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

No annotations are provided, but the description clearly indicates a read-only, non-destructive operation (returning metadata). It does not disclose any potential side effects or authorization needs, which are minimal for a metadata endpoint.

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 sentence that is well-front-loaded with the action and resource. Every word is purposeful with no redundancy.

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 no output schema, the description provides sufficient detail about the return content (version, data source, tool list). It is complete for a simple metadata tool, though it could mention if the list of tools is dynamic or static.

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 are no parameters, so the schema provides no meaning. The description compensates fully by explaining what the tool returns, adding value beyond the empty schema.

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 states it returns metadata about the server, listing specific fields: version, data source, tool list. The verb 'Return' and resource 'metadata about this MCP server' are precise, and the tool is distinct from siblings which deal with financial data.

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?

No explicit guidance on when to use or not use this tool. However, it's implied for initial server information retrieval, and sibling tools are clearly different in domain (financial data vs server metadata). A more explicit 'Use this to get information about the server itself' would improve.

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