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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering safety and idempotency. The description adds detail about returned content but does not disclose additional behavioral traits beyond what annotations already provide, so the baseline 3 applies.

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 primary purpose ('Returns the current toolkit state') and then efficiently lists the specific components returned, with no wasted words.

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?

Without an output schema, the description sufficiently lists what is returned (installed MCPs, connection status, accounts, catalog tool counts). This is complete for a query tool with no inputs, and the sibling context clearly positions it as the information retrieval tool.

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?

With zero parameters, the schema coverage is 100% vacuously. Per guidelines, a baseline of 4 is appropriate since no parameter explanation is needed and the description adds no irrelevant details.

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 explicitly states the tool returns the current toolkit state, listing specific details (installed MCPs, connection status, accounts, catalog tool counts). This clearly distinguishes it from sibling tools like connect, authenticate, and marketplace, which are action-oriented.

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 for querying toolkit state but does not explicitly specify when to use it over alternatives. It lacks guidance on exclusions or when not to use, though the context of read-only info tool is clear.

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