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

Annotations already disclose readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so this is known as a safe, non-destructive read. The description adds value by specifying exactly what state is returned: installed MCPs, connection status, accounts, and catalog-tool counts. There is no contradiction with the annotations.

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?

The description is a single, front-loaded sentence that starts with the action and then efficiently enumerates the exact return categories. Every phrase earns its place, with no filler, repetition, or unnecessary detail.

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 the tool's low complexity (zero parameters), the strong annotations, and the absence of an output schema, the description provides a solid, complete overview of what the caller will learn. It could be slightly richer by mentioning whether the state is a live snapshot versus a cached summary, but that is a minor gap.

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?

This tool has zero parameters, so there is no parameter semantic burden on the description. The schema already covers everything by defining an empty object. The description appropriately indicates that no input is needed and instead focuses on output scope.

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 and object: "Returns the current toolkit state" and then lists what that includes — installed MCPs, connection status, connected accounts, and catalog tool counts. This clearly distinguishes it from sibling tools like show_version or report_bug by scoping it to toolkit/connectivity state.

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 implies it is used for inspecting the current toolkit/connection state, which is a clear context. However, it does not explicitly state when to prefer this over sibling tools such as show_version or authenticate, nor does it give any when-not-to-use guidance.

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