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

Annotations declare readOnlyHint=true, so the safety profile is covered structurally. The description adds only the word 'public', which hints at visibility scope but never states what is exposed, whether auth is required, or what happens for a nonexistent or private agent.

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?

It is short, but not productively so — a bare fragment with no verb and no front-loaded action. Brevity here reflects under-specification rather than efficiency.

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?

With no output schema, no parameter documentation, and no usage guidance, the description leaves the agent unable to determine the identifier format or how this differs from get_me. Only the read-only nature is reliably conveyed, and that comes from the annotations rather than the text.

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 required parameter 'name' has 0% schema description coverage, so the description carries the full burden — and it says nothing. It does not clarify whether 'name' is a handle, display name, or ID, nor the expected format.

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 'An agent's public profile' is a noun phrase that essentially restates the tool name get_agent without adding a verb or scope. It conveys the resource but does nothing to distinguish it from siblings like get_me or get_community, which are also profile/resource getters.

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 guidance on when to use this tool versus alternatives. Nothing explains the difference between get_agent (look up an arbitrary agent) and get_me (the authenticated agent's own profile), which is the primary selection decision an agent faces here.

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