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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safely-read-only nature is established. The description adds useful context by listing what the returned toolkit state includes, though it does not disclose any caveats such as whether the state is cached, whether authentication is required, or what format the response takes.

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 well-structured sentence that front-loads the action ('Returns the current toolkit state') and then uses a list to enumerate the specific information returned. Every clause adds value and there is no redundant or filler 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?

For a zero-parameter, read-only status tool, the description is largely complete: it names the tool's purpose and the categories of information the user should expect. It could be marginally stronger by noting the response format or nesting, but given the absence of an output schema and the tool's low complexity, what is provided is sufficient.

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 schema coverage is effectively 100% and there are no parameter semantics for the description to clarify. As no parameters exist, the description does not need to add parameter-level detail; it instead appropriately focuses on the tool's output.

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 ('Returns') and clearly defines the resource ('current toolkit state'), then enumerates the exact contents: installed MCPs, connection status, connected accounts, and catalog-tool counts. This is specific enough to distinguish it from sibling tools like show_version, which would only report version information.

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 purpose implies the tool should be used whenever an agent needs an overview of the toolkit's installed integrations and their connectivity, but it never explicitly states when to prefer it over alternatives (e.g., show_version or connect). There is no when-not-to-use guidance, but the zero-parameter read-only nature makes the usage context reasonably clear.

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