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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Public information' suggests a read-only, non-sensitive operation, which is a useful signal. But it does not explicitly state whether there are side effects, authentication requirements, or what the return format looks like. For a simple zero-parameter info tool, this is acceptable but not rich.

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 a single sentence with no wasted words. It front-loads the action ('Return public information') and immediately states the purpose ('required to discover AgentMesh'). Every word earns its place, and the structure is optimal for such a simple 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?

Given the tool's low complexity (zero parameters, no output schema, no sibling tools), the description is reasonably complete. It tells the agent what the tool does and why it exists. However, it could specify the nature of the 'public information' (e.g., endpoints, capabilities) to be fully self-contained, though such detail may be unnecessary for a discovery bootstrap call.

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 tool has zero parameters, so the baseline is 4. The schema already exhaustively documents the empty parameter set, and the description adds no parameter-specific meaning because there are none to describe. This is appropriate for the tool's simplicity.

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 identifies the tool's function: returning public information needed to discover AgentMesh. It uses a specific verb ('Return') and names the resource ('public information required to discover AgentMesh'). While it doesn't list the exact contents of that information, it is not tautological and is distinct enough given the absence of sibling tools.

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 phrase 'required to discover AgentMesh' implies this tool is a prerequisite for further AgentMesh operations, giving some context for when to call it. However, there is no explicit statement of when to use it versus alternatives, and no alternatives exist. The guidance is more implied than explicit.

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