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

Annotations already declare idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds nothing beyond that: it does not say what enabling actually changes, whether an already-enabled toolset is a no-op, or whether enabling affects other sessions/users.

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 short, front-loaded sentence with no filler; the verb and resource lead. It is efficient, though almost too terse to carry any context.

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?

For a one-parameter toggle with no output schema and annotations covering idempotency, the description is minimally adequate. It nonetheless omits what the state change means and how it interacts with the disable/describe siblings.

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% and the single 'name' parameter is documented as 'Toolset name'. The phrase 'by name' in the description adds no meaning beyond the schema, so the baseline 3 applies.

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 and resource ('Enable a toolset'), so an agent immediately knows the operation. It does not, however, differentiate itself from the sibling disable_toolset or explain the relationship to describe_toolset/list_toolsets, so it falls short of a 5.

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?

There is no explicit guidance on when to enable a toolset versus inspecting it with describe_toolset or listing it with list_toolsets, nor any stated prerequisites. The intended usage is only inferable from the verb.

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