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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds only the content scope of the response; it says nothing about auth/permission requirements or whether settings are workspace-scoped to the caller's token.

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 with the resource named first and the returned fields second — front-loaded and free of filler. Nothing could be removed without losing content.

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, the description carries the return-value burden and does list the main setting categories, which is the right thing to spend words on. It stops short of indicating the response shape (flat vs nested objects) or that the field list is non-exhaustive, which is the remaining gap for a zero-param reader.

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 takes no parameters, so per the baseline there is nothing for the description to disambiguate. The schema is empty by design and the description correctly does not invent 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?

States a specific verb (Show) and resource (workspace defaults) and then enumerates the exact settings returned — alert limits, default alert channels, uptime target, response time limits. That enumeration distinguishes it from the adjacent vs_workspace_get and vs_workspace_settings_update without the agent needing to inspect schemas.

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?

Usage is only implied: it is a read-only getter for workspace-level defaults, so the when-to-use is inferable but never stated. There is no explicit exclusion telling the agent to prefer vs_workspace_get for general workspace metadata or vs_workspace_settings_update when it intends to change these values.

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