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 safety profile is covered. The description adds valuable context about the exact content returned (installed MCPs, connection status, accounts, catalog tool counts), which is behavior beyond the annotations. No contradictions found.

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?

Description is a single, efficient sentence that front-loads the action ('Returns the current toolkit state') then lists the specific components returned. No wasted words, perfectly concise while conveying all necessary information.

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 fully enumerates the return content (installed MCPs, connection status, accounts, catalog tool counts). No output schema exists, but the description gives a clear mental model of the response. Given the low complexity and strong annotations, the description is sufficiently complete.

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?

There are zero parameters, so the schema provides no parameter details. The baseline for 0 parameters is 4, and the description does not need to explain parameters since none exist. The description focuses on the output, which is appropriate.

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?

Description clearly states the tool returns the current toolkit state with specific details (installed MCPs, connection status, accounts, catalog tool counts). It uses a specific verb 'Returns' and a precise resource, distinguishing it clearly from sibling tools like authenticate, connect, and marketplace which have different purposes.

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 clearly communicates the tool's purpose and output, implying use for checking toolkit status. It doesn't explicitly mention when not to use it or contrast with alternatives, but given the sibling list, it is self-evident that this is the status inspection tool and others are for action-oriented tasks. Lacks explicit exclusions, but context is clear.

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