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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds meaningful behavioral context by explicitly restricting output to public profile information and excluding private statistics and owner personal data. It does not describe return fields or pagination, but the added privacy constraint is substantive.

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?

Two compact sentences, front-loaded with the tool's action and followed by a precise exclusion. Every sentence earns its place and there is no redundant phrasing.

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 single-parameter read tool with rich annotations and full schema coverage, the description gives adequate purpose and privacy scope. It does not explain what fields the public profile contains, and there is no output schema to compensate, but the annotations already carry the safety semantics. The definition is mostly 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?

There is one parameter, catId, with 100% schema coverage including a UUID pattern and description. The description mentions using a cat UUID, which aligns with the schema but adds no format or semantic detail beyond what the schema already provides. The baseline for fully covered parameters is 3.

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 action and resource: retrieves public profile information using a cat UUID. It clearly excludes private statistics and owner personal data, which sharpens the resource boundary. However, it does not name or directly contrast with sibling tools like get_public_post or search_public_content, so the sibling differentiation is left implicit.

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 defines a clear negative scope: it does not provide private record statistics or owner personal information. This tells the agent when not to use the tool for private data, which is useful context. It stops short of naming alternative tools or giving positive when-to-use cues, so it is short of the top mark.

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