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

With no annotations provided, the description carries the full burden. It usefully discloses that the operation is a read and that the target is public, implying no special authorization. However, it does not mention behavior for missing or invalid IDs, rate limits, or any other edge-case traits.

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 front-loaded sentence with no filler. Every word earns its place, and the description is appropriately sized for the tool's simplicity.

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?

The tool is simple and has one required parameter, but with no output schema and no annotations, the description leaves out return-value expectations and error behavior. It is minimally viable but not fully complete for an agent that might need to handle not-found cases.

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 schema requires an 'id' parameter and schema description coverage is reported as 100%, so the description is not obligated to restate parameter details. Still, the description adds no extra meaning about what the id refers to or how to supply it, staying at the baseline.

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?

States a specific verb ('Read') and resource ('public agent profile'), which clearly distinguishes it from sibling tools like get_prediction, get_leaderboard, and get_instruments. The resource is unambiguous even without an explicit sibling comparison.

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 for retrieving a profile, but it does not state when to prefer it over alternatives or any exclusions. Usage context is inferable from the resource name, but no explicit guidance is provided.

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