence somewhat long, without becoming structurally confusing.

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 lookup with one fully documented parameter and no output schema, the description explains the returned resource type and enumerates the main returned fields. It is nearly complete, though it could mention response format or error behavior.

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?

The single parameter is fully documented in the schema, including the 4-character PDB ID requirement. The description adds only that the lookup is for a PDB entry and does not provide additional format or constraint details beyond the 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?

The description states a clear verb and resource: it returns FunPDBe functional annotation resources for a given PDB entry. It also lists the kinds of fields returned, which helps distinguish it from generic annotation or entity tools, though it does not explicitly name a sibling 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?

Usage is only implied by the phrase 'for a given PDB Entry' and by the tool's focus on FunPDBe functional annotation resources. There is no explicit guidance on when to prefer it over related PDB annotation tools, and no exclusions or prerequisites are stated.

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