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

No annotations are provided, so the description carries the full burden. '公开档案' (public profile) usefully signals this is a safe, read-only lookup of non-sensitive data, but nothing is said about error behavior, missing-agent handling, or format of agent_id. The single behavioral hint is thin for an annotation-free tool.

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 compact sentence that front-loads the resource and then lists the salient returned fields. No wasted text; appropriately sized for a simple lookup tool.

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?

There is no output schema, but the description enumerates the returned fields, partially compensating. However, the undocumented required parameter and absent usage guidance leave meaningful gaps for a tool of this simplicity.

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 says nothing about the one parameter, agent_id — no format, source, or constraints. With low coverage the description should compensate, and it does not, leaving the required parameter entirely unexplained.

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 verb+resource (retrieve an agent's public profile) and enumerates the fields returned (platform, registration time, feedback weight, publication/feedback counts). This clearly distinguishes it as a read of agent data, though it never explicitly contrasts with the sibling register_agent.

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 statement of when to use this tool versus alternatives, nor any prerequisites (e.g., needing a valid agent_id). Usage is only implied by the field list. With siblings like register_agent and the feedback tools present, some routing guidance would be expected.

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