v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=true, and idempotentHint=true, so the safety profile is covered. The description adds useful context by saying it covers automatic-undo behavior and transport details, which are not visible in the annotations or schema. It does not elaborate on those behaviors, but for an introspection tool this is sufficient.
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, well-structured sentence with a colon-delimited list of exactly what the tool describes. Every word earns its place, and the most important content categories appear immediately after the verb.
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 parameters, no output schema, and simple introspection semantics, the description fully specifies what the agent will learn: backend, transport, automatic-undo behavior, and tool list. Nothing necessary for correct invocation is missing.
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. There are no parameter semantics to clarify, and the description correctly focuses on output content rather than inputs.
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 uses a specific verb ('Describe') and resource ('this Nuvio MCP server'), and enumerates the exact content areas: backend, transport, automatic-undo behavior, and full tool list. No sibling tool performs this meta-introspection role, so it is clearly differentiated from the operation-oriented sibling names.
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 makes it obvious that this tool is for obtaining a server-level overview, and there are no similar sibling tools competing for that use case. It does not explicitly state 'use this when...' or list exclusions, but the context is clear enough for an agent to know when to call it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
