get_similar_targets

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

The readOnlyHint annotation already signals a safe read operation, and the description adds the concept of 'association profiles' but does not elaborate on the similarity metric, threshold semantics, or pagination behavior. It provides some context but no significant behavioral detail beyond the annotation.

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 concise, front-loaded sentence with no filler. Every word contributes to defining the tool's purpose.

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?

An output schema exists and readOnlyHint is set, but the description does not explain the meaning of size and threshold, nor the nature of 'association profiles'. For a similarity tool, understanding the similarity measure and parameter effects is crucial, so the description is only partially 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 description coverage is 0% and the description does not mention parameters. While entity_id is self-explanatory, size and threshold are ambiguous (e.g., what does threshold mean? inclusive/exclusive?), and the description offers no clarification. The parameter names provide partial hints but are insufficient.

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 clearly states the tool's function: 'Identify targets with similar association profiles to the seed target.' It uses a specific verb ('Identify') and a specific resource ('targets'), and the phrase 'similar association profiles' distinguishes it from sibling tools like get_disease_similar_entities and get_drug_similar_entities.

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 the tool is used when you have a seed target and want to find similar targets, but it does not explicitly state when to use this over alternatives like get_disease_similar_entities or get_drug_similar_entities. No exclusions or alternative guidance is provided.

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