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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the safety profile is covered. The description adds what information is returned ('definition, active status and tools'), which is useful output-related context, but it does not add behavioral details such as permissions, error behavior, or rate limits.

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 no filler, front-loading the action and resource. Every word contributes to identifying the tool and its return contents.

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 burden of explaining return values, and it does state the main contents ('definition, active status and tools'). For a simple one-param read tool with strong annotations, this is largely complete, though it lacks detail on error cases or exact structure.

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?

Schema description coverage is 100% for the single 'name' parameter, so the schema already documents that it expects a toolset name. The description does not add format, constraints, or examples beyond what the schema provides, which is the baseline 3 when schema coverage is high.

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 ('Describe') and resource ('a toolset'), and adds the returned content ('definition, active status and tools'). It implicitly distinguishes from list_toolsets by being singular and detail-oriented, but does not explicitly name alternatives or fully sharpen the boundary with siblings.

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 guidance on when to use this tool versus list_toolsets, list_tools, or enable/disable_toolset. Usage is only implied by the verb 'Describe' and the required name parameter; no alternatives or exclusion conditions are stated.

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